Question

我已经为一个名为

的对象分配了一个数组

processMapAttrib.auditNotifyUsers.unAssignedUsers

当我使用

在HTML文件中打印变量时

<label>{{processMapAttrib.auditNotifyUsers.unAssignedUsers}}</label>

我得到了

[{"id":230,"name":"Parthiban V"},{"id":231,"name":"Kanna A"},{"id":252,"name":"jagadesh S"},{"id":253,"name":"saravana kumar"},{"id":346,"name":"sith user"},{"id":347,"name":"seventh user"},{"id":348,"name":"unlimited user"}]

processMapAttrib也有其他值。比如processMapAttrib.Process = {}，processMapAttrib.task = {}，......

但是当我在ng-repeat中使用它时，它就不起作用了。

<select multiple="multiple">
    <option value="{{list.id}}" ng-repeat="list in processMapAttrib.auditNotifyUsers.unAssignedUsers">{{list.name}}</option>
</select>

请帮助我将数据填充到选择选项中。

我建议您使用NgOptions代替NgRepeat，易于使用，并且是一个很好的指令，可以在select元素中动态生成选项元素列表

将此添加到您的视图

最后我在代码中发现了问题。我已将value属性更改为ng-value。它的工作正常。

 <option ng-value="list.id" ng-repeat="list in processMapAttrib.auditNotifyUsers.unAssignedUsers">{{list.name}}</option>

试试这段代码：

var app = angular.module("myApp", [])
app.controller("myCtrl", function ($scope) {
    $scope.processMapAttrib = [{
        "id": 230,
        "name": "Parthiban V"
    }, {
        "id": 231,
        "name": "Kanna A"
    }, {
        "id": 252,
        "name": "jagadesh S"
    }, {
        "id": 253,
        "name": "saravana kumar"
    }, {
        "id": 346,
        "name": "sith user"
    }, {
        "id": 347,
        "name": "seventh user"
    }, {
        "id": 348,
        "name": "unlimited user"
    }]
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
    <label>{{processMapAttrib}}</label>
    <select multiple="multiple">
        <option value="{{list.id}}" ng-repeat="list in processMapAttrib">{{list.name}}</option>
    </select>
</div>

AngularJS ng-repeat不使用选择选项
