js中use或者using方法

看Vue.use方法，想起了以前工作中別人用過的use方法。

var YANMethod = {    using:function() {        var a = arguments, o = this, i = 0, j, d, arg, isExist;        arg = a[0], isExist = a[1];        if (arg && arg.indexOf(‘.‘)) {            d = arg.split(‘.‘);            for (j = (d[0] == ‘YAN‘) ? 1 : 0; j < d.length; j++) {                if(!o[d[j]] && isExist) return null;                o[d[j]] = o[d[j]] || {};                o = o[d[j]];            }        } else {            o[arg] = o[arg] || {};        }        return o;    },    /*--        用新Cookie方法，但是相容老的東西        -ver 2014-04-22    */    cookie:function(name, value, options) {        if(typeof value===‘undefined‘){            return Cookie.get(name);        }        if(options){            options.exp = typeof options.expires===‘number‘ ? options.expires * 24 :                options.expires; //原來的cookie是按天算的        }        Cookie.set(name, value, options);    },        /**     *JSON序列化，如果傳入的是字串則還原序列化為對象;若傳入的是對象則還原序列化為字串     */    json:function(value){        if(typeof value==="string"){            return this.jsontoObject(value);        }else{            return this.jsontoJSON(value);        }    },    jsontoJSON:function(object){        var type = typeof object;        if (‘object‘ == type) {            if (Array == object.constructor) type = ‘array‘;            else if (RegExp == object.constructor) type = ‘regexp‘;            else type = ‘object‘;        }        switch (type) {            case ‘undefined‘:            case ‘unknown‘:                return;            break;            case ‘function‘:            case ‘boolean‘:            case ‘regexp‘:                return object.toString();            break;            case ‘number‘:                return isFinite(object) ? object.toString() : ‘null‘;            break;            case ‘string‘:                return ‘"‘ + object.replace(/(\\|\")/g, "\\$1").replace(/\n|\r|\t/g, function() {                    var a = arguments[0];                    return (a == ‘\n‘) ? ‘\\n‘: (a == ‘\r‘) ? ‘\\r‘: (a == ‘\t‘) ? ‘\\t‘: ""                }) + ‘"‘;            break;            case ‘object‘:                if (object === null)                     return ‘null‘;                var results = [];                for (var property in object) {                    var value = this.jsontoJSON(object[property]);                    if (value !== undefined)                         results.push(this.jsontoJSON(property) + ‘:‘ + value);                }                return ‘{‘ + results.join(‘,‘) + ‘}‘;            break;            case ‘array‘:                var results = [];                for (var i = 0; i < object.length; i++) {                    var value = this.jsontoJSON(object[i]);                    if (value !== undefined)                         results.push(value);                }                return ‘[‘ + results.join(‘,‘) + ‘]‘;            break;        }    },        jsontoObject:function(strjson){        return eval("(" + strjson + ")");    }};var addFunToYAN = function(functionName,func){    if(typeof(func) == ‘function‘)        YAN[functionName] = func;};for(var m in YANMethod){    if(typeof(YAN[m]) == ‘undefined‘){        addFunToYAN(m,YANMethod[m]);    }}$.extend(YAN.using("Plugin"),{});$.extend(YAN.using("Utils"),{    getQuery:function(name){          var paramList = location.search.replace("?","").split("&");          for(var i = 0 ; i < paramList.length ; i++)          {              if(paramList[i].split("=")[0] == name){                  return paramList[i].substring(paramList[i].indexOf("=") + 1,paramList[i].length);              }          }          return null;    }});var Plugin = YAN.using(‘Plugin‘);Plugin.AD = ad;Plugin.AD.getFlashAd();window.AD || (window.AD = YAN.using(‘Plugin‘).AD);
