电话号码的验证
要求：
　　(1)电话号码由数字、(、screen.width/2)this.width=screen.width/2 vspace=2 border=0>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(、screen.width/2)this.width=screen.width/2 vspace=2 border=0>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=javascript>
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));
}

<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。
