JS code check for browser compatibility

[pankajit09]

Please tell me whether the below JS code will run in all the browsers -->

function getHTML(num) {
        var saf = 0 ;
        var num;
        if(!num) {
            num = document.getElementById('refid').value;
        } else {
            num = num;
        }
	    var url = '/cgi-bin/ptts/search.cgi';
		var pars = 'num='+num+'&showallfiles='+saf+'&act=showattachedfilesection';
        var myAjax = new Ajax.Updater( {success: 'placeholder'}, url, { method: 'get', parameters: pars, onFailure: reportError });
    }

Everything looks fine but you haven't included the code behind your Ajax object. If you post that perhaps someone will be able to tell you.

Is it mandatory that the data returned by the Perl script should be in XML format as Ajax transactions are through XML ?

Not necessary. It depends on how you parse/deal with it on the client-side. See a non-XML server response example here.
