Option: onpageload

This option enables you to specify a function name to be executed when the page is loaded but before the TinyMCE instances are created.

Example of usage of the onpageload option:

function myCustomOnPageLoad() {
	alert("We are nearly ready to rumble!!");
}

tinyMCE.init({
	...
	onpageload : "myCustomOnPageLoad"
});
