Question

我正在整理一张悬浮状态的美国地图，我需要以某种方式触发。我构建它的方式（以前在较小的规模上完成此操作没有问题）是对美国的主图像进行图像映射，给每个区域一个id，然后使用jQuery显示/隐藏绝对定位的div upop地图。每个div都包含一个带有自己的map的图像，当moused只是发送一个show（）命令以便它保持放置。

我也有一些jquery隐藏了mouseleave上的所有div。问题是，悬停效果在这种疯狂的口吃效果中不断开启和关闭。我究竟做错了什么？正如您所看到的，我已经尝试了各种功能，包括鼠标悬停，鼠标中心和悬停。

我的jQuery：

$(function() { // Equivalent to $(document).ready(function() 
  if (!$.browser.msie && !$.browser.version.substr(0,1)<7) {
   $("area").mouseleave(function(){
    $("#mapContainer div").animate({opacity: 1.0}, 100).fadeOut();
   });
  }

  $("#californiaHotspot, #californiaActiveArea").mouseover(function(){
   $("#california").show();
  });

  $("#idahoHotspot, #idahoActiveArea").mouseenter(function(){
   $("#idaho").fadeIn();
  });

  $("#nevadaHotspot, #nevadaActiveArea").mouseenter(function(){
   $("#nevada").fadeIn();
  });
  $("#nevadaActiveArea").mouseleave(function(){
   $("#nevada").hide();
  });

  $("#oregonHotspot, #oregonActiveArea").mouseover(function(){
   $("#oregon").fadeIn();
  });

  $("#washingtonHotspot, #washingtonActiveArea").mouseover(function(){
   $("#washington").fadeIn();
  });
});

Answer 1

我建议使用jquery .hover()方法而不是.mouseover()，.mouseenter()，.mouseleave()方法来控制图像的显示/隐藏。您可以更可靠地控制fadein（）和fadeout（）方法。

Answer 2

同意jQuery悬停是一个好主意。

另外我会考虑以下内容：

使基本地图（CAS_hotspot_exporter_v2.jpg）成为div＃mapContainer的背景图片。
使用透明的1px图像作为图像映射。
将宽度和高度设置为与基本地图图像相同。
给淡入淡出的div（例如#california）一个z-index为-1。

所有这一切意味着总是在顶部有一个透明的表面，鼠标“悬停”过来，其他的div被带到“表面下方”。这样，当新的div淡入时，浏览器不应该触发mouseleave事件。

Answer 3

在顶部有透明层的好主意。

使状态图像与国家图像大小相同，状态图像是否透明除了状态本身之外，这不是最简单的方法吗？

只是为了重复使用和弦，当然还取决于项目的性质 - 图像有多重。
