jQuery selector by form index and input name

Question

Take the following page with two forms with different classes but each form has an input with the same name.

<form class='first_form'>
 <input name='test' value='1' />
</form>
<form class='second_form'>
 <input name='test' value='3'/>
</form>

I can get the form index and I know the name of the input but I do not know the index of the input.

Is there a way to chain a selector with the form index and the input name to get the value?

I have tried chaining but nothing seems to work

var inputName = 'test';
Var formIndex = 1;

$('*[name="' + inputName + '"]' +' ' + '$("form").eq(' + formIndex + ')').val();

Answer 1

FIDDLE

var formIndex=0;
var inputName="txtbox";
vall= $("form:eq("+ formIndex+") input[name= "+ inputName +" ]").val();
alert(vall);

your order was wrong

Answer 2

Untested, but could you do:

$('form:nth-of-type(1) input[name="test"]').val();
