onChange Client Script setValue

[jmichael]

onChange script not working. Needs to set two fields bases off of a reference field selection. Base field value is selected from the reference the description then needs to populate of that item and the type of item. The description field is a normal string field and the type is a choice field. These can both be set without a Script Include, but its not working. I'm sure its a problem with the script.

How should the syntax look for this?

If I've read and understood your question...You have a (assume custom) table that holds a "u_description" string field and a "u_type" choice field. Your form (assume change_request) has a reference field to this (custom) table and onchange of this reference, you want to populate the description and type fields of the current (change_request) form. I also go further to assume that the option for the choice field is readily available and does not need to be added dynamically.

//On change of the reference field to the (custom) table

function onChange(control, oldValue, newValue, isLoading) {
//If the form is loading, do nothing
     if (isLoading)
           return;

//If the description and type fields are not on the form, do nothing
//---assuming these fields are OOB, hence are not prefixed with u_
     if (!g_form.getControl('description') && !g_form.getControl('type'))
           return;

//If the reference field was cleared, clear the description and type fields
     if (newValue == '') {
           setMyFields();
           return;
     }

//If we got this far, 
//-the form is not loading, 
//-the other fields are on the form
//-the reference field has a value
//time to make a server call

//control.id.split('.')[1] is just a shortcut to the name of the field triggering this onchange script
     g_form.getReference(control.id.split('.')[1], setMyFields);
}

//This function will either set or clear the field values
function setMyFields(serverRecord) {
             var myDesc = (!serverRecord) ? '' : serverRecord.u_description; //u_description is a string field of the (custom) table
             var myType = (!serverRecord) ? '' : serverRecord.u_type; //u_type is a choice field, so this needs to be the choice value, not the display value
             //---assuming these fields are OOB, hence are not prefixed with u_
             g_form.setValue('description', myDesc);
             g_form.setValue('type', myType);
}
