代码如下：

<script language="javascript"> //校验普通电话、传真号码：可以“+”开头，除数字外，可含有“-” //edit by function isTel(object) { var s =document.getElementById(object.id).value; //电话和手机号码验证 var pattern =/^((\d{11})|^((\d{7,8})|(\d{4}|\d{3})-(\d{7,8})|(\d{4}|\d{3})-(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1})|(\d{7,8})-(\d{4}|\d{3}|\d{2}|\d{1}))$)/; // var pattern =/^(([0\+]\d{2,3}-)?(0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/; //var pattern =/(^[0-9]{3,4}\-[0-9]{7,8}$)|(^[0-9]{7,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)/; if(s!="") { if(!pattern.exec(s)) { alert('请检查电话号码是否输入有误'); object.value=""; object.focus(); } } else { alert('电话号码不能为空'); } } </script>
