问题描述
这里是堆栈溢出的菜鸟.我正在处理一个具有转移工作功能的网页.这使用户可以选中复选框以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,以便在页面加载时默认选中它并相应地禁用选择列表.这是我目前拥有的代码:
发送到办公室:<input type="checkbox" ng-model="checked" ng-checked="true"><br/><select id="transferTo" ng-disabled="checked"><option>Tech1</option><option>Tech2</option></选择>
这里是一个 jsfiddle:http://jsfiddle.net/hugmungus/LvHJw/5/
当前,页面加载时选中了复选框,但列表未禁用.如果您取消选中然后重新选中它,该列表将被禁用.
感谢您的帮助!
如果你使用 ng-model,你不想也使用 ng-checked.相反,只需将模型变量初始化为 true.通常,您会在管理页面的控制器中执行此操作(添加一个). 在您的小提琴中,我只是出于演示目的在 ng-init 属性中进行了初始化.
发送到办公室:<input type="checkbox" ng-model="checked" ng-init="checked=true"><br/><select id="transferTo" ng-disabled="checked"><option>Tech1</option><option>Tech2</option></选择>
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>
and here is a jsfiddle for it: http://jsfiddle.net/hugmungus/LvHJw/5/
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.
Thanks for the help!
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>
