很久以前学google map写的 
<DIV >看到人家托动时显示的不是背景色而是地图，就学的写了这个。arcims9.2已经可以实现这个功能了。这个是9。0时代net_link的产物。 注意：附录中的cs代码已经修改成9.2adf的连接器了。 注意：不能应用于动态加载的图层。 一、概述 思路：使用table分为9个块，中间的块为主显示框，周边为点缀的块。 以下“0”表示原点位置，其它为分块的编号. .-----.------.------ | 1 | 2 | 3 | .-----0------.------ | 8 | - | 4 | .-----.------.------ | 7 | 6 | 5 | -------------------- 二、修改 1.修改MapFrame.htm主文件 屏蔽标注//map image后面两行 //var content = '<img name="theImage" src="images/map.gif" hspace=0 vspace=0 border=0 width=' + mWidth + ' height=' + mHeight + '> '; //createLayer("theMap",0,0,sWidth,sHeight,true,content); 2.添加新的参数,这里构建了一个3*3的表格,在表格中插入img标签 var iMapLeft = -iWidth; var iMapTop = -iHeight; var sMapthe = '<div id="theMapTable" style="position: absolute;z-index: 1; left:0px;top:0px;border: 3px double #00FFFF">'; sMapthe += '<table border="0" id="table1" cellspacing="0" cellpadding="0">'; sMapthe += '<tr>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer1">'; sMapthe += '<img src ="" name="theImage1" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer2">'; sMapthe += '<img src ="" name="theImage2" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer3">'; sMapthe += '<img src ="" name="theImage3" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '</tr>'; sMapthe += '<tr><td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer8">'; sMapthe += '<img src ="" name="theImage8" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div>'; sMapthe += '</td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer">'; sMapthe += '<img src ="" name="theImage" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div>'; sMapthe += '</td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer4">'; sMapthe += '<img src ="" name="theImage4" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div>'; sMapthe += '</td>'; sMapthe += '</tr>'; sMapthe += '<tr>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer7">'; sMapthe += '<img src ="" name="theImage7" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer6">'; sMapthe += '<img src ="" name="theImage6" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '<td><div style="OVERFLOW: auto; width: 100%; height: 100%; z-index: 1" id="maplayer6">'; sMapthe += '<img src ="" name="theImage5" hspace=0 vspace=0 border=0 height="'+iHeight+'" width="'+iWidth+'"></div></td>'; sMapthe += '</tr>'; sMapthe += '</table></div>'; document.writeln('<div id="theMap" style="OVERFLOW: hidden; Top:0px;left:0px;WIDTH: '+(sWidth*3)+'px;HEIGHT: '+(sHeight*3)+'px; POSITION: relative; BACKGROUND-COLOR: #3399ff">'+sMapthe+'</div>'); 3.在aimsXML.js中添加新的函数getExp(),用于计算和显示地图 这个文件之间连接了一个aspx页面,这个页面主要就是返回相应大小的地图. function getExp(){ moveLayer("theMap",iMapLeft,iMapTop); for (var i=1;i<9;i++){ var name = "theImage"+i; theObj = document.getElementById(name); if (theObj!=null){ switch(i){ case 1: getMapXY(-iWidth,-iHeight); efTop = mapY; efRight = eLeft; efLeft = mapX; efBottom = eTop; break; case 2: getMapXY(0,-iHeight); efTop = mapY; efLeft = mapX; getMapXY(iWidth,0); efRight = mapX; efBottom = mapY; break; case 3: getMapXY(iWidth,-iHeight); efTop = mapY; efLeft = mapX; getMapXY(iWidth+iWidth,0); efRight = mapX; efBottom = mapY; break; case 4: getMapXY(iWidth,0); efTop = mapY; efLeft = mapX; getMapXY(iWidth+iWidth,iHeight); efRight = mapX; efBottom = mapY; break; case 5: efTop = eBottom; efLeft = eRight; getMapXY(iWidth+iWidth,iHeight+iHeight); efRight = mapX; efBottom = mapY; break; case 6: getMapXY(0,iHeight); efTop = mapY; efLeft = mapX; getMapXY(iWidth,iHeight+iHeight); efRight = mapX; efBottom = mapY; break; case 7: getMapXY(-iWidth,iHeight); efTop = mapY; efLeft = mapX; getMapXY(0,iHeight+iHeight); efRight = mapX; efBottom = mapY; break; case 8: getMapXY(-iWidth,0); efTop = mapY; efLeft = mapX; getMapXY(0,iHeight); efRight = mapX; efBottom = mapY; break; } theObj.src = 'http://localhost/map.aspx?XMin='+efLeft+';YMin='+efBottom+';XMax='+efRight+';YMax='+efTop+';H='+iHeight+';W='+iWidth+';li=0;other='; } } } 4.在aimsXML.js文件的processXML()函数中添加上述函数. 添加位置在case 1:中,主要是显示地图. case 1: ....... getExp();//每次刷新地图后运行 break; case 2: ...... 5.在aimsXML.js文件中查找resetPanImage()函数 屏蔽以下语句 //clipLayer2("theMap",0,0,iWidth,iHeight); 6.在aimsNavigation.js文件中查找panMouse()函数 屏蔽以下语句 //clipLayer2("theMap",cLeft,cTop,cRight,cBottom); 修改moveLayer("theMap",xMove+hspc,yMove+vspc);为 moveLayer("theMap",xMove+hspc+iMapLeft,yMove+vspc+iMapTop); 7.用"moveLayer("theMap""查询全部文件夹,打来文件依次修改全部moveLayer("theMap",hspc,vspc);函数为 moveLayer("theMap",iMapLeft,iMapTop);</DIV>
