jQuery replacement of Prototype method
<p>I have the following script which will change the background image of a text box on focus and retain the previous image ob blur, if the content is emapty.The images are something like watermarks.This is making use of prototype javascript library.</p>

<pre><code>  &lt;div class="searchfield"&gt;
                &lt;asp:TextBox ID="txtStoreId" runat="server" class="username searchbg"&gt;&lt;/asp:TextBox&gt;

                &lt;script type="text/javascript"&gt;
//&lt;![CDATA[
var storeidLabel = new FormLabel('txtStoreId', {image:'../lib/images/store_id.gif', emptyImage:'../lib/images/bg_userpw_notext.gif'});
//]]&gt;
&lt;/script&gt;

  &lt;/div&gt;
</code></pre>

<p>Now i want to have the jQuery replacement of this.I am already using jQuery in my page.I want to take the prototype away from my page.</p>
