Mix JavaScript and JSP

Hi.
I have jsp and javascript mixed when I click a check call a function javascript for example:
//JavaScript
function Hola(numerop) {
idRol = Number(numerop)
<%nombreRol = roles.get(numerop)%> }
//Form
<input type="checkbox" name="<%=roles.get(sum)%>" value="<%=roles.get(sum)%>" onClick="Hola('<%=roles.get(sum)%>')">
In the function numerop is a number but in the jsp code numerop is undefined.
How I can mixed javaScript and jsp??
Please I need help you.

Remember that the JSP runs on the server and generates the HTML, including Javascript. The Javascript runs on the browser after the JSP is finished. So you cannot do whatever it is you expected that to do.

Parameters b/w javascript and JSp

how i can pass values between javascript and jsp .
( java script varaible in the JSP part & jsp object in the javascript code )

Since Java script is on the client side , to get the value of a java script variable into jsp, u have to set some form field variable and submit it to the server again. So, it can be something like:
<script>
function submit()
     var scriptVar = 12;
     document.form1.formVariable.value=scriptVar;
     document.form1.submit();
</script>
<%
System.out.println("Script variable value = " +request.getParameter("formVariable"));
%>
<form name="form1" method="post">
<input type="hidden" name="formVariable" value=""/>
<input type="button" name="bSubmit" value="Submit" onclick="javascript:submit()" />
</form>
The first time this jsp is called, the value of formVariable will be null.
The next time, when u click on submit button, the value will be 12.
I have not tested this. There might be some syntax errors. Just try it out. Also, make sure that u don't end up submitting the form in an infinite loop by using the submit() generally in the script. Hope this helps.

Problem in JavaScript and JSP

Hello all, I have a problem. I am using a file upload box in my JSP page.
And I want to put some validations on the input of that file - see if it exists, check its size, or may be its type. I tried to use ActiveXObject in the JavaScript but it gives an error - ActiveXObject is not defined. Is not allowed to use ActiveX object in JavaScript. if not then where can we use such an object. I used such a FileSystemObject in VbScript, but that too was a independent running scripts like .vbs file. Can anybody help?

Use of ActiveX object is strongly discouraged, however
Check if this solution solves your problem
Inorder to use ActiveX Objects ,check whether ActiveX object s are enabled in IE.
Goto IE>Internet Options>Security Tab>click button Custom level>
scroll to 'Run ActiveX controls and plug-ins'>select �enable�.
also enable "Initialize and script ActiveX control not marked as safe."

Again combining javascript and jsp

can i do the post methode of a form inner a javascript function?
i want first check whether the reqiered fileds r filled and the do the post action.
Andre

Yeah that is really quite simple....
function FormValidation()
//do Validation stuff here
document.MyForm.submit;
<HTML><BODY>
<input type=submit name=submit value="Submit
onclick = "FormValidation(); return false;">
The return false will cancel the submit action.
null

Javascript and jsp forms

Hi,
I have the following java code what I am trying to do is to use some java script to read values from the buttons. As per my thinking the javascript code when called should print out the no of radio buttons but what it is giving is undefined. Could somebody point out what I ma doing wrong???????
Its already drawing me crazy.
<dsp:form name="students" action="../../check.jsp" method="post">
            <P>books </P>
      <INPUT type="radio" name="books" value="Java2InANutShell">
                               Java 2 in a nutshell
                      </INPUT>
                      <br><br>
     <input type="button" value="Length" id="length"      name="Log In" onclick="launchAutoWindow()"/>
</dsp:form>
function launchAutoWindow(id)
alert(document.students.books.length);
}

You only have one radio with the name of "books" on
the page.
If you have only one, "document.students.books"
evaluates directly to the radio object
If there is more than one object with that name, it
evaluates to an array of the objects. At that point,
length would be defined.
So if length is not defined, you know you only have
one :-)
Don't you just love javascript?Thanx mate. That solved the problem. I would have never figured it out myself. Thats kindaa silly but as long as it works ;)
Thanx again.

Embed javascript in JSP

hi
i want to store the query string of an URL in a flat file. but i want to append the name of the person who's passing the query string by prompting him to enter his/her name. i have a code something like this
FileWriter outputFile = new FileWriter("Libset1.txt", true);
BufferedWriter outputBuffer= new BufferedWriter(outputFile);
final PrintWriter outputWriter = new PrintWriter(outputBuffer);
//writes all data to the output file
for (int i=0; i<Selected_set1.length; i++)
outputWriter.println("some javascript to prompt the user goes here..." + Selected_set1);
outputWriter.close(); //closes output file
i want to embed some javascript in place "some javascript to prompt the user goes here..." prompting the user to enter his name..
is it possible to do that. if yes, how.?
sorry i'm just a beginner, it might look silly for you...please help...
thanks in advance..

First of all, you need to understand how Javascript and JSP work together....they don't. Javascript is a client side scripting language, which means that it executes and runs in the client browser after the page has been loaded. JSP is purely server side, it only runs while the request is being serviced, or while it's generating the HTML to send back to the client browser.
To do what you're asking for should be pretty easy using javascript. You should be able to use the Javascript onClick() event for the link the user is clicking on to execute a Javascript method that prompts the user for their name.
You might try something like this...
<script language="JavaScript">
function promptUser(newPage)
var username = prompt("Please enter your username");
if(username)
document.location = newPage + "&username=" + username;
}</script>
Click Here Please!
This will result in a query string that looks something like mypage.jsp?id=23&view=whatever&username=john
Make sense?

WL vs. WL-express and JSP vs. javascript/SQL

folks-
i am trying to convince a certain party to
disband a web-based job tracking system being
written in ASP, javascript, html, css and SQL.
it will be hosted on MS webserver running NT.
i am trying to convince them to use JSP and
WL express. i have done two years of EJB
component work on weblogic, however, i have not
done work with JSP or thin-clients. i was mostly
business-logic.
anyway i have some questions and need some
direction. i already know JSP is better than
ASP/javascript etc. because:
* ASP is proprietary. ditto for VBscript
* with an IDE creating JSP is easy and JSP
automatically creates servlets which is way
faster than by hand
* JSP is JAVA based and hence benefits from
all the portability pluses of JAVA
but here are the more difficult questions:
* why is WL express better than an MS
web server? (not including WL market share
and size. after all MS can claim that)
* since WL express does not have an EJB
container, how do you access the database?
via JDBC? does one just have JDBC code
floating around?
* since there is no EJB container how does
one separate presentation from logic from
data access? this is a major downside of
javascript, html, css and SQL etc.
* if a web app grows beyond JSP with WL express
into the need for an EJB container, i would
think that most of the app needs to re-written
as business-logic must be refactored into EJBs
and all JDBC code will be replaced by container
managed beans. this sounds a like a lot of
rework.
* isn't JSP slower than javascript as the
servlet and hmtl code is bounced back and
force across the network?
with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?

Use JDO or an OR-mapper or embed JDBC into your own data access classes.

one separate presentation from logic from

Presentation=JSP
Logic=Servlet
Data access=JDO or similar

You should be able to tell up front if it a tx-intensive app that requires
WLS.

They aren't exclusive. For dynamic pages, use Javascript on the front end,
JSP on the back.
* with respect to architecture, scalability,
and robustness what are the downsides to an
MS webserver and non-JSP coding?
In the real world, and for most apps, while Java has the architectural edge,
they both have similar scalability and similar robustness. MS gives you no
choice though, and you rewrite every time they see a new buzzword. You can't
leave MS-land without abandoning almost everything. You can leave WLS in a
week if you have to.
It's an investment. Invest wisely.

Mix formCalc and javascript in same event?

Hi Folks,
I have a bunch of formCalc and Javasript I'm trying to merge (two different forms, different programmers). Is it possible to mix javascript with formCalc in the same field event? If so, how?
thanks!

No, it is not possible to mix FormCalc and JavaScript in the same event. You will get run-time errors.

Javascript and Struts HTML problem

Hi all,
I write the following script in my jsp page, but this one does not produce the output at all :
<script type="text/javascript">
document.write("<input type="button" value='<bean:message key="btn.show"/>' onclick='onShowClick(this.form,"<bean:write name="vo" property="id"/>",true)'/>")
</script>While the following script without Javascript works as expected :
<input type="button" value='<bean:message key="btn.show"/>' onclick='onShowClick(this.form,"<bean:write name="vo" property="id"/>",true)'/>What is wrong ?
Thanks in advance,
Setya

Sure theres an easier way - don't use javascript?
Why do you want to do this javascript and document.write?
Can't you do it using JSP?
About the quotes:
The same quote that starts a string, ends it.
You are writing a javascript string, so the first unescaped single quote it comes across will end it.
Unfortunately in the middle of this string, you are writing HTML onclick event, with some javascript which ALSO needs quotes escaped(sigh)
So you have a javascript string producing some HTML, which also embeds a javascript string (now thats complicated quoting). Mixing the quotes with the struts tags just makes this a nightmare.
If you want to use quotes in the middle of a string you have to escape them.
Simple examples:
document.write("hello world"); // no quotes
document.write("hello \"Java\" "); // escaping the quotes
document.write('hello "Java" ') // because we used a different quote, we don't have to escape it
And mixing the two:
document.write(' hello "Java\'s buddy" '); // double quotes don't need to be escaped but the single quote does.Your line of code should be
document.write('<input type="button" value="<bean:message key="btn.show"/>" onclick="onShowClick(this.form,\'<bean.write name="vo" property="id"/>\',true)"')Note that I escaped the single quotes around the string attribute to the javascript method. Needed to do this, so as not to disturb the double quotes encapsulating the onclick="..." method.
Good luck,

FORM and JSP in the same page

Hello All
Is it possible to pass variable from a html textbox to a JSP? but they both are in the same page.
For this purpose, I have a created a index.html, which contain two frames, top.html and bottom.jsp. There is a textbox in the top.html, it collects 2 variables and use form action "POST" to call bottom.jsp to display a graph.
However after I run this page on Tomcat, it gave me error message in the bottom.html:
The server encountered an internal error () that prevented it from fulfilling this request.
Can anyone teach me how to solve this problem? Thanks a lot
Viola
index.html
===============================
(FRAME) top.html
<form action="bottom.jsp" method="post">
<input type="text" name="apple">
<input type="text" name="orange">
===============================
(FRAME) bottom.jsp
String apple = request.getParameter("apple");
String orange = request.getParameter("orange");
use those two variables to do something
and display a graph

The problem is that both pages are loaded @ the same time so when the getParameter gets executed the parameters are null and this is the probable cause of your error. Another problem is the action in form will cause the bottom to go into tops frame and not have anything to do with the other frame. If you want data to go from one frame to another while the user still sees them look @ DHTML, JavaScript and IFrames.

Mixing static and dynamic content in a single outputText value causes NPEs

Hi,
I am having a problem and I'm wondering if it is a result of my error or if this is a bug.
I am mixing dynamic and static content in the value attribute of tags (e.g., outputText). On initial page load, everything works fine. However, if the same view is reloaded (e.g., after a failed validation) I get an NPE from JSF:

<h:outputText escape="false"

<h:outputText escape="false"

          /><h:outputText escape="false" value='" rel="stylesheet" type="text/css" />' />So is the problem that I am mixing dynamic and static content with a single value? If so, why does it work on the first view, and not after?
If it matters, I'm using the reference implementation version 1.1 (as included with NetBeans 5.5RC2) on SuSE 10.0 w/ JDK 1.5_09.
Thanks,
Bill

Yes, that's how I originally had it, but then changed it to the outputText approach since a single tag could do what I wanted, as long as I was allowed to mix static and dynamic content within a single value.
I think this is a bug in JSF 1.1, since if what I am doing is illegal, it should throw an exception on the first page view, not work on first view and throw an exception on subsequent views. I'm guessing that this has something to do with the fact that on first page view it only runs the restore view and render response JSF phases, while on subsequent requests all of the phases will be run, and it's in one of those other phases that the exception is thrown.
For now, multiple tags is the work-around, I guess.

Associating two events with submit button using javascript in jsp

Hi
How can i Associate two events with submit button using javascript in jsp. Firstly it should insert the data to database and secondly it should close the same pop-up window

Have something like :
<input type="submit" name="submitbtn" value="Click me" onClick="function1(); function2(); " />
You just call both functions sequentially, it's that simple. Although using javascript to work with a database, that seems a bit tricky.

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.
I would be great if you could help me in this.
Thanks!!

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
