Loading Total On Form Load

Post a Comment
Hi I have following input which gets values and calls function fntotal to display total. The code works fine when values are changed. However when values are loaded in the form it

Solution 1:

Set an onLoad event listener to the <body> tag.

Solution 2:

I think following code will do, it is combination of jquery & javascript

$(document).ready(function(){
  var formObj = document.getElementById('<form_id>');
  fntotal(formObj);
});

You have to include jquery lib if you have not included it first.

To do that put following in begining of your tag.

<scriptsrc="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
