Get ID of the element I hover over with jQuery?
提问by Andrew
I have a bunch of elements that look like this:
我有一堆看起来像这样的元素：
<span class='tags' id='html'>html</span>
<span class='tags' id='php'>php</span>
<span class='tags' id='sql'>sql</span>
How would I get the name of the id of the one I hover over, so I could output something like "You're hovering over the htmltag". (What I want to do isn't that arbitrary, but I do need to get the name of the tag the user hovers over in order to do it.)
我如何获得我悬停的那个 ID 的名称，以便我可以输出类似“你悬停在html标签上”的内容。（我想做的并不是那么随意，但我确实需要获取用户悬停在其上的标签名称才能做到这一点。）

$('.tags').hover(
function() { console.log( 'hovering on' , $(this).attr('id') ); },
function() {}
);
Second empty function is for mouse out, you'll probably want to do something on that event as well.
第二个空函数用于鼠标移出，您可能还想在该事件上做一些事情。

Use this one:-
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("p").hover(function(){
//if get onhover id
alert("NOW GET ON HOVER ID NAME:--"+" "+this.id);
//if get onhover class
alert("NOW GET ON HOVER CLASS NAME:--"+" "+$(this).attr('class'));
});
});
</script>
</head>
<body>
<p class="getclass" id="get_class_id" >Hover the mouse</p>
</body>

These solutions still returned an empty alert for me. For me, following worked when I handled the event object passed to the hover function:
这些解决方案仍然为我返回了一个空警报。对我来说，当我处理传递给悬停函数的事件对象时，以下工作：
$(".input-box").hover(function(eventObj) {
alert(eventObj.target.id);
});
