Two ways to display the current time in a JSP page simple instance _jsp programming

The JSP page implementation shows the current date time, we can use two ways to achieve:

1. By adding Java code implementations to the JSP page, the main code looks like this

Java.text.SimpleDateFormat SimpleDateFormat = new Java.text.SimpleDateFormat ( 
   "Yyyy-mm-dd HH:mm:ss"); 
  Java.util.Date currenttime = new Java.util.Date (); 
  String time = Simpledateformat.format (currenttime). toString ();  Put it in the head of the page} 

Current DateTime:<%=time%> This displays the formatted date time, and can be formatted differently in SimpleDateFormat according to our needs

2. Through JS implementation.

JS code is as follows: Clock.js

function Showtime () {var today; Var hour; var second; var minute; var year; var month; var date; var strdate; 
Today=new Date (); 
var n_day = Today.getday (); 
Switch (n_day) {case 0:{strdate = "Sunday"}break; 
Case 1:{strdate = "Monday"}break; 
Case 2:{strdate = "Tuesday"}break; 
Case 3:{strdate = "Wednesday"}break; 
Case 4:{strdate = "Thursday"}break; 
Case 5:{strdate = "Friday"}break; 
Case 6:{strdate = "Saturday"}break; 
Case 7:{strdate = "Sunday"}break; 
Year = Today.getyear (); 
month = Today.getmonth () +1; 
Date = Today.getdate (); 
hour = Today.gethours (); 
Minute =today.getminutes (); 
Second = Today.getseconds (); 
if (month<10) month= "0" +month; 
if (date<10) date= "0" +date; 
if (hour<10) hour= "0" +hour; 
if (minute<10) minute= "0" +minute; 
if (second<10) second= "0" +second;  document.getElementById (' clock '). InnerHTML = year + "years" + month + "Month" + Date + "Day" + strdate + "" + Hour + ":" + Minute + 
":" + second; 
SetTimeout ("Showtime ();", 1000); }

Then we introduce this JS in the JSP page,

The method Showtime () in the call can get the current time

The above is a small series for everyone to bring the JSP page two ways to show the current time of the simple example of all the content, I hope that we support cloud-Habitat Community ~
