动态NG-模型NG重复 [英] Dynamic ng-model in ng-repeat

问题描述

采用了棱角分明的JS，我有这样的对象

Using Angular JS, I have this object

var pages = [ 
    { name: 'users', title : "Users" }, 
    { name: 'roles', title : 'Roles' }
];

我试图创建的用户角色的页面。对于我需要4个复选框的每一页。每个页面都要有4个规则。访问，显示，编辑，删除。

I'm trying to create a page for user roles. For that I need 4 checkboxes for each page. Each page must have 4 rules. Access, show, edit, delete.

在NG重复显示的页面

<div ng-controller='PageCtrl'>
   <ul>
     <li ng-repeat='page in pages'>
        {{ page.title }}
        <input type="checkbox" name="access"> Access
        <input type="checkbox" name="show"> Show
        <input type="checkbox" name="edit"> Edit
        <input type="checkbox" name="delete"> Delete
     </li>
   </ul>
</div>

所以，我需要将这些复选框值传递到$范围。我如何可以绑定一个模型每个复选框？

So I need to pass those checkboxes values to the $scope. How can I bind a model for each checkbox?

筛选

<input type="checkbox" name="access" ng-model='page.name+_access'> Access

复选框型号名称应与page.name开始。像users_access，users_show ...

Checkbox model name should start with page.name. Like users_access, users_show...

推荐答案

您可以使用下面的语法：

You can use the following syntax:

ng-model="page[page.name+'_access']"

但作为事实上，它看起来可以将这些群体纳入控制器为好，然后用另一NG-重复。像这样的：

But as a matter of fact, it looks one can move those groups into controller as well, then use another ng-repeat. Like this:

HTML：

<div ng-controller="PageCtrl">
    <ul>
        <li ng-repeat='page in pages'>{{ page.title }}
            <label ng-repeat="right in rights">
                <input type="checkbox" ng-model="page[page.name + '_' + right]" name="{{right}}" />{{right|capitalize}}</label>
            <button ng-click="log(page)">Log</button>
        </li>
    </ul>
</div>

JS：

var module = angular.module('myAp', [])
    .controller('PageCtrl', ['$scope', function ($scope) {
    $scope.pages = [{
        name: 'users',
        title: "Users"
    }, {
        name: 'roles',
        title: 'Roles'
    }];
    $scope.rights = ['access', 'show', 'edit', 'delete'];

    $scope.log = function (page) {
        console.log(page);
    }
}]).filter('capitalize', function() {
    return function (value) {
        return value.charAt(0).toUpperCase() + value.slice(1);
    };
});

演示 。
