/* 题目: jquery.data
* 描述: 使用data的模式和反模式
*/
// 在编程中,一般的框架有两种函数:
// 一种是低级 low-level function
// 一种是高级 high-level function
jQuery.extend({
data:function(){
}
});
$.xxx();
jQuery.fn.extend({
data:function(){
}
});
$().xxx();
//低级的一般用于内部的运算,性能高但是更接近机器语言,
//高级的一般是面向广大开发者的,更方便使用但是性能参差不齐。
// 反模式
$(elem).data(key, value);
// 模式
$.data(elem, key, value);
// 参考
