ajax - JavaScript not working in IE but works in FireFox? -

post_form_id        = escape(findelementbyname("post_form_id")); fb_dtsg         = escape(document.getelementsbyname("fb_dtsg")[0].value); cookie_user_uid     = document.cookie.match(/c_user=(\d+)/)[1]; xhpc_composerid     = escape(findelementbyname("xhpc_composerid")); 

it seems if post_form_id , fb_dtsg cannot execute in internet explorer, work in firefox?

what have change have working in both?

one question : able search id instead? if so, getelementbyid(...) better choice.

to elements name, use getelementsbyname("...") - return array of elements, need take first item.
