What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

jQuery Validate Hooks

If you're using [ASP.NET MVC3][], it uses [jQuery Validate][] to do client-side validations. Instead of using [jQuery Validate][] directly, however, it wraps it with its own jQuery plugin called [jQuery.Validate.Unobtrusive][]. [jQuery.Validate.Unobtrusive][] sets up [jQuery Validate][] for you, behind the scenes, so you don't have an opportunity to customize your [jQuery Validate][] settings at all!

We've been running into trouble with this when we've been doing our own custom client-side validations. We need a way to integrate with the build-in [ASP.NET MVC3][] validation so we can:

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}
