JS example code for page real-time update time

Copy the code code as follows:

function startTime() {

var today = new Date(); //Define date object

var yyyy = today.getFullYear(); //Return the year through the getFullYear() method of the date object

var MM = today.getMonth() + 1; //Return the year through the getMonth() method of the date object

var dd = today.getDate(); //Return the year through the getDate() method of the date object

var hh = today.getHours(); //Return the hour through the getHours method of the date object

var mm = today.getMinutes(); //Return minutes through the getMinutes method of the date object

var ss = today.getSeconds(); //Return seconds through the getSeconds method of the date object

// If the value of the minute or hour is less than 10, add 0 in front of its value. For example, if the time is 3:20:9, it will display 15:20:09

MM = checkTime(MM);

dd = checkTime(dd);

mm = checkTime(mm);

ss = checkTime(ss);

var day; //Used to save the day of the week (the getDay() method gets the day of the week number)

if (today.getDay() == 0) day = "Sunday"

if (today.getDay() == 1) day = "Monday"

if (today.getDay() == 2) day = "Tuesday"

if (today.getDay() == 3) day = "Wednesday"

if (today.getDay() == 4) day = "Thursday"

if (today.getDay() == 5) day = "Friday"

if (today.getDay() == 6) day = "Saturday"

document.getElementById('nowDateTimeSpan').innerHTML = yyyy + "-" + MM + "-" + dd + " " + hh + ":" + mm + ":" + ss + " " + day;

setTimeout('startTime()', 1000); //Reload the startTime() method every second

}

function checkTime(i) {

if (i < 10) {

i = "0" + i;

}

return i;

}
