您好,我有这个代码,这是一个内存棋盘游戏。我想知道是否可以改变字母和放置图像。我是javaScript的新手,我正在尝试通过编辑和理解开源代码来学习..任何帮助都将不胜感激,谢谢!
这是Javscript代码:
var memory_array = ['A','A','B','B','C','C','D','D','E','E','F','F','G','G','H','H','I','I','J','J','K','K','L','L'];
var memory_values = [];
var memory_tile_ids = [];
var tiles_flipped = 0;
Array.prototype.memory_tile_shuffle = function(){
var i = this.length, j, temp;
while(--i > 0){
j = Math.floor(Math.random() * (i+1));
temp = this[j];
this[j] = this[i];
this[i] = temp;
}
}
function newBoard(){
tiles_flipped = 0;
var output = '';
memory_array.memory_tile_shuffle();
for(var i = 0; i < memory_array.length; i++){
output += '<div id="tile_'+i+'" onclick="memoryFlipTile(this,\''+memory_array[i]+'\')"></div>';
}
document.getElementById('memory_board').innerHTML = output;
}
function memoryFlipTile(tile,val){
if(tile.innerHTML == "" && memory_values.length < 2){
tile.style.background = '#FFF';
tile.innerHTML = val;
if(memory_values.length == 0){
memory_values.push(val);
memory_tile_ids.push(tile.id);
} else if(memory_values.length == 1){
memory_values.push(val);
memory_tile_ids.push(tile.id);
if(memory_values[0] == memory_values[1]){
tiles_flipped += 2;
// Clear both arrays
memory_values = [];
memory_tile_ids = [];
// Check to see if the whole board is cleared
if(tiles_flipped == memory_array.length){
alert("Board cleared... generating new board");
document.getElementById('memory_board').innerHTML = "";
newBoard();
}
} else {
function flip2Back(){
// Flip the 2 tiles back over
var tile_1 = document.getElementById(memory_tile_ids[0]);
var tile_2 = document.getElementById(memory_tile_ids[1]);
tile_1.style.background = 'url(images/logo.jpg) no-repeat';
tile_1.innerHTML = "";
tile_2.style.background = 'url(images/logo.jpg) no-repeat';
tile_2.innerHTML = "";
// Clear both arrays
memory_values = [];
memory_tile_ids = [];
}
setTimeout(flip2Back, 700);
}
}
}
}
这是HTML代码
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>The HTML5 Herald</title>
<link rel="stylesheet" type="text/css" href="style.css">
<script src="script.js"></script>
</head>
<body>
<div id="memory_board"> </div>
<script> newBoard(); </script>
</body>
</html>
最后这是CSS代码
div#memory_board{
background: #CCC;
border: #999 1px solid;
width: 800px;
height: 540px;
padding: 24px;
margin: 0px auto;
}
div#memory_board > div{
background: url(images/logo.jpg) no-repeat;
border: #000 1px solid;
width: 71px;
height: 71px;
float: left;
margin: 10px;
padding: 20px;
font-size: 64px;
cursor: pointer;
text-align:center;
}
答案 0 :(得分:2)
简单的方法来更改代码以执行您想要的操作 - 而不是
tile.innerHTML = val;
做的:
tile.innerHTML = '<img src="' + val + '.png"/>';
如果你在与index.html相同的位置有A.png,B.png等,它应该可以使用。
如果你想更深入地了解它,我写了一篇tutorial关于用html5框架做这件事的事情(道歉链接到我们自己的网站)
