Script Categories













Forms >>> Auto Tab.

Automatically sets focus to the next form element when the current form element's maxlength has been reached. This way, the user does not have to manually click in or tab to the next field. This script is perfectly suited for constant-length strings such as a phone number or social security numbers.

Phone Number :
1 - ( ) - -
Social Security Number :
- -

if(input.value.length >= len && !containsElement(filter,keyCode)) {
input.value = input.value.slice(0, len);
