angularjs類型錯誤：布爾不是一個函數NG單擊多個動作

Question

當試圖做到這一點：

<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) 

應該如何我寫這是否正確？

Answer 1

如果沒有必要，我不會在你的視圖中放太多東西。創建一個函數並傳遞你需要的東西並從那裏進行評估。

此外，

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

這看起來像一個錯誤的三元操作如果這是你想要做什麼？

如果正確地明白：

如果answer.Questions.length> 0，則（setAnswer（問題，answer.ID）），如果不是setAnswer（問題，answer.ID）。

這是什麼一部分

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

？

也許你想要的東西，像

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