<script type="text/javascript">
// var regTel = ^(1[3|4|5|8]\d{9}$/; //单个手机
var regTel = /^(1[3|4|5|8]\d{9}\,)*(1[3|4|5|8]\d{9})$/;
if ($("#txtPhone").val() == "") {
alert("请填写手机！");

前台页面js中要获取url参数时候
var Request = new QueryString();
function QueryString() {
var name,value,i;
var str = location.href;
var num = str.indexOf("?")
str = str.substr(num + 1);
var arrtmp = str.split("&");
for (i = 0; i < arrtmp.length; i++) {
num = arrtmp[i].indexOf("=");
if (num > 0) {
name = arrtmp[i].substring(0,num);
value = arrtmp[i].substr(num + 1);
this[name] = value;
}
}
}
引用完后可以在脚本中直接用Request["参数"]
实时显示时间
<script type="text/javascript">
$(function () {
clock();
});
//e实时显示时间
function clock() {
var d = new Date()
var year = d.getFullYear();
var month = d.getMonth() + 1;
var day = d.getDate();
var hours = d.getHours();
var minutes = d.getMinutes();
var Seconds = d.getSeconds();
var num = (year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + Seconds).split(' ');
var num1 = num[0].split('-');
var num2 = num[1].split(':');
var d = new Date(num1[0],num1[1],num1[2],num2[0],num2[1],num2[2]);
var t = d.getTime();
t += 1000;
var date = new Date(t);
var year = date.getFullYear();
var month = date.getMonth();
var day = date.getDate();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
var months = new Array("","1","2","3","4","5","6","7","8","9","10","11","12");
var monthname = months[month];
if (hour > 24) {
hour = hour - 12;
}
if (monthname < 10)
monthname = "0" + monthname;
if (day < 10)
day = "0" + day;
if (minute < 10) {
minute = "0" + minute;
}
if (second < 10) {
second = "0" + second;
}
$("#txtTime").val(year + "-" + monthname + "-" + day + " " + hour + ":" + minute + ":" + second);
setTimeout("clock()",1000);
}
