Replacement of .all() function for Browsers other

问题:

I am using following code

myEl = document.createElement("myElement") ;
//in a loop
myEl.innerHTML = myEl.innerHTML + currElement.outerHTML ; //some elements getting added to it
var newElement = myEl.all(idToSearch) ;

the last line is not working for browsers other than IE.. I am particularly using Chrome, is there any alternative for it???

回答1:

You can use querySelector() on elements that aren't yet attached to the document:

var newElement = myEl.querySelector("#" + idToSearch);

回答2:

all is a proprietary IE extension totally unsupported by standards compliant browsers.

Use document.getElementById() or start looking at libraries like jquery (which would also help with the innerHTML problems you're likely to encounter).
