|

* IMPORTANT NOTICE FOR DEVELOPERS:
|
||||
* The logic in this file is intended to run in legacy browsers. Avoid any use of:
|
||||
* - ES6 or newer in general
|
||||
* - jQuery (doesn't work in older browsers)
|
||||
* - ES5 or newer in general
|
||||
* - const/let, use the traditional var declarations instead
|
||||
* - async/await or Promises, use traditional callbacks
|
||||
* - shorthand function notation "() => output", use the full "function() {return output;}" style
|
||||
* - IE doesn't support:
|
||||
* - URL(), use the traditional window.location object
|
||||
* - endsWith(), use indexof()
|
||||
* - yes, this logic needs to support IE 5 or 6, to at least display the error message
|
||||
* - yes, this logic needs to support IE 6, to at least display the error message
