JS debug breakpoint / log snippets

stopBefore.js

2min screencast

These tools inject a breakpoint, console.log or console.count in any function you want to spy on via stopBefore('Element.prototype.removeChild') or ditto stopAfter, logBefore / logAfter / logAround / logCount.

Works in Chrome DevTools and Safari Inspector; Firefox dev tools reportedly less so.

Prepend the debugger statement to a function as easy as stopBefore('Element.prototype.removeChild'). Works in Chrome DevTools and Safari Inspector, doesn’t work in Firebug‘s and Firefox Developer Tools‘ console (I don’t know why). Works as a standalone script everywhere.

stopBefore.js

2min screencast

Examples

stopBefore(document, 'getElementById')
stopBefore('document.getElementById') // the same as the previous
stopBefore(Element.prototype, 'removeChild')

iOS6 webkit timer bug workaround
(function (window) {
// This library re-implements setTimeout, setInterval, clearTimeout, clearInterval for iOS6.
// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
// This code is free to use by anyone (MIT, blabla).
// Original Author: [email protected]
var timeouts = {};
