I have attached codes in html/javascript.
How can I load both hidden value to Onload event in Javascript.
Assume both hidden fields already have value there .

Thank

Gregg

Are you trying to set the value of the hidden form fields? And run the initialize function during the window onload event? If so please see attached sample.

You will need to uncomment the initialize function and delete the alert. Hope this helps.

addEvent(window, "load", function() {
	//Set To Address
	var from = document.getElementById("fromaddress");
	from.value="100 Main Street. Los Angeles, CA 90032";
	
	//Set From Address
	var to = document.getElementById("toaddress")
	to.value="200 Main Street. Los Angeles, CA 90032";
	
	//initialize method call.
	//initialize(from,to);
	
	alert(to.value);
});
