zepto的原型 $.fn 属性：
constructor //构造行数
forEach: emptyArray.forEach, //都是原生数组的函数
reduce: emptyArray.reduce,
push: emptyArray.push,
sort: emptyArray.sort,
splice: emptyArray.splice,
indexOf: emptyArray.indexOf,
concat //合并数组，这里还包含了合并节点集合
add //添加节点集合
is //匹配是否包含该选择器
find: function(selector){
var result, $this = this
if (!selector) result = $()
else if (typeof selector == ‘object‘)
result = $(selector).filter(function(){
var node = this
return emptyArray.some.call($this, function(parent){
return $.contains(parent, node)
})
})
else if (this.length == 1) result = $(zepto.qsa(this[0], selector))
else result = this.map(function(){ return zepto.qsa(this, selector) })
return result
},
emptyArray.some() http://www.cnblogs.com/jiebba/p/6514067.html 可以看看js几种遍历不同
pluck 根据属性来返回节点集合
// 设置宽高
;[‘width‘, ‘height‘].forEach(function(dimension){
var dimensionProperty =
dimension.replace(/./, function(m){ return m[0].toUpperCase() })
$.fn[dimension] = function(value){
var offset, el = this[0]
if (value === undefined) return isWindow(el) ? el[‘inner‘ + dimensionProperty] :
isDocument(el) ? el.documentElement[‘scroll‘ + dimensionProperty] :
(offset = this.offset()) && offset[dimension]
else return this.each(function(idx){
el = $(this)
el.css(dimension, funcArg(this, value, idx, el[dimension]()))
})
}
})
//添加函数`after`, `prepend`, `before`, `append`,
adjacencyOperators.forEach(function(operator, operatorIndex) { var inside = operatorIndex % 2 //=> prepend, append $.fn[operator] = function(){ // arguments can be nodes, arrays of nodes, Zepto objects and HTML strings var argType, nodes = $.map(arguments, function(arg) { var arr = []
zepto.Z.prototype = Z.prototype = $.fn
绑定到原型上面
window.Zepto = Zepto
window.$ === undefined && (window.$ = Zepto)
//绑定在全局
代码仅供参考，具体功能可以自己扩展。
