Possible Duplicate:
use brackets in checkbox name when using php and javascript?

I use as name of input field in html code :

<input size="15" name="user[135][name]" value="" disabled=disabled>

then I want to work with it in javascript like this: 

if(some_condition)  { document.myform.user[135][name].disabled=false; }

But that doesn’t work, because of the brackets in field name. Is there any way how to solve it without changing html code?

Experience: if I use name as user_135_name all works perfectly.

thankx for help.

    I’ll suggest add id to your input tag as follows

    <input size="15" id="user_name_135" name="user[135][name]" value="" disabled=disabled>

    Using simple Javascript

    if(some_condition) { document.getElementById("user_name_135").disabled=false; }

    Using jQuery

    if(some_condition){ $("#user_name_135").prop('disabled', false);}

    Also if there is only one statement followed by if you can omit {}

    if(some_condition) 
  document.getElementById("user_name_135").disabled=false;

    Edited
    Please save following code as a html file and see it should work for you

    <!doctype html>
<html>
<head>
<script>
function some(){
  document.getElementById("user_name_135").disabled=false;
}
</script>
</head>
<body>
<input size="15" id="user_name_135" name="user[135][name]" value="" disabled=disabled>
<a href ="javascript:void(0)" onclick="some()">disbale input</a>
</body>
</html>
