需要AngularJS输入表单例如选择用法 [英] Need example of select usage in AngularJS input form

问题描述

我在尝试使用对象的数组

I am attempting to use an array of objects

 (array = [{name: 'Moe', id:1}, {name: 'Larry', id:2}, {name: 'Curly', id:3}]) 

作为AngularJS输入表单中的下拉选择，我需要一个例子厉害。任何人都可以点我到的jsfiddle，可以告诉我吗？

as a drop-down selection within an AngularJS input form, and I need an example badly. Can anyone point me to a jsFiddle that can enlighten me?

推荐答案

我会建议使用NG-选择，您可以。

I would recommend using ng-options where you can.

<select ng-model="choice" ng-options="x.id as x.name for x in array"></select>

由于检查了这一点：你可以用它来选择的实际对象的：

Because check this out: You can use it to select actual objects:

app.controller('ExampleCtrl', function($scope) {
    $scope.items = [
        { id: 1, name: 'Foo' },
        { id: 2, name: 'Bar' }
    ];

    $scope.selectedItem = null;
});

<div ng-controller="ExampleCtrl">
    <select ng-model="selectedItem" 
            ng-options="item as item.name for item in items"></select>

    {{selectedItem | json}}
</div>

在当您选择从下拉的东西上面的例子中，它实际上是在设置一个将selectedItem整个对象引用，而只是一个值类型。

In the above example when you select something from the drop down, it's actually setting an entire object reference on selectedItem rather that just a value type.

注：使用NG选项设置你的值=属性在您的收藏项目的索引的这是由设计的。

NOTE: using ng-options sets your value="" attributes to the indices of the items in your collections this is by design.

这是真正做到这一点的最好办法。

It's really the best way to do it.

编辑：根据要求更多的上下文。此外这里是展示在使用它plunker
