inquiry about javascript code

this dude is helping me trouble shoot this javascript code in order to help get a 'mouseover' sound effect to work on all 3 major browsers.

All he basically added was this code to the .js file , to get it to work... along with commenting out a couple lines of the original code.

since i'm not a js expert, was just wondering if any of this could be a security issue ? I've only asked for help from the guy a couple times.


function getElementsByTagNames(list,obj) {
 if (!obj) var obj = document;
 var tagNames = list.split(',');
 var resultArray = new Array();
 for (var i=0;i<tagNames.length;i++) {
 var tags = obj.getElementsByTagName(tagNames[i]);
 for (var j=0;j<tags.length;j++) {
 resultArray.push(tags[j]);
 }
 }
 var testNode = resultArray[0];
 if (!testNode) return [];
 if (testNode.sourceIndex) {
 resultArray.sort(function (a,b) {
 return a.sourceIndex - b.sourceIndex;
 });
 }
 else if (testNode.compareDocumentPosition) {
 resultArray.sort(function (a,b) {
 return 3 - (a.compareDocumentPosition(b) & 6);
 });
 }
 return resultArray;
}

thanks much
