问题是关于事件mouseenter被触发两次。 代码在这里: jsfiddle/xyrhacom/
The problem is about event mouseenter which is triggered twice. The code is here : jsfiddle/xyrhacom/
HTML:
<div id="elt1" class="elt" val="text1"> text1 <div id="elt2" class="elt" val="text2"> text2 <div> </div>JS:
$(document).ready(function() { $(".elt").mouseenter(function() { console.log($(this).attr('val')); }); })问题是事件链接到类属性,所以它被触发为每个类,但我需要找到一种方式来考虑只是为孩子触发的事件。
I understand the problem is the event is linked to the class attribute so it is triggered for each class, but I need to find a way to consider just the event triggered for the child.
在示例中,当鼠标悬停text2时,它显示在控制台text2 text1中,但是我想要找到一种只显示text2(保持相同的HTML代码)的方式
In the example, when mouseover text2, it displays in the console 'text2 text1' but I want to find a way to only display 'text2' (keeping the same HTML code)
推荐答案使用 stopPropagation() ;防止事件冒泡DOM树,
use stopPropagation(); Prevents the event from bubbling up the DOM tree,
$(document).ready(function() { $(".elt").mouseenter(function(e) { e.stopPropagation(); console.log($(this).attr('val')); }); })更多推荐
