JSで書かれた数字パズルゲームのコード【学習参考書】_javascriptスキル

复制代码代码如下:

<頭>



td.numTd{
幅 : 20px ;
高さ: 20px ;
}

div.numDiv{
幅 : 100% ;
高さ: 100% ;
背景色: #000 ;
色: #FFF ;
テキスト整列 : 中央;
vertical-align : 中央;
}

var currPos = 9;
function move(event){
switch(event.keyCode){
case 37 :
// 左键
if (currPos % 3 != 0){
var currTd = document.getElementById("numTd_" currPos);
var nextTd = document.getElementById("numTd_" (currPos 1));
var temp = nextTd.innerHTML;
nextTd.innerHTML = " ";
currTd.innerHTML = temp;
現在の位置 ;
}
休憩;
ケース 38 :
// 上键
if (currPos var currTd = document.getElementById("numTd_" currPos);
var nextTd = document.getElementById("numTd_" (currPos 3));
var temp = nextTd.innerHTML;
nextTd.innerHTML = " ";

case 39 :
// 右键
if (currPos % 3 != 1){

var nextTd = document.getElementById("numTd_" (currPos - 1));
var temp = nextTd.innerHTML;
nextTd.innerHTML = " ";
currTd.innerHTML = temp;
currPos -- ;
}
休憩;
case 40 :
// 下键
if (currPos > 3){
var currTd = document.getElementById("numTd_" currPos);
var nextTd = document.getElementById("numTd_" (currPos - 3));
var temp = nextTd.innerHTML;
nextTd.innerHTML = " ";
currTd.innerHTML = temp;
currPos -= 3;
}
休憩;

ブレーク;
}

if (isWin()){
alert("恭喜你，过关了！");

}

}

function isWin(){
for (i = 1; i var numTd = document.getElementById(" numTd_" i);

true を返します。

フラグ = false;
}

var len = newNumArr.length;

" newNumArr[j] "

";
}
else{
document.getElementById("numTd_" (j 1)).innerHTML = " ";
currPos = j 1;
}
}

// document.getElementById("output").innerText = newNumArr;
}

関数 inverNum(numArr){
var len = numArr.length;
変数カウント = 0;
for(i = 0; i for(j = i 1; j if (numArr[j] > numArr[ i]){
カウント ;
}
}
}

戻り数;
