这是我尝试运行的代码演示,我的原始代码包含 js 文件,该文件使用 innerHTML 函数动态填充我的 ul 类,但输出与我提供的虚拟列表数据相同。

我不明白为什么我的列表标签不起作用。我尝试使用本网站提供的其他答案来解决它,检查 z 索引以及 a 和 li 标签的绝对和相对位置。

最佳答案

原因是因为在点击时,input失去了它的:focus(正如shaochuancs所指出的) ) 并且在注册 anchor 点击之前隐藏内容。 click 事件由 mousedown mouseup 事件组成。失去焦点是在页面上的任何位置 mousedown 触发的。因此,只需防止 :focus 在 anchor 标记上的 mousedown 上丢失。其余代码将按预期运行,因为 anchor 标记点击是在 mouseup 上触发的。

所以这个问题可以用一些基本的 javascript/jQuery 来处理,只需在 anchor 标签上 mousedownpreventDefault() 即可。

$("a").mousedown(function(ev) {
ev.preventDefault();
}

请注意,在此代码片段中,链接未加载,因为它被框架阻止了。但是你可以在控制台看到链接被点击了。

$("a").mousedown(function(ev) {
ev.preventDefault();
console.log($(this).attr("href"));
console.log("Click triggered");
});
