javascript常见操作汇总

/***** BasePage.js 公共的 脚本文件 部分方法需引用jquery库 *****/ //#region 日期操作 //字符串转化为时间。function stringtoTime(date1) {  var dt = new Date(Date.parse(date1.replace(/-/g, "/")));  return dt;} // 使用 var date1 = "2013-06-08 15:23:31"或"2013/6/8 9:9:00"格式;//-------------------------------------------------------------// 日期格式化Date.prototype.format = function (format) {  var o = {    "M+": this.getMonth() + 1, //month     "d+": this.getDate(), //day     "h+": this.getHours(), //hour     "m+": this.getMinutes(), //minute     "s+": this.getSeconds(), //second     "q+": Math.floor((this.getMonth() + 3) / 3), //quarter     "S": this.getMilliseconds() //millisecond   }   if (/(y+)/.test(format)) {    format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
