   <input ng-model="disName" type="text">

这是对象数组中的特定对象。如何为假设[key = Display Name]的键修改特定的值，并随着输入值的更改如何在对象中对其进行修改？

在angularJS中，您将使用<script src="https://www.amcharts.com/lib/4/core.js"></script> <script src="https://www.amcharts.com/lib/4/charts.js"></script> <div id="chartdiv"></div>将object属性绑定到输入。无需聆听任何更改，因为该框架会处理这些更改。

¿谁将这个对象提供给ng-model？控制器，通过<input>公开对象。

这是使用this的有效示例。

如您所见，由于对象键上使用了空格，因此需要使用括号符号。

components

在一个真实的示例中，我想您的<input ng-model="$ctrl.obj['Display Name']">将通过服务提供，如您在本示例中看到的那样：
