日期格式化和数字价格化

方式一: 
formateNumber(num) { if ((num + "").trim() == "") { return ""; } if (isNaN(num)) { return num; } num = num + ""; if (/^.*\..*$/.test(num)) { var pointIndex = num.lastIndexOf("."); var intPart = num.substring(0, pointIndex); var pointPart = num.substring(pointIndex + 1, num.length); intPart = intPart + ""; var re = /(-?\d+)(\d{3})/ while (re.test(intPart)) { intPart = intPart.replace(re, "$1,$2") } num = intPart + "." + pointPart; } else { num = num + ""; var re = /(-?\d+)(\d{3})/ while (re.test(num)) { num = num.replace(re, "$1,$2") } } return num; },
方式二:

location.hostname.replace(/.*?([^\.]+.(com|cn))/, "$1"); //www.baidu.com => baidu.com
return (num || 0).toString().replace(/(\d)(?=(?:\d{3})+$)/g, '$1,') //数字三个三个逗号分隔


日期格式: formateDate(value,mask) { var d = new Date(Date.parse(value)); var regular=mask||"yyyy-MM-dd"; var zeroize = function (value, length) { if (!length) length = 2; value = String(value); for (var i = 0, zeros = ''; i < (length - value.length); i++) { zeros += '0'; } return zeros + value; }; return regular.replace(/"[^"]*"|'[^']*'|\b(?:d{1,4}|m{1,4}|yy(?:yy)?|([hHMstT])\1?|[lLZ])\b/g, function ($0) { switch ($0) { case 'd': return d.getDate(); case 'dd': return zeroize(d.getDate()); case 'ddd': return ['Sun', 'Mon', 'Tue', 'Wed', 'Thr', 'Fri', 'Sat'][d.getDay()]; case 'dddd': return ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'][d.getDay()]; case 'M': return d.getMonth() + 1; case 'MM': return zeroize(d.getMonth() + 1); case 'MMM': return ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'][d.getMonth()]; case 'MMMM': return ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'][d.getMonth()]; case 'yy': return String(d.getFullYear()).substr(2); case 'yyyy': return d.getFullYear(); case 'h': return d.getHours() % 12 || 12; case 'hh': return zeroize(d.getHours() % 12 || 12); case 'H': return d.getHours(); case 'HH': return zeroize(d.getHours()); case 'm': return d.getMinutes(); case 'mm': return zeroize(d.getMinutes()); case 's': return d.getSeconds(); case 'ss': return zeroize(d.getSeconds()); case 'l': return zeroize(d.getMilliseconds(), 3); case 'L': var m = d.getMilliseconds(); if (m > 99) m = Math.round(m / 10); return zeroize(m); case 'tt': return d.getHours() < 12 ? 'am' : 'pm'; case 'TT': return d.getHours() < 12 ? 'AM' : 'PM'; case 'Z': return d.toUTCString().match(/[A-Z]+$/); // Return quoted strings with the surrounding quotes removed default: return $0.substr(1, $0.length - 2); } }); }
