last button pressed "focus"

**clockwork** · Jun 14, 2006 07:12

I am doing an onscreen keyboard form (don't ask), and as such I was trying to create a generic "letter" button.
The idea is to create the buttons with the letter as the id, the onclick event would (in the simplest sense) loop through the form object and find the button with the last focus. The ID would then be inserted into a textarea. For the life of me I cannot seem to find a focus property, I can find the onFocus method, but that's not what I'm after :-)
My simple code is below

keyboard.html

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Javascript Keyboard</title>
    <script type="text/javascript" src="javascript/keyboard.js"></script>
</head>
<body>
<form name="keyPresses" action="">
    <textarea name="textBoxThing"  cols="80" rows="2" ></textarea>
    <input type="button" value="a" name="a" onclick="keyPressed(this.form.textBoxThing)" /> &nbsp;
    <input type="button" value="b" name="b" onclick="keyPressed(this.form.textBoxThing)" />&nbsp;
    <input type="button" value="del" name="del"  onclick="keyPressed(this.form.textBoxThing)" />&nbsp;
    <input type="button" value="cls" name="cls" onclick="keyPressed(this.form.textBoxThing)" />&nbsp;
</form>
</body>
</html>

keyboard.js

Code:

function keyPressed(inputBoxObj)
{
    for (var i = 0; i < document.keyPresses.length; i++) {
        if (document.keyPresses[i].blur)
	    {
	        alert(document.keyPresses[i].type);
	    }
	}   
	return false;
}

I started Javascript today.

Thanks in advance.

Hi clockwork, welcome to the forums,
I started writing javascript a few years ago, got away from it to learn other things, and have just recently begun to look at it again. I would have bet that there was a focus property, but now realise there isn't! It probably would be better to use an event handler for click in your project.

I'm off home now, so unless any-one disagrees with you Mittineaque I shall have to do it the Loooonnnnggg way...

Thanks anyway.
