Javascript Problem

Prem
Member Posts: 88
Hi I am facing one issue
I have one jsp file which is having following javascript Fucntion
function myFunction(obj){
if(obj!=null){
<%
List<String> arrayList= new ArrayList<String>();
%>
var entry = obj.id
<% arrayList.add(%>entry<%); %>
<% request.setAttribute("arrayListAttribute",arrayList); %>
}
}
Above JS function is fired when some onlick event is get fired on some elements say.
Now Problem is I am not able to add that element's ID into arraylist . This jsp is not compiling due to this.
Please help me out.

I'll give a big hint: Java (JSP) executes on the server, Javascript is executed by the browser (the client). Do you still need to be told why you are horrible mistaken?

Hi ,
Yes I am aware about this , but questioned here so that some one can come up with alternative.
Do you have any alternative on this ? -
Hi.
I have done something similar in a project using ajax and php, but the basics should be the same.var request = new XMLHttpRequest(); function myFunction(obj){ if(obj!=null){ var entry = obj.id; request.open("GET", "http://yoururl/file.jsp?obj="+entry, true); request.sent(null); } }
Then in your jsp you can add the object into the arrayList. -

Ajax is one such alternative as the previous poster, simply resubmitting the page so it can rerender is another if ajax is beyond your skill level right now.
