悬停时地图颜色变化？

Question

我不确定哪种方法是最好的。 的一点是，创建一个交互式地图，我知道这些方式，使其工作：

<map id="mapdk" name="mapdk"> 
<area shape="poly" coords="7,230,12,230,14,232,17,233,20,230,22,231,25,234,29,235,31,231,33,228,39,228,43,228,46,232,50,232,51,225,56,223,60,222,62,223,61,227,64,229,68,228,71,225,74,221,77,217,80,215,82,215,84,217,87,218,91,219,92,222,94,225,94,227,95,230,97,230,99,232,100,234,103,234,105,234,105,237,105,239,108,239,109,240,109,243,105,245,104,244,105,247,108,246,110,246,114,246,117,247,121,247,124,247,127,247,130,246,134,244,133,241,136,240,134,238,132,236,135,233,134,230,130,230,126,230,122,229,124,226,126,226,129,225,133,224,136,224,139,224,140,225,141,227,144,228,145,224,146,221,148,217,148,212,148,208,148,202,147,195,146,188,149,184,152,182,154,179,156,176,159,173,161,174,162,176,162,179,161,184,158,183,157,183,154,185,155,187,156,189,159,188,162,186,165,187,169,182,172,182,174,182,175,184,173,186,175,189,177,191,179,187,179,183,185,177,188,171,191,164,193,156,191,151,187,147,184,143,178,144,173,145,168,146,160,145,154,143,151,140,150,138,147,143,146,148,142,151,136,154,153,133,153,129,153,125,150,119,147,112,147,106,147,101,148,94,152,87,153,81,154,76,157,69,159,64,163,62,164,55,161,45,163,40,165,35,159,29,156,22,156,17,157,12,159,8,162,5,166,2,169,0,161,1,156,5,152,8,148,12,144,15,140,17,134,19,130,18,126,19,121,22,117,30,100,59,94,64,82,71,69,72,64,71,60,72,54,76,49,77,40,77,35,78,27,87,23,93,17,102,14,111,13,117,16,117,17,121,20,126,24,129,28,135,31,139,32,140,35,138,38,135,38,134,38,131,37,130,35,128,33,127,30,126,30,121,29,116,32,113,38,109,39,111,41,112,36,114,35,116,34,121,35,123,38,128,41,129,43,128,45,127,49,126,50,123,53,118,54,115" href="#" /> 
    <area shape="poly" coords="34,213" href="#" /></map> 

也使用这样的事情：

#mapdk { 
list-style: none; 
background: url(images/mapdk.png) no-repeat 0 0; 
position: relative; 
width: 580px; 
height: 268px; 
margin: 0; 
padding: 0; 
} 

#mapdk:hover { 
background: url(images/mapdk_red.png) no-repeat 0 0; 
} 

，最后用canvas

但其其中一个是制作这样的任务的最多optimal。

Answer 1

取决于你所说的最佳内容。如果你正在创建地图，我会说map可能是最好的方法。为什么在有一个元素想用于这个目的时使用别的东西？

现在，如果您有一些使用map无法完成的特殊功能（例如动画或图形），则应考虑使用canvas。

为了达到:hover的目的，它们都是相同的。我不会使用悬停的东西不是button，虽然（我会使用JS），但由于您使用的是html5它应该不是一个真正的问题（你不支持旧浏览器）。
