在加载时默认选中Angularjs复选框，并在选中时禁用选择列表 [英] Angularjs checkbox checked by default on load and disables Select list when checked

问题描述

noob on stack overflow here。我正在处理一个具有转移工作功能的网页。这允许用户选中复选框将作业发送回办公室，或从所有可用的列表中选择技术人员。我的问题是如何设置复选框，以便在默认情况下检查页面加载并相应地禁用选择列表。这里是我目前的代码：

noob on stack overflow here. I am working on a webpage that has a transfer job function. This lets the user check a check-box to send the job back to the office, or select a technician from a list of all that are available. My question is how to setup the check-box so that it is checked by default when the page loads and have the select list disabled accordingly. Here is the code that I have for it at the moment:

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-checked="true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>

这里是一个jsfiddle它： http://jsfiddle.net/hugmungus/LvHJw/5/

and here is a jsfiddle for it: http://jsfiddle.net/hugmungus/LvHJw/5/

目前，框已选中，但列表未禁用。

Currently, the page loads with the check-box checked, but the list is not disabled. If you un-check then re-check the it, the list becomes disabled.

感谢您的帮助！

推荐答案

如果你使用ng-model，你不想使用ng-checked。而只是将模型变量初始化为true。通常你可以在一个控制器中管理页面（添加一个）。在你的小提琴中，我只是在ng-init属性中进行初始化以进行演示。

If you use ng-model, you don't want to also use ng-checked. Instead just initialize the model variable to true. Normally you would do this in a controller that is managing your page (add one). In your fiddle I just did the initialization in an ng-init attribute for demonstration purposes.

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-init="checked=true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>
