Code to force a cascading element to update

Recommended Posts

Hello all,

Im using the following code to combine the values of several fields to create a parent value for a cascading element.  My problem is the cascading elect won't update unless I actually type in the parent field - how can I force the cascade to update?

document.getElementsByName("InsertRecordFrame_Desc")[0].onchange = function () {{

var box80 = document.getElementsByName("InsertRecordFrame_Collection")[0];

var box81 = document.getElementsByName("InsertRecordLens_Package")[0];
var box82 = document.getElementsByName("InsertRecordInsuranceLevel")[0];
var box83 = document.getElementsByName("InsertRecordInsuranceDet")[0];

box83.value = box82.value + box80.value + box81.value;

Hi @braxwell

You can try using this example:


Virtual4 is dependent on Virtual3. Type in Apple + Pie separately on Virtual1 and Virtual2

document.getElementsByClassName("cbFormTextField")[0].addEventListener("change", function(){

var v1 = document.getElementsByName("cbParamVirtual1")[0];
var v2 = document.getElementsByName("cbParamVirtual2")[0];
var v3 = document.getElementsByName("cbParamVirtual3")[0];

v3.value = v1.value + v2.value;

var event = new Event('change');



I have used 

var event = new Event('change');

to trigger a change to make the cascade update. You may modify it to fit your needs.
