Question

可以在ng-model指令中使用范围变量的键吗？

我想要的不是手动为每个ng-model指令设置键，我只想使用ng-repeat并获取范围变量的关键字并将其放在ng-repeat内的ng-model中指示。

我只是这个框架的新手。任何帮助将不胜感激

您期待这个视图请看一下，是的，可以使用键作为ng-model 嘿伙计你使用角度1.0.1版本，这就是为什么你可以编辑一次和焦点出来使用最新版本检查相同的演示

html代码

<div classs="container" ng-app="app" ng-controller="UserProfile">
        <ul>
            <li ng-repeat="user in users"><a href="" ng-click="editProfile(user.id)">{{user.id}} - {{user.fname}} </a></li>

            <input ng-repeat="(key, value) in editing" ng-model="editing[key]">

<强> angular.js

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

function UserProfile ($scope) {
  $scope.users = {
    "ID01": {
      "id": "ID01",
      "fname": "Vincent",
      "lname": "Panugaling",
      "gender": "male",
      "age": "21",
    },
    "ID02": {
      "id": "ID02",
      "fname": "Adrian",
      "lname": "Santos",
      "gender": "male",
      "age": "22"
    },
    "ID03": {
      "id": "ID03",
      "fname": "Incognito",
      "lname": "Mode",
      "gender": "female",
      "age": "21"
    }
  };

  $scope.editProfile = function (id) {
    $scope.editing = $scope.users[id];
  };
}

使用键和值进行ng-repeat，然后使用该键作为ng-model的指令值
