选择框中的Angular，boolean值

问题描述

我想使用select将布尔值设置为true或false这是我的代码：

I want to set a boolean value to true or false using a select here is my code:

<select class="span9" ng-model="proposal.formalStoryboard">
<option value="false">Not Included</option>
<option value="true">Included</option>
</select>

值（proposal.formalStoryboard）正确设置为true或false 但更改为当值已经分配时，没有反映在选择框上。

The value (proposal.formalStoryboard) is set properly to true or false but the change are not reflected on the select box when the value is already assigned.

我试过ng-value =true和ng-value =false代替只是价值，但它不能正常工作。

I tried ng-value="true" and ng-value="false" instead of just value but it's not working as well.

Commentors have pointed out that my original solution did not work as claimed. I have updated the answer to reflect the correct answer given by others below (I cannot delete an accepted answer).

对于Angular 1.0.6，请考虑以下HTML：

For Angular 1.0.6, consider this HTML:

<div ng-app="">
  <div ng-controller="MyCntrl">
    <select ng-model="mybool"
            ng-options="o.v as o.n for o in [{ n: 'Not included', v: false }, { n: 'Included', v: true }]">
    </select>
    <p>
        Currently selected: <b>{{ mybool }}</b> opposite: {{ !mybool }}
   </p>
 </div>
</div>

这个JavaScript：

And this JavaScript:

function MyCntrl($scope) {
    $scope.mybool = true;
}

这是一个工作，这是一个适用于Angular的 1.3.14，略有不同。

Here is a working DEMO for Angular 1.0.6 and here is a working DEMO for Angular 1.3.14, which is slightly different.
