Is there a way to check to see if a field is visible within a script?

[galavodasal]

I have this simple onSubmit script to check to see if the user entered at least 12 digits into a field. The problem is, this field isn't always shown on the catalog item. The mac_address field only appears (and becomes mandatory) if another field is set to X.

I was looking in the scripting wiki and saw the g_form.setVisible, but I'm not sure if I can use that in this case.

I tried adding if (g_form.setVisible('mac_address', true)) {   but that just made the entire script fail.

function onSubmit() {

    //Type appropriate comment here, and begin script below

if

  var mac = g_form.getValue('mac_address');  

if (mac.toString().length < 12) { // or whatever number you want  

      g_form.setValue('mac_address','');  

      alert('Please enter the full 12 digit MAC address.');  

}  

}

Thanks!

Hi Alexander,

Could you please elaborate your requirement with more clarity? What actually is the requirement? I mean to say when do you want to see the particular field and when not.

Thanks,

Hey Arnab, Chuck was able to point me in the right direction but thanks for your reply.
