先来个全局变量 及定义默认的数据类型
1: var framework = {
2: //定义常用的js类型
3: type : {
4: nothing : -1,
5: undefined : 0,
6: string : 1,
7: number : 2,
8: array : 3,
9: regex : 4,
10: bool : 5,
11: method : 6,
12: datetime : 7,
13: object : 8
14: },
15: types:{},
16: addType:function(type,compare){
17: framework.types[type]=compare
18: }
19: };
21: //默认的数据类型判断
22: framework.addType(framework.type.nothing, function (value) {
23: return value == null;
24: });
25: framework.addType(framework.type.array, function (value) {
26: return value instanceof Array;
27: });
28: framework.addType(framework.type.string, function (value) {
29: return value.substr && value.toLowerCase;
30: });
31: framework.addType(framework.type.number, function (value) {
32: return value.toFixed && value.toExponential;
33: });
34: framework.addType(framework.type.regex, function (value) {
35: return value instanceof RegExp;
36: });
37: framework.addType(framework.type.bool, function (value) {
38: return value == true || value == false;
39: });
40: framework.addType(framework.type.method, function (value) {
41: return value instanceof Function;
42: });
43: framework.addType(framework.type.datetime, function (value) {
44: return value instanceof Date;
45: });
哥本来还担心没啥东西,一贴这点代码就有点心虚了，有兴趣的悠着点耐心点，后面估计还有段距离呀。。。。下面开始进入主题吧。
回到目录
先上两个小菜
废话就不多说了，直接贴代码，这个应该是个人都能看懂的哈，不解释。。。
1: framework.util = {
2: //转换成字符串
3: toString : function (val) {
4: return val == null ? "" : val.toString();
5: },
6:
7: //去除字符串首尾空格
8: trim : function (value) {
9: value = value == null ? "" : value;
10: value = value.toString();
11: return value.replace(/^\s*|\s*$/g, "");
12: },
13: getType : function (obj) {
14:
15: if (obj == null) {
16: return framework.type.nothing;
17: }
18: for (var item in framework.types) {
19: if (framework.types[item](obj)) {
20: return item;
21: }
22: }
23: //不匹配已定义的默认类型，就返回object
24: return framework.type.object;
25: },
26: isType : function (type, value) {
27: return framework.util.getType(value) == type;
28: }
29: }
30: 菜上完了，先尝下合不合口啊，敲代码习惯性敲一点验证下，这样改起来能够比较快捷的定位到问题在哪。
1: var log =console.log;
2: log(framework.util.getType(null)); // -1 nothing
3: log(framework.util.getType("aaa")); // 1 string
4: log(framework.util.getType(framework)); // 8 object
5: log(framework.util.getType(function(){})); //6 method
6: log(framework.util.getType(3232)); //2 number
7: log(framework.util.getType([])); //3 array
8: log(framework.util.getType(true)); //5 bool
9: log(framework.util.getType(new Date())); //7 datetime
比较幸运的一次性通过了，没敲错字母，看好了，要发力了。我觉得还是一次性上完算了。别拖拖拉拉的了。
这里直接贴util 对象中的方法啦。不重复贴上面的代码，测试的自己合并一下就可以了。
1: //遍历集合对象
2: each : function (collection, action) {
3: var index = 0;
4: for (var item in collection) {
5: if (collection.hasOwnProperty(item))
6: action(collection[item], index++);
7: }
8: },
9:
10: clone : function (obj) {
11: //判断是否是数组，是数组克隆每一项
12: if (framework.util.isType(framework.type.array, obj)) {
13: return framework.util.cloneArray(obj);
14: }
15: //克隆对象中的值
16: else if (framework.util.isType(framework.type.object, obj)) {
17: var clone = {};
18: for (var item in obj) {
19: if (obj.hasOwnProperty(item)) //去掉原型链中的属性
20: clone[item] = framework.util.clone(obj[item]);
21: }
22: return clone;
23: }
24: //如果是其他类型，则直接返回其值
25: else {
26: return obj;
27: }
28: },
29:
30: //进行数组克隆
31: cloneArray : function (array) {
32: var result = [];

这个大餐是上完了，验证下有没有效果吧。先上个简单的，出错了免得出丑。
1: var a =new People(12,"abc");
2: var b = a;
3: var c = framework.util.clone(a);
4: log(b==a); //true
5: log(c==a); //false
6: log(c); //当然别忘了验证下值是否相等。
最后证明还是可行的，当然这个不是重点，重点在下面，能不能进行深度克隆，这里为People 添加一个属性
2: var a =new People(12,"abc",[12,"bb"]);
3: var b = a;
4: var c = framework.util.clone(a);
5: log(b==a); //true
6: log(c==a); //false
7: log(c); //当然别忘了验证下值是否相等。
log(a.child==c.child); //false ==判断是对象的引用是否相等，所以这里为false ,本来是想要true的，看下面的语句：
log( framework.util.equals(a,c)) //true 这里返回的是我所想要的结果。
在这里其他的函数就不一一展示了，如果感兴趣的自己验证下结果。
另这个 深度 判断相等并没有做到完美，在数组中存在的对象如果顺序调换下，还是会判断为false ,哪位如果有好的方法可以帮我改进一下。
最好能做到如下两个结果是相等的。。
a={id:5,name:"dd",[12,value:{id:8,name:”dd”}]}
b={name:”dd”,id:5,[12,value:{name:”dd”,id:8}]}
