Javascript function/inline

Application Express 4.0.2.00.07, XE 10g.
I have a button (Redirect to URL) with the following code -
javascript: this.form.P2_LOCATION.value= '';this.form.P2_HELP_CALL.value= '';this.form.P2_DUE_BACK.value= '';this.form.P2_NOTES.value= '';
and it works. When I try and change this to a function to tidy it up it doesn't work. I change the code on the button to -
javascript: clearfields();
and put the following in the "JavaScript/Function and Global Variable Declaration" section of the page attributes -
function clearfields()
this.form.P2_LOCATION.value= '';
this.form.P2_HELP_CALL.value= '';
this.form.P2_DUE_BACK.value= '';
this.form.P2_NOTES.value= '';
Pretty simple and basic I thought? But the function method doesn't fire... how come?!

instead of this.form.P2_LOCATION.value= '';try
$s('P2_LOCATION', '');.
May not answer your theoretical question, but I think it might fix the problem.

Javascript function undefined error

Hi developers,
I am generating a html file on the fly using a perl program. The main form to be used is generated by a javascript function called loadPage(). loadPage writes the <form> <input type="checkbox"> blah..</form> into the document by using document.write When the checkbox is unchecked, a javascript function called delFromList is called. This function is generated when the html is generated(by the perl program). The problem now is that the form comes out well but when I uncheck the checkbox, the javascript error says delFromList undefined...the same problem occurs for each function call...what am I missing here...any help will be highly appreciated...

As mentioned above javascript and java are 2 different thigns. How ever after looking at your code I would have to guess that you missed a '{' or '}' some where in you actual code. Other than some minor html syntax errors I realy didn't see anything wrong with the code above. But since you didn't post the actual code it hard to say if fixing the few minor errors would make any diff. I'm going with missed curly braces.

JavaScript function which fetches return_value from List of Values

Hi,
I have created List of Values named "NICKS". I want to write JavaScript function "get_workers_fullname(nick)" which returns display_value from List of Values. The parameter of function is return_value of List "NICKS".
I am new with this and don't know how to handle this case.
Please help me.

Hi,
The LOV, I mean is the item in Application's Shared Components. I don't mean the visible SelectList on the page.
This is what I found in ApEx's help: "A List of Values can be referenced by page items as well as report fields. It controls the values displayed and limits the user's selection. Lists of Values can be static (based on values you enter) or dynamic (based on a SQL query)."
I'd like to access values in such LOV from JavaScript. I am not sure it is possible.
Cheers,
Tom.

How to pass value to pop up window using javascript function?

function pop_up5()
var l_url=window.opener.document.getElementById("p_single_store_pc").value;
window.open(l_url, '''', ''fullscreen=no, scrollbars=1'');
</script>' );
Edited by: user11970612 on Jun 14, 2012 5:02 AM

this is probably due to the Javascript code and not a "real link" to another page... I don't know if the null is due to the Javascript...
But if you really really want to use javascript instead of a ... you can pass the location of the url with JSP (on your main page) as a parameter to the open window... (...) u can put instead of main.jsp <%= request.getServerName()+request.getRequestURI() %>
the value <%= ... %> will return something like test.com/html/main.jsp
Hope this helps.

How can I have a backing file call a JavaScript function?

I have a Weblogic portal with a JSP portlet. The portlet has a backing file. How can I get the backing file to call a JavaScript function in my portlet?
thanks

Hi
your questions are not correct because you are mixing up server side operations with client side operations.
First server side code executes then the page is sent to the browser , then any javascript executes on the browser. So asking for javascript to be called from backing file (server side) doesn't make sense or asking for javascript to read a parameter doesnt exactly work either.
However in your server code suppose you have a variable action in the request that you want javascript to know then in your JSP you would add something like
<script type="text/javascript">
var action = '${requestScope.action}';
alert(action);//or whatever you want to do
<c:if test="${requestScope.someOthervariable == ''xyz'}"><%-- this check is done on the server --%>
callSomeJavascript(); <%--this javascript is only executed when the server side value of someOtherVariable is xyz --%>
</c:if>
</script>
i.e. you can output the javascript that has the variables you need or the function calls you want.
Like I said understand whats server side and whats client side.

How can I call a custom javascript function when clicking on cfgrid cell.

I would like to call a custom javascript function when
clicking on a cell in an cfgrid (of html format). The closest thing
I can find is to use the HREF="" attribute, but it doesn't seem to
work with javascript inside it.
Simple example:
<cfgridcolumn name="Foo" header="Foo"
href="javascript:customFunction(#ID#);">
Do I need to tap into the underlying Ext JS funtionality? If
so, where can I start?
Thanks!

Hi,
According to your post, my understanding is that you want to hide/show list columns based on specify the permission for Users, SharePoint Groups or Active Directory Groups.
Here is a solution from CodePlex for your reference:

How can I call a servlet method from a javascript function

I want to call l a servlet method from a javascript function.
Does any one have an example of code.
Thinks in advance

Actually, as long as the servlet returns valid javascript, you can indeed "call it" from the client. It will initiate a request and return the result to the browser.
This example uses Perl, but it could be easily modified to go to a servlet instead.
Note that it is only supported in DOM browsers (IE6+/NN6+/etc)

Set multiple items with javascript function in chart link

Hi Folks
I am able to use the javascript $s function to set the value of one item from a chart link. I need to pass values to multiple items.
Is there a way to use javascript function to pass values for multiple items on a page from a chart link
Appreciate your responses
Thanks
Gopal

Hi Arnau,
You need to surround your JavaScript code like this (without the spaces before and after script):
< script language="Javascript">
window.open("<%=ABAP_VARIABLE%>").focus();
</script >

How to call a bean method through a javascript function

I dont discover any problems calling the bean method in this maner:
<%= helpdesk.data() %>
But, when I use a Button Onclick= to call the script function and which then is going call my bean method
an error on the page is reported!
I have include som code which gives you the idea of what Iam searching for. And is it possible to call
the bean method without doing from a new jsp page?
If you have any suggestions to why it doesnt work, please let me know.
I use Apache Tomcat 4.0
Best regards Micah.
<jsp:useBean id='helpdesk' scope='application'
class='helpdesk.testdb'/>
<html>
<head>
<script language="javascript">
function broadcast()
helpdesk.data();
</script>
</head>
<body>
<input type="button" value="Broadcast" onclick= broadcast()>
</body>
</html>

It's actually quite simple:
Beans run server-side
Javascript runs client-side
So you will never be able to run server-side-code thru the client...

Assigning return value of a javascript function to a variable

hi.
I have a javascript function which returns string.
I wanna assing return value of that function to variable.
for example:
<script>
funtion writeMe()
var ex;
ex="try"
return ex;
</script>
Then in body of JSP page. I wanna do something like:
<% String st;%>
Now I wanna assign the value that returned from writeMe function ("try") to st string.like:
<%st= writeMe();%>. but of course it doesn't work. how can I do that?

thnx. but actually what I want to do is sending some values produced by javascript to a barchart object. is it impossible too?
I mean my script function returns something like "100, 200, 300". I wanna pass that values to barchart. when I want to add aplet tag to jsp code instead of writing:
<param name="s1_value" value="100,200,300">
I want to write somethin like:
<param name="s1_value" value="myscriptfunction()">
is it possible in JSP? I saw an example like this in asp. it was like:
<param name="sampleLabels" value="<%call func1()>">. but in JSP it seems like call tag doesn't work. Is it possible in JSP?

I know that this is not the right forum, but I'd like peoples' advice on which prep to use for a colonoscopy. The Fleet's Phosphosoda prep is more palatable, and easier and more convenient to take compared to the Colyte (gallon jug) prep, but on the other hand the Colyte prep is safer since it doesn't carry the risk of calcium phosphate precipitates forming in the kidneys potentially causing acute kidney failure, a rare but certainly serious complication. Many thanks in advance.

Binding to a javascript function is not working

I am trying to use the following code to bind to a javascript
function and it's not working. I finally had to use jQuery to bind
the event handler, but I would like to see the CF generated stuff
work. Am I missing something here?
This jquery code is the workaround:
$('.match').change(function(){
updateSA(this);

Binding is not restricted to flash forms. I can bind directly
to a cfc without problems, but in this case I need to send more
info to the cfc than a single field would provide. You're supposed
to be able to bind to a javascript function using the syntax above,
but it's not working properly.

Help needed in calling a javascript function from a jsp

Hey guys,
I need help.
In my jsp I have a field called date. When i get date field from the database, it is a concatination of date and time field, so I wrote a small javascript function to strip just the date part from this date and time value.
The javascript function is
function formatDate(fieldName)
          var timer=fieldName;
          timer = timer.substring(5,7)+"/"+timer.substring(8,10)+"/"+timer.substring(0,4);
          return timer;
Now I want to call this javascript function from the input tag in jsp where I am displaying the value of date. Check below
This is one way I tried to do:
<input size="13" name="startDate" maxLength="255" value=<script>formatDate("<%=startDate%>")</script> onChange="checkDate(this)">
I even tried this:
<input size="13" name="startDate" maxLength="255" value="'formatDate(<%=startDate%>)'" onChange="checkDate(this)">
But it dosen't work
Please help. I am struggling on this for days.
Thanks,
Ruby
