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

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> .

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。

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")

Stack Snippets & jsFiddle中的例子

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"), "I'm a tooltip") #mydiv { position: relative; display: flex; align-items: center; justify-content: center; width: 120px; height: 50px; padding: 5px 10px; background-color: #e2f7ff; box-shadow: 1px 1px 1px 0px #cecece; } .tooltip { position: absolute; display: inline-block; white-space: nowrap; width: auto; height: auto; background-color: #11121b; color: white; padding: 4px 6px; border-radius: 3px; z-index: 99; left: 100%; top: 0; } <div id="mydiv"> This is just a div </div>
