這篇文章主要介紹了將json對象轉換為字符串的方法,需要的朋友可以參考下
代碼如下: /* 將json對象轉換為字符串 使用方法: var json = {id=3,name="abc"}; var str = tools.j2s(json); */ tools.j2s = function(O) { var S = []; var J = ""; if (Object.prototype.toString.apply(O) === '[object Array]') { for ( var i = 0; i < O.length; i++) { S.push(this.j2s(O[i])); } J = '[' + S.join(',') + ']'; } else if (Object.prototype.toString.apply(O) === '[object Date]') { J = "new Date(" + O.getTime() + ")"; } else if (Object.prototype.toString.apply(O) === '[object RegExp]' || Object.prototype.toString.apply(O) === '[object Function]') { J = O.toString(); } else if (Object.prototype.toString.apply(O) === '[object Object]') { for ( var i in O) { var tempObj = ""; if(typeof (O[i]) == 'string') { tempObj = '"' + O[i] + '"'; } else if(typeof (O[i]) === 'object') { tempObj = this.j2s(O[i]); } else { tempObj = O[i]; } S.push('"' + i + '":' + tempObj); } J = '{' + S.join(',') + '}'; } else if (Object.prototype.toString.apply(O) === '[object String]') { J = '"' + O + '"'; } else { J = O; } return J; }; //json字符串轉換為json對象 tools.s2j = function(jsonString) { if(jsonString == null || jsonString == "" ) { jsonString = "{}"; } return eval('('+jsonString+')'); }; //JSON字符串到Object tools.json2Obj = function(_json) { if (_json == '') { //alert("函數初始化失敗！"); return ""; } return eval("({root:"+_json+"})"); };
