Dom 使用JQuery event.target处理子项
我的问题特别提到 如果像我所做的那样，在Dom 使用JQuery event.target处理子项,dom,jquery,Dom,Jquery,我的问题特别提到 如果像我所做的那样，在或其他标记中使用span来更改样式，例如，元素的该部分将不会触发JQuery函数切换其子元素。如何才能让这一切顺利进行 HTML: 要继续使用当前表单，我建议使用closest（）： 虽然我自己喜欢： $('li').on('click', function(e){ e.stopPropagation(); $(this).find('ul').toggle(); }); 参考资料： 一个完整的e.target子项示例，与dat
要继续使用当前表单，我建议使用
closest（）$('li').on('click', function(e){
e.stopPropagation();
$(this).find('ul').toggle();
});
真的不客气，我很高兴能帮上忙！=）太棒了，大卫！第二种解决方案很酷很简单。谢谢你的小提琴！不错！我使用您的方法来验证todo列表中单击的胶粘物类：$target_class=$target.find（'a'）；var targ_class=$target_class.attr（'class'）；如果（targ_类=='mynote'）。。。。否则……应谨慎使用停止事件传播：
function handler(event) {
var $target = $(event.target);
if( $target.is("li") ) {
$target.children("ul").toggle();
}
}
$("ul").click(handler).find("ul").hide();
function handler(event) {
$(event.target).closest('li').children("ul").toggle();
}
$("ul").click(handler).find("ul").hide();
$('li').on('click', function(e){
e.stopPropagation();
$(this).find('ul').toggle();
});
