B day countdowns12/29/2022 ![]() ![]() You can rather useĭate.now() which returns the total milliseconds from Jan 1, 1970. The main problem, you were comparing date strings to 0. Keep it within the function so it only runs again if the countdown must go on. The setInterval function must always execute only if "not EXPIRED!". Always incude scripts at the last or use window.onload = (function() ()). The script loads before the elements load. If (!end) end = parseDateDMY(document.getElementById("myDate").value) Get the value of countdown and parse it, see parsing function Timer = setInterval(showRemaining, 1000) If click came from the button or timer isn't set, restart the timer Since listener is attached by addEventListener, event will only be passed Also need a global timer reference so it can be cancelled when required document.getElementById("myDate").value = end Don't set the value for end until the button is pressed. Both can be fixed, but out of scope here. Also, invalid date input should be dealt with. Note that setInterval will drift as it doesn't run at exactly every second, so every now and then it will skip two seconds. So, don't start the timer until the button is pressed (or some other event after the page is loaded), stop any timer that is currently running and reset end at the same time. You can test for support and handle cases where it isn't, but it's all a bit much for this exercise. Fixing that isn't hard, but I'm not going to fix it here.ĭon't use input type Date, support is patchy. The calculation is flawed as there aren't exactly 30 days in every month, nor 24 hours in every day if the host observes daylight saving. The button will allow multiple instance of setInterval to be running, so you'll get some pretty confusing results since they're all trying to set the value of countdown Zero (probably initially) or negative (more than 1 millisecond after assigning to end). The script runs before the elements exist in the DOM, so attempts to reference them return null and you'll get errors attempting to set its properties.Įnd is set as the page loads, so it's always in the past in respect to when the function runs, so end - now is either B day countdowns code#There are a number of issues with your code as identified in other answers, I'll paraphrase: Right now it is not not working and any help would be great!
