在背景色功能下添加背景图像

我有三个功能在我的交互式宠物上运行（更改背景，调光灯，鼠标跟随）。我正在尝试将图像添加到身体背景，但每次尝试时都会将其推到顶部，并且脏/清洁背景功能不起作用。有人能告诉我如何改变下面第一个功能的颜色部分来切换图像而不是颜色代码？我认为这将解决眼前的问题。：/在背景色功能下添加背景图像

CSS代码：

//change background color: dirty/clean tank 
setTimeout(function dirty() { //sets background color to murky green 
document.body.style.backgroundColor = ****"#CCCC99";** //would like this to be an image** 
var btn = document.body.appendChild(document.createElement('button')); 
btn.appendChild(document.createTextNode("Clean the tank!")); 
    document.body.style.marginTop = "-1000px"; 

btn.onclick = function clean() { 
    btn.parentNode.removeChild(btn); 
    document.body.style.backgroundColor = **"#CCFFFF";//would like this to be an image** 
    setTimeout(dirty,27000); //how long it takes to make the tank dirty 
}; 
},500); //first loading of clear blue timeout 


//dim the lights 
var dimmed = 0; 
function toggleLights() 
{ 
var dimmer = document.getElementById("dimmer"); 
if(dimmed == 0) dimmed = 1; 
else dimmed = 0; 

if(dimmed == 1) 
{ 
    dimmer.style.opacity = 0.8; 
    dimmer.style.visibility = "visible"; 
} 

if(dimmed == 0) 
{ 
    dimmer.style.opacity = 0.0; 
    dimmer.style.visibility = "hidden"; 
} 
} 


//fish moves on mouse hover 
$(document).ready(function() { 
$("#swim").mousemove(function (event) { 
var fish = $("#fish1"); 
var position = fish.position(); 
var mousey = event.pageX; 


if (position.left > mousey) { 
    $("#fish1").html("<img src='images/happy.png' />"); 
} else { 
    $("#fish1").html("<img src='images/happyback.png'/>"); 
} 

$("#fish1").stop().animate({ 
    left: event.pageX, 
    top: event.pageY 
}, 300); 
}); 
});

HTML代码：

<HTML> 
<HEAD> 
<TITLE>Untitled</TITLE> 


<link href="style.css" rel="stylesheet" type="text/css" /> 

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript" 
</script> 
<script type="text/javascript" src="pet.js"></script> 
<script type="text/javascript" src="core.js"></script> 

</HEAD> 



<div id="table"> 
<div id="dimmer" onClick="toggleLights()"></div> 
<a href="javascript:toggleLights();"><img src="images/table-lamp.png" height="380px" 
alt="table lamp"></a> 
</div> 


<div id="swim"> 
<div id="fish1"><img src="images/happy.png"/></div> 
</div> 

</BODY> 
</HTML>

添加在你的HTML起始<body>标签，并更改元素类使用JavaScript，而不是样式属性。这样你可以通过CSS文件更好地控制样式。

所以，你会做这样的事情：

document.body.className = 'state1';

而在你的CSS

.state1{ 
    background-image: url(the/image.jpg); 
}

等等...
