Hi Samuel, IE 11 is not supporting startsWith(). As a workaround goto <cfusion_home>\wwwroot\cf_scripts\scripts\ajax\package\ and add the following snippet to cfajax.js if (!String.prototype.startsWith) { Object.defineProperty(String.prototype, 'startsWith', { value: function(search, pos) { pos = !pos || pos < 0 ? 0 : +pos; return this.substring(pos, pos + search.length) === search; } }); } Thanks, Manas

It appears this block did not get added to the official code base and you will have to manually add it after updating to hotfix 9 and 10 as well.

Yes Samuel absolutely correct. IE is expected to support this in its next releases. Closing this thread for now. Do let us know if you face any other issues. Thanks, Manas

Can anyone provide some insight as to where exactly the code above should be added into the cfajax.js file? What line number should it be added to? Is there any existing code in the cfajax.js file that needs to be commented out in order to get this to work?
