javascript - Angular 错误: $parse:ueoe Unexpected End of Expression for a couple of expressions

Question

以下两个表达式引发错误:

ng-click="vm.numOthersAttending++"
ng-click="vm.numOthersAttending = vm.numOthersAttending > 0 ? vm.numOthersAttending - 1 : 0"

我不能在 ngClick 中放入任何表达式进行评估吗？

Answer 1

<div ng-click="vm.numOthersAttending = vm.numOthersAttending + 1">click</div>
<div ng-click="vm.numOthersAttending = (vm.numOthersAttending > 0) ? (vm.numOthersAttending - 1) : 0">click</div>

一般来说，使用函数更好。
