Some simple examples, using native js and jQuery to change div attributes and reset them at will. The code is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>函数传参，改变Div任意属性的值</title>
<style type="text/css">
body,p{margin:0;padding:0;}
body{color:#333;font:12px/1.5 Tahoma;padding-top:10px;}
#outer{width:300px;margin:0 auto;}
p{margin-bottom:10px;}
button{margin-right:5px;}
label{width:5em;display:inline-block;text-align:right;}
input{padding:3px;font-family:inherit;border:1px solid #ccc;}
#div1{color:#fff;width:180px;height:180px;background:#000;margin:0 auto;padding:10px;}
</style>
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>函数传参，改变Div任意属性的值</title>
<style type="text/css">
body,p{margin:0;padding:0;}
body{color:#333;font:12px/1.5 Tahoma;padding-top:10px;}
#outer{width:300px;margin:0 auto;}
p{margin-bottom:10px;}
button{margin-right:5px;}
label{width:5em;display:inline-block;text-align:right;}
input{padding:3px;font-family:inherit;border:1px solid #ccc;}
#div1{color:#fff;width:180px;height:180px;background:#000;margin:0 auto;padding:10px;}
</style>
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
/*var changeSytle = function (elem,name,value){
elem.style[name] = value;
}
window.onload = function (){
var oDiv = document.getElementById("div1");
var oBtn = document.getElementsByTagName("button");
var oInput = document.getElementsByTagName("input");
oBtn[0].onclick = function (){
changeSytle (oDiv,oInput[0].value,oInput[1].value)
} ,
oBtn[1].onclick = function (){
oDiv.removeAttribute("style");
}
} */原生js部分实现


$(function(){
$("button:first").click(function(){
var styleName= $("#outer").find("input:first").val();
var styleVal = $("#outer").find("input:last").val();
$("#div1").css(styleName,styleVal);
})
$("button:last").click(function(){
$("#div1").removeAttr("style");
})
})

</script>

</head>
<body>
<div id="outer">
<p><label>属性名：</label><input type="text" value="background" name="styleName" /></p>
<p><label>属性值：</label><input type="text" value="blue" name="val" /></p>
<p><label></label><button>确定</button><button>重置</button></p>
</div>
<div id="div1">在上方输入框输入"属性名"及"属性值"，点击确定按钮查看效果。</div>

</body>
</html>
$(function(){
$("button:first").click(function(){
var styleName= $("#outer").find("input:first").val();
var styleVal = $("#outer").find("input:last").val();
$("#div1").css(styleName,styleVal);
})
$("button:last").click(function(){
$("#div1").removeAttr("style");
})
})

</script>

</head>
<body>
<div id="outer">
<p><label>属性名：</label><input type="text" value="background" name="styleName" /></p>
<p><label>属性值：</label><input type="text" value="blue" name="val" /></p>
<p><label></label><button>确定</button><button>重置</button></p>
</div>
<div id="div1">在上方输入框输入"属性名"及"属性值"，点击确定按钮查看效果。</div>
