How to get query string value in javascript

 

Hi Friends,

Few days ago I need to get the query string value at client side in my application then I got a java script method via searching which returns the query string value.

You just pass the name of the parameter name to the method. Here I am placing the method.

<script type="text/javascript">
function getQuerystring(key, default_) {
        if (default_ == null) default_ = "";
        key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
        var regex = new RegExp("[\\?&]" + key + "=([^&#]*)");
        var qs = regex.exec(window.location.href);
        if (qs == null)
            return default_;
        else
            return qs[1];
    }
</script>


you just get the query string value like this 
var paraValue=getQuerystring(key, 'ParaName') ;

Hope this will help you...
