How can I call a JavaScript function on page load without making
<body onload='callFunction()'>
i want to check when loading the page what is the purpose of using that page, if for addition then ok , if for edition , there will be data come from server to be displayed in that page, so i want to check the request each time page is loaded , since i don't have body tag in my page cz i use jspf (JSP Fragment) . NOTE : i don't know jQuerry , is there's another way?
window.onload = yourfunction;
Or with jQuery if you want:
$(function(){
yourfunction;
});
If you want to call more than one function on page load, take a look at this article for more information:
Your original question was unclear, assuming Kevin's edit/interpretation is correct then this first option doesn't apply
The typical options is using the onload event:
<body onload="javascript:SomeFunction()">
....
You can also place your javascript at the very end of the body; it won't start executing until the doc is complete.
<body>
...
<script type="text/javascript">
SomeFunction();
</script>
</body>
And, another options, is to consider using a JS framework which intrinsically does this:
// jQuery
$(document).ready( function () {
SomeFunction();
}
If you want the onload method to take parameters, you can do something similar to this:
window.onload = function()
{
yourFunction(param1, param2);
};
This binds onload to an anonymous function, that when invoked, will run your desired function, with whatever parameters you give it. And, of course, you can run more than one function from inside the anonymous function.
