Checking querystring for a not null value using JS
<p>Is it possible to check a querystring for a not null value using javascript? Can you show me an example on how to do this?</p>

<p>Like the IF clause of this snippet:</p>

<pre><code> protected void Page_Load(object sender, EventArgs e)
    {
        if (!string.IsNullOrEmpty(Request.QueryString["someParameter"]))
        {
            DataListWithLinksID.Attributes.Add("style", "display:none");
        }
    }
</code></pre>
