Run script onload and onchange?

[mdav20]

I have the following script for onchange...  I would like run it onload also, is there a easy way to do it?

 

 

<SCRIPT LANGUAGE="JavaScript">

 function calculate()
 {
var current = parseFloat(document.getElementById("cbParamVirtual1").value);
if (isNaN(current)) current = 0;
var installed ='[@calcfield:2]';
var total_hrs ='[@calcfield:1]';

var currenttotal = parseFloat((current - installed) + parseFloat(total_hrs));

document.getElementById("cbParamVirtual2").value =Math.max(0, currenttotal);

}

document.getElementById("details").onchange=calculate;

</SCRIPT>

Thanks in advance!

Hello mdav20,

I would suggest creating the separate function, so you could call this function with a different event "onload".

Hope this helps.
