Show selected values from listbox

Recommended Posts

Use the code below :


var field= "InsertRecordFIELDNAME"; 
   var x=document.getElementsByName(field);

document.getElementById("Submit").onmouseover= function(){
var l = document.getElementById(field); 

for (var i = 0; i <  l.options.length; i++) {
     if(l.options[i].selected == true){

      var   o = o + "," +l.options[i].value; 
document.getElementById('cbParamVirtual1').value = o.substring('undefined,'.length);


in "InsertRecordFIELDNAME" replace  FIELDNAME to the listbox field name. And also "cbParamVirtual1" is the ID of Virtual 1. This code will trigger on hovering over submit button. 


To fire the code when selection is done you can change

Hi @Master,

As of July 12, 2018, Caspio introduced new features which you can find here: https://howto.caspio.com/release-notes/caspio-bridge-13-0/

This release includes a new feature, Calculated Values in Submission Forms.  You can use this to your Virtual Field to get the value of your Listbox. 

Check these videos for more information:


I hope this helps!
