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。

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")

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>

你可以使用纯CSS制作工具提示。试试这个。希望能帮助你解决你的问题。

HTML

<div class="tooltip"> Name
    <span class="tooltiptext">Add your tooltip text here.</span>
</div>

CSS

.tooltip {
        position: relative;
        display: inline-block;
        cursor: pointer;
    }

    .tooltip .tooltiptext {
        visibility: hidden;
        width: 270px;
        background-color: #555;
        color: #fff;
        text-align: center;
        border-radius: 6px;
        padding: 5px 0;
        position: absolute;
        z-index: 1;
        bottom: 125%;
        left: 50%;
        margin-left: -60px;
        opacity: 0;
        transition: opacity 1s;
    }

    .tooltip .tooltiptext::after {
        content: "";
        position: absolute;
        top: 100%;
        left: 50%;
        margin-left: -5px;
        border-width: 5px;
        border-style: solid;
        border-color: #555 transparent transparent transparent;
    }

    .tooltip:hover .tooltiptext {
        visibility: visible;
        opacity: 1;
    }

仅css3的解决方案可以是:

CSS3:

div[id^="tooltip"]:after {content: attr(data-title); background: #e5e5e5; position: absolute; top: -10px; left:  0; right: 0; z-index: 1000;}

HTML5:

<div style="background: yellow;">
    <div id="tooltip-1" data-title="Tooltip Text" style="display: inline-block; position: relative; background: pink;">
        <label>Name</label>
        <input type="text" />
    </div>
</div>

然后你可以用同样的方法创建一个tooltip-2 div…当然，您也可以使用title属性而不是data属性。

您可以尝试引导工具提示。

$(function () {
  $('[data-toggle="tooltip"]').tooltip()
})

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;
}
