单击链接时如何使用 jQuery 发出警报？

Question

I want to alert something if a <a> is clicked, but only if there is a real link. I have this code but it doesn't really work...

$("a").click(function(){
    if ($(this).attr("href") != "#" && $(this).attr("href") != "") {
        alert("foo");
    }
});

What is wrong?

Thanks

Make sure you're calling e.preventDefault() in the method.

$("a").click(function(e){
    if ($(this).attr("href") != "#" && $(this).attr("href") != "") {
        alert("foo");
        e.preventDefault();
    }
});
