Using javascript to clear up beans

i am using a jsp page that calls a java bean to connect to a database and run a query,
is it possible to use javascript to do a clear up on the java when the window is closed?
cheers

IOW, you shouldn't be passing an open connection to the view. Package up your query results in a bean and send that to the view, instead.

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,
              code: "Draw",
              name: "Draw"
</script>./resources/jar/Draw.jar - is the path and the name of the jar

Clearing shopping cart upon user logout using Javascript

Clearing shopping cart upon user logout using Javascript...
How is it done? Anybody got a script handy?
Thanks!

You'd need to obtain the CartID cookie, then call the function ClearCart('cd00d0e5-1822-4440-8293-32b8f317e363',0); where "cd00d0e5-1822-4440-8293-32b8f317e363" is the CartID you obtained from the cookie. The function should reside in one of the eCommerce JS files.

How do I use Javascript to populate a text field based on a selection from a drop down box?

Greetings,
I have virtually no experience with JavaScript and I am trying to figure out how to add some basic automation features to an Adobe form. I have a drop down box called "Hospital_Name" that will contain approximately 7 possible selections. When the user makes a selection, I would like to have the text field (called "Hospital_Address") below the drop down box populate with the corresponding address for the selection. I have the "Hospital_Address" text field configured for multiple lines and would like the address to have a line break between the street address and the city/state/zip.
For example, if the user selected "Hospital 1", the text field would display:
123 Main St
Anytown, CA 12345
Any help or examples you can provide would be greatly appreciated.

You have the element names within the object within brackets.
Make sure your brackets are properly placed and matched.
// Place all pre-population data into a single data structure
var Location = {
"--Hospital--":{ line1: " ", line2: " " },
"Bellevue Medical Center":{ line1: "2500 BMC Drive", line2: "Bellevue, NE 68123" },
"CHI Bergan Mercy":{ line1: "7500 Mercy Road", line2: "Omaha, NE 68124" },
"CHI Immanuel":{ line1: "6901 N. 72nd Street", line2: "Omaha, NE 68122" },
"CHI Lakeside":{ line1: "16901 Lakeside Hills Court", line2: "Omaha, NE 68130" },
"CHI Midlands":{ line1: "11111 S. 84th Street", line2: "Papillion, NE 68046" },
"Creighton University Medical Center":{ line1: "601 N. 30th Street", line2: "Omaha, NE 68131" },
"Nebraska Medical Center":{ line1: "4400 Emile Drive", line2: "Omaha, NE 68105" }
// some debugging code to see location names;
console.show();console.clear():
for(I in Location) {
console.println(I);
// end debugging code;
function SetFieldValues(Hospital_Name) {
    this.getField("AddLine1").value = Location[Hospital_Name].line1;
    this.getField("AddLine2").value = Location[Hospital_Name].line2;
This is not a beginners task but requires a fair amount of knowledge about the structure of objects, defining strings, and structure of arrays.
Are you sure you have all the field names correctly spelled and capitalized?
Do you get any error in the JavaScript console?
Just trying the line that defines the "Location", I get the following error:
SyntaxError: invalid property id
1:Console:Exec
undefined
All the form field in a PDF are processed by using JavaScript and any error in any script will stop JavaScript processing.
It might help to have a link to the problem form.
Make sure your brackets are properly placed and matched.
// Place all pre-population data into a single data structure

How to Read Variable Values in WAD 7.0 Using JavaScript

Problem using javascript to submit jsf form, values not submitted

Greetings!
I have a t:selectOneMenu where I want the page to be submitted when they change the selected value. At this point, I am able to get the form to submit and reload the page, which is all fine. The problem is that none of the values from the page are not set in the backing bean. I have break points on the setter methods that are not being hit.
I have tried a number of things from searching multiple forums, but here are snippets from my latest version...
<h:form>
<t:commandLink id="hiddenLink" forceId="true" value="test link"
action="#{pc_PageX.doBtnHiddenLinkAction}"></t:commandLink>
<t:selectOneMenu id="pageList_top" forceId="true" value="#{pc_PageX.ValueX}"
     onchange="jspellSync(); submitPageX();">
     <f:selectItems value="#{pc_PageX.ListX}" />
</t:selectOneMenu>
</h:form>
function submitPageX(){
     var hiddenLink = document.getElementById("hiddenLink");
     hiddenLink.click();
}Note that the <t:commandLink> is not hidden, though it will be in the final version if I can get this to work.
If I click the commandLink myself, the page is submitted with all the page values as expected. If I change the list value, thus using javascript to fire the commandLink's click event, the page is submitted with NO values.
Can anyone come up with an explanation for this behavior? Or better yet, a solution?
A couple other things I've tried...
- Not using a commandLink and using jsf's submit function -> onchange="jspellSync(); submit();"
- Clicking the link using other ways -> hiddenLink.fireEvent('onclick');
If all else fails, I'll just add a button that they have to click to submit the form.

I recall this problem in one of the ancient JSF versions. Which JSF version do you use? Do you have any room to upgrade to latest? We're using an IBM implementation of JSF, which is at version 7.0. The IBM implementation appears to be built on the JSF base 1.1.That's not an IBM JSF implementation, they do not have any one, they just have some component libraries which runs on top of some JSF implementation. RAD/WSAD ships by default with Sun JSF RI. Try upgrading to at least 1.1_02 which you can download from the aforementioned link. There's a gap of 2 years (and inherently a lot of bugfixes) compared to 1.1. If the application server used supports Servlet 2.5, you could even upgrade to the latest 1.2.
We've had other issues with the IBM implementation, which could be the cause in this case too. We've been talking about switching to MyFaces, but there is one feature of the IBM version that we like. It's basically a script collector (hx:scriptCollector) that allows us to do pre-processing on the page.As said before, IBM does not have a JSF implementation. So replacing RI by MyFaces wouldn't make any difference.

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.
I have one more question...I have gone through the JSP samples in OTN and I am trying do download the sample 'Travel servlet' which show list of countries...etc
I have also gone through the 'readme' but I don't know how to extract .jar file.

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 Redirect to another page Using JavaScript in ADF Faces?

Hi Guys,
I have a UI user case that has a af:menu which contains mutiple af:goMenuItem. When user click on the menu, the menu slides down and shows up the af:goMenuItem. As we know, you could define the page destinations in af:goMenuItem to go to another page when user clicked, but af:menu itself cannot be redirected to another page. Well, the user case wants the menu itself could be redirected if user click on it.
So I am thinking using JavaScript to do this: when the af:menu gets clicked, redirect to another page. BUT, I looked over the ADF Faces Javascript API and was not able to find that piece of code to do this. Any help???
Another work around for the user case scenario is to use HTML marks + CSS/JavaScript instead of af:menu and af:goMenuItem but this changes the scope of technology although it's not hard to do
Any other idea to accomplish the user case other than what I could think of ?
Thanks Guys!

Hi,
1 - you can have a hidden command item to do the navigation based on a control flow case. In this case, you access the command component from JavaScript create a new ActionEvent and queue it
2 - JavaScript can use an af:serverListener to call into a server side managed bean method to perform the navigation
there is no JavaScript API for navigation in ADF Faces because navigation in JavaServer Faces is an event driven framework and we don't support developers fighting the framework.

Pre-validation using JavaScript cannot work in JSF?

Sometimes we need to do pre-validation using JavaScript in some senarios that data need be entered and validated at client site before it reaches to Web Application Server. Remind that JSF is a server validation. Creator seems not to allow Developers to do pre-validation using JavaScript for any editable input fields in form. I will illustrate an example and hope anyone can help me to solve it out.
Assume that if we write the a new web page that allows User enters Name and Phone. The pre-validation function called test() is written in JavaScript for validating field Phone. For simplicity, the below HTML/JavaScript without nested in table is a simple one for HTML form.
<html>
<body>
<script language="JavaScript">
function test(){
     if (form1.phone.value == "")
          alert("Please enter phone number in digits.");
          return false;
</script>
<form name=form1>
<input id="phone" type="text" size=20><Br>
<input id="name" type="text" size=20><Br>
<input type="submit" id="submit" onclick="test()" value="Submit">
</form>
</body>
</html>
Now, we consider using Java Studio Creator to generate the same form as describing above. The script is shown below:
<?xml version="1.0"?>
<jsp:root version="1.2" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page">
<jsp:directive.page contentType="text/html;charset=UTF-8"/>
<f:view>
<html>
<head>
<title>testForm Title</title>
</head>
<body rave-layout="grid">
<h:form binding="#{testForm.form1}" id="form1">
<h:inputText binding="#{testForm.textField1}" id="phone" style="position: absolute; left: 192px; top: 96px; width: 168px; height: 23px"/>
<h:inputText binding="#{testForm.textField2}" id="name" style="position: absolute; left: 192px; top: 144px; width: 168px; height: 23px"/>
<h:commandButton binding="#{testForm.button1}" id="submit" style="position: absolute; left: 192px; top: 216px" value="Submit"/>
</h:form>
</body>
</html>
</f:view>
</jsp:root>
After running Script that Creator created, the HTML is generated and reduced (for simplicity) as follows:
<f:view>
<html>
<body rave-layout="grid">
<form action="/rave/rave" id="form1" method="post">
<input id="form1:Phone" type="text"></input>
<input id="form1:name" type="text"></input>
<input id="form1:button1" value="Submit" onClick="test()"></input>
</body>
</html>
</f:view>
Take a look carefully at <input> elements. We see the syntax for naming for each "input" element that there is a semi colon added between form1 and phone or form1 and name. This syntax is generated from built-in JSF components. Hence, I rewrite the test() JavaScript function to match with the naming that Creator generated as follows:
<script language="JavaScript">
function test(){
     if (form1.form1:Phone.value == "")
          alert("Please enter phone number in digits.");
          return false;
</script>
Clearly, this JavaScript cannot be worked because of a semi column that Creator has named it.
I have tried to work arround for this but cannot find a solution except changing the name such as: from <input id="form1:phone" ...> to <input id="form1_phone" ..>. But I could not change or modify the scripts because it is generated from JSF components when running it under browser.
I guess to solve this problem, the naming for elements in form should be reconsidered in the next release of Java Studio Creator.

Reset report pagination using javascript / ajax ?

Hiho,
i have a page where i pull a ppr report from a different page using htmldb_get like described in Carls excellent examples. The first page also contains a textfield to set a where condition in the report, for examle to search a streetname..
Now i need a way to reset the pagination of the report using javascript.
Example:
I search for street_name_1 and the report returns 100 rows, 10 rows on each page. Now i use the pagination links to switch throught report pages to page 5.
Now i search for street_name_2 and the report returns 5 rows, so this would only be one page in the report. But the report pagination still is on page 5, so no results are shown. And no pagination buttons either.
What can i do to reset the pagination before i pull the report without submitting the page?
Thanks for help,
DIrk

I have similar problem with AJAX report pagination. When I click the pagination for next set of rows, it gives "undefined" error. I'm trying to call "get.clear('RP');" in the javascript function as susggested in above url, but doen't work. any examples are appreciated.
thanks,
Surya

Scrolling component into view programmatically without using javascript

Hi,
Is it possible to scroll an adf component into view programmatically without using javascript?
I know of <af:scrollComponentIntoViewBehaviour> that can be added to a command component , but is there a way to do that programmatically in a bean?
Problem with using javascript is its not guaranteed to work in different browsers.
Regards,
Rakesh.

Hi John,
Thanks for the reply.
If i use the af:scrollComponentIntoViewBehavior, then i wont be able to achieve my desired functionality.
In my use case, i want the id, of the component that needs to be scrolled into view, to be determined in the server listener of the button which is not happening.
Code snippet in jspx page is as follows:
<af:commandButton id="cb1" immediate="true">
<af:clientListener method="clickButton" type="click"/>
<af:serverListener type="customEvent"
method="#{pageFlowScope.bean.doScroll }"/>
<af:scrollComponentIntoViewBehavior id="#{pageFlowScope.bean.compId}/>
</af:commandButton>
And the java code for method doScroll is something like :
public void doScroll (ClientEvent clientEvent)
//logic to determine compId goes here
compId = "id";
So, the problem here is "compId" is set to some value when bean is loaded and the id in the af:scrollComponentIntoViewBehavior will be set to that value forever.
I cant find any way of telling it to re-read the "compId" value, say after clicking the button. I can refresh the button in the server listener to update the compId .
But the updated compId will come into picture from *next click*. This is because, after the button is clicked, "scroll" action happens first and then serverListener executes.
Is there a way to change order of this execution like "execute server listener first and then do the scrolling thing" ?
Regards,
Rakesh.

Activate (or change focus) on ADF Paneltab using javascript

Hello,
I am trying to embed an oracle form inside ADF page. I need to activate or change focus on an adf panel tab when I click on a link. I need to use javascript for this as I cannot afford a trip to the server (and hence a backing bean is not an option), as every time the page refreshes the form loses its session. Is there a way to activate/disclose a paneltab using javascript?
Regards,
Anirban

This problem seems to be resolved. We can use javascript as well as a managed bean to do this. I was missing the setDisclosed(true/false) function. The best part is, even without a partial trigger or a partial submit, we can do this without refreshing the page when using a managed bean.
When using javascript, we can use the below method:
function f1(event) {
var v1 = event.getSource();
v1.setDisclosed(true);
}

Replacing images using Javascript

There are several posts explaining how to replace an image using Javascript (simpler with JQuery), but when I tried the code, the image kept reverting to the original image specified. This occurred regardless of browser, but does not revert in DW's "Live View". It turns out the culprit is that I was using an anchor <a> with a href attribute. The browser apparently evaluates the href after processing the OnClick() event. Switching to a button versus an anchor solved the problem. DW needs a little tuning.

If you show us your code that wasn't working we'll be happy to recommend
Don't need to see code. The explanation was clear enough to determine the cause of issue. <a href="somefile.ext" onclick="somefunction();">click</a> is going to somefile.ext immediately after triggering the onclick event on the page. Lookup return false; for the solution of using onclick event in an anchor tag.
