HTML-工具提示相对于鼠标指针的位置

小开

最佳答案

对于默认的工具提示行为，只需添加 title属性。

<div title="regular tooltip">Hover me</div>

在您澄清这个问题之前，我用纯 JavaScript 完成了这项工作，希望您会发现它很有用。图像将弹出并跟随鼠标。

JsFiddle

JavaScript

var tooltipSpan = document.getElementById('tooltip-span');


window.onmousemove = function (e) {
var x = e.clientX,
y = e.clientY;
tooltipSpan.style.top = (y + 20) + 'px';
tooltipSpan.style.left = (x + 20) + 'px';
};

CSS

.tooltip span {
display:none;
}
.tooltip:hover span {
display:block;
position:fixed;
overflow:hidden;
}

扩展多个元素

对于多个元素的一个解决方案是更新所有工具提示 span，并在鼠标移动时将它们设置在光标下。

JsFiddle

var tooltips = document.querySelectorAll('.tooltip span');


window.onmousemove = function (e) {
var x = (e.clientX + 20) + 'px',
y = (e.clientY + 20) + 'px';
for (var i = 0; i < tooltips.length; i++) {
tooltips[i].style.top = y;
tooltips[i].style.left = x;
}
};

我们可以在 Angularjs 使用“指令”来达到同样的目的。

            //Bind mousemove event to the element which will show tooltip
$("#tooltip").mousemove(function(e) {
//find X & Y coodrinates
x = e.clientX,
y = e.clientY;


//Set tooltip position according to mouse position
tooltipSpan.style.top = (y + 20) + 'px';
tooltipSpan.style.left = (x + 20) + 'px';
});

您可以使用 jQueryUI 插件，以下是引用 URL

对于工具提示相对于鼠标指针的位置，将跟踪设置为 TRUE 例如。

$('.tooltip').tooltip({ track: true });

我更喜欢这种方法:

function showTooltip(e) {
var tooltip = e.target.classList.contains("tooltip")
? e.target
: e.target.querySelector(":scope .tooltip");
tooltip.style.left =
(e.pageX + tooltip.clientWidth + 10 < document.body.clientWidth)
? (e.pageX + 10 + "px")
: (document.body.clientWidth + 5 - tooltip.clientWidth + "px");
tooltip.style.top =
(e.pageY + tooltip.clientHeight + 10 < document.body.clientHeight)
? (e.pageY + 10 + "px")
: (document.body.clientHeight + 5 - tooltip.clientHeight + "px");
}


var tooltips = document.querySelectorAll('.couponcode');
for(var i = 0; i < tooltips.length; i++) {
tooltips[i].addEventListener('mousemove', showTooltip);
}

.couponcode {
color: red;
cursor: pointer;
}


.couponcode:hover .tooltip {
display: block;
}


.tooltip {
position: absolute;
white-space: nowrap;
display: none;
background: #ffffcc;
border: 1px solid black;
padding: 5px;
z-index: 1000;
color: black;
}

在没有 JS 的情况下实现这一点的一种方法是使用 hover 操作来显示一个隐藏的 HTML 元素，参见下面的 codepen:

Http://codepen.io/c0un7z3r0/pen/lzwxew

注意，包含工具提示内容的 span 是相对于父 li 的:

ul#list_of_thrones li > span{
display:none;
}
ul#list_of_thrones li:hover > span{
position: absolute;
display:block;
...
}

正如您所看到的，span 是隐藏的，除非列表项悬停在上面，这样就显示了 span 元素，span 可以包含您需要的任何 html。在所附的 codepen 中，我还为箭头使用了一个: after 元素，但是这个元素当然是完全可选的，并且只是出于美观的目的才包含在这个示例中。

我希望这有所帮助，因为所有其他的答案都包括了 JS 解决方案，但 OP 只要求 HTML/CSS 解决方案，所以我不得不发布。

这可以用纯 HTML 和 css 来完成。这可能不是最好的方法，但我们都有不同的局限性。根据你的具体情况，有3种方法可能是有用的。

第一种方法包括在链接顶部覆盖一个不可见的表，并在每个显示图像的单元格上进行悬停操作。

#imagehover td:hover::after{
content: "             ";
white-space: pre;
background-image: url("http://www.google.com/images/srpr/logo4w.png");
position: relative;
left: 5px;
top: 5px;
font-size: 20px;
background-color: transparent;
background-position: 0px 0px;
background-size: 60px 20px;
background-repeat: no-repeat;
  

}




#imagehover table, #imagehover th, #imagehover td {
border: 0px;
border-spacing: 0px;
}

<a href="https://www.google.com">
<table id="imagehover" style="width:50px;height:10px;z-index:9999;position:absolute" cellspacing="0">
<tr><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr>

第二种方法依赖于能够提供您自己的光标图像

While the normal title tooltip doesn't technically allow images it does allow any unicode characters including block letters and emojis which may suit your needs.
