You could try to identify the element using jQuery class selector and calling innerHTML and assign it to a variable:

var val = $("class-selector").innerHTML

You won't be able to fetch it in a JS file. Since the model map will only be available when the server compiles and prints out the JSP page, the variables are available only in a JSP file and not in a JS file.

If you have a JS file and want to use it, you'll need to store the value in a variable in a JSP file and then access the variable in the JS file.

So, JSP code is:

var myVariable = ${val};

then put the JS file:

<script type="text/javascript" src="myfile.js">

Inside myfile.js, you can use the variable:

Ext.request({
  url : 'myUrl/'+myVariable,
  success:..
});
