You can also use JSTL Notation.

RE: Passing variable to _javascript_ function








Unfortunately it's not so easy, because you can't use a tag as an
attribute to the tag.

 validateDelete()" 

This can't work, because the attribute (onclick) will not be evaluated.

There could be two possible solutions. First, leave the html taglib and
drop back to normal 

Second: store the variable value in a _javascript_ variable:


 var myData = '';



 validateDelete(myData)" 

Of course this only works if you have the value of myData at page
generating time. If the value is changed by something the user does on
page, like checking a checkbox, i would store it in a hidden field in
the form and read per _javascript_ in validateDelete(), like this:
		 		 		 		 
for (var i=0;i < document.formname.elements.length;i++){
   var e = document.formname.elements[i];
   if (e.value == 'set' && e.checked==true){
		 doSubmit=true;
		 myData = e.value; 
   }
}

the above _javascript_ is only an example how to iterate over form fields
with _javascript_, it has not the required functionality.

Leon

RE: Passing variable to javascript function

[Anjishnu Bandyopadhyay]

Hi Anuradha,



I think this will work:



onclick="return validateDelete('')"

where "abc" is the java variable that you put in request/session.



With best regards,

Anjishnu.
