<script language="javascript">
function toggle(id) {
alert('call');
if (document.getElementById(id).style.display == "none") {
alert('now visible');
document.getElementById(id).style.display = "";
} else {
alert('now invisible');
document.getElementById(id).style.display = "none";
}
}
</script>
</head>
<body onload="toggle('image1');alert('test_body');toggle('image2')">
<script language="javascript">
alert('test_pre_function');
toggle('image1');
alert('test_after_function');
toggle('image2');
</script>
Looks like a lot of code but it's pretty simple so i think most of you won't have troubles with it. toggle() should toggle the display status of divs containing images.
When the user enters the site the divs should hide, when everything is loaded the divs should show up. (onload)
Strangely enough, the funtion in the body (not in the body tag) only work half, i get and alert 'test_pre_function' and i get an alert 'call' (out of the function), but that's it. The code in the body tag runs just fine.
I find this weird because it's supposed to do exactly the same twice and one time it runs, another time not, so i guess i must have made some stupid mistake.
Thanks for any help!
