我的问题专门针对http://api.jquery.com/event.target/#example-1
如果您使用<li>或其他标记中的范围来更改<b>之类的样式（我已完成here），则该元素的该部分将不会触发JQuery功能切换它的孩子。怎么可能让这个工作？
HTML：
<ul>
<li><b>This doesn't work,</b> this does
<ul>
<li>sub item 1-a</li>
<li>sub item 1-b</li>
</ul>
</li>
<li>item 2
<ul>
<li>sub item 2-a</li>
<li>sub item 2-b</li>
</ul>
</li>
</ul>
JavaScript的：
function handler(event) {
var $target = $(event.target);
if( $target.is("li") ) {
$target.children("ul").toggle();
}
}
$("ul").click(handler).find("ul").hide();
答案 0 :(得分：10)
要继续使用您当前的表单，我建议您使用closest()：
function handler(event) {
$(event.target).closest('li').children("ul").toggle();
}
$("ul").click(handler).find("ul").hide();
虽然我自己使用，但我更喜欢：
$('li').on('click', function(e){
e.stopPropagation();
$(this).find('ul').toggle();
});

e.target子项的完整示例，最接近数据表和外部数据。
