Using getElementsByName without starting at document root

Question

Is there a way to use getElementsByName without starting from the DOM root.

For example I have a div element, and want to start searching from that element.

If not, then do I have to write my own function that recursively iterates through the child nodes, or is there a different way to do it.

Answer 1

getElementsByName and getElementById are both members of the document object, and aren't part of the HTMLElement prototype. In modern browsers (IE8, Firefox, Chrome, Opera), you can use element.querySelectorAll("*[name='myName']").

Other than that your alternative is to use a library like Sizzle or a framework such as jQuery (which uses Sizzle) to handle selectors.
