这是我的代码：代码用于获取服务器端的值，所以我想将日期转换为字符串格式然后我调用脚本文件中的数据

答案 0 :(得分：0)
似乎你的条件错了
尝试
if (request.getParameter("today").equals(date_to_string))
而不是
if (request.getParameter("today").equals("dateNow"))
答案 1 :(得分：0)
使用AJAX从Javascript调用此方法。您可以使用JSON对象以方便使用。 Ex ajax： $ .getJSON（URL，功能（数据）{
}
您将在{[your string]}等数据中获取字符串。
为了比较日期，您可以使用dateNow.after（anyDate）和dateNow.before（anyDate）和dateNow.equals（anyDate）以方便使用。
答案 2 :(得分：0)
查看代码：
Date dateNow = new Date();
...
if (request.getParameter("today").equals("dateNow"))
我想你的意图是检查：
if (request.getParameter("today").equals(date_to_string))
另外，别忘了修理：
if(request.getParameter("today").equals("dateNow-2"))
答案 3 :(得分：0)
尝试理解以下代码，希望您能得到答案......
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class Demo {
public static void main(String[] args) {
Calendar cal = Calendar.getInstance();
Date today=cal.getTime();
SimpleDateFormat formatDateJava = new SimpleDateFormat("MM/dd/yyyy");
String today_string = formatDateJava.format(today);
System.out.println("The current date is : " + today_string);
cal.add(Calendar.DATE, -1);
Date today_minus_1=cal.getTime();
String today_minus_1_string=formatDateJava.format(today_minus_1);
System.out.println(today_minus_1_string);
}
}
