WeHateCaptchas is a form verification service created by Edward Dalton, now maintained by Cohan Robinson designed to "timeout" bots, rather than out think them. Examples here: HTML, PHP
Here we've altered the Javascript aspect from the example to add some extra benefits.
To include in a project, upload or copy dist/whc-plugin.umd.js to your project, and add the necessary parameters below.
If you only need to support more modern browsers, you can use the js inside of dist/whc-plugin.modern.js
id = whcScriptTag required
use getElementsByClassName
data-form a class name for the forms on the page.
data-button a class name for the submit buttons/inputs on the page.
data-debug: A boolean for getting more information about what is going on behind the scenes. Accepted values are any Integer, 'true' or 'false', ''.
While you can use 'false', it is an anti-pattern and should be avoided in production.
data-difficulty: A number between 1 - 10. Determines the number of "questions" to answer before marking the user as verified.
data-finished: The text/value of the element after verified.
data-progress: Visual representation of the verification progress
Private.time The time the verification starts
Private.script The script element
Private.form Current form
Private.button Current submit button
Private.difficulty The difficulty of the verification process, either the default (5), the data-difficulty of the only button/input on the page, or an average of all on the page.
Private.eventName Internal event name for debugging
Private.workerFunc Inline WebWorker function
Private.worker The WebWorker after it is creater
Private.debug A function that checks all the forms for a debug value, turns on extra debugging features if true
To limit Global variables, if Private.debug is true, it will add window.WHCDetails with an object including all the forms, buttons, and the current difficulty.
