我有以下代码用于获取当前日期:
我有以下代码用于获取当前日期:
var month=new Array(12);
month[0]="January";
month[1]="February";
month[2]="March";
month[3]="April";
month[4]="May";
month[5]="June";
month[6]="July";
month[7]="August";
month[8]="September";
month[9]="October";
month[10]="November";
month[11]="December";
var d = new Date();
var curr_date;
if (d.getDate() == 1)
{
curr_date = d.getDate();
}
else
{
curr_date = d.getDate() - 1;
}
var curr_month = d.getMonth() + 1; //months are zero based
var curr_year = d.getFullYear();
var message_day = curr_year + "_" + curr_month + "_" + curr_date;
var sql_day = month[curr_month - 1].substring(0,3) + curr_date.toString() + curr_year.toString();
if (curr_date == "1")
{
document.write(sql_day + " " + message_day);
}
这对于获取当前日期非常有用,但现在如果是新月的开始,我需要获取上个月的最后一天。
现在这将产生:
Feb12012 2012_2_1
但我需要输出的是:Jan312012 2012_1_31
谢谢
