在JSON角迭代 [英] angular iterate over json

问题描述

所以我有一个JSON，我试图让只有活跃用户所有的统计信息。当我尝试在for循环中是这样做的。

So I have a json and I am trying to get all the stats for active users only. when I try to do in a for loop something like this

for(var i=0; i < user.User.Stats.data.length; $i++;){
            return user.User.Stats[i].active === "1";    
}

这是行不通的。不过正常工作没有循环，只要我得到只有一条记录

it doesn't work ...however works fine without for loop as long as I am getting only one record

return user.User.Stats[i].active === "1"; 

这是我的HTML

here is my html

<div ng-controller="MyCtrl">
<div ng-repeat="user in _users | filter:isActive">
    {{user.User.userid}}
</div>
</div>

这是我的js

var myApp = angular.module('myApp', []);

function MyCtrl($scope) {

    $scope.isActive = function(user) {
       // for(var i=0; i < user.User.Stats.data.length; $i++;){
            return user.User.Stats[0].active === "1";    
       // }

    };

    $scope._users = [
        {
        "User": {
            "userid": "19571",
            "status": "7",
            "active": "1",
            "lastlogin": "1339759025307",
            "Stats": [
                {
                "active": "1",
                "catid": "10918",
                "typeid": "71",
                "Credits": [
                    {
                    "content": "917,65",
                    "active": "1",
                    "type": "C7"},
                {
                    "content": "125,65",
                    "active": "1",
                    "type": "B2"}
                ]},
                                {
                "active": "1",
                "catid": "10918",
                "typeid": "71",
                "Credits": [
                    {
                    "content": "917,65",
                    "active": "1",
                    "type": "C7"},
                {
                    "content": "125,65",
                    "active": "1",
                    "type": "B2"}
                ]}
            ]
        }}];
}

推荐答案

没有什么复杂的，它只是你的语法是错误的。

Nothing complicated, it’s just that your syntax is wrong.

for循环需要这样写：

The for loop needs to be written like this:

for(var i=0; i < user.User.Stats.length; i++)

即。没有多余的 $ ，没有多余的; ，也没有数据在统计信息。

I.e. without the superfluous $, without the superfluous ;, and also there is no data inside Stats.

另外请注意，你可以使用 angular.forEach 来代替。

Also note you could use angular.forEach instead.
