Changing input name attribute

Question

Hello! I have some hidden inputs like this

<input name="exam.normals[1].blahblah" ..../>

I would like somehow to replace the [1] with a number that I want (index).

I aint lazy but I am trying to find a good way to do this...

A solution would be a replace of exam.normals[1] with exam.normals[+ index +] but I should substr the whole string first.... With regexp I don’t know how to do the replace. good...

Answer 1

You can do this:

$("input[name*='[1]']").attr('name', function(i, v) {
  return v.replace('[1]', '[' + i + ']');
});

This finds inputs that have a name with [1] in them, then replaces [1] with [0] on the first [1] on the second, etc.

Answer 2

Try something like this:

$("input[name]").each(function() {
    var $this = $(this);
    $this.attr("name", $this.attr("name").match(/\[\d+]/g, "["+index+"]"));
});
