1、字符串全部替换:
- String.prototype.replaceAll = function(s1,s2){
- return this.replace(new RegExp(s1,"gm"),s2);
- }
2、时间格式化:
- Date.prototype.Format = function(fmt) { //author: meizz
- var o = {
- "M+": this.getMonth() + 1,
- //月份
- "d+": this.getDate(),
- //日
- "h+": this.getHours(),
- //小时
- "m+": this.getMinutes(),
- //分
- "s+": this.getSeconds(),
- //秒
- "q+": Math.floor((this.getMonth() + 3) / 3),
- //季度
- "S": this.getMilliseconds() //毫秒
- };
- if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
- for (var k in o) if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
- return fmt;
- };
String.prototype.replaceAll = function(s1,s2){return this.replace(new RegExp(s1,"gm"),s2); }
