电话号码的验证
要求：
(1)电话号码由数字、"("、")"和"-"构成
(2)电话号码为3到8位
(3)如果电话号码中包含有区号，那么区号为三位或四位
(4)区号用"("、")"或"-"和其他部分隔开
(5)移动电话号码为11或12位，如果为12位,那么第一位为0
(6)11位移动电话号码的第一位和第二位为"13"
(7)12位移动电话号码的第二位和第三位为"13"
根据这几条规则，可以与出以下正则表达式：
(^[0-9]{3,4}\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)
<script language="java script">
function PhoneCheck(s) {
var str=s;
var reg=/(^[0-9]{3,4}\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)/
alert(reg.test(str));
}
</script>
<input type=text name="iphone">
<input type=button onclick="PhoneCheck(document.all.iphone.value)" value="Check">
具有在输入非数字字符不回显的效果，即对非数字字符的输入不作反应。

具体的例子：
http://202.119.73.208/NetEAn/com/test/jsprint.htm在每个文本框的onblur事件中调用校验代码,并且每个文本框中onKeyDown事件中写一个enter转tab函数
//回车键换为tab
function enterToTab()
{
if(event.srcElement.type != 'button' && event.srcElement.type != 'textarea'
&& event.keyCode == 13)
{
event.keyCode = 9;
}
}
