我有一个这样的div标签:
<div>
<label>Name</label>
<input type="text"/>
</div>
我如何显示一个工具提示:div的悬停，最好有一个淡入/淡出效果。

我开发了三种类型的褪色效果:
/* setup tooltips */ .tooltip { position: relative; } .tooltip:before, .tooltip:after { display: block; opacity: 0; pointer-events: none; position: absolute; } .tooltip:after { border-right: 6px solid transparent; border-bottom: 6px solid rgba(0,0,0,.75); border-left: 6px solid transparent; content: ''; height: 0; top: 20px; left: 20px; width: 0; } .tooltip:before { background: rgba(0,0,0,.75); border-radius: 2px; color: #fff; content: attr(data-title); font-size: 14px; padding: 6px 10px; top: 26px; white-space: nowrap; } /* the animations */ /* fade */ .tooltip.fade:after, .tooltip.fade:before { transform: translate3d(0,-10px,0); transition: all .15s ease-in-out; } .tooltip.fade:hover:after, .tooltip.fade:hover:before { opacity: 1; transform: translate3d(0,0,0); } /* expand */ .tooltip.expand:before { transform: scale3d(.2,.2,1); transition: all .2s ease-in-out; } .tooltip.expand:after { transform: translate3d(0,6px,0); transition: all .1s ease-in-out; } .tooltip.expand:hover:before, .tooltip.expand:hover:after { opacity: 1; transform: scale3d(1,1,1); } .tooltip.expand:hover:after { transition: all .2s .1s ease-in-out; } /* swing */ .tooltip.swing:before, .tooltip.swing:after { transform: translate3d(0,30px,0) rotate3d(0,0,1,60deg); transform-origin: 0 0; transition: transform .15s ease-in-out, opacity .2s; } .tooltip.swing:after { transform: translate3d(0,60px,0); transition: transform .15s ease-in-out, opacity .2s; } .tooltip.swing:hover:before, .tooltip.swing:hover:after { opacity: 1; transform: translate3d(0,0,0) rotate3d(1,1,1,0deg); } /* basic styling: has nothing to do with tooltips: */ h1 { padding-left: 50px; } ul { margin-bottom: 40px; } li { cursor: pointer; display: inline-block; padding: 0 10px; } <h1>FADE</h1> <div class="tooltip fade" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div> <h1>EXPAND</h1> <div class="tooltip expand" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div> <h1>SWING</h1> <div class="tooltip swing" data-title="Hypertext Markup Language"> <label>Name</label> <input type="text"/> </div>

您还可以自定义工具提示样式。请参阅此连结: http://jqueryui.com/tooltip/#custom-style
下面是一个简单的工具提示实现，它可以考虑鼠标的位置以及窗口的高度和宽度:
function showTooltip(e) { var tooltip = e.target.classList.contains("tooltip") ? e.target : e.target.querySelector(":scope .tooltip"); tooltip.style.left = (e.pageX + tooltip.clientWidth + 10 < document.body.clientWidth) ? (e.pageX + 10 + "px") : (document.body.clientWidth + 5 - tooltip.clientWidth + "px"); tooltip.style.top = (e.pageY + tooltip.clientHeight + 10 < document.body.clientHeight) ? (e.pageY + 10 + "px") : (document.body.clientHeight + 5 - tooltip.clientHeight + "px"); } var tooltips = document.querySelectorAll('.couponcode'); for(var i = 0; i < tooltips.length; i++) { tooltips[i].addEventListener('mousemove', showTooltip); } .couponcode { color: red; cursor: pointer; } .couponcode:hover .tooltip { display: block; } .tooltip { position: absolute; white-space: nowrap; display: none; background: #ffffcc; border: 1px solid black; padding: 5px; z-index: 1000; color: black; } Lorem ipsum dolor sit amet, <span class="couponcode">consectetur adipiscing<span class="tooltip">This is a tooltip</span></span> elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in <span class="couponcode">reprehenderit<span class="tooltip">This is another tooltip</span></span> in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est <span class="couponcode">laborum<span class="tooltip">This is yet another tooltip</span></span>.

对于基本的工具提示，您需要:
<div title="This is my tooltip">
如:
.visible { 高度:3他们; 宽度:10 em; 背景:黄色; } <div title="This is my tooltip" class="visible"></div> .
对于一个更花哨的javascript版本，你可以查看:
https://jqueryhouse.com/best-jquery-tooltip-plugins/
上面的链接提供了25个工具提示选项。
不使用任何API 你也可以通过使用纯CSS和Jquery演示来做这样的事情
HTML
<div class="pointer_tooltip">
Click & Drag to draw the area
</div>
CSS
.pointer_tooltip{
width : auto;
height : auto;
padding : 10px;
border-radius : 5px;
background-color : #fff;
position: absolute;
}
Jquery
$(document).mousemove(function( event ) {
var pageCoords = "( " + event.pageX + ", " + event.pageY + " )";
//set the actuall width
$('.pointer_tooltip').width($('.pointer_tooltip').width());
var position_top = event.pageY+18;
var position_left = event.pageX-60;
var width=$('body').width()-$('.pointer_tooltip').width();
//check if left not minus
if(position_left<0){
position_left=10;
}else if(position_left > width){
position_left=width-10;
}
$('.pointer_tooltip').css('top',position_top+'px');
$('.pointer_tooltip').css('left',position_left+'px');
});
试试这个。你可以这样做，只有css和我只添加了数据标题属性的工具提示。
.tooltip { 位置:相对; 显示:inline-block; ｝ .tooltip [data-title]:徘徊:{后 内容:attr (data-title); 填充:4px 8px; 颜色:# fff; 位置:绝对的; 左:0; 上图:110%; 空白:nowrap;} border - radius: 5 px; 背景:# 000; ｝ <div data-title="My tooltip" class="tooltip"> < >标签名称> < /标签 < input type = " text " / > < / div >
