1、用DoJo实现数值微调器
NumberSpinner.html：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>数值微调器</title>
<link rel="stylesheet" type="text/css" href="dojoroot/dojo/resources/dojo.css">
<link rel="stylesheet" type="text/css" href="dojoroot/dijit/themes/tundra/tundra.css">
<script type="text/javascript" src="dojoroot/dojo/dojo.js" djConfig="parseOnLoad:true"></script>
<style type="text/css">
.form_body{
20%;
background-color: #CCCCCC;
padding: 10px 10px 10px 10px;
}
label {
font-weight: bold;
color: #FF0000;
}
</style>
<script type="text/javascript">
dojo.require("dojo.parser");
dojo.require("dijit.form.Form");
dojo.require("dijit.form.Button");
dojo.require("dijit.form.NumberSpinner");
</script>
<script type="dojo/method">
dojo.mixin(this,{
reset:function(){
this.setValue(0);
}
});
</script>
</head>
<body class="tundra">
<form dojoType="dijit.form.Form" class="form_body">
<label for="number">数值微调器：</label>
<input dojoType="dijit.form.NumberSpinner" constraints="{min:-100,max:100}" value=0/>
<br/><br/>
<label for="numberSpinner">数值微调器：</label>
<input dojoType="dijit.form.NumberSpinner" constraints="{min:-100,max:100}" jsId="numberSp"
value=0/>
<br/><br/>
<button dojoType="dijit.form.Button" οnclick="numberSp.reset()">重置</button>
</form>
</body>
</html>2、运行项目是，Tomcat运行后出现：

七月 10, 2013 12:33:24 上午 org.apache.catalina.startup.Catalina start
信息: Server startup in 1388 ms
这个是严重警告，对项目运行没有影响，关键之处是把JS和CSS引入的路径弄错了，导致结果显示不出来！
3、运行结果如图所示：
（1）未点击任何按钮
（2）点击上下按钮
（3）点击“重置”按钮
