前段時間利用閑暇之于自己做了個網絡象棋對戰平臺，它是基于B/S結構的網絡應用。
主要利用了javascript, DWR(AJAX框架)技術。我將會陸續用幾個貼來介紹這個對戰平臺是如何實現的。
首先來介紹我是如何構建棋盤的。
棋盤一共分這三層，第一層是棋盤，第二層為網格，第三層為棋子。用DIV標簽來表明他們的層次關系。
HTML代碼如下：
<div id="chessboard">
<div id="grid_0_0"><div id="zhu_0_0"></div></div>
<div id="grid_0_1"><div id="ma_0_0"></div></div>
<div id="grid_0_2"><div id="xiang_0_0"></div></div>
<div id="grid_0_3"><div id="shi_0_0"></div></div>
<div id="grid_0_4"><div id="shuai_0_0"></div></div>
<div id="grid_0_5"><div id="shi_0_1"></div></div>

加入這些網頁元素后，我們再來給他們添加效果，也就是那些象棋的圖案。這些代碼都是在網頁載入時加載的。
代碼如下：

//調整網格的位置
//如果構建表格直接用CSS效果會更好些,但用js控制更省力。
function createGridStyle(){
var divObj = null;
var top = null;
var left = null;
for(row = 0; row < 10; row++){
for(col = 0; col < 9; col++){
divObj = document.getElementById("grid_"+row+"_"+col);
top = row * 55;
left = col * 55;
divObj.style.position="absolute";
divObj.style.top=top;
divObj.style.left=left;
divObj.style.width=55;
divObj.style.height=55;
divObj.style.zIndex=2;
}
}
}
在頁面的未尾調用此javascript函數。
<script type="text/javascript">
createGridStyle();
</script>
這樣整個棋盤就做好了。加載頁面后整個棋盤就會展現在你的眼前。
