Js 怎么遍历json对象所有kEy及根据动态kEy获取值

将json转化为数组, 然后进行for循环, 如: var arr = 数组; for(var i=0;i

var json = {a : 1,b : 2}for( i in json){console.log(i);console.log(json[i]);}

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

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...

var obj = {};for(var k in obj) { //遍历对象,k即为key,obj[k]为当前k对应的值 console.log(obj[k]);}

var obj = {"a": "aa","b": "bb"}; for(var o in obj){ console.log('Key is ' + o + ';value is ' + obj[o]); }

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

可以按key值排序 代码如下: var mobile = str[1].substring(1); var conferenceId=str[2]; var callType=str[3]; //报警处理(通过预定义的+H组) var isAlarm=false; if(callType=='3'){ //预定义组呼入 var preGroup=this.homeU.preGroup; var ...

一般来说是这样的key为属性名,obj为对象,obj[key]属性值 for(var key in obj){ console.log(obj[key]); }

json是种常用数据传输格式,js怎么解析json格式的数据呢,请参阅下面的代码: [html] view plain copy print? var data = '{"return_code":0,"return_message":"success","data":{"data":[{"id":"1","question":"公主令牌在哪交?"},{"id":"2","...
