就这么简单,我正在使用带有哈希标签和网址的菜单栏......
HTML: -
<ul class="nav">
<li class="active"><a href="#firstpage">home</a></li>
<li><a href="demo.html">Demo</a></li>
<li><a href="#secondpage">second</a></li>
<li><a href="#thirdpage">third</a></li>
<li><a href="#fourthpage">fourth</a></li>
<li><a href="">fifth</a></li>
<li><a href="mailto:abc@xyz.com">Email</a></li>
<li><a href="tel:+000">Phone</a></li>
<li><a href="#">last</a></li>
</ul>
我希望有一个代码可以在点击哈希锚点或网址锚点时发出警告?
这样的事情: -
if("anchor has a hash") { alert("It is a hash"); }
else if("anchor has a url") { alert("It is a url"); }
else if("anchor has a email") { alert("It is a email"); }
else if("anchor has a phone number") { alert("It is a phone number"); }
else { alert("Its empty") }
我所提到的this但是找不到确切的解决方案?

这应该有帮助
$(".nav a").on("click", function(event) {
var href = $(this).attr("href");
if (href.indexOf("#") !== -1) {
alert("hashtag");
}
else if (href.length > 0) {
alert("has a url");
}
else {
alert("blank");
}
});
