js遍历json对象

var jsondata = yourdata; for(var x in jsondata){ document.write(x+"="+jsondata[x]); } 如果是jsonarray就外面套一层for即可 var jsonarray =yourarray; for(var i =0;i

Js代码 getJson('age'); function getJson(key){ var jsonObj={"name":"傅红雪","age":"24","profession":"刺客"}; //1、使用eval方法 var eValue=eval('jsonObj.'+key); alert(eValue); //2、遍历Json串获取其属性 for(var item in jsonObj){ i...

因为你没有给str1初值, 所以str1一开始是undefined 然後undefined和字符串做+操作会把undefined转换为字符串'undefined'後拼接 从而得到你不期望的结果 你需要 var str1 = ''for(key in json1){str1 += key + " " + json1[key] + " ";};

var typeArr = new Array();for(var i = 0;i

var jsondata = yourdata; for(var x in jsondata){ document.write(x+"="+jsondata[x]); } 如果是jsonarray就外面套一层for即可 var jsonarray =yourarray; for(var i =0;i

$(function(){ $.ajax({ type:'GET', url:'{siteurl($siteid)}/api.php', dataType:'json', success: function(data) { var wrap = $("#a"); for(var key in data) { wrap.append($("").html(key + ': ' + data[key])); } } });});

window.onload = function () { var datanav = [{ "name": "张三", "position": "1", "powerrate": "2", "waterrate": "3", "healthcosts": "4", "watermeter": "5", "ammeter": "6", "linkman": "7", "phone": "8", "rental": "9", "tenancy": ...

于json对像,怎么遍历json对象的所有key,在使用json对象时,如果无法知道key,请参阅下面的关键代码: var smsTypeDesc = {"4":"回访短信","3":"邮件短信","aa":"测试短信"}; function EnumaKey(){ for(var key in smsTypeDesc){ alert(key); }...

var obj = { "a": 1, "b": 2, "c": "ssss"};for(var o in obj) { console.log("key: " + o + "-------value: "+ obj[o]);}

var list = {"id":1,"key":101,"value":"value"};var str = "";for(var name in list){ str+=name+"="+list[name].toString();}alert(str);
