html图片热点切换图片

Question

我在地图上有一个图像热点，它会在悬停时将图像移出，但是我希望图像保持打开更长时间，并且只有在用户将光标移到新的交换图像轮廓而不是原来的热点，这样的可能吗？

到目前为止我的代码

<div class="mapwrap" style="text-align:center;"><img src="/dev/test/templates/jwd25template/images/map-blank.png" alt="wc" name="map" width="700" height="400" usemap="#mapMap" id="map" border="0" ></div>
<map name="mapMap">
<area shape="poly" coords="231,299,236,309,239,314,242,324,242,333,241,340,237,342,232,342,232,346,236,348,239,352,242,359,244,360,246,363,249,371,245,374,243,378,244,379,252,373,253,375,255,378,255,380,260,382,260,381,266,384,269,387,272,389,275,390,276,390,279,390,287,386,288,383,293,381,298,380,303,379,306,379,307,380,310,380,314,378,317,378,320,378,322,376,325,374,330,372,337,370,342,370,347,372,349,372,355,372,358,370,359,369,355,366,352,363,354,358,356,358,354,355,349,354,348,354,342,355,339,352,339,348,341,344,344,339,349,337,352,332,352,327,357,325,362,324,370,323,373,316,372,312,367,309,366,310,360,308,355,311,350,315,346,317,342,315,337,313,331,310,327,307,326,314,325,318,323,322,321,324,314,324,309,327,306,330,304,334,303,335,300,337,297,339,294,341,291,341,288,341,283,339,280,334,280,329,283,325,283,324,277,328,271,331,269,334,269,335,266,327,269,321,266,319,264,317,257,315,257,310,256,302,255,296,255,292,254,286,246,281,239,280,240,285,233,287,231,293,229,296,229,296" href="takke/western-cape" target="_parent" alt="WC" onMouseOver="MM_swapImage('map','','/dev/test/templates/jwd25template/images/map-WC-2.png',1)"  onMouseOut="MM_swapImgRestore('map','','/dev/test/templates/jwd25template/images/map-blank.png',1)"></map>

我尝试添加一个 onMouseOut 网址，但我意识到这行不通。

试着把我的头绕过去，任何想法都将不胜感激:)

Answer 1

你可以用 CSS 做到这一点

HTML 代码：

<map id="big_map_area">
  <area shape="poly" id="map_hover" coords="231,299,2..." href="takke/western-cape" target="_parent" alt="WC">
</map>

CSS 代码：

#map_hover {
opacity:0.0;
}

查询代码：

 $("#map_hover").mouseover(function () {
     this.css('opacity', '1.0');
 });
 $("#big_map_area").mouseout(function () {
     $("#map_hover").css('opacity', '0.0');
 });

因此，当鼠标进入地图内的小 poligon 时，您会显示您的图像，并在您离开大地图容器时交换图像。

现在应该可以了。
