备注：常用Js脚本

一、Cookies操作：

代码

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);
};

二、浏览器多语言切换：

代码

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;
}

三、正则表达式颜色值，空值：

代码

function checkColor(str) {
var pattern = / ^#[0-9a-fA-F]{6}$ / ;
if (str.match(pattern) == null )
return null ;
else
return str;
}

 

function replaceSpace(str) {
   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

代码

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);
}

 五、获取兼容浏览器鼠标位置：

代码

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;

 六、获取html元素坐标：

代码

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);

七、关闭弹出页面，无提示对话框:

代码

var winClose: function (){ // 取元素坐标
    window.opener=null;
    window.open("",'_self',"");
    window.close();

}

八、Onload事件注册

代码

function addLoadEvent(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

代码

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;
}

十、四舍五入

代码

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

代码

function FilterNum(str) {
    return str.replace(/\D+/, '');
}

 十三、获取Request Url 参数

代码

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

View Code

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

View Code

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');
