jQuery用ID在每一行中选择第三、第四和第五个TD

使用children()遍历tr和td以获得所需的值。另一种方法是:

var i = 0;
$('table[id^=game] tr td').each(function() {
 switch(i) {
  case 0: { alert("First TD:" + $(this).html()); break; }
  case 1: { alert("Second TD:" + $(this).html()); break; }
  // ...
 }
 i++;
});

如果你有osme示例表,会更容易。

nth Child selector

$('table[id^=game] tr td:nth-child(3)'); // would select all cells that were in the 3rd column
