Passing and Retrieving Querystring using JavaScript in ASP.NET

 Hi ,

We all are familiar with Query string in asp.net.Today I'm showing query string handling with JavaScript .

To sent the data to another page i create a function on page1.aspx and call the function on client-side button click

    <script type="text/javascript" language="javascript">
        function PassQuery()// my fuction
        {
            var paramVal1 = "SimplyAsp.net";
            var paramVal2 = "simplyasp.blogspot.com";
            window.open("Page2.aspx?id=" + paramVal1 + "&p=" + paramVal2);
        }
    </script>

To retrieve the value i call another function on body load of page2.aspx

    <script language="javascript" type="text/javascript">
        function GetQueryValue()
        {
           
                var query = window.location.search.substring(1);
                var parms = query.split('&');
                for (var i = 0; i < parms.length; i++) {
                    var pos = parms[i].indexOf('=');
                    if (pos > 0) {
                        var key = parms[i].substring(0, pos);
                        var val = parms[i].substring(pos + 1);
                        alert(val);
                    }
                }

        }
    </script>
