摘要: 网页中一些常见的问题与解决代码
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 onLoad="form.txt.focus()">
<form name="form">
<input name="txt" size="100" value="Mouse点我提交，按Enter也提交" onClick="form.submit()" onKeyDown="if (event.keyCode==13)form.submit()">
</form>
删除时确认

怎样让表单没有凹凸感
<input type=text style="border:1 solid #000000">
或
<input type=text style="border-left:none; 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
http://www.webjx.com/images/logoo.gif" border=0>
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
http://www.webjx.com/images/logoo.gif" onClick="window.open('','','width='+this.width+',height='+this.height)">
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
<script language="JavaScript">
function test(t) {
for (var i=0; i
}
</script>
<table width="300" cellspacing="1" bgcolor="black" onClick="test(this)">
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
<tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
</table>
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。
<script>
function change(radobj){
var obj = document.getElementsByName("radio2");
for(i=0;i
}
}
</script>
<input type=radio name="radio1" onclick=change(this)>222
<input type=radio name="radio2" disabled>222
<input type=radio name="radio2" disabled>222
