Can i find out which control has the focus?

Copy linkTweet thisAlerts:

I have a Javascript function that runs on the KeyDown event of a page, i need to be able to determine which control on my form had/has the focus at the time the function executes, is this possible in Javascript?

Its not really appropriate that i bind the function to all the controls on the page/form, it kinda has to run on the KeyDown event of the page itself, but i ant seem to find a way to identify which control had the focus when a key was pressed…

Can anyone help or point me in the right direction?

Thanks in Advance

&lt;head&gt;
&lt;script type="text/javascript"&gt;
&lt;!--
document.onkeydown = new Function("window.status = [color=red]event.srcElement.id[/color];");
//--&gt;
&lt;/script&gt;
&lt;/head&gt;
&lt;body id="body"&gt;
&lt;form id="form1"&gt;
&lt;p&gt;&lt;input type="text" id="text1" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;input type="text" id="text2" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;input type="text" id="text3" /&gt;&lt;/p&gt;
&lt;p&gt;&lt;input type="button" value="Button" id="button1" /&gt;&lt;/p&gt;
&lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;

As delineated by the red text, the [FONT=courier new]event.srcElement[/FONT] piece is the key. I'm assuming that the elements [FONT=courier new]id[/FONT] would probably be the most useful property for differentiating between the form controls. I hope that's what you were looking for!
