ttt.js如下：

function isblank(n)
{
if(owns("player",n)||owns("computer",n)
{
return false;
}
return true;
}

function owns(who,i)
{
var fr=parent.parent.frames[1];
var doc=fr.document;
var field=doc.forms[0].element[i];
if(field==null||field.value=who)
{
return true;

}
Else
{
return false;
}
}

function setowner(who,n)
{
var fr=parent.parent.frames[1];
var doc=fr.document;
var field=doc.forms[0].element[n];
field.value=who;

}

function tictactoe(who,n1,n2,n3)
{
if(owns(who,n1)&&owns(who,n2)&&owns(who,n3))
{
var color=parent.frames[0].document.bgcolor;
for(var i=0;i<9;i++)
{
parent.frames[i].document.bgcolor="black";
parent.frames[n1].document.bgcolor=color;
parent.frames[n2].document.bgcolor=color;
parent.frames[n3].document.bgcolor=color;
return ture;

}
}
return false;

}

function istictactoe(who)
{
if(tictactoe(who,0,1,2))
return true;
if(tictactoe(who,3,4,5))
return true;
if(tictactoe(who,6,7,8))
return true;
if(tictactoe(who,0,3,6))

var moved=false;
while(!moved)
{
var newmove=Math.round(9*Math.random());
if (isblank(newmove))
{
setowner("computer",newmove);
var fr=parent.frames[newmove];
fr.location.href="x.html";

}
}

}
