Question

我的ng-model值不适用于ng-if下的复选框，但值存在。它只在双击时才会更新。

<div ng-show="isTrue == true">
<label>
  <input type="checkbox" name="test1" ng-model="a.testModel[0]" ng-true-value="1" ng-false-value="0" /> Testing 1 {{a.testModel[0]}}</label>
<br />
<label>
  <input type="checkbox" name="test2" ng-model="a.testModel[1]" ng-true-value="1" ng-false-value="0" /> Testing 2</label>
<br />
<label>
  <input type="checkbox" name="test3" ng-model="a.testModel[2]" ng-true-value="1" ng-false-value="0" /> Testing 3</label>
<br />
<input type="button" ng-click="submit()" value="Submit" />

这里你应该使用ng-true-value和ng-false-value的字符串值作为ng-true-value="'1'" ng-false-vale="'0'"，因为你的数组将值存储为字符串..

Answer 2

ng-true-value | ng-false-value应定义为String

 ng-true-value="'1'" ng-false-value="'0'"
