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。

工具提示定位纯css
div { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); -ms-transform: translate(-50%, -50%); /* IE 9 */ -webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */ text-align: center; } .tooltip { position: relative; display: inline-block; border-bottom: 1px dotted black; } .tooltip .tooltiptext { visibility: hidden; width: 120px; background-color: black; color: #fff; //text-align: center; border-radius: 6px; padding: 5px 0; /* Position the tooltip */ position: absolute; z-index: 1; } .tooltip:hover .tooltiptext { visibility: visible; } .toolLeft { top: -5px; right: 105%; } .toolRight { top: -5px; left: 105%; } .toolTop { bottom: 100%; left: 50%; margin-left: -60px; } .toolBottom { top: 100%; left: 50%; margin-left: -60px; } <div> <div class="tooltip">Top <span class="tooltiptext toolTop">Tooltip text</span></div><br /> <div class="tooltip">Left <span class="tooltiptext toolLeft">Tooltip text</span></div><br /> <div class="tooltip">Right <span class="tooltiptext toolRight">Tooltip text</span></div><br /> <div class="tooltip">Bottom <span class="tooltiptext toolBottom">Tooltip text</span></div><br /> </div>

这个问题有很多答案，但它仍然可能会帮助到一些人。它适用于所有左、右、上、下位置。
下面是css:
.m-tb-5 {
margin-top: 2px;
margin-bottom: 2px;
}
[data-tooltip] {
display: inline-block;
position: relative;
cursor: help;
padding: 3px;
}
/* Tooltip styling */
[data-tooltip]:before {
content: attr(data-tooltip);
display: none;
position: absolute;
background: #000;
color: #fff;
padding: 3px 6px;
font-size: 10px;
line-height: 1.4;
min-width: 100px;
text-align: center;
border-radius: 4px;
}
/* Dynamic horizontal centering */
[data-tooltip-position="top"]:before,
[data-tooltip-position="bottom"]:before {
left: 50%;
-ms-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-webkit-transform: translateX(-50%);
transform: translateX(-50%);
}
/* Dynamic vertical centering */
[data-tooltip-position="right"]:before,
[data-tooltip-position="left"]:before {
top: 50%;
-ms-transform: translateY(-50%);
-moz-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
transform: translateY(-50%);
}
[data-tooltip-position="top"]:before {
bottom: 100%;
margin-bottom: 6px;
}
[data-tooltip-position="right"]:before {
left: 100%;
margin-left: 6px;
}
[data-tooltip-position="bottom"]:before {
top: 100%;
margin-top: 6px;
}
[data-tooltip-position="left"]:before {
right: 100%;
margin-right: 6px;
}
/* Tooltip arrow styling/placement */
[data-tooltip]:after {
content: '';
display: none;
position: absolute;
width: 0;
height: 0;
border-color: transparent;
border-style: solid;
}
/* Dynamic horizontal centering for the tooltip */
[data-tooltip-position="top"]:after,
[data-tooltip-position="bottom"]:after {
left: 50%;
margin-left: -6px;
}
/* Dynamic vertical centering for the tooltip */
[data-tooltip-position="right"]:after,
[data-tooltip-position="left"]:after {
top: 50%;
margin-top: -6px;
}
[data-tooltip-position="top"]:after {
bottom: 100%;
border-width: 6px 6px 0;
border-top-color: #000;
}
[data-tooltip-position="right"]:after {
left: 100%;
border-width: 6px 6px 6px 0;
border-right-color: #000;
}
[data-tooltip-position="left"]:after {
right: 100%;
border-width: 6px 0 6px 6px;
border-left-color: #000;
}
/* Show the tooltip when hovering */
[data-tooltip]:hover:before,
[data-tooltip]:hover:after {
display: block;
z-index: 50;
}
HTML标签可以是这样的:
<p data-tooltip-position="right" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="left" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="top" data-tooltip="Some tooltip text here" title=" > text here </p> .
<p data-tooltip-position="bottom" data-tooltip="Some tooltip text here" title=" > text here </p> .
我的版本是
.tooltip{
display: inline;
position: relative; /** very important set to relative*/
}
.tooltip:hover:after{
background: #333;
background: rgba(0,0,0,.8);
border-radius: 5px;
bottom: 26px;
color: #fff;
content: attr(title); /**extract the content from the title */
left: 20%;
padding: 5px 15px;
position: absolute;
z-index: 98;
width: 220px;
}
.tooltip:hover:before{
border: solid;
border-color: #333 transparent;
border-width: 6px 6px 0 6px;
bottom: 20px;
content: "";
left: 50%;
position: absolute;
z-index: 99;
}
然后是HTML
<div title="This is some information for our tooltip." class="tooltip">bar </div>
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>.

好了，这是你满足的所有赏金要求:
没有jQuery 即时出现 直到老鼠离开这个区域才会消失 淡入/淡出效果纳入 最后. .简单的解决方案
下面是一个演示和我的代码链接(JSFiddle)
以下是我在这款纯JS、CSS和HTML5游戏中加入的功能:
你可以设置淡出的速度。 您可以使用一个简单的变量来设置工具提示的文本。
HTML:
<div id="wrapper">
<div id="a">Hover over this div to see a cool tool tip!</div>
</div>
CSS:
#a{
background-color:yellow;
padding:10px;
border:2px solid red;
}
.tooltip{
background:black;
color:white;
padding:5px;
box-shadow:0 0 10px 0 rgba(0, 0, 0, 1);
border-radius:10px;
opacity:0;
}
JavaScript:
var div = document.getElementById('wrapper');
var a = document.getElementById("a");
var fadeSpeed = 25; // a value between 1 and 1000 where 1000 will take 10
// seconds to fade in and out and 1 will take 0.01 sec.
var tipMessage = "The content of the tooltip...";
var showTip = function(){
var tip = document.createElement("span");
tip.className = "tooltip";
tip.id = "tip";
tip.innerHTML = tipMessage;
div.appendChild(tip);
tip.style.opacity="0"; // to start with...
var intId = setInterval(function(){
newOpacity = parseFloat(tip.style.opacity)+0.1;
tip.style.opacity = newOpacity.toString();
if(tip.style.opacity == "1"){
clearInterval(intId);
}
}, fadeSpeed);
};
var hideTip = function(){
var tip = document.getElementById("tip");
var intId = setInterval(function(){
newOpacity = parseFloat(tip.style.opacity)-0.1;
tip.style.opacity = newOpacity.toString();
if(tip.style.opacity == "0"){
clearInterval(intId);
tip.remove();
}
}, fadeSpeed);
tip.remove();
};
a.addEventListener("mouseover", showTip, false);
a.addEventListener("mouseout", hideTip, false);
这是一个漂亮的jQuery工具提示:
https://jqueryui.com/tooltip/
要实现这一点，只需遵循以下步骤:
Add this code in your <head></head> tags: <script type="text/javascript" src="http://cdn.jquerytools.org/1.2.5/full/jquery.tools.min.js"></script> <script type="text/javascript"> $("[title]").tooltip(); </script> <style type="text/css"> /* tooltip styling. by default the element to be styled is .tooltip */ .tooltip { display:none; background:transparent url(https://dl.dropboxusercontent.com/u/25819920/tooltip/black_arrow.png); font-size:12px; height:70px; width:160px; padding:25px; color:#fff; } </style> On the HTML elements that you want to have the tooltip, just add a title attribute to it. Whatever text is in the title attribute will be in the tooltip.
注意:当JavaScript被禁用时，它将回退到默认的浏览器/操作系统工具提示。
