Executing Javascript with button

Question

How can I go about executing javascript with an item level button?
In the HTML DB 2 day tutorial it says this:
Calling a JavaScript from a button is a great way to confirm a request. Oracle HTML
DB actually uses this technique for the delete operation of most objects. For example,
when you delete a button, a JavaScript Alert Box appears asking you to confirm your
request. Consider the following example:
<script language="JavaScript1.1" type="text/javascript">
function deleteConfirm(msg)
var confDel = msg;
if(confDel ==null)
confDel= confirm("Would you like to perform this delete action?");
else
confDel= confirm(msg);
if (confDel== true)
doSubmit('Delete');
</script>
This example creates a function to confirm a delete action and then calls that function
from a button. Note that the function optionally submits the page and sets the value of
the internal variable :REQUEST to "Delete," thus performing the delete using a process
that conditionally executes based on the value of request.
Note that when you create the button you would need to select the Action Redirect to
URL without submitting page . Then, you would specify a URL target such as the
following:
javascript:confirmDelete('Would you like to perform this delete action?');
Can I only do this from a region button?

Answer 1

hi,
I have created a javascript form validation and finally (if its passes the validation) I am setting the :REQUEST as doSubmit('GO');
I am calling a conditional process with condition as request = expression1
with expression 1 as GO.
The javascript is as follows
function message_name_not_null(){
if(document.getElementById('P14_MESSAGE_NAME').value.length==0)
alert("Message Name is Mandatory!!");
return;
else if(document.getElementById('P14_MESSAGE_TEXT').value.length==0)
alert("Message Text is Mandatory!!");
return;
else
doSubmit('GO');
My problem is my process is not getting called in button click(I have called the javascript from this button as javascript:message_name_not_null(); in Optional URL Redirect section)
I have specified the :REQUEST value in the branches also.
Any sort of help please..
Thanks in Advance
