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
