Adding Zip Code Fields on a form

If You are adding a US Zip Code Field to a form, you can build it as a string field from configure form design and restrict the Maximum length to 5.
You can then add an onChange Client Script on the field to validate the entries and add this code:
function onChange(control, oldValue, newValue, isLoading, isTemplate) { if (isLoading || newValue === '') { return; } var newVal = newValue.toString().length; if (newVal != 5) { g_form.showFieldMsg('u_zip_code', 'Please add a 5 digit Zip Code', 'error'); } var re = /^[0-9]*$/; if (!re.test(newValue)) { g_form.showFieldMsg('u_zip_code', 'Please add a valid zip code', 'error'); return false; } return true; }
- The code verifies for you if the Zip Code is indeed 5 digits and since the field is a String, it also makes sure you don’t include alphabets in the field.
- Note: Replace u_zip_code with the name of your field and this will not work for zip codes in the format of 12345-1234.
