May 17, 2005 at 5:15PM The DOM HTMLFormElement Interface Should Have a getElementsByName() Method
While useful on the HTMLDocument interface, getElementsByName() would be much more useful if it was included in HTMLFormElement interface. Every time I want to look up elements by their names, it’s usually on form elements rather than the document as a whole. Come to think of it, I don’t think there’s ever been a time I wanted to look elements up by name on the document, whereas I’ve wanted to do it on forms quite a bit. What a pain.
Oh, and here’s some code to get the same effect.
function GetElementsByName(frm, name) { var elements = []; for (var i = 0; i < frm.elements.length; i++) { if (frm.elements[i].name == name) { elements[elements.length] = frm.elements[i]; } } return elements; }
It’s trivial, but hey!

form.elements[name]orform[name]will return a filtered collection of all form elements with the matching name.2 On June 2, 2005 at 15:35, Keith wrote:
Really? I thought the subscript as restricted to numbers.

Jimmy, you’re right. I’d something that required me to do this, so I tried it to check if you were right, and it works.
Thanks for the correction.

But Jimmy forgot to mention the fact that
document.forms[my_form].elementswill ignore elements that have been dynamically added to the form via DOM manipulation.
