脚本说明:
第一步:把如下代码加入<head>区域中
<script>
function ShowMenu(bMenu) {
document.all.idFinder.style.display = (bMenu) ? "none" : "block" 
document.all.idMenu.style.display = (bMenu) ? "block" : "none"
idML.className = (bMenu) ? "cOn" : "cOff"
idRL.className = (bMenu) ? "cOff" : "cOn"
return false
}
</script>

第二步:把如下代码加入<body>区
<script>
    var size=10
    var moves = 0
    var off = size*2
    var on = 0
    var current = null
    function doOver() {

        if (current!=null)
          current.style.backgroundColor = current._background
        event.srcElement._background = event.srcElement.style.backgroundColor
        event.srcElement.style.backgroundColor = "lightgrey"
        current = event.srcElement
      }
    }

function setColor(el) {
      if ((el._background=="") || (el._background==null)) {
        el.style.backgroundColor = "yellow"
        el._background = "yellow" 
      } else {
        el.style.backgroundColor = ""
        el._background = "" 
      }
    }

function countLights() {
      off = 0; on = 0
      for (var x=0; x < size; x++) 
        for (var y=0; y < size; y++) {
          var p = board.rows[x].cells[y]
          if (p._background=="yellow")
            on++
          else
            off ++
        }
        document.all.on.innerText = on
      if (off!=0)     
        document.all.off.innerText = off
      else
        document.all.off.innerText = "You Win!"
      return (off==0)
    }

function doClick() {
      setColor(current)     
      var cellIdx = current.cellIndex
      var rowIdx = current.parentElement.rowIndex
      if (rowIdx>0) 
        setColor(board.rows[rowIdx-1].cells[cellIdx])
      if (rowIdx<size-1)
        setColor(board.rows[rowIdx+1].cells[cellIdx])
      if (cellIdx>0) 
        setColor(board.rows[rowIdx].cells[cellIdx-1])
      if (cellIdx<size-1)
        setColor(board.rows[rowIdx].cells[cellIdx+1])
      moves++
      document.all.moves.innerText = moves
      win = countLights()
      if (win) {
        board.onclick = null
        board.onmouseover = null
        current.style.background = "yellow"
      }
    }

function newGame() {
      size = document.all.gameSize.value
      if (size<3)
        size=3
      if (size>15)
        size=15
      document.all.gameSize.value = size
      document.all.board.outerHTML = buildBoard()
      moves=0
      document.all.moves.innerText = moves
      countLights()
