下面是运行效果
<style> BODY {FONT-SIZE: 9pt;} table {FONT-SIZE: 9pt;} </style> <input type=checkbox id=checkall onclick=check_all()><label for=checkall>全部选择</label> 线程数：<input type=text id=the_thread value=10 size=2 maxlength=2 style="height:15px; font-size:12px;padding:0px"> <span id=show></span> <span id=result></span>
