将onClick事件触发到特定的div

Question

我有两张卡片，如果用户单击“赞”按钮（心形图标），则会触发onClick()事件以在卡片图像上方创建调光器。 我正在尝试在用户单击心脏图标的卡片图像上创建调光器。

我试图提出一个条件：

if (e.target !== this)
    return;

但这没有用。 在真实的网页中，我会看到一串没有标识符的卡片，可以在其中指定要变暗的图像。 在这种情况下可以吗？

更新小提琴 。

你应该使用当前的点击jQuery对象$(this) ，而不是为目标的相关.imglove在同一.card ：

$(this).closest('.card').find('.imglove').dimmer('show');

注意： .closest('.card')用于获取带有单击图标loveit的相关card 。

希望这可以帮助。

 $(function() { $(document).on('click', '.loveit', function(e) { e.preventDefault(); $(this).closest('.card').find('.imglove').dimmer('show'); }); });

因此，您正在尝试将交互仅限于当前选择的图像吗？ 另外，不要引用小提琴，而是在此处发布您的工作（或非工作）代码。 各地都比较容易。

 jQuery(document).ready(function($) { $(document).on('click', '.loveit', function(e) { e.preventDefault(); $(this).parents(".card").find('.imglove') .dimmer('show'); }); });

使用课程card将其定位parent对象，然后find课程imglove并imglove添加dimmer

 jQuery(document).ready(function($) {
   $(document).on('click', '.loveit', function(e) {
     $(this).parents('.card').find('.imglove').dimmer('show');
    });
 });
