    Changing a Div's background image onMouseOver

    I'm sure this is a very simple script but I have very little experience in JavaScript. I am trying to learn it and I would appreciate it if you help me create this effect .

    Style.css
    Code:
    #test{
       background-image:url(images/bg1.gif);
       height:100px;
       width:100px;
    }
    and I imagine the HTML would look something like this, with the Javascript I have so far.

    Code:
    <html>
    ...
    <script type="text/Javascript">
    function changeBgImage (image , id) {
    var element = getDocumentByID(id);
    element.style.background-image = url(image);
    }
    </script>
    
    <body>
    
    <div id="test" onMouseOver="changeBgImage('images/bg2.gif','test')">
    </div>
    
    </body>
    </html>
    That's basically it. Any help is appreciated.

    	element.style.backgroundImage = "url("+image+")";
    }
    </script>

    <body>
    <div id="test" onMouseOver="changeBgImage('images/bg2.gif', 'test')">

    What about on a Mouse Exit?

    What additional script needs to be included to have it return to the original image on a mouse exit?

    Hey guys, could the above snippet be modified to work onClick and with multiple background images on one div? Ideally the background change would depend on which of a series of links was clicked.

    Code:
    <div 
        id="test" 
        onMouseOver="changeBgImage('images/bg2.gif', 'test')"
        onMouseOut="changeBgImage('images/bg1.gif', 'test')">
    </div>

    this code does not account for the right side of the div tag. onmouseout works for the top left and bottom sides but not the right ideas?

    Can someone tell me with using the same method, how can you remove the image as you use "onMouseOut"??

    Thumbs up more simple

    this code functions very well to change the background image

    <center class="menu" onmouseover="this.style.backgroundImage='url(images/image_2.jpg)'" onmouseout="this.style.backgroundImage='url(images/image_1.jpg)'">

    in the css the bg image must be set how 'image_1.jpg', so whem you goes with the cursor on this, it change to 'image_2'.. with the cursos goes out, it come back to 'image_1'

    very simple
