jquery.transform

jquery.transform2d.js adds 2d transform capabilities to jQuery `css()` and `animate()` functions. [Demo](http://louisremi.github.com/jquery.transform.js/index.html) Usage: ====== Set transform with a string --------------------------- $(elem).css('transform', 'translate(50px, 30px) rotate(25deg) scale(2,.5) skewX(-35deg)'); $(elem).animate({transform: 'translateY(-100px) rotate(1rad) scaleX(2) skewY(42deg)'}); You can use the following list of transform functions: - `translateX(<number>px)` - `translateY(<number>px)` - combined: `translate(<number>px, <number>px)` *the second number is optional and defaults to 0* - `scaleX(<number>)` - `scaleY(<number>)` - combined: `scale(<number>, <number>)` *the second number is optional and defaults to the value of the first one* - `rotate(<angle>)` *units for angles are *rad* (default), *deg* or *grad*.* - `skewX(<angle>)` - `skewY(<angle>)` - `matrix(<number>, <number>, <number>, <number>, <number>, <number>)`* *`matrix` gives you more control about the resulting transformation, using a [matrix construction set](http://www.useragentman.com/matrix/). When using it in animations however, it makes it impossible to predict how the current and target transformations are going to be interpolated; there is no way to tell whether elements are going to rotate clockwise or anti-clockwise for instance. Get transform ------------- returns a computed transform matrix. $(elem).css('transform') == 'matrix(0,1,-1,0,100,50)'; Relative animations ------------------- Relative animations are possible by prepending "+=" to the transform string. $(elem).css('transform', 'rotate(45deg)'); // using the following syntax, elem will always rotate 90deg anticlockwise $(elem).animate({transform: '+=rotate(-90deg)'}); Limitations: ============ - requires jQuery 1.4.3+, - Should you use the *translate* property, then your elements need to be absolutely positionned in a relatively positionned wrapper **or it will fail in IE**, - transformOrigin is not accessible. Why such restrictions with 'translate'? --------------------------------------- Since translate is unavailable in IE<9, we have to emulate it using *top* and *left* properties of the element style. This can, of course, only work if the elements are absolutely positionned in a relatively positionned wrapper. Other plugins position the elements and wrap them transparently. I think that transparently messing with the DOM often introduces unpredictible behavior. Unpredictible behavior leads developpers to fear plugins. *Fear leads to anger. Anger leads to hate. Hate leads to suffering.* I prefer leaving this up to you. License ======= Dual licensed under GPL and MIT licenses. Copyright (c) 2010 [Louis-Rémi Babé](http://twitter.com/louis_remi).
