我想实现代码来创建一个宾果游戏应用程序，它在单击按钮时从数组中获取字母。
如何在单击运行按钮时将数组元素(如 array(a,b,c))随机分配给那些 3X3 表格单元格。当我在一行或对 Angular 线上得到像 abc 这样的序列时，我想增加计数值。
我开始了，但我无法实现代码。请问有什么建议吗？
这是我的代码
<html>
<head>
<script>
function run(){
var grid = document.getElementById("grid");
for (var i = 0, row; row = grid.rows[i]; i++){
row.cells[0].textContent = rand();
row.cells[1].textContent = rand();
row.cells[2].textContent = rand();
}
score()
}
function rand(){
var text = new Array();
var possible = "MCS*";
return possible.charAt(Math.floor(Math.random() * possible.length));
}
function score(){
var Row = document.getElementById("grid");
var Cells = Row.getElementsByTagName("td");
alert(Cells[0].innerText);
alert(Cells[1].innerText);
alert(Cells[2].innerText);
alert(Cells[3].innerText);
alert(Cells[5].innerText);
alert(Cells[6].innerText);
alert(Cells[7].innerText);
alert(Cells[8].innerText);
}
</script>
</head>
<body>
<form metdod="post">
<table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse" width="100"v id="grid">
<tr>
<td id="1-1" height="19" width="20%"> </td>
<td id="1-2" height="19" width="20%"> </td>
<td id="1-3" height="19" width="20%"> </td>
</tr>
<tr>
<td id="2-1" height="16" width="20%"> </td>
<td id="2-2" height="16" width="20%"> </td>
<td id="2-3" height="16" width="20%"> </td>
</tr>
<tr>
<td id="3-1" height="19" width="20%"> </td>
<td id="3-2" height="19" width="20%"> </td>
<td id="3-3" height="19" width="20%"> </td>
</tr>
</table>
<br><br>
<input type="button" onClick="return run();" value="run">
</form>
</body>
</html>
