how to reference Calculated Virtual Field Value in Javascript

Recommended Posts

Please bear with me as i try to unfold this.

I have a submission datapage with a Virtual Field  (Virtual23) where as a Calculated Field i'm using a SELECT statement to fetch what I need correctly.  This is successful.

Where i'm struggling is how to reference this value in javascript.   I'm trying to store the value in a varable ...

I've tried this: 

var  x = document.getElementById("cbParamVirtual23").value;

and it doesn't seem to work.  I'm assuming the value fetched by the SELECT statement should return a string.

I've tried the below code to test if it works, but it fails. 

document.getElementById("ElderbergHTMLBlock1").innerHTML = x;
document.getElementById("ElderbergHTMLBlock1").innerHTML = x.toString();

Solution Involves 2 Parts:

Part 1:  You need to use setTimeout() method to delay the code such that it runs AFTER the calculated fields get computed.  See https://www.w3schools.com/jsref/met_win_settimeout.asp 


Part 2:  You need to reference calculated fields using the document.getElementsByName with index 0  instead of by ID, this is because caspio adds some alphanumeric codes after the Virtual Parameters ID when its set to a Calculated Field.

See Code:
var x = document.getElementsByName("cbParamVirtual27")[0].value;
document.getElementById("ElderbergHTMLBlock1").innerHTML = x;
