Find All Elements By Class

to html javascript dom by bitshaker on Sep 18, 2006
// Javascript function that will return an array of elements based on DOM element, tag, and class name.
// For instance, getElementsByClassName(document, 'tr', 'INFO') will get all "tr" tags under the document node with the "INFO" class and return an array of them.

function getElementsByClassName(oElm, strTagName, strClassName){
var arrElements = (strTagName == "*" && document.all)? document.all : oElm.getElementsByTagName(strTagName);
	    var arrReturnElements = new Array();
	    strClassName = strClassName.replace(/\-/g, "\\-");
	    var oRegExp = new RegExp("(^|\\s)" + strClassName + "(\\s|$)");
	    var oElement;
	    for(var i=0; i<arrElements.length; i++){
	        oElement = arrElements[i];
	        if(oRegExp.test(oElement.className)){
	            arrReturnElements.push(oElement);
	        }
	    }
	    return (arrReturnElements)
	}
