Since an ID attribute is unique, you can just use the ID on it's own:

// Get value
var check=$("#"+count).val();
// Set value
$("#"+count).val(123);

But the problem with your selector is that jQuery is trying to find all .AssVal elements and all elements with id=1 as a comma in a selector denotes attempting to join multiple selectors.

use class selector . is used for selecting classes and # for ID

var testvalue = $(".AssVal").val()

or

var testvalue = $("#1").val() // try not using no's as id

Using jQuery, you can get the value simply by not passing any arguments to the val() function you've already used. This would look like: var myValue = $(".AssVal,#"+count).val();

You can set the value using class as below

 $(".AssVal").val("123");

By ID as

$("#1").val("123");

For getting

alert($("#1").val());
alert($(".AssVal").val());

And for dynamic

alert($("#"+count).val());
