html - 悬停时 map 颜色变化？

Question

我不确定哪种方法最好。关键是，创建一个交互式 map 我知道这些方法可以让它发挥作用:

<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>

也使用这样的东西:

#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;
}

最后使用canvas

但是哪一个是最最优来完成这样的任务。

Answer 1

取决于您所说的最优是什么意思。如果您要创建 map ，我认为 map 可能是最好的方法。既然有一个元素被认为是为此目的，为什么还要使用其他东西？

现在，如果您有一些无法使用 map 完成的特殊功能(例如动画或图形)，您应该考虑使用 canvas。

对于 :hover 而言，它们是相同的。不过，我不会将悬停用于不是 button 的东西(我会使用 JS)，但由于您使用的是 html5，所以这应该不是问题(无论如何你都不支持旧的浏览器)。
