How to use Javascript to validate values....

Hello :
I have the following piece of code in my jsp
<script>
function doSubmit()
if (!validate())
return;
document.create_request.action="ibu_conf_sr.jsp;
document.create_request.submit();
function validate()
with (document.create_request) {
if (document.create_request.sei_summary.value == '') {
alert('Please enter Summary');
return false;
</script>
<form method="post" name="create_request" action="ibu_cr_sr.jsp" >
<tr>
<td align="right" valign="top" nowrap>  </td>
<td align="left" valign="top" nowrap>  
<!--input type="submit" name="search" value="Submit Service Request"-->
               <input type="button" value="Submit" onClick="doSubmit()">
<input type="reset" name="Clear3" value="Clear">
</td>
<td width="13%"> </td>
</tr>
</form>
I have a Submit button which will trigger the Java script doSubmit which in turn should Validate the values for one of the fields in the form ibu_cr_sr.jsp and only if the field has a value should it forward to the next page, ibu_conf_sr.jsp
For some reason I am not able to get this to work.. what am I missing ?

That's funny because it works for me. Cut and paste the following into a text file, name it test.html and open in IE. then try it.
<html>
<head>
</head>
<body>
<script>
function doSubmit()
if (!validate()) { return false; }
document.create_request.action="ibu_conf_sr.jsp"; //Added "
document.create_request.submit();
function validate()
if (document.create_request.sei_summary.value == "") {
alert('Please enter Summary');
return false;
return true;
</script>
<form method="GET" name="create_request"  >
<input type=text name="sei_summary">
<tr>
<td align="right" valign="top" nowrap> </td>
<td align="left" valign="top" nowrap>
<!--input type="submit" name="search" value="Submit Service Request"-->
<input type="button" value="Submit" onClick="doSubmit()">
<input type="reset" name="Clear3" value="Clear">
</td>
<td width="13%"> </td>
</tr>
</form>
</body>
</html>

  • How to Use JavaScript in Controller Class...

    Hi All,
    Can any one tell me how to use JavaScript in Controller Class.
    Requirement is:
    I have
    Radio Group(RG1),
    Two Radio Buttons(RB1,RB2),
    Two messageTextInput(MTI1,MTI2),
    if i click RB1 i should Prompt to the end user to "Enter value for MTI1" or
    If i click RB2 i should prompt "Enter value for MTI2" while submitting page.
    Please let me know the steps to use JavaScript and the above client validation...
    Regards
    Alem...

    Using javascript is against the standard. I can tell you a workaround instead of you setting the javascript, check if that would be acceptable.
    You can use PPR and set the required property on the messageTextInput on clicking of the radio button. By doing this you will let UIX generate the javascript for you to handle the client side validation. But the validation will happen only on click of the submit button. The visual indicator is good enough to tell that the value has to be entered to the item.

    We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
    Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
    Do you know of any way to dynamically query the the Oracle database in Javascript

  • How to use Javascript to load random pages?

    I wonder if anyone knows how to use Javascript to load a list
    of links stored in the text file.
    Every address will take a line, and the Javascript will
    randomly select one of the addresses to load.
    The user will click the button "random" and access the page
    randomly selected by the script.

    Addition note:
    I forgot to say this because my computer froze......(how
    lame)
    I got the code for random accessing the links.
    But now the problem is, is there anyway to parse a text file
    into the array in Javascript?

  • How to use JavaScript in Web bean generated JSP

    I want to do some simple JavaScript validations (for example, checking if a particular field is empty) in the JSP page rendered by the data web bean. Because the HTML is rendered by the bean, I'm not able to refer to the HTML controls in the JSP page. I'm not even able to refer to the form with the following standard piece of JavaScript code - "document.forms[0].control_name".
    Is anybody aware of how to use JavaScript with these rendered JSP pages?

    You just have to add it like and applet , including this line in your JSP or JSF
    <script src="http://dl.javafx.com/dtfx.js"></script>Then add the applet
    <script>
        javafx(
                  archive: "./resources/jar/Draw.jar",
                  width: 400,
                  height: 200,

  • How to use Javascript in OBIEE?

    Hi all,
    can any one tell how to use javascript in OBIEE. i.e steps to follow to insert the javascript in OBIEE 11g or 10g

    If you are trying to display total number of pages in a report, Add the below formula in the column of the report and hide that column in the report.
    FX = sum(count(1))/25
    You can then reference the column in the narrative view like this: "Total pages in the report are @5" and out put may be "Total Pages in the report are 30".
    Or
    You can also use something like the below:
    To calculate them use fi:
    CEILING(CAST(RCOUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the page number
    CEILING(CAST(COUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the total pages
    Put the above formula in the column and reference it in the narrative view like I mentioned in the previous example.
    If you are report view is pivot, then please refer to this link: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-pagination-in-pivot-tables/

  • How to use JavaScript to supply a value for a MessageTextInput field

    With the text attribute you can supply a deafult value for text field. Is it possible to supply this field with a default value determined by javascript ?
    <messageTextInput name="startDate" text="..." ...

    Marcel,
    If you want to dynamically set a value for a text field, there are two approaches you can use:
    1. use javascript (the browser language) and then for your <body> element's onload handler, invoke a javascript method that sets your form value.
    2. use java (the compiled language) and databind the "text" attribute of messageTextInput to a dataobject that gives the current date. If all you're looking to do is bind to the current date, I'd recommend this approach.
    Hope this helps,

  • How to use Ajax Get Multiple Values in Tabular form?

    Hi All-
    I am trying to use AJAX to get multiple values in tabular form by using Denes Kubicek's example in the following link -
    http://apex.oracle.com/pls/otn/f?p=31517:239:9172467565606::NO:::
    Basically, I want to use the drop down list to populate rest of the values on the form.
    I have created the example(Ajax Get Multiple Values, application 54522) on Oracle site -
    http://apex.oracle.com/pls/apex/f?p=4550:1:0:::::
    Workspace: iConnect
    login: demo
    password: demo
    I was able to duplicate his example on page 1 (home page).
    However, I want to use system generate tabular form to finish this example, and was not able to populate the data correctly.
    Page 2 (method 2) is the one that I am having trouble to populate the column values. When I checked application item values in Session, and the values seems to be populated correctly.
    This is what I have done on this page:
    1. Create an Application Process On Demand - Set_Multi_Items_Tabular2:
    DECLARE
      v_subject my_book_store.subject%TYPE;
      v_price my_book_store.price%TYPE;
      v_author my_book_store.author%TYPE;
      v_qty NUMBER;
      CURSOR cur_c
      IS
      SELECT subject, price, author, 1 qty
      FROM my_book_store
      WHERE book_id = :temporary_application_item2;
    BEGIN
      FOR c IN cur_c
      LOOP
      v_subject := c.subject;
      v_price := c.price;
      v_author := c.author;
      v_qty := c.qty;
      END LOOP;
      OWA_UTIL.mime_header ('text/xml', FALSE);
      HTP.p ('Cache-Control: no-cache');
      HTP.p ('Pragma: no-cache');
      OWA_UTIL.http_header_close;
      HTP.prn ('<body>');
      HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
      HTP.prn ('<item id="f04_' || :t_rownum || '">' || v_subject || '</item>');
      HTP.prn ('<item id="f05_' || :t_rownum || '">' || v_price || '</item>');
      HTP.prn ('<item id="f06_' || :t_rownum || '">' || v_author || '</item>');
      HTP.prn ('<item id="f07_' || :t_rownum || '">' || v_qty || '</item>');
      HTP.prn ('</body>');
    END;
    2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
    3. Put the following in the Page Header:
    <script language="JavaScript" type="text/javascript">
    function f_set_multi_items_tabular2(pValue, pRow){
        var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
    'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
    if(pValue){
    get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
    get.add('T_ROWNUM2',pRow)
    }else{
    get.add('TEMPORARY_APPLICATION_ITEM2','null')
        gReturn = get.get('XML');
        if(gReturn){
            var l_Count = gReturn.getElementsByTagName("item").length;
            for(var i = 0;i<l_Count;i++){
                var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
                var l_ID = l_Opt_Xml.getAttribute('id');
                var l_El = html_GetElement(l_ID);   
                if(l_Opt_Xml.firstChild){
                    var l_Value = l_Opt_Xml.firstChild.nodeValue;
                }else{
                    var l_Value = '';
                if(l_El){
                    if(l_El.tagName == 'INPUT'){
                        l_El.value = l_Value;
                    }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
                        l_El.parentNode.innerHTML = l_Value;
                        l_El.parentNode.id = l_ID;
                    }else{
                        l_El.innerHTML = l_Value;
        get = null;
    </script>
    Add the follwing to the end of the above JavaScript:
    <script language="JavaScript" type="text/javascript">
    function setLOV(filter, list2)
    var s = filter.id;
    var item = s.substring(3,8);
    var field2 = list2 + item;
    f_set_multi_items_tabular2(filter, field2);
    4. Tabular form query:
    select
    "BOOK_ID",
    "BOOK",
    "SUBJECT",
    "PRICE",
    "AUTHOR",
    "QTY",
    "BOOK_ID" BOOK_ID_DISPLAY
    from "#OWNER#"."MY_BOOK_STORE"
    5. In Book_ID_DISPLAY column attribute:
    Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
    Changed to -> onchange="javascript:setLOV(this,'f03');"
    Now,  T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
    Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!

    Updated code in Red..

    Ling
    Lets start with looking at what the javascript code is doing.
    function f_set_multi_items_tabular(pValue, pRow){
      /*This will initiate the url for the demand process to run*/
      var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
                              'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
      if(pValue){
        /*If there is an value than submit item name with value*/
        get.add('TEMPORARY_APPLICATION_ITEM',pValue)
        get.add('T_ROWNUM',pRow)
      }else{
        /*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
        get.add('TEMPORARY_APPLICATION_ITEM','null')
      /*Submit the url and te returned document is of type XML*/
      gReturn = get.get('XML');
      if(gReturn){
        /*There is something returned*/
        var l_Count = gReturn.getElementsByTagName("item").length;
        /*For all elements of the tag item*/
        for(var i = 0;i<l_Count;i++){
          /*Get the item out of the XML*/
          var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
          /*Get the id of the item*/
          var l_ID = l_Opt_Xml.getAttribute('id');
          /*Get the element in the original page with the same id as
          **the item we have in the XML produced by the ondemand process
          var l_El = html_GetElement(l_ID);
          /*Now get the value of the item form the XML*/
          if(l_Opt_Xml.firstChild){
            var l_Value = l_Opt_Xml.firstChild.nodeValue;
          }else{
            /*There is no value*/
            var l_Value = '';
          if(l_El){
            /*There is an element with the same id as the item we are processing*/
            if(l_El.tagName == 'INPUT'){
              /*The element is an input item just set the value*/
              l_El.value = l_Value;
            }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
              /*If it is a span elment and has the class grabber
              **Then set the innerHTML of the parent to the value
              **and the id of the parent to the id
              l_El.parentNode.innerHTML = l_Value;
              l_El.parentNode.id = l_ID;
            }else{
              /*Else set the value as innerHTML*/
              l_El.innerHTML = l_Value;
      get = null;
    Now where it went wrong in your initial post
    The XML that was returned by your XML process would be something like
    <body>
      <desc>this xml genericly sets multiple items</desc>
      <item id="f02_1">CSS Mastery</item>
      <item id="f03_1">22</item>
      <item id="f04_1">Andy Budd</item>
      <item id="f05_1">1</item>
    </body>
    When you don't use apex_item to create your tabular form a item in the table will look like
    <input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
    Notice the id's f02_1 and f02_0001 don't match.
    So to make it work the XML would have to look like
    <body>
      <desc>this xml genericly sets multiple items</desc>
      <item id="f02_0001">CSS Mastery</item>
      <item id="f03_0001">22</item>
      <item id="f04_0001">Andy Budd</item>
      <item id="f05_0001">1</item>
    </body>
    To do that simply use lpad in the ondemand process like
    HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
    HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
    HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
    HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
    Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.

  • How to use JavaScript in Dynamic commandLink

    Hi All,
    In my JSF application, I am able to get the dynamic CommandLink with the below mentioned code.
    commandLink.setActionExpression(createActionExpression("#{myBean.myMethod}", String.class));
    The above code is navigating to the page mypage.jsp properly (the page which is returned by method myMethod).
    My Question is: Instead of navigation (as mentioned above) I want to generate a popup window using JavaScript on click of commandLink.
    Please suggest me on how to proceed on this?

    Hers is my JavaScript:
    function showPopupWindow(action) {
    formId=action.form.id;
    //features="height=300,width=250,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes";
    features="toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=no,width=900,height=500,top=80,left=80";
    winId=window.open('Mypage.faces','list',features); // open search window
    winId.focus();
    This works perfectly with the onclick attribute of the commandbutton as shown below:
    <h:commandButton value="Open Popup" onclick="showPopupWindow(this); return false;"></h:commandButton>
    {color:#ff0000}
    But I tried same thing with the onclick attribute of the commandLink, that did not work.
    <h:commandLink value="Open Popup" onclick="showPopupWindow(this); return false;"></h:commandLink>
    {color:#0000ff}As per my requirement, I tried using setOnclick attribute in the following manner, that failed to open the popup:
    commandLink.setOnclick("{color}{color}*{color:#0000ff}showPopupWindow(this); return false;{color}*{color:#ff0000}*{color:#0000ff}");{color}*
    {color}

  • How to use javascript and sql

    Hi,
    I am new to HTML DB. I am trying to populate some textfields once a a drop down menu is selected .
    But my information to populate need to be obtained by querying my dabase how do i do that? using javascript
    or is there another way of doing that without using javascript?

    I understand you don't want to actually "submit" the page. Undsertand that with the web, you either:
    1. bring all of the values from the server to the page with you
    2. go back to the server to get values based on the value of the lov, or
    3. do partial-page refresh and get the new values from the server in the background with some VERY challenging javascript.
    2 is the solution I am suggesting. Do not insert the values yet, just let HTML DB save them in your session state. As soon as you change the LOV the page will be submitted and return with the correct values in the related items. If you want to get fancy, you can choose not to show the related items until the user has selected a value from the LOV.
    To see an example of this (kind of), go to the SQL Workshop and click on the "Tables" Icon. Now you should see a list of the tables in your schema. Change the "Type" LOV from table to index. Notice the page refreshed and the report changed? I'm suggesting the same concept, but just changing the value of some items, not a report.

  • How to use JavaScript to Open a link automatically

    Is there a method (using JavaScript) to allow a user clicked link to open the link through a “intermediary” page?
    For example, say I have a web page with a embedded Flash file that contains links to several different (outside) web pages. The behavior I want is that the user clicks a link (within the Flash file), a HTML window opens (over the 1st HTML/Flash window) with the new content, leaving the original Flash/HTML window displayed in the background. The user reads the new content. The user can then close the newer window and be back at the displayed HTML/Flash file.
    The twist is that the link embedded in the referring Flash/HTML file goes to a “intermediary page”. Call that the “collector” page. I control that page. On that page I have collected (in a list) all the actual outside URLs (I do this so that I can easily change the URLs using HTML rather than having to edit the Flash file.) The Flash file contains essentially the same URL for each outside location (plus a variable unique to a specific URL).
    The user should not ever actually see this intermediary/collector page. Instead, they click the link, a variable is passed from the referring page to the collector page and fires the corresponding link automatically (replacing the content in the newly created window). Since the link fires automatically the content in the new window (initially created by the collector page) changes to the destination content.
    Is this possible?
    What JavaScript functions are used?
    How are the referring links constructed in the Flash so the variable is passed to the collector page?
    How does the “collector” page auto open the actual content?
    If anyone can point me to descriptions on how this might be done I’d certainly appreciate it.

    >is there a way i can call javascript without security checking?
    It wouldn't be security if you could just bypass it. Did you read all
    the security notes? You might be able to do something with trusted
    functions, but I'm not sure how that would integrate with a plug-in.

  • Using JavaScript to set value of Spry validated text field

    Why can't the value of a text field be set using JavaScript
    when it's validated using the Spry validation widget.
    Example (this works):
    <select name="birthdate_month" id="birthdate_month"
    onChange="document.getElementById('birthdate').value = 'test';">
    <option>1</option>
    <option>2</option>
    </select>
    <input type="text" name="birthdate" id="birthdate"
    value="">
    Example (this doesnt work):
    <select name="birthdate_month" id="birthdate_month"
    onChange="document.getElementById('birthdate').value = 'test';">
    <option>1</option>
    <option>2</option>
    </select>
    <span id="birthdate">
    <input type="text" name="birthdate" id="birthdate"
    value="">
    <span class="textfieldRequiredMsg">please enter your
    birthday</span>
    </span>
    <script type="text/javascript">
    <!--
    var birthdate = new
    Spry.Widget.ValidationTextField("birthdate", "none");
    //-->
    </script>
    Is there a way to change the value of a Spry validated text
    field using JavaScript?
    Thanks.

    Why can't the value of a text field be set using JavaScript
    when it's validated using the Spry validation widget.
