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：

代码

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

四、正则表达式空值：

function replaceSpace(str) {
            if (str == null)
                return null;
            else
                return str.replace(/\s/g, '');
        }
