向div添加工具提示

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。

当前回答

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:

我为它创造了一个公式。首先是html

<div class="tooltip-container">
  <button class="tooltip-tarjet">
    My Button
  </button>
  <div class="tooltip-element"> 
    This is my tooltip content right here...
  </div>
</div>

现在是它的css

.tooltip-container { 
  /* it contains the tooltip message and the one firing the tooltip
   * it has position relative since it allows for a better responsive positioning
   * of the tooltip-element */
  display: inline-block;
  position: relative;
  flex-direction: row;
}
.tooltip-tarjet:hover + .tooltip-element {
  /* this selector rule matches the tooltip-element right after
   * tooltip-tarjet at a hover action
   *  */
  display: inline-block;
  position: absolute;
  background-color: #869096;
  color: white;
  opacity: 1;
  transition: all 1s;
}
.tooltip-element { 
  /* here goes the tooltip-element styles and positioning, now your
   * tooltip element will always remain to your desired positionno matter
   * the screen size at hand 
   *  */ 
  display: none; 
  opacity: 0;
  text-align: center;
  padding: 7px;
  z-index: 10;
  width: 200px;
  left: -60px;
  bottom: 48px;
  border-radius: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  font-size: 12px;
  line-height: 1.5;
}

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。

你可以像这样在onmouseover和onmouseout期间切换子div:

function Tooltip(el, text) {
  el.onmouseover = function() {
    el.innerHTML += '<div class="tooltip">' + text + '</div>' 
    }
  el.onmouseout = function() {
    el.removeChild(el.querySelector(".tooltip"))
  }
}

//Sample Usage
Tooltip(document.getElementById("mydiv"),"hello im a tip div")

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>

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);
