如何将所选颜色绑定到 ng-model？

Scrumnoob

我在我的程序中添加了一个颜色选择器，我正在尝试将所选颜色绑定到所选形状。我试图得到它，以便我选择的颜色改变单元格的颜色。{{userSelect}} 是包含所选形状的元素的名称。

HTML 实体需要以分号结尾 (;)

使用ng-style指令设置颜色。

.shape {
   font-size: 30px;
   color: green;
}

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app ng-init="userSelect='&#9632;'">
      <input type="color" ng-model="userColor">Pick color {{userColor}}<br>
      <select ng-model="userSelect">
          <option value="&#9679;">Circle</option>
          <option value="&#9632;">Square</option>
          <option value="&#9650;">Triangle</option>
      </select>
      <br>
      userSelect=
      <span class="shape" ng-style="{'color':userColor}">{{userSelect}}</span>
  </body>
