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{
   width: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/>
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
    <button dojoType="dijit.form.Button" onclick="numberSp.reset()">重置</button>
 </form>
</body>
</html>

2、运行项目是，Tomcat运行后出现：

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
