    //var val = $("#FieldId").val()
//Get Value of hidden field by val() jquery function I'm using example string.
var val = "String to find after - DEMO"
var foundString = val.substr(val.indexOf(' - ')+3,)
console.log(foundString);
    Assuming you need to find DEMO string after - by above code you can able to access DEMO string substr will return the string from whaterver the value indexOf return till the end of string it will return everything.

    You can use .indexOf() and .substr() like this:

    var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

    You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

    var myString = $("input").val().split("?").pop();

    Here's a way:

    <html>
    <head>
        <script src="jquery-1.4.2.min.js" type="text/javascript"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                var value = $('input[type="hidden"]')[0].value;
                alert(value.split(/\?/)[1]);
            });
        </script>
    </head>
    <body>
        <input type="hidden" value="/TEST/Name?3" />
    </body>
</html>

    Assuming you have your hidden input in a jQuery object $myHidden, you then use JavaScript (not jQuery) to get the part after ?:

    var myVal = $myHidden.val ();
var tmp = myVal.substr ( myVal.indexOf ( '?' ) + 1 ); // tmp now contains whatever is after ?
