Question

此页面上的地图http://www.marktoe.co.za/dev/agrimark/takke正在使用热点，不过我想知道当你将鼠标悬停在某个省份并且放大的图像出现时，只有当鼠标离开放大的图像边框时它才会消失。目前，当移出放大图像下方的热点时它会关闭，如果在大图像周围徘徊导致混淆，则在后台找到其他热点。我一直在尝试的代码

<script type="text/javascript">

}
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}

function MM_findObj(n, d) { //v4.01

Answer 1

我建议将函数设置为容器div的onmouseout事件。

<div id='enlargedView' onmouseout='enlargedView_MouseOut(this)'>

或者你可以在javascript中动态添加它。

enlargedView.addEventListener("MouseOut", enlargeView_MouseOut);//2cnd argument is a function

如果需要，可以删除下方地图的事件监听器

var fullMap = document.getElementById("FullMap");
fullMap.removeEventListener("MouseOver" , FullMap_MouseOver);

注意：我使用自己的变量和元素名称。

并创建一个javascript函数来处理它。当鼠标离开元素时会发生onmouseout事件。

提示：onmouseleave事件类似于onmouseout事件。该唯一的区别是onmouseleave事件不会冒泡（不会向上传播文档层次结构）。请参阅＆＃34;更多示例＆＃34;在这个页面的底部是为了更好地理解差异。

您可以使用该事件将变量设置为false，并将showEnlargedImage基于该变量

var onMap = null;
function MapContainer_MouseOut()
{
    onMap = false;
}

function MapContainer_MouseEnter()
{
    onMap = true;
}

function showEnlargeImage()
{
    if(onMap === true)
    {
     //show image enlarged code
    }
}

使用JS保持翻转图像打开，直到鼠标离开地图外部容器
