js根据属性查找元素代码

functiongetElementByAttribute(aAttribute,aValue,aInElement)
...{
varElementVerifier;
varElements=newArray();
functionSearchElement(aElement)
...{
if(aElement==null||aElement==undefined)return
if(ElementVerifier(aElement))
...{
Elements[Elements.length]=aElement;
}
SearchElement(aElement.firstChild);
SearchElement(aElement.nextSibling);
}

if(aInElement==undefined)aInElement=document.body;

ElementVerifier=function(aElement)
...{
Element=aElement;
if(aElement.nodeName=='#text')returnfalse;
functionmyEqual(Element,aValue)...{
vareq=false;
if(!(eq=(Element.getAttribute(aAttribute)==aValue)))
...{
eval('try{eq=(Element.'+aAttribute+'=="'+aValue+'");}catch(e){}');
}
returneq;
}
returnmyEqual(Element,aValue);
}
SearchElement(aInElement);
returnElements;
}

似乎查找的效率有点低
