第二步:把如下代碼加入<body>區域中:
<form name=GradForm>
<table border=1><tr><td>

<INPUT type=radio name=setitem value="start" onClick="set(1)" checked>起始色
<input type=text name="start" size=6 value="#FF0000" onChange="newRGB(1,'')">

<input type=text name="end" size=6 value="#0000FF" onChange="newRGB(1,'')">

</td></tr>
