I have an footer.php file that have javascript code and functions. I use this footer.php file for all of my pages. When clicking buttons I use
onclick="MyFunc()"
but in some pages I need to call MyFunc without onclick, just when page loaded. I can not use "body onload" function because the tag is in header.php file that all pages is using it. I have triend to put
<script Language="JavaScript">
window.onload=MyFunc;
</script>
in my php file and
<script Language="JavaScript">
function MyFunc(){
alert('hello');
}
</script>
in the footer.php but with no luck.

if you dont have problem with jquery, then you can use
$('document').load(/*your function*/). – schnill Commented Aug 19, 2013 at 12:53 - why you are not using jquery ?? $('document').ready() – Prince Singh Commented Aug 19, 2013 at 12:54

You could use jquery library and then
$(window).load(function () { MyFunc(); });– Shuhel Ahmed Commented Aug 19, 2013 at 12:55

Reset to default 1"but in some pages I need to call MyFunc without onclick"
What I understand from your question is:
- You want to fire
MyFuncon a few pages - All pages include
footer.php(at the end, I assume). MyFuncis already present
If that's right, you'll have to trigger this event somehow only on the pages that you want it to fire. This can be done two ways.
Add a small snippet to the automatically firing pages
window.addEventListener('load', MyFunc, false);
This code will add the MyFunc function to the array that will be fired when the page is laded. Remember: window.onload and this will fire after all images have been loaded.
Trigger MyFunc automatically
I don't know what the difference between those pages is, but this could be done by firing the function when the page is loaded, just like the snippet I showed above, and just before this is done you check for a trigger. For example, if your page where it fires has an element with a specific class test, simply check if it exists (document.getElementsByClassName('test').length > 0) and then fire MyFunc.
I hope this helps.
if its in the footer (end of the page) you can simply enter this code where you need
<script>
MyFunc()
</script>
this will call the function
as I know the language attribute is obsolete
try to use <script type="text/javascript"> instead of <script Language="JavaScript">
EDIT: put a sample to here jsFiddle
As stated you could use window.onload or you could attach the event to DOM load
<body onload="MyFunc()"></body>
