Javascript help needed

Recommended Posts

Can someone help with this javascript please...I'm using a submission form and one of the fields in the calculation is a cascading dropdown with  a parent of Merchandise_ID and the other is a text input field.  Not sure why its not working, but nothing is showing up in the destination field.


<strong><span style="color:#000000;"></span></strong>
<strong><span style="color:#000000;">
<div id="mypage1">

 function calculate()
 var Gross_Qty_Sold = isNaN((parseFloat(document.getElementById("InsertRecordGross_Qty_Sold").value)))?0:(parseFloat(document.getElementById("InsertRecordGross_Qty_Sold").value));

   var Merchandise_Cost = isNaN((parseFloat(document.getElementsByName("InsertRecordMerchandise_ID_Merchandise_Cost")[0].value)))?0:(parseFloat(document.getElementsByName("InsertRecordMerchandise_ID_Merchandise_Cost")[0].value));

     var total= (Gross_Qty_Sold * Merchandise_Cost);

document.getElementById("mypage1").innerHTML=' $'+total ;
document.getElementById("InsertRecordGross_COGS").value=total.toFixed(2) ;

If I understand correctly, you use Cascading Field as a trigger for calculation?


If yes, then I am afraid It is not possible.

Perhaps, it is possible for .onsubmit action. ( Not sure).
