Question

我有一个图像，我放了一些坐标并显示这样的工具提示：

var areas = document.getElementsByTagName('area');
var tooltip = document.getElementById('tooltip');
for (var i = 0; i < areas.length; i++) {
  areas[i].addEventListener("mouseover", updateTooltip)
}

function updateTooltip() {
  tooltip.innerHTML = this.getAttribute('data-text');
  var coordinates = this.getAttribute('coords').split(',')
  tooltip.style.left = coordinates[0] + 'px';
  tooltip.style.top = coordinates[coordinates.length - 1] + 'px';
}

.tooltip {
  position: absolute;
  z-index: 9999;
  border: 1px solid black;
  min-width: 100px;
  max-width: 150px;
  background: white;
}

area {
  position: relative;
}

.parent{
position:relative;
}

<div class="parent">
<img id="mapImage" src="https://i.imgur.com/Y7HuHDQ.png" usemap="#image-map">

<map name="image-map">

        <area target="" data-text="USA Shops: Manchester,TN - Num: 6621418372 WIXOM ,MI - Num:662728173" alt="USA" title="USA" href="" coords="110,140,182,141,186,148,198,146,198,140,214,139,224,134,234,143,221,150,213,154,205,156,205,170,199,174,194,181,193,188,162,182,158,171,149,173,145,179,141,170,124,168,121,173,112,168,105,158" shape="poly">

问题是我想在鼠标翻过工具提示或坐标时删除工具提示。因为如果我们在美国上空盘旋，我们就不能在México上盘旋，因为工具提示不允许它。

我怎样才能实现它？此致

Answer 1

使用mouseeneter＆amp; mouseleave事件并创建另一个将在mouseleave上触发的函数。在此函数中将display:none设置为工具提示并在鼠标输入中将其设置为display:block

＆＃13;

var areas = document.getElementsByTagName('area');
var tooltip = document.getElementById('tooltip');
for (var i = 0; i < areas.length; i++) {
  areas[i].addEventListener("mouseenter", updateTooltip);
  areas[i].addEventListener("mouseleave", removeTooltip)
}

function updateTooltip() {
  tooltip.style.display = "block"
  tooltip.innerHTML = this.getAttribute('data-text');
  var coordinates = this.getAttribute('coords').split(',')
  tooltip.style.left = coordinates[0] + 'px';
  tooltip.style.top = coordinates[coordinates.length - 1] + 'px';
}

function removeTooltip() {
  tooltip.style.display = "none"
}

＆＃13;

.tooltip {
  position: absolute;
  z-index: 9999;
  border: 1px solid black;
  min-width: 100px;
  max-width: 150px;
  background: white;
}

area {
  position: relative;
}

.parent {
  position: relative;
}
