I'm trying to remove the id from all <td> that are named "date[]", because if i keep the id, a jquery datepicker messes up later.

the following function is used to remove the id

document.getElementsByName('date[]').removeAttribute('id');

Firebug tells me: TypeError: document.getElementsByName(...).removeAttribute is not a function

I tried all combinations of ' and ", and also just date instead of date[]. I don't think its a typo, because i copied this from w3schools

    does document.getElementsByName('date[]') return a collection of DOM nodes? Commented Jan 22, 2015 at 19:16

document.getElementsByName returns a collection, you have to iterate and remove:

var collection = document.getElementsByName('date[]'); for (var i = 0; i < collection.length; i++) { collection[i].removeAttribute('id'); }
