Question

我正在实施网络应用程序。现在我有一个州的MAP image，我通过计算该区的坐标来划分每个区。

以下是我正在使用的MAP图片：

enter image description here 以下是协调点：

<area id="puneArea" shape="poly" coords="154,250,157,250,158,251,160,251,162,253,165,253,167,254,170,254,173,254,174,255,175,257,175,258,177,260,178,262,179,263,182,264,184,264,187,266,190,267,192,267,196,267,198,267,199,268,199,270,198,271,198,274,195,275,192,276,191,278,190,279,190,283,190,284,191,287,192,288,195,291,196,293,198,296,201,297,203,301,204,302,207,302,208,302,209,306,211,310,213,312,213,312,215,314,216,314,217,316,219,318,219,321,220,322,221,325,221,326,222,329,224,330,224,331,225,334,226,337,226,338,228,339,229,339,229,339,232,338,232,337,232,335,234,335,237,335,237,335,238,338,238,339,238,340,238,342,241,343,242,344,243,346,245,347,245,348,246,350,246,354,246,358,247,359,249,359,250,358,251,358,254,358,255,358,257,358,258,356,259,358,262,359,263,359,266,361,266,364,268,364,270,364,271,367,272,368,274,369,275,371,275,372,276,373,274,375,271,376,267,379,266,381,266,384,266,384,266,385,268,385,270,385,271,388,270,389,268,390,262,390,260,390,258,389,255,389,253,388,250,386,249,384,242,382,238,381,233,380,228,377,224,377,221,377,216,377,213,376,211,376,208,375,205,375,204,375,203,373,200,373,194,373,191,373,190,373,187,372,184,371,182,369,179,369,175,368,173,367,169,365,166,365,162,365,163,367,163,371,162,372,161,373,158,375,158,376,154,377,153,377,146,377,144,377,141,377,137,377,136,375,136,373,136,371,137,368,140,367,139,364,133,364,131,361,129,361,129,359,129,356,131,355,127,354,125,354,123,352,120,348,120,347,118,342,116,337,116,337,116,334,115,331,114,329,112,326,112,323,112,321,112,320,112,318,112,316,114,313,114,310,115,309,115,308,116,304,116,304,116,301,119,299,120,296,121,295,123,292,125,289,128,288,131,285,131,284,131,283,131,281,131,278,131,275,131,275,131,270,132,270,133,270,136,268,137,267,137,267,140,267,141,266,142,264,144,260,144,259,144,258,144,258,144,258

当我点击Pune district区域时，我可以显示新页面。但是现在我想要的是，当在Pune区域的mouserOver时，Pune区域会显示出看起来像＆＃34;这是pune area＆＃34;。

那么如何在javascript或jquery中执行此操作。

任何帮助都将不胜感激。谢谢

Answer 1

在您的情况下，您应该将地图视为矢量或SVG，然后您可以填充区域，或者高亮显示它，添加描边等等，这可以使用jvectormaps

来完成

有很好的supposrt并且易于使用，你可以从这里开始：

P.S：您可以添加自己的自定义地图。

Answer 2

如果您想要突出显示区域 onMouseOver 事件

，请检查这些链接

Using jQuery to highlight a div, whilst greying out others

如果您的意思是缩放，增长或缩小，您可以使用 jquery 动画

http://docs.jquery.com/Effects/animate

另请查看以下链接，

Is there a way to grow/shrink an image on hover using Jquery?

Answer 3

您可以为每个区域标记创建一个onmouseover事件，并将该区域的名称作为javascript函数的参数传递，如下所示。

<area shape="rect" coords="0,0,82,126" alt="Sun" href="pune.html" onmouseover="PopName('Pune')">

您可以根据需要显示region参数。我刚刚弹出一个警告框供您参考。

<script>
function PopName(x) {
   alert("This is" + x);
}
</script>

要突出显示Pune区域，您可以添加动态css。

以下是示例代码。您可以根据网络需要即兴创作。

<body>
<p id="p1" onmouseover="change()"></p>
<img src="http://i.stack.imgur.com/u5F7E.png" usemap="#newname">
<map name="newname">
<area shape="rect" coords="0,0,82,126" alt="Sun" href="index.html" onmouseover="PopName('Mumbai')">
</map>
<div id="pop"></div>
</body>
<script>
function PopName(x) {
   document.getElementById("pop").innerHTML = '<img src="http://www.world-guides.com/images/mumbai/mumbai_city_map.jpg">';
   document.getElementById("p1").innerHTML = "This is " + x;
}
</script>

在onmouseover上创建部分图像
