i often use this notation when i name my controls in order to get an array in POST or GET.

<input name=color[1] type=text />

<input name=color[2] type=text />

<input name=color[3] type=text />

so in my scripts i can do

<?php $data=$_GET[color]; 

for each ($color as $key=>$value) {

   doSomething();

} ?>

Often happens that i need to get those id back in javascript , but i cannot get them , so i often add an ID to each element in html like that

<input name=color[3] id=color_3 type=text />

so that i can use document.getElementsById('color_3')

Instead i would like to find way to use document.getElementsByName(color[3])...
but i cannot really get it to work.

Any help?

<input name=color[3] id=color_3 type=text />



var element = document.getElementsByName(color[3]);



alert(element[0].id);

It works fine .. The thing you should have in your mind is Return type is an array of elements not a single element
