js jsonArrAy 遍历

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

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

jq框架下,给个示例,仅供参考: var objs = $.parseJSON('[{"name":"aaa","age":"22"},{"name":"bbb","age":"33"}]');var str = '';$.each(objs, function(k, obj){ str += obj.name + ' is ' + obj.age + "\n";});alert(str);

var data = [{ id: 0, chiild: [{ msg: '111' }, { msg: '222'}] }, { id: 3, chiild: [{ msg: '444' }, { msg: '555'}] }, { id: 2, chiild: [{ msg: '467' }, { msg: '58912'}]}]; var str = ""; var strmsg = ""; for (var i = 0; i < data....

json 数组也是数组 //1、var jsonstr="[{'name':'a','value':1},{'name':'b','value':2}]";var jsonarray = eval('('+jsonstr+')'); var arr = { "name" : $('#names').val(), "value" : $('#values').val() }jsonarray.push(arr);//2、var json...

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 origin = [{"first_id":1,"first_name":"中学","second_id":"1-1","second_name":"一年级","third_id":"1-1-1","third_name":"一年级一班","people":10,"age":10,"parent":5},{"first_id":1,"first_name":"中学","second_id":"1-1","second_...

例如数据库里面的json字符串是这样的 ? 1 2 3 4 5 var str = '[{"name":"宗2瓜","num":"1","price":"122"},{"name":"宗呱呱","num":"1","price":"100"}]'; var xqo = eval('(' + str + ')'); for(var i in xqo){ alert(xqo[i].name); } 上面的是...

如果这个数组不是json的话,就可以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...
