angular-ui-select - 如何将对象属性绑定到 ng-model [英] angular- ui-select - how to bind object property to ng-model

问题描述

我在一个简单的用户注册表中使用 angular-ui-select:

i'm using the angular-ui-select in a simple user registration form:

<ui-select ng-model="user.countryCode" convert-to-string theme="selectize" class="dropdown">
    <ui-select-match placeholder="{{::strings('userDetails.countryPlaceholder')}}">{{$select.selected.name}}
    </ui-select-match>
    <ui-select-choices repeat="country in countries">
        <span ng-bind-html="country.name | highlight: $select.search"></span>
    </ui-select-choices>
</ui-select>

这是我的国家/地区数组定义:

Here's my countries array definition:

$scope.countries = [
            {name: 'Afghanistan', code: 'AF'},
            {name: 'Albania', code: 'AL'},
            {name: 'Australia', code: 'AU'},
            {name: 'Austria', code: 'AT'},
            {name: 'Azerbaijan', code: 'AZ'},
            {name: 'Belarus', code: 'BY'},
            {name: 'Belgium', code: 'BE'},
            {name: 'Belize', code: 'BZ'},
            {name: 'Benin', code: 'BJ'}
];

我在我的 html 中创建用户对象，每个字段都有一个绑定到用户某些属性的 ng-model.当我使用诸如 firstName 之类的简单输入时，这很容易:

I'm creating the user object in my html, every field had an ng-model binded to some property of the user. When i'm using simple input such as firstName then it's easy:

<input class="form-control" type="text" name="firstName" ng-model="user.firstName"/>

但是随着下拉菜单 -我希望国家名称显示在下拉列表选项中，并将其代码放置在用户对象中.我想避免为此在控制器中编写代码.(即 $scope.user.countryCode = $scope.country.selected.code; )

But with the dropdown - I want the country name to be displayed in the dropdown list options and the its code to be placed in the user object. I want to avoid writing code in the controller for this. (i.e. $scope.user.countryCode = $scope.country.selected.code; )

推荐答案

我认为你可以:

<ui-select-choices repeat="country.code as country in countries">
    <span ng-bind-html="country.name | highlight: $select.search"></span>
</ui-select-choices>

来自文档:https://github.com/angular-ui/ui-select/wiki/ui-select-choices

在重复的 ui-select-choices 中标识您要绑定到的属性；repeat="item.id as item in card">.

In the repeat of the ui-select-choices identify the property you are wanting to bind to; repeat="item.id as item in cards">.
