锚标记在列表项内不起作用

时间:2017-06-27 06:38:32

标签: javascript html css html-lists anchor

put "/products/:id"

这是我试图运行的代码的演示,我的原始代码包含js文件,它使用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。

我无法理解为什么我的列表标记不起作用。我试图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。

根本原因是:点击锚标记后,.search input会失去:focus状态,这会导致.search input:focus + .results { display: block }停用,.search .results会{{1}再次作为display - 由于页面上不再存在none标记,因此没有任何反应。它与<a>ul无关。

以下是一个简化示例:https://jsfiddle.net/cshao/rtonLr4z/li赢得了问题。

答案 1 :(得分:3)

原因是因为在click上,input丢失了:focus(正如 shaochuancs 所指出的那样)并且内容在点击之前被隐藏锚已注册。 click活动包含mousedown mouseup活动。在页面的任何位置mousedown都会触发失去焦点。因此,只需防止锚标记:focus上的mousedown丢失。其余代码将按预期运行,因为锚点标记点击是在mouseup上触发的。

所以问题可以通过一些基本的javascript / jQuery来处理,只需preventDefault()mousedown锚标签上即可。

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

请注意,在此代码段中,链接未加载,因为它被框架阻止。但是你可以在控制台中看到点击链接。

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

还有另一种可能性。如果将锚点的装饰设置为无,并在悬停Achor链接时更改li的背景,则仅当您将鼠标悬停在锚点的文本上时,该锚点才起作用,但是您想要的是,锚点会在li的整个表面上激活,但是如何进行这项工作是另一回事。
