这是我要运行的代码的演示，我的原始代码包含js文件，该文件使用innerHTML函数动态填充ul类，但输出与我提供的伪列表数据相同.
This is a demo of the code that I am trying to run , my original code contains js file which is dynamically populating my ul class using the innerHTML function but the output is same as the dummy list data I have provided.
我无法理解为什么我的列表标签不起作用.我尝试使用此站点上提供的其他答案来解决该问题，检查z索引以及a和li标签的绝对位置和相对位置.
I am not able to understand why my list tag does not work . I have tried to resolve it using other answers provided on this site , checking for z index and absolute and relative position of a and li tag.
推荐答案
原因是因为在click上，input失去了:focus(如 shaochuancs 所指出)，并且在点击锚点之前，该内容是隐藏的. click事件由mousedown 和 mouseup事件组成.焦点丢失在页面上任何位置的mousedown上触发.因此，只需防止锚标记的mousedown上的:focus丢失.其余代码将按预期运行，因为在mouseup上触发了锚标记单击.
The reason is because on click, the input loses its :focus (as pointed out by shaochuancs) and the content is hidden before the click on the anchor is registered. A click event consists of mousedown and mouseup event. The loss of focus is triggered on mousedown anywhere on the page. So just prevent the loss of :focus on mousedown on the anchor tags. The rest of the code would function as expected, because the anchor tag click is triggered on mouseup.
因此，只需在锚标签上的mousedown上的preventDefault()即可使用一些基本的javascript/jQuery处理该问题.
So the issue can be dealt with some basic javascript/jQuery, by simply preventDefault() on mousedown on the anchor tags.
$("a").mousedown(function(ev) {
ev.preventDefault();
}
请注意，在此代码段中，链接不被加载，因为它被框架阻塞了.但是您可以在控制台中看到单击了链接.
Note that in this code snippet the link doesn't load because it is blocked by the frame. But you can see in the console that the link is clicked.
$("a").mousedown(function(ev) {
ev.preventDefault();
console.log($(this).attr("href"));
console.log("Click triggered");
});
