angularjs typeError: boolean is not a function ng-click multiple actions

Question

尝试实现此目的时：

<li class="answer"><a href="javascript:void(0)" ng-class="answer.show[$index] ? 'selected' : ''" ng-click="(answer.Questions.length > 0) ? (answer.show[$index]=!answer.show[$index]) (setAnswer(question, answer.ID)) : setAnswer(question, answer.ID)">{{answer.Description}}</a></li>

The problem is on my ng-click:

(answer.Questions.length > 0) ? (answer.show[$index]=!answer.show[$index]) (setAnswer(question, answer.ID)) : setAnswer(question, answer.ID)

这个应该怎么写才正确？

Answer 1

如果没有必要，我不会在您的视图中放那么多东西。创建一个函数并传递您需要的东西并从那里进行评估。

此外，

ng-click="(answer.Questions.length > 0) ? (answer.show[$index]=!answer.show[$index]) (setAnswer(question, answer.ID)) : setAnswer(question, answer.ID)"

这看起来像一个错误的三元运算，如果这是你想要做的？

如果我理解正确的话：

if answer.Questions.length > 0，则 (setAnswer(question, answer.ID))，如果不是 setAnswer(question, answer.ID)。

这部分是做什么用的

(answer.show[$index]=!answer.show[$index])

?

也许你想要这样的东西

((answer.Questions.length > 0) && (answer.show[$index]=!answer.show[$index])) ? (setAnswer(question, answer.ID)) : setAnswer(question, answer.ID)
