在工作中需要将JavaScript中的对象转化为字符串，于是使用dojo widget的方式写了一套方法，从而可以实现JS对象转化为字符串，具体实现如下：
dojo.provide("JSONObject");dojo.require("dijit._Widget");dojo.declare("JSONObject", [dijit._Widget], {iContext: null,toJSON: function() {var json = [];for (var i in this.iContext) {if (!this.iContext.hasOwnProperty(i)) continue;if (this.iContext[i] == null)json.push(new JSONString({"iContext": i}).toJSON() + " : " +"null");else if (typeof this.iContext[i] == "object")json.push(new JSONString({"iContext": i}).toJSON() + " : " +new JSONObject({"iContext": this.iContext[i]}).toJSON());else if (typeof this.iContext[i] == "array")json.push(new JSONString({"iContext": i}).toJSON() + " : " +new JSONArray({"iContext": this.iContext[i]}).toJSON());else if (typeof this.iContext[i] == "string")json.push(new JSONString({"iContext": i}).toJSON() + " : " +new JSONString({"iContext": this.iContext[i]}).toJSON());else if (typeof this.iContext[i] == "boolean" || typeof this.iContext[i] == "function" || typeof this.iContext[i] == "number" || typeof this.iContext[i] == "regexp")json.push(new JSONString({"iContext": i}).toJSON() + " : " +this.iContext[i]);}return "{/n " + json.join(",/n ") + "/n}";}});dojo.declare("JSONArray", [dijit._Widget], {iContext: null,toJSON: function() {for(var i=0,json=[];i<this.iContext.length;i++)if (this.iContext[i] == null)json[i] = "null";else if (typeof this.iContext[i] == "object")json[i] = new JSONObject({"iContext": this.iContext[i]}).toJSON();else if (typeof this.iContext[i] == "array")json[i] = new JSONArray({"iContext": this.iContext[i]}).toJSON();else if (typeof this.iContext[i] == "string")json[i] = new JSONString({"iContext": this.iContext[i]}).toJSON();else if (typeof this.iContext[i] == "boolean" || typeof this.iContext[i] == "function" || typeof this.iContext[i] == "number" || typeof this.iContext[i] == "regexp")json[i] = this.iContext[i];return "[" + json.join(", ") + "]";}});dojo.declare("JSONString", [dijit._Widget], {iContext: null,toJSON: function() {return '"' + this.iContext.replace(/(//|/")/g,"//$1").replace(//n|/r|/t/g,function(){var a = arguments[0];return (a == '/n') ? '//n':(a == '/r') ? '//r':(a == '/t') ? '//t': "";}) + '"';}});
调用如上写的dojo widget实现JS对象转化为字符串，如下：
<html lang="en"><head><mce:script djconfig="parseOnLoad: true, isDebug: false" src="dojotoolkit/dojo/dojo.js" mce_src="dojotoolkit/dojo/dojo.js" type="text/javascript"></mce:script><mce:script type="text/javascript" src="json.js" mce_src="json.js"></mce:script><mce:script type="text/javascript"><!--dojo.require("JSONObject");// --></mce:script><mce:script type="text/javascript"><!--function b(){this.B = "bbbb";this.B1 = 1111;}function a(){this.A = "aaaa";this.AO = new b();}var strValue = new JSONObject({iContext: new a()}).toJSON();// --></mce:script></head><body></body></html>
注：其中文件json.js是上边dojo widget实现存放的位置。
