BetterInnerHTML

/ Published in: JavaScript

This is optimized code. I absolutely love that it validates the html and allows you to simply append to instead of having to capture and rewrite. Very handy on many projects!

Highlighted TextExpand

function BetterInnerHTML(o,p,q){function r(a){var b;if(typeof DOMParser!="undefined")b=(new DOMParser()).parseFromString(a,"application/xml");else{var c=["MSXML2.DOMDocument","MSXML.DOMDocument","Microsoft.XMLDOM"];for(var i=0;i<c.length&&!b;i++){try{b=new ActiveXObject(c[i]);b.loadXML(a)}catch(e){}}}return b}function s(a,b,c){a[b]=function(){return eval(c)}}function t(b,c,d){if(typeof d=="undefined")d=1;if(d>1){if(c.nodeType==1){var e=document.createElement(c.nodeName);var f={};for(var a=0,g=c.attributes.length;a<g;a++){var h=c.attributes[a].name,k=c.attributes[a].value,l=(h.substr(0,2)=="on");if(l)f[h]=k;else{switch(h){case"class":e.className=k;break;case"for":e.htmlFor=k;break;default:e.setAttribute(h,k)}}}b=b.appendChild(e);for(l in f)s(b,l,f[l])}else if(c.nodeType==3){var m=(c.nodeValue?c.nodeValue:"");var n=m.replace(/^\s*|\s*$/g,"");if(n.length<7||(n.indexOf("")!=(n.length-3)))b.appendChild(document.createTextNode(m))}}for(var i=0,j=c.childNodes.length;i<j;i++)t(b,c.childNodes[i],d+1)}p="<root>"+p+"</root>";var u=r(p);if(o&&u){if(q!=false)while(o.lastChild)o.removeChild(o.lastChild);t(o,u.documentElement)}}
