你可以用简单的css…Jsfiddle这里你可以看到这个例子

下面是工具提示的CSS代码

[data-tooltip] {
  position: relative;
  z-index: 2;
  cursor: pointer;
}

/* Hide the tooltip content by default */
[data-tooltip]:before,
[data-tooltip]:after {
  visibility: hidden;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=0);
  opacity: 0;
  pointer-events: none;
}

/* Position tooltip above the element */
[data-tooltip]:before {
  position: absolute;
  bottom: 150%;
  left: 50%;
  margin-bottom: 5px;
  margin-left: -80px;
  padding: 7px;
  width: 160px;
  -webkit-border-radius: 3px;
  -moz-border-radius: 3px;
  border-radius: 3px;
  background-color: #000;
  background-color: hsla(0, 0%, 20%, 0.9);
  color: #fff;
  content: attr(data-tooltip);
  text-align: center;
  font-size: 14px;
  line-height: 1.2;
}

/* Triangle hack to make tooltip look like a speech bubble */
[data-tooltip]:after {
  position: absolute;
  bottom: 150%;
  left: 50%;
  margin-left: -5px;
  width: 0;
  border-top: 5px solid #000;
  border-top: 5px solid hsla(0, 0%, 20%, 0.9);
  border-right: 5px solid transparent;
  border-left: 5px solid transparent;
  content: " ";
  font-size: 0;
  line-height: 0;
}

/* Show tooltip content on hover */
[data-tooltip]:hover:before,
[data-tooltip]:hover:after {
  visibility: visible;
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
  filter: progid: DXImageTransform.Microsoft.Alpha(Opacity=100);
  opacity: 1;
}

这是一个纯css3实现(可选JS)

你要做的唯一一件事就是在任何div上设置一个名为“data-tooltip”的属性，当你将鼠标悬停在它上面时，该文本将显示在它旁边。

我已经包含了一些可选的JavaScript，可以使工具提示显示在光标附近。如果您不需要这个特性，您可以放心地忽略这个小提琴的JavaScript部分。

如果您不希望在悬停状态上淡入，只需删除过渡属性。

它的样式类似于title属性工具提示。这是JSFiddle: http://jsfiddle.net/toe0hcyn/1/

HTML的例子:

<div data-tooltip="your tooltip message"></div>

CSS:

*[data-tooltip] {
    position: relative;
}

*[data-tooltip]::after {
    content: attr(data-tooltip);

    position: absolute;
    top: -20px;
    right: -20px;
    width: 150px;

    pointer-events: none;
    opacity: 0;
    -webkit-transition: opacity .15s ease-in-out;
    -moz-transition: opacity .15s ease-in-out;
    -ms-transition: opacity .15s ease-in-out;
    -o-transition: opacity .15s ease-in-out;
    transition: opacity .15s ease-in-out;

    display: block;
    font-size: 12px;
    line-height: 16px;
    background: #fefdcd;
    padding: 2px 2px;
    border: 1px solid #c0c0c0;
    box-shadow: 2px 4px 5px rgba(0, 0, 0, 0.4);
}

*[data-tooltip]:hover::after {
    opacity: 1;
}

基于鼠标位置的工具提示位置更改的可选JavaScript:

var style = document.createElement('style');
document.head.appendChild(style);

var matchingElements = [];
var allElements = document.getElementsByTagName('*');
for (var i = 0, n = allElements.length; i < n; i++) {
    var attr = allElements[i].getAttribute('data-tooltip');
    if (attr) {
        allElements[i].addEventListener('mouseover', hoverEvent);
    }
}

function hoverEvent(event) {
    event.preventDefault();
    x = event.x - this.offsetLeft;
    y = event.y - this.offsetTop;

    // Make it hang below the cursor a bit.
    y += 10;

    style.innerHTML = '*[data-tooltip]::after { left: ' + x + 'px; top: ' + y + 'px  }'

}

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>

最简单的方法是在包含元素上设置position: relative，在容器内的工具提示元素上设置position: absolute，使其相对于父元素(包含元素)浮动。例如:

<div style="background: yellow;">
    <div style="display: inline-block; position: relative; background: pink;">
        <label>Name</label>
        <input type="text" />

        <div style="background: #e5e5e5; position: absolute; top: -10px; left: 0; right: 0;">
            Tooltip text
        </div>
    </div>
</div>

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);

它可以只用CSS，不需要javascript

运行演示

[data-tooltip]:before { /* needed - do not touch */ content: attr(data-tooltip); position: absolute; opacity: 0; /* customizable */ transition: all 0.15s ease; padding: 10px; color: #333; border-radius: 10px; box-shadow: 2px 2px 1px silver; } [data-tooltip]:hover:before { /* needed - do not touch */ opacity: 1; /* customizable */ background: yellow; margin-top: -50px; margin-left: 20px; } [data-tooltip]:not([data-tooltip-persistent]):before { pointer-events: none; } /* FOR TEST PURPOSES ONLY */ div { border: 1px solid silver; background: #ddd; margin: 20px; padding: 10px; } <div>Standard div, no tooltip here</div> <div data-tooltip="Hi, I'm a tooltip. Pretty easy uh ? ;)">Div with standard tooltip. Hover me to see the tooltip. <br/>Hovering the tooltip doesn't matter: <br/>if you hover out of my boundaries, the tooltip will disappear.</div> <div data-tooltip="Hi, I'm a persistent tooltip. I won't disappear when hovering me even if out of my parent boundaries. I'll also prevent other tooltips to fire :)" data-tooltip-persistent="foo">Div with persistent tooltip. Hover me to see the tooltip. <br/>The tooltip won't expire until you hover on me OR it.</div>

Apply a custom HTML attribute, eg. data-tooltip="bla bla" to your object (div or whatever): <div data-tooltip="bla bla"> something here </div> Define the :before pseudoelement of each [data-tooltip] object to be transparent, absolutely positioned and with data-tooltip="" value as content: [data-tooltip]:before { position : absolute; content : attr(data-tooltip); opacity : 0; } Define :hover:before hovering state of each [data-tooltip] to make it visible: [data-tooltip]:hover:before { opacity : 1; } Apply your styles (color, size, position etc) to the tooltip object; end of the story.

在演示中，我定义了另一个规则来指定当鼠标悬停在工具提示上但不在父工具提示上时，工具提示是否必须消失，使用另一个自定义属性data-tooltip-persistent和一个简单的规则:

[data-tooltip]:not([data-tooltip-persistent]):before {
    pointer-events: none;
}

注1:浏览器的覆盖范围很广，但可以考虑为旧的IE使用javascript回退(如果需要的话)。

注2:一种增强可能是添加一些javascript来计算鼠标位置，并通过改变应用于它的类将其添加到伪元素中。
