在MooTools中使用jQuery语法
有那么多的人使用jQuery库,早已习惯它的语法格式了。
jQuery众多实用的方法用起来的确非常方便。
那么如何在MooTools中使用像jQuery一样的语法格式那?MooTools着重在延伸能力上,这意味着你可以做任何你想做的事情,这是jQuery没办法办到的。 MooTools可以模仿jQuery,但是jQuery没办法模仿MooTools,如果你想要用类别或是延伸的原生原型物件等等MooTools的功能,你就得自己手动去写额外的程式。
接下来,我们就通过MooTools插件来完成jQuery一样的动作:jQuery syntax for MooTools 。

您好, 尽管我不是一个母语为汉语者, 我很欣赏你的教程. 代码是普遍的 ! And this is really a great find. Thank you.
我一方面是为了学习,一方面希望能够推动国内对MooTools库的学习和应用。jQuery可以做到的,MooTools也可以轻松做到。
看了,很好的教程。
博主,你实在是太牛X了,我是从jq转到mt的用户,很多语法确实不适应,看了你这篇文章实在受益匪浅. 感恩!
不过下边这个似乎是有错误的 html:function(value){ return value?this.set('html',value):this.get('html'); }, 改为 html:function(value){ return (typeOf(value)=='string')?this.set('html',value):this.get('html'); }, 在jquery的用法中 element.html('')的意思是将element的innerHTML值赋值为空,而不是get
请教博主一个问题,就是 Native.implement 似乎是MT1.3以前的版本的方法,请问在1.4中如何做?
另外请教一个问题 Native.implement似乎是MT1.3版以前的方法,请问在1.4之后如何做?
1.3 以上的Type就如1.2 的Native的进行了大量重构,Native => Type (see Core.js) 。 http://moocss.com/moodocs/index.php/core/Core/Core#Type https://github.com/mootools/mootools-core/wiki/Upgrade-from-1.2-to-1.3
