Hi i have string value of <input type="hidden" name="SaleDetail[7835].ProductID" value=7835 /><input type="hidden" name="SaleDetail.Index" value="7835" />

but when I run below to extract value from input, it just returns undefined ..

var stringVal = '<input type="hidden" name="SaleDetail[7835].ProductID" value=7835 /><input type="hidden" name="SaleDetail.Index" value="7835" />'
var inputVal = $('input[name="SaleDetail.Index"]', $(stringVal)).val();

Can anyone help ?

Your code would search for nested children element since there are no nested children it won't return any element. To get the element from a collection of element use filter() method instead.

var stringVal = '<input type="hidden" name="SaleDetail[7835].ProductID" value=7835 /><input type="hidden" name="SaleDetail.Index" value="7835" />'
var inputVal = $(stringVal).filter('input[name="SaleDetail.Index"]').val();

console.log(inputVal);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Or you need to wrap the elements by any other element to make it work.

var stringVal = '<input type="hidden" name="SaleDetail[7835].ProductID" value=7835 /><input type="hidden" name="SaleDetail.Index" value="7835" />'
var inputVal = $('input[name="SaleDetail.Index"]', '<div>' + stringVal + '</div>').val();

console.log(inputVal);
