JavaScript - Add Value from Virtual Field

Recommended Posts


I am attempting to create an option on a submission form that will allow me to add a value to a dropdown list of values if that particular value is not currently in the dropdown. I know that you can do this via:


But it resets all the values and the flow is not ideal. I have 3 dropdowns that each have "add new" virtual field checkbox. So if the value is not in the dropbox, I would click the corresponding "Add New" and then type out the new value. (see the id's for each via picture)

Here is my current code:
- Placed in footer (though I tried in HTML block placed last on the form, as well)

<script type="text/javascript">
function d_text()


document.getElementById("cbParamVirtual1").disabled = true;

document.getElementById("cbParamVirtual3").disabled = true;

document.getElementById("cbParamVirtual5").disabled = true;


function f_boxcheck()



document.getElementById("cbParamVirtual1").disabled = false;

}else {document.getElementById("cbParamVirtual1").disabled = true;}


function s_boxcheck()



document.getElementById("cbParamVirtual3").disabled = false;

}else {document.getElementById("cbParamVirtual3").disabled = true;}


function r_boxcheck()



document.getElementById("cbParamVirtual5").disabled = false;

}else {document.getElementById("cbParamVirtual5").disabled = true;}


function transfer()




document.getElementById("InsertRecordCategory_ID").value = document.getElementById("cbParamVirtual1").value;




document.getElementById("InsertRecordSub_Cat_ID").value = document.getElementById("cbParamVirtual3").value;




document.getElementById("InsertRecordDiv_Cat_ID").value = document.getElementById("cbParamVirtual5").value;



window.onload = d_text;
document.getElementById("cbParamVirtual2").onclick = f_boxcheck;
document.getElementById("cbParamVirtual4").onclick = s_boxcheck;
document.getElementById("cbParamVirtual6").onclick = r_boxcheck;
document.getElementById("caspioform").onsubmit = transfer;

I can't seem to get this to work. Can anyone assist me?

Thank you in advance for the help.

Hello @wbuchanan,

The solution depends on the use case. If you need to add newly added values to the lookup table, Virtual fields are not the right choice.

Virtual fields don`t submit data into the table. This is why a separate Submission form is used in this tech tip:


1) So, if it is fine to add a value to the dropdown from the virtual field without adding this value to the Lookup table, this can be resolved in a rather easy way.

2) If the value should be added to the Lookup table, this is rather complex solution. It requires adding 3 Submission forms as iFrames and JavaScript code to get the submitted value to the dropdown as a new option.
