javascript - 无法在 ngRepeat 中使用 ngChange - Angularjs

Question

我正在使用 ngRepeat 生成一个复选框字段集。

我是这样做的:

<fieldset id="country_select" ng-controller="CountriesListController">
        <span ng-repeat="country in countries">
          <label>
            <input type="checkbox" id="country.name" ng-change="locationAdd(country.name)">
            {{country.name}}
          </label><br/>
        </span>
</fieldset>

但是由于某种原因，将 ngChange 指令添加到我的复选框会导致我的 ng-repeat 输出仅显示一个复选框，如下所示:

复选框 {{country.name}}

当我将 ngChange 更改为 ngClick 时，我的 ngRepeat 循环起作用了。

所以我的问题是:为什么 ngChange 不能与 ngRepeat 一起使用，但 ngClick 在插入我的复选框输入时可以使用

我的控制台出现以下错误:

Answer 1

ng-change 需要 ng-model。您在复选框上缺少 ng-model
