README

Forms usually need to be submitted once.

When double submission does occur (i.e. because of double clicking), unwanted side effect can occur:

• duplication of records in a database
• multiple actions such as i.e. sending duplicate emails
• thrown exceptions as systems could not expect certain actions to be executed twice

This "Js-SubmitOnce" script is a plain JS vanilla script to prevent this undesired behavior.

Installation

Installation is done by composer, requiring:

{
  "require": {
   "dynasource/js-submitonce" : "*"
  }
}

Include it in your webpage with:

window.addEventListener('load', function () {
    new SubmitOnce({
        'selector': 'btn'
    });
});
