6*6的格子，按下后分辨点的是哪一个，小弟我搞了两段代码还是不行 _JavaScript

6*6的格子，按下后分辨点的是哪一个，我搞了两段代码还是不行。
我就不适合编程。。。。。

JScript code


document.onmousedown=function(){
    var x=event.clientX;
    var y=event.clientY;
    for(var k=0;k<6;k++){
        for(var j=0;j<6;j++){
            if(((x>100*j+14)&&(x<100*j+86))&&((y>100*k+14)&&(x<100*k+86))){
                alert("范围内x:"+j+"\n"+"范围内y:"+k);break;
            }
        }
    }
}

JScript code



document.onmousedown=function(){
    var x=event.clientX;
    var y=event.clientY;
for(var j=0;j<6;j++){
if(x>100*0+14){if(x<100*0+86){alert("x:1");}}break;
if(x>100*1+14){if(x<100*1+86){alert("x:2");}}break;
if(x>100*2+14){if(x<100*2+86){alert("x:3");}}break;
if(x>100*3+14){if(x<100*3+86){alert("x:4");}}break;
if(x>100*4+14){if(x<100*4+86){alert("x:5");}}break;
if(x>100*5+14){if(x<100*5+86){alert("x:6");}}break;
}
for(var k=0;k<6;k++){
if(y>100*0+14){if(y<100*0+86){alert("y:1");}}break;
if(y>100*1+14){if(y<100*1+86){alert("y:2");}}break;
if(y>100*2+14){if(y<100*2+86){alert("y:3");}}break;
if(y>100*3+14){if(y<100*3+86){alert("y:4");}}break;
if(y>100*4+14){if(y<100*4+86){alert("y:5");}}break;
if(y>100*5+14){if(y<100*5+86){alert("y:6");}}break;
}

<script type="text/javascript">
function init(){
var table=document.getElementById("test");
var frag=document.createDocumentFragment;
for(var i=1;i<=6;i++){
var tr=document.createElement("tr");
for(var j=1;j<=7;j++){
var td=document.createElement("td");
td.setAttribute("ij","第"+i+"行第"+j+"列");
td.style.width="100px";
td.innerHTML=i+""+j;
td.onclick=shows;
tr.appendChild(td);
}
table.appendChild(tr);
}
}
function shows(){
alert(this.getAttribute("ij"));
}
window.onload=init;
</script>
</head>

<body>
<table id="test">
</table>
</body>
</html>
这样试试
