Question

我在AngularJS中生成动态表单：

<div ng-repeat="choice in myData" class='repeater'>
    <div ng-if="choice.type === 'dropdown'" ng-init="count = 0">
        <div class="row">
            <div class="col-md-2">
                <p>choose</p>
            </div>
            <div class="col-md-8">
                <select ng-model="selected" ng-options="item.value for item in mydatedropdown[count]"> </select>
            </div>
        </div>
        {{count += 1}}
    </div>
</div>

我无法增加count的值并将其分配给mydatedropdown[]。我是AngularJS的新手。

您可以尝试将ng-repeat更改为<div ng-repeat="(index, choice) in myData" class='repeater'>并使用index中的mydatedropdown

<div ng-repeat="(index, choice) in myData" class='repeater'>
    <div ng-if="choice.type === 'dropdown'" ng-init="count = 0">
        <div class="row">
            <div class="col-md-2">
                <p>choose</p>
            </div>
            <div class="col-md-8">
                <select ng-model="selected" ng-options="item.value for item in mydatedropdown[index]"> </select>
            </div>
        </div>
    </div>
</div>

ng-if在angularjs中的ng-repeat内
