Countdown in Javascript?
Put the dates in an array. Be careful, in Javascript the months are zero-based so ranging from 0 to 11. Iterate the array and when the date is bigger then today display the days in between: var calcPayDate = function () { var payDates = ; payDates.
Push(new Date(2011, 0, 1)); payDates. Push(new Date(2011, 1, 15)); payDates. Push(new Date(2011, 2, 12)); payDates.
Push(new Date(2011, 3, 20)); var today = new Date(); for (var I = 0; I today) { document. GetElementById('countdownDiv'). InnerHTML = calcDays(payDatesi, today); break; } } } var calcDays = function(date1, date2) { // The number of milliseconds in one day var ONE_DAY = 1000 * 60 * 60 * 24 // Convert both dates to milliseconds var date1_ms = date1.getTime() var date2_ms = date2.getTime() // Calculate the difference in milliseconds var difference_ms = Math.
Abs(date1_ms - date2_ms) // Convert back to days and return return Math. Round(difference_ms / ONE_DAY) } The calcDays function is an function found on this site The days are put in a div which is called 'countdownDiv.

Am I doing this wrong: jsfiddle. Net/fWYrM? – dannymcc Feb 28 at 12:04 @dannymcc: You just have to call the actual function: jsfiddle.Net/fWYrM/1 – pimvdb Feb 28 at 12:06 Like @pimvdb said.
Call the function in the onload of the body. Or use a framework like jQuery to bind it to the onload event. – TurBas Feb 28 at 12:32.
Search the web for "JavaScript tutorial". Meanwhile, here's some code to get you started: var dates = new Date(2011, 0, 1), // note that format is year, month-1, day new Date(2011, 1, 15), // don't ask me why new Date(2011, 2, 12), new Date(2011, 3, 20) ; var now = new Date(); for (var I in dates) { // this is a foreach loop if (now Ceil((datesi - now) / 86400000)); break; } }.
1 In your code, variable I is not initialized and you use for-in loop to iterate through array. Both are considered harmful. You should edit your code.
– duri Feb 28 at 11:51 @duri "i is not initialised" - but it's given a value first time it's used! "you use for-in loop to iterate through array" - what's wrong with that? – Stewart Feb 28 at 19:12 It doesn't matter whether it's given a value or not.
Using var prevents the variable from leaking to the global scope. + see stackoverflow. Com/questions/500504/… – duri Feb 28 at 20:10 @duri You didn't say anything about using var.
You talked about initialising the variable - which in my vocabulary, means giving it a starting value. But I agree that using var is a good idea - I had just forgotten it on this occasion. And I'll have to investigate the for..in debate more closely.... – Stewart Mar 1 at 0:56 To initialise a variable means to use var keyword.
Sorry for the confusion. – duri Mar 1 at 7:52.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
