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。

您还可以自定义工具提示样式。请参阅此连结: http://jqueryui.com/tooltip/#custom-style

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>

不使用任何API 你也可以通过使用纯CSS和Jquery演示来做这样的事情

HTML

<div class="pointer_tooltip"> 
    Click & Drag to draw the area
</div>

CSS

.pointer_tooltip{
  width : auto;
  height : auto;
  padding : 10px;
  border-radius : 5px;
  background-color : #fff;
  position: absolute;
}

Jquery

$(document).mousemove(function( event ) {
    var pageCoords = "( " + event.pageX + ", " + event.pageY + " )";   

    //set the actuall width
    $('.pointer_tooltip').width($('.pointer_tooltip').width());
    var position_top = event.pageY+18;
    var position_left = event.pageX-60;          
    var width=$('body').width()-$('.pointer_tooltip').width();

    //check if left not minus
    if(position_left<0){
      position_left=10;
    }else if(position_left > width){
     position_left=width-10;
    }       


    $('.pointer_tooltip').css('top',position_top+'px');
    $('.pointer_tooltip').css('left',position_left+'px');
});

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> .
