JQuery popup new window from ASP.NET page

/ Published in: JavaScript

This can be put into a utility class in your ASP.NET project and put onto the page with ScriptManager.RegisterStartupScript(). The script alters the ASP.NET __VIEWSTATE value which somehow validates requests; if you leave it out the popup wont work.

Copy this code and paste it in your HTML

$(document).ready(function() {
 
    //get the current URL
    var originalUrl = $('form').attr('action');
 
    //change the ASP.NET ViewState value so .NET doesn't break
    $('#__VIEWSTATE').attr('name', 'name');
 
    //the new URL
    var url = 'MyPopup.aspx';
 
    //find the form, and change its url
    $('form').attr('action', url).attr('target', '_blank');
 
    //post the form
    $('form').submit();
 
    //set it back to the original one
    $('form').attr('action', originalUrl).removeAttr('target');
 
    //change the ViewState value back to what it was
    $('#__VIEWSTATE').attr('name', '__VIEWSTATE');
 
});
