只能输入数字正则
<input onKeyUp="value=value.replace(/\D+/g,'')">

只能输入中文正则
<input onKeyUp="value=value.replace(/[ -}]/g,'')">

让英文字符串超出表格宽度自动换行
word-wrap: break-word; word-break: break-all;

用回车提交表单
<body >
<form name="form">
<input name="txt" size="100" value="Mouse点我提交，按Enter也提交" >
</form>

删除时确认

怎样让表单没有凹凸感
<input type=text solid #000000">
或
<input type=text border-right:none; border-top:none; border-bottom: 1 solid #000000"></textarea>

怎样去掉图片链接点击后，图片周围的虚线

子窗口刷新父窗口

window.opener.location.reload()

打开一个新的窗口，而窗口的宽度和高度则是这个图片的实际的高和宽

弹出的窗口居中
<script>
myWin=window.open("about:blank","","width=200,height=160");
myWin.moveTo(screen.width/2-100,screen.height/2-80);
</script>

单击表格中某个单元格则这个单元格变颜色

单选框问题

有三个单选框，
<input type=radio name=1>222
<input type=radio name=2>222
<input type=radio name=3>222
怎么样使选中第一个后才能选择下面两个中的一个。

tbody区域滚动条
