////使用方法
//var now = new Date();
//var nowStr = now.format("yyyy-MM-dd hh:mm:ss");
////使用方法2:
//var testDate = new Date();
//var testStr = testDate.format("YYYY年MM月dd日hh小时mm分ss秒");
//alert(testStr);
////示例：
//alert(new Date().format("yyyy年MM月dd日"));
//alert(new Date().format("MM/dd/yyyy"));
//alert(new Date().format("yyyyMMdd"));
//alert(new Date().format("yyyy-MM-dd hh:mm:ss"));
