日期时间格式化方法，可以格式化年、月、日、时、分、秒、周

Date.prototype.Format = function (formatStr) {
var week = ['日', '一', '二', '三', '四', '五', '六'];
return formatStr.replace(/yyyy|YYYY/, this.getFullYear())
.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100))
.replace(/MM/, (this.getMonth() + 1) > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1)).replace(/M/g, (this.getMonth() + 1))
.replace(/w|W/g, week[this.getDay()])
.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate()).replace(/d|D/g, this.getDate())
.replace(/HH|hh/g, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours()).replace(/H|h/g, this.getHours())
.replace(/mm/g, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes()).replace(/m/g, this.getMinutes())
.replace(/ss/g, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds()).replace(/S|s/g, this.getSeconds());
};

eval("new " + data.Rows[i].Occurdt.split('/')[1]).Format("yyyy-MM-dd HH:mm:ss")
