废话不多说，直接看代码：
1.非空验证
function isNotEmpty(str){
if(str==null)
{
return false;
}
if(typeof(str)=='undefined'){
return false;
}
if(str.replace("/(^s*)|(s*$)/g", "").length ==0){
return false;
}
return true;
}
2. //跳过工作日后N天：即当前日期后n天，有周六周末则跳过不算在n内
function getWorkNDayAfter(datetime,num){
var date = new Date(datetime);
date = new Date(+date + 1000*60*60*24);
if(date.getDay()%6 !=0){
num--;
}
if(num<=0){
return date;
}else{
return getWorkNDayAfter(date,num);
}
}
3. //屏蔽空格和非数字
function formatInput(srcEle){
var _val = srcEle.value;
_val = _val.replace(/\s/g,'');
_val = _val.replace(/[\D]/g,'');
srcEle.value = _val;
}
4.//下月第一天
function showMonthFirstDay()
{
var applyDate = $("#deduct_date").val();
var Nowdate=new Date(applyDate);
Nowdate.setDate(Nowdate.getDate()+1);
return Nowdate;
}
//下周第一天
function showNextFirstWeekDay()
{
var applyDate = $("#deduct_date").val();
var Nowdate=new Date(applyDate);
var WeekFirstDay=new Date(Nowdate-(Nowdate.getDay()-1)*86400000);
var WeekLastDay=new Date((WeekFirstDay/1000+6*86400)*1000);
return new Date((WeekLastDay/1000+86400)*1000);
}
5.//增加身份证验证
function isIdCardNo(num) {
// 身份证号码为15位或者18位，15位时全为数字，18位前17位为数字，最后一位是校验位，可能为数字或字符X
var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X)$)/;
var cert_type=$('#c_cert_type').val();
if(cert_type=='1'){
if(reg.test(num) === false)
{
return false;
}
var tmpStr = "";
if (num.length == 15) {
tmpStr = num.substring(6, 12);
tmpStr = "19" + tmpStr;
tmpStr = tmpStr.substring(0, 4) + "-" + tmpStr.substring(4, 6) + "-" + tmpStr.substring(6)
} else {
tmpStr = num.substring(6, 14);
tmpStr = tmpStr.substring(0, 4) + "-" + tmpStr.substring(4, 6) + "-" + tmpStr.substring(6)
}
if(!tmpStr.isDate()){
$("#c_birthday").val("");
return false;
}
$("#c_birthday").val(tmpStr);
if(num.substring(num.length-2,num.length-1)%2==0){
jsSelectItemByValue(document.getElementById("c_sex"),2);
}else{
jsSelectItemByValue(document.getElementById("c_sex"),1);
}
if (num.length == 18){
var arrExp = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2];//加权因子
var arrValid = [1, 0, "X", 9, 8, 7, 6, 5, 4, 3, 2];//校验码
var sum = 0, idx;
for(var i = 0; i < num.length - 1; i++){
// 对前17位数字与权值乘积求和
sum += parseInt(num.substr(i, 1), 10) * arrExp[i];
}
// 计算模（固定算法）
idx = sum % 11;
// 检验第18为是否与校验码相等
return arrValid[idx] == num.substr(17, 1).toUpperCase();
}
}
return true;
}
//邮编验证
function industry(num) {
var reg = /(^[0-9]{0,8}$)|(^无$)/;
if(reg.test(num) === false)
{
return false;
}
return true;
}
//手机号码验证
function isMobile(num) {
var reg = /^1[3-8]\d{9}$/;
if(reg.test(num) === false)
{
return false;
}
return true;
}
