![选择框中的角度]( "选择框中的角度")
本文介绍了选择框中的角度、布尔值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想使用选择将布尔值设置为 true 或 false 这里是我的代码:
<option value="false">不包括</option><option value="true">包含</option></选择>
值 (proposal.formalStoryboard) 被正确设置为 true 或 false 但是当已经分配了值时，更改不会反映在选择框中.
我尝试了 ng-value="true" 和 ng-value="false" 而不仅仅是 value，但效果不佳.
解决方案
评论者指出我原来的解决方案没有像声称的那样工作.我已更新答案以反映以下其他人给出的正确答案(我无法删除已接受的答案).
对于 Angular 1.0.6，请考虑以下 HTML:
<div ng-controller="MyCntrl"><选择 ng-model="mybool"ng-options="o.v as o.n for o in [{ n: 'Not Included', v: false }, { n: 'Included', v: true }]"></选择><p>当前选择:<b>{{mybool }}</b>对面:{{ !mybool }}</p>
还有这个 JavaScript:
function MyCntrl($scope) {$scope.mybool = true;}
这是一个适用于 Angular 1.0.6 的 DEMO，这是一个有效的 DEMO for Angular 1.3.14，略有不同.
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>
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.
I tried ng-value="true" and ng-value="false" instead of just value but it's not working as well.
解决方案
EDIT: 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).
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>
And this JavaScript:
function MyCntrl($scope) {
$scope.mybool = true;
}
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.
