一、Cookies操作：
function clearCookie() {
var now =new Date();
var yesterday =new Date(now.getTime() -1000*60*60*24);
this.setCookie('co'+this.obj, 'cookieValue', yesterday);
this.setCookie('cs'+this.obj, 'cookieValue', yesterday);
this.setCookie('keep', 'cookieValue', yesterday);
};
function setCookie(cookieName, cookieValue, expires, path, domain, secure) {
document.cookie =
escape(cookieName) +'='+ escape(cookieValue)
+ (expires ?'; expires='+ expires.toGMTString() : '')
+ (path ?'; path='+ path : '')
+ (domain ?'; domain='+ domain : '')
+ (secure ?'; secure' : '');
};
function getCookie(cookieName) {
var cookieValue ='';
var posName = document.cookie.indexOf(escape(cookieName) +'=');
if (posName !=-1) {
var posValue = posName + (escape(cookieName) +'=').length;
var endPos = document.cookie.indexOf(';', posValue);
if (endPos !=-1) cookieValue = unescape(document.cookie.substring(posValue, endPos));
else cookieValue = unescape(document.cookie.substring(posValue));
}
return (cookieValue);
};
var now =new Date();
var yesterday =new Date(now.getTime() -1000*60*60*24);
this.setCookie('co'+this.obj, 'cookieValue', yesterday);
this.setCookie('cs'+this.obj, 'cookieValue', yesterday);
this.setCookie('keep', 'cookieValue', yesterday);
};
function setCookie(cookieName, cookieValue, expires, path, domain, secure) {
document.cookie =
escape(cookieName) +'='+ escape(cookieValue)
+ (expires ?'; expires='+ expires.toGMTString() : '')
+ (path ?'; path='+ path : '')
+ (domain ?'; domain='+ domain : '')
+ (secure ?'; secure' : '');
};
function getCookie(cookieName) {
var cookieValue ='';
var posName = document.cookie.indexOf(escape(cookieName) +'=');
if (posName !=-1) {
var posValue = posName + (escape(cookieName) +'=').length;
var endPos = document.cookie.indexOf(';', posValue);
if (endPos !=-1) cookieValue = unescape(document.cookie.substring(posValue, endPos));
else cookieValue = unescape(document.cookie.substring(posValue));
}
return (cookieValue);
};
二、浏览器多语言切换：
function ChangeLang() {
if(document.documentElement.lang =='en-us') {
javascript:OnLangSelectionChange(2052);
} else {
javascript:OnLangSelectionChange(1033);
}
}
function OnLangSelectionChange(value)
{
var today =new Date();
var oneYear =new Date(today.getTime() +365*24*60*60*1000);
var url = window.location.href;
document.cookie ='lcid='+ value +';path=/;expires='+ oneYear.toGMTString();
window.location.href = url;
}
if(document.documentElement.lang =='en-us') {
javascript:OnLangSelectionChange(2052);
} else {
javascript:OnLangSelectionChange(1033);
}
}
function OnLangSelectionChange(value)
{
var today =new Date();
var oneYear =new Date(today.getTime() +365*24*60*60*1000);
var url = window.location.href;
document.cookie ='lcid='+ value +';path=/;expires='+ oneYear.toGMTString();
window.location.href = url;
}
三、正则表达式颜色值，空值：
function checkColor(str) {
var pattern =/^#[0-9a-fA-F]{6}$/;
if (str.match(pattern) ==null)
returnnull;
else
returnstr;
}
var pattern =/^#[0-9a-fA-F]{6}$/;
if (str.match(pattern) ==null)
returnnull;
else
returnstr;
}
function replaceSpace(str) {
if (str ==null)
returnnull;
else
return str.replace(/\s/g, '');
}
if (str ==null)
returnnull;
else
return str.replace(/\s/g, '');
}
四、判断是否是数值,验证Email,判断手机号
function IsNumber(fData)
{
var reg =new RegExp("^[-]?[0-9]+[\.]?[0-9]+$");
return reg.test(fData)
}
function IsEmail(fData)
{
var reg =new RegExp("^[0-9a-zA-Z]+@[0-9a-zA-Z]+[\.]{1}[0-9a-zA-Z]+[\.]?[0-9a-zA-Z]+$");
return reg.test(fData);
}
function IsPhone(fData)
{
var reg =/^(\+86)?(1[0-9]{10})$/;
return reg.test(fData);
}
{
var reg =new RegExp("^[-]?[0-9]+[\.]?[0-9]+$");
return reg.test(fData)
}
function IsEmail(fData)
{
var reg =new RegExp("^[0-9a-zA-Z]+@[0-9a-zA-Z]+[\.]{1}[0-9a-zA-Z]+[\.]?[0-9a-zA-Z]+$");
return reg.test(fData);
}
function IsPhone(fData)
{
var reg =/^(\+86)?(1[0-9]{10})$/;
return reg.test(fData);
}
五、获取兼容浏览器鼠标位置：
var mousePos;
function mouseMove(ev) {
ev = ev || window.event;
mousePos = mouseCoords(ev);
}
function mouseCoords(ev) {
if (ev.pageX || ev.pageY) {
return { x: ev.pageX, y: ev.pageY };
}
return {
x: ev.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft),
y: ev.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop)
};
}
document.onmousemove = mouseMove;
function mouseMove(ev) {
ev = ev || window.event;
mousePos = mouseCoords(ev);
}
function mouseCoords(ev) {
if (ev.pageX || ev.pageY) {
return { x: ev.pageX, y: ev.pageY };
}
return {
x: ev.clientX + (document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft),
y: ev.clientY + (document.documentElement.scrollTop ? document.documentElement.scrollTop : document.body.scrollTop)
};
}
document.onmousemove = mouseMove;
六、获取html元素坐标：
var getPos:function(o){//取元素坐标
var x =0, y =0;
do{
x += o.offsetLeft;
y += o.offsetTop;
}while(o=o.offsetParent);
return {'x':x,'y':y};
}
var pos=getPos(obj);
alert(pos.x);
var x =0, y =0;
do{
x += o.offsetLeft;
y += o.offsetTop;
}while(o=o.offsetParent);
return {'x':x,'y':y};
}
var pos=getPos(obj);
alert(pos.x);
七、关闭弹出页面，无提示对话框:
var winClose:function(){//取元素坐标
window.opener=null;
window.open("",'_self',"");
window.close();
window.opener=null;
window.open("",'_self',"");
window.close();
}
八、Onload事件注册
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload !='function') {
window.onload = func;
} else {
window.onload =function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
var oldonload = window.onload;
if (typeof window.onload !='function') {
window.onload = func;
} else {
window.onload =function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
九、计算两个时间差
function DateDiff(sdt,edt)
{
var s=new Date(sdt);
var e=new Date(edt);//Days
var df=(endDate.getTime()-startDate.getTime())/3600/1000/24;
return dt;
}
{
var s=new Date(sdt);
var e=new Date(edt);//Days
var df=(endDate.getTime()-startDate.getTime())/3600/1000/24;
return dt;
}
十、四舍五入
function ForDight(Dight,How)
{
var c=Math.pow(10,How);
return Math.round(Dight*c)/c;
}
十一、自动滚到页面底部
<body onload="scrollTo(0,document.body.scrollHeight)">
十二、去除其他符号，得到数字
function FilterNum(str) {
return str.replace(/\D+/, '');
}
十三、获取Request Url 参数
function getQry(key){
var search=location.search.slice(1);//得到get方式提交的查询字符串
var arr=search.split("&");
for(var i=0;i<arr.length;i++){
var ar=arr[i].split("=");
if(ar[0]==key){
return ar[1];
}
}
}
十四、弹出对话框页面
function OpenNewWindow(pageUrl) {
var lanTitle = 'Add a new task.';
var options = {
url: pageUrl,
title: lanTitle,
allowMaximize: false,
showClose: true,
dialogReturnValueCallback: demoCallback
};
function demoCallback() {
SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);
}
SP.UI.ModalDialog.showModalDialog(options);
}
十五、获取URL参数值
var str = location.search.match(/xmbh=[^&]+/)[1];
var id = location.search.match(/ID=(\d+)/)[1];
十六、关闭页面时提示
//添加提示 $(window).bind('beforeunload', function () { return 'Are you sure to leave this page? The unsaved data will be lost!'; }); //提交时解除提示 $(window).unbind('beforeunload');
