How to select specific form element in jQuery?

I have two form like this:

<form id='form1' name='form1'>
  <input name='name' id='name'>
  <input name='name2' id='name2'>
</form>

<form id='form2' name='form2'>
  <input name='name' id='name'>
  <input name='name2' id='name2'>
</form>

Now I want to insert text in name field of form2. I am using following jQuery code but it fill name field of form1.

$("#name").val('Hello World!');

So how to select specific form elements only?

It isn't valid to have the same ID twice, that's why #name only finds the first one.

You can try:

$("#form2 input").val('Hello World!');

Or,

$("#form2 input[name=name]").val('Hello World!');

If you're stuck with an invalid page and want to select all #names, you can use the attribute selector on the id:

$("input[id=name]").val('Hello World!');
