js怎样读取json里面的数据
收集整理：
var json = { contry:{ area:{ man:"12万", women:"10万" } } }; //方式一：使用eval解析 var obj = eval(json); alert(obj.constructor); alert(obj.contry.area.women); //方式二：使用Funtion函数 var strJSON = "{name:'json name'}";//得到的JSON var obj = new Function("return" + strJSON)();//转换后的JSON对象 alert(obj.name);//json name alert(obj.constructor); //复杂一点的json数组数据的解析 var value1 = [{"c01":"1","c02":"2","c03":"3"}, {"c01":"2","c02":"4","c03":"5"}, {"c01":"5","c02":"1","c03":"4"}]; var obj1 = eval(value1); alert(obj1[0].c01); //复杂一点的json数组数据的解析;获取键名 var value1 = [{"c01":"1","c02":"2"}, {"c01":"2","c02":"4"}, {"c01":"5","c02":"1"}]; var a3 = eval(value1); $.each(a3, function (i) { //$('#' + a1 ).append(new Option(a3[i].c02, a3[i].c01 )); //$('#' + a1 ).append(new Option(a3[i]['c02'], a3[i]['c01'] )); var a31=Object.keys(a3[i])[0]; //第1个键名c01 var count= Object.keys(a3[i]).length; //number of elements(a3[i]) var a32=Object.keys(a3[i])[1];} //第2个键名c02 $('#' + a1 ).append(new Option( a3[i][a32], a3[i][a31] )); }); } //复杂一点的json的另一种形式 var value2 = {"list":[ {"password":"1230","username":"coolcooldool"}, {"password":"thisis2","username":"okokok"}], "array":[{"password":"1230","username":"coolcooldool"},{"password":"thisis2","username":"okokok"}]}; var obj2 = eval(value2); alert(obj2.list[0].password); - 版权声明：文章来源于网络采集，版权归原创者所有，均已注明来源，如未注明可能来源未知，如有侵权请联系管理员删除。
