Question

我有一个包含选择框的表格数据。我想使用ng-model而不是{{n.triggerOn}来绑定数据。当我使用log时，以下代码正常工作。但我想使用ng -model <option value="">{{n.triggerOn}}</option>

绑定数据

<option ng-model="n.triggerOn"></option>

我以JSON格式获取数据

                <td>
                    <select class="browser-default event trigger">
                        <option value="">{{n.triggerOn}}</option>
                        <option value="all">
                            All Conditions
                        </option>
                        <option value="any">
                            Any Conditions
                        </option>
                    </select>
                </td>

任何人都可以帮助我吗？我是angularjs的新手。对不起，如果这是一个愚蠢的错误。三江源。

Answer 1

在select标签中使用ngmodel属性，在选项而不是值使用ng-value中，告诉我它是否无效。

这是工作代码

        $scope.rules = [

您需要在布尔值中再发送一个名为selected的变量。

 $scope.rules = [
      {name:"abc", status:"enable", triggerOn: "none", onSuccess: "on", selected: false },
      {name:"abc", status:"enable", triggerOn: "any", onSuccess: "on", selected: true},
      {name:"abc", status:"enable", triggerOn: "all", onSuccess: "on", selected: false }
    ];

然后在html

中绑定ng-selected attr

<option ng-repeat="rule in rules" value="{{rule.triggerOn}}"
                    ng-selected="{{ rule.selected == true }}">

如何在angularjs中的选择框或内部选项中使用ng-model？
