Javascript to display the current date and time
提问by john Gu
I have the following test Script to display the current date & time :-
我有以下测试脚本来显示当前日期和时间：-
document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {
var date = new Date();
var hours = date.getHours();
var days = date.getDay();
var minutes = date.getMinutes();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0'+minutes : minutes;
var strTime = date + ' ' + hours + ':' + minutes + ' ' + ampm;
return strTime;
}
which will display the following :-
这将显示以下内容：-
Fri Aug 30 2013 16:36:10 GMT+0100 (GMT Standard Time) 4:36 pm
but i need to modify this to display only:-

Try this:
试试这个：
var d = new Date(),
minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
ampm = d.getHours() >= 12 ? 'pm' : 'am',
months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;

Demo using Console.Log
演示使用 Console.Log
// get a new date (locale machine date time)
var date = new Date();
// get the date as a string
var n = date.toDateString();
// get the time as a string
var time = date.toLocaleTimeString();
// log the date in the browser console
console.log('date:', n);
// log the time in the browser console
console.log('time:',time);Demo using a DIV
演示使用 DIV
// get a new date (locale machine date time)
var date = new Date();
// get the date as a string
var n = date.toDateString();
// get the time as a string
var time = date.toLocaleTimeString();
// find the html element with the id of time
// set the innerHTML of that element to the date a space the time
document.getElementById('time').innerHTML = n + ' ' + time;<div id='time'></div>Note: these functions aren't fully cross browser supported
注意：这些功能并不完全支持跨浏览器

//Fri Aug 30 2013 4:36 pm
console.log(formatAMPM(new Date()));
//using your function (passing in date)
function formatAMPM(date) {
// gets the hours
var hours = date.getHours();
// gets the day
var days = date.getDay();
// gets the month
var minutes = date.getMinutes();
// gets AM/PM
var ampm = hours >= 12 ? 'pm' : 'am';
// converts hours to 12 hour instead of 24 hour
hours = hours % 12;
// converts 0 (midnight) to 12
hours = hours ? hours : 12; // the hour '0' should be '12'
// converts minutes to have leading 0
minutes = minutes < 10 ? '0'+ minutes : minutes;
// the time string
var time = hours + ':' + minutes + ' ' + ampm;
// gets the match for the date string we want
var match = date.toString().match(/\w{3} \w{3} \d{1,2} \d{4}/);
//the result
return match[0] + ' ' + time;

You can try the below:
您可以尝试以下方法：
function formatAMPM() {
var date = new Date();
var currDate = date.getDate();
var hours = date.getHours();
var dayName = getDayName(date.getDay());
var minutes = date.getMinutes();
var monthName = getMonthName(date.getMonth());
var year = date.getFullYear();
var ampm = hours >= 12 ? 'pm' : 'am';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'
minutes = minutes < 10 ? '0' + minutes : minutes;
var strTime = dayName + ' ' + monthName + ' ' + currDate + ' ' + year + ' ' + hours + ':' + minutes + ' ' + ampm;
alert(strTime);
}
function getMonthName(month) {
var ar = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
return ar[month];
}
function getDayName(day) {
var ar1 = new Array("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat");
return ar1[day];
}

(function(con) {
var oDate = new Date();
var nHrs = oDate.getHours();
var nMin = oDate.getMinutes();
var nDate = oDate.getDate();
var nMnth = oDate.getMonth();
var nYear = oDate.getFullYear();
con.log(nDate + ' - ' + nMnth + ' - ' + nYear);
con.log(nHrs + ' : ' + nMin);
})(console);
This produces an output like:
这会产生如下输出：
30 - 8 - 2013
21 : 30
