JavaScript实现手机号格式校验与登录拦截

<form method="post" action="login.php" onsubmit="return abc()">
 <input type="text" id="phone" />
 <input type="submit" value="登录"/> </form>
<script type="text/javascript">
function abc() {
 var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+\d{8})$/;
 if(!myreg.test($("#phone").val()))
 {
  alert('请输入有效的手机号码！');
  return false;
 }
 callback();
}
</script>

/^13d{9}$/g||/^15[8,9]d{8}$/g
