Get button name inside javascript function
<p>I have a html button with runat=server tag, whoose Name has been set dynamically during run time.</p>

<pre><code>    protected void Page_Load(object sender, EventArgs e)
    {
        btnShowHideCols.Name = "some text here";
    }
</code></pre>

<p>the button HTML code is like below.</p>

<pre><code>    &lt;input id="btnShowHideCols" type="button" value="+/-" runat="server" onclick="return btnShowHideCols_onclick()" /&gt;
</code></pre>

<p>How Do I get the button name form inside the javascript function? can I get the sender of the event there?</p>
