我正在构建一个测验，其中有两个选项可以回答问题，滑动(向右或向左)或单击(心形或划掉心形)选项。
我可以使用滑动功能并正确地制表分数，但我无法让点击事件运行用于计算答案是否正确的参数。
我的 HTML 看起来像这样:

我只想让点击事件运行参数以确定答案是否正确。
例如，当用户向右滑动时运行此参数的当前脚本片段如下所示:
$scope.cardSwipedRight = function(index) {
console.log('RIGHT SWIPE');
var card = $scope.cards.active[index];
$scope.cards.liked.push(card);
var givenAnswer = 1,
correctAnswer = card.valid;
if (givenAnswer === correctAnswer) {
console.log('correct!!!!');
} else {
console.log('incorrect!!!!');
}
//increment the points variable if the answer is correct:
if (givenAnswer === correctAnswer) {
console.log('correct!!!!');
$scope.points++;
}
};
最佳答案
来自HTML spec :
When the user agent leaves the attribute name state (and before emitting the tag token, if appropriate), the complete attribute's name must be compared to the other attributes on the same token; if there is already an attribute on the token with the exact same name, then this is a parse error and the new attribute must be removed from the token.
意思是，当你写的时候:
<div class="no-text" ng-click="onClickTransitionOut(card)($index)" ng-click="onClickNotFamily(card)($index)"></div>
第一个ng-click属性 ( onClickTransitionOut... ) 被分配，第二个 ( onClickNotFamily ) 被丢弃，因为 ng-click 已经有值了.因此，只有第一个函数会在您单击时运行。
这里有两个选项可以解决这个问题，以便运行两个函数:
重构您的代码，以便有一个函数可以绑定(bind)到
ng-click.我建议这样做，因为您的 JS 似乎在点击和滑动处理程序之间有一些复制/粘贴代码。合并
ng-click属性为ng-click="function1(); function2()"(如 this post 中所示)。
希望对您有所帮助!我不是 Angular 专家，所以可能还有其他我没有注意到的问题。
