动态调整图像映射和图像的大小

如果最终使用Javascript完成任务，则可以使用以下跨浏览器代码段来调整

MAP

window.onload = function () {    var ImageMap = function (map) { var n,     areas = map.getElementsByTagName('area'),     len = areas.length,     coords = [],     previousWidth = 1920; for (n = 0; n < len; n++) {     coords[n] = areas[n].coords.split(','); } this.resize = function () {     var n, m, clen,         x = document.body.clientWidth / previousWidth;     for (n = 0; n < len; n++) {         clen = coords[n].length;         for (m = 0; m < clen; m++) {  coords[n][m] *= x;         }         areas[n].coords = coords[n].join(',');     }     previousWidth = document.body.clientWidth;     return true; }; window.onresize = this.resize;        },        imageMap = new ImageMap(document.getElementById('map_ID'));    imageMap.resize();}

previousWidth

<div ><img id="Image-Maps_5201211070133251" src="Site.png" usemap="#Image-Maps_5201211070133251" border="0" width="100%" alt="" />
