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

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>

其他回答

我做了一些事情，应该能够适应一个div以及。

HTML

<td>
    <%# (Eval("Name").ToString().Length > 65) ? Eval("Name").ToString().Substring(0, 60) + "..." : Eval("Name")%>
    <span class="showonhover">
        <a href="#"><%# (Eval("Name").ToString().Length > 65) ? "More" : "" %></a>
        <span class="hovertext">
            <%# Eval("Name") %>
        </span>
    </span>
</td>

CSS

.showonhover .hovertext { display: none;}
.showonhover:hover .hovertext {display: inline;}
a.viewdescription {color:#999;}
a.viewdescription:hover {background-color:#999; color: White;}
.hovertext {position:absolute;z-index:1000;border:1px solid #ffd971;background-color:#fffdce;padding:11px;width:150px;font-size: 0.75em;}

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。

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")
