How to find Out the Parameter value from the Query String in the URL?

Here is the Code to do this-

function GetParameterValues(param) {

    var url = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');

    for (var i = 0; i < url.length; i++) {

        var urlparam = url[i].split('=');

        if (urlparam[0].toLowerCase() == param.toLowerCase()) {

            return urlparam[1];

        }

    }

}

Use:

<script>

 var name = GetParameterValues('name');

var id = GetParameterValues('ID');

alert("Hello " + name + " your ID is " + id);

</script>
