jquery load with inline javascript

This works:

$.get( '/Pages/grid2.aspx', function ( data ) {
    $( '#mydiv' ).html( $( '<div></div>' ).html( data ).find( '#otherpagediv' ).clone() );
});

Live demo: http://jsfiddle.net/FRbnD/4/show/light/

To understand the demo, view the source code of both pages that comprise it:
Source code of the demo: http://jsfiddle.net/FRbnD/4/
Source code of the "other page": http://jsfiddle.net/MWkSj/1/

The idea is to retrieve the other page via a $.get request, and then find the #otherpagediv and clone it. You then append the clone to the #mydiv. If you insert a clone to the DOM and if that clone contains a SCRIPT element, that script will be executed.

From documentation:

Note: When calling .load() using a URL without a suffixed selector expression, the content is passed to .html() prior to scripts being removed. This executes the script blocks before they are discarded.

If .load() is however called with a selector expression appended to the URL, the scripts are stripped out prior to the DOM being updated, which is why they are never executed.

JavaScript should also come along the response. You have to make sure that /Pages/grid2.aspx should send the required response from server side. Also the url which you have passed to load method has a space in it. I think you should correct that and try it.

$('#mydiv').load("/Pages/grid2.aspx" + "#otherpagediv");

You might find this page helpful, I have used the script, it uses eval()

// this function create an Array that contains the JS code of every <script> 
// then apply the eval() to execute the code in every script collected
 function parseScript(strcode) {
 var scripts = new Array();         // Array which will store the script's code

// Strip out tags
 while(strcode.indexOf("<script") > -1 || strcode.indexOf("</script") > -1) {
 var s = strcode.indexOf("<script");
 var s_e = strcode.indexOf(">", s);
 var e = strcode.indexOf("</script", s);
 var e_e = strcode.indexOf(">", e);

 // Add to scripts array
 scripts.push(strcode.substring(s_e+1, e));
 // Strip from strcode
 strcode = strcode.substring(0, s) + strcode.substring(e_e+1);
}

// Loop through every script collected and eval it
for(var i=0; i<scripts.length; i++) {
 try {
   eval(scripts[i]);
 }
  catch(ex) {
    // do what you want here when a script fails
  }
 }
}
