Question

Ich möchte einen jQuery Countdown-Timer erstellen, ich habe versucht, wie der folgende Code, aber es funktioniert nicht.Was mache ich?

DEMO:https://jsfiddle.net/tbosn210/

var interval = setInterval(function() { 
 
    
 
    var timer2 = $("5:01"); 
 
    var timer = timer2.split(':'); 
 
    //by parsing integer, I avoid all extra string processing 
 
    var minutes = parseInt(timer[0],10); 
 
    var seconds = parseInt(timer[1],10); 
 
    --seconds; 
 
    minutes = (seconds < 0) ? --minutes : minutes; 
 
    if (minutes < 0) clearInterval(interval); 
 
    seconds = (seconds < 0) ? 59 : seconds; 
 
    seconds = (seconds < 10) ? '0' + seconds : seconds; 
 
    //minutes = (minutes < 10) ? minutes : minutes; 
 
    $('.countdown').html(minutes + ':' + seconds); 
 
}, 1000);

Answer 1

aus setInterval Funktion Bewegen Sie timer2 Erklärung, weist neuen Wert der Zeit am Ende der Ausführung Timer2 fortzusetzen.

Arbeits Snippet:

var timer2 = "5:01"; 
 
var interval = setInterval(function() { 
 

 

 
    var timer = timer2.split(':'); 
 
    //by parsing integer, I avoid all extra string processing 
 
    var minutes = parseInt(timer[0], 10); 
 
    var seconds = parseInt(timer[1], 10); 
 
    --seconds; 
 
    minutes = (seconds < 0) ? --minutes : minutes; 
 
    if (minutes < 0) clearInterval(interval); 
 
    seconds = (seconds < 0) ? 59 : seconds; 
 
    seconds = (seconds < 10) ? '0' + seconds : seconds; 
 
    //minutes = (minutes < 10) ? minutes : minutes; 
 
    $('.countdown').html(minutes + ':' + seconds); 
 
    timer2 = minutes + ':' + seconds; 
 
}, 1000);

Answer 2

var timer2 = $("5:01"); 
    var timer = timer2.split(':'); 

Sie don t müssen jQuery für String wickeln verwenden. also, vor allem zu beheben:

var timer2 = "5:01"; var timer = timer2.split (':');

und die zweite Sie benötigen 05.01 die Startvariable raus, weil jeder Ihr Intervall Iteration den Startwert auf 5.01 zurückgesetzt

Answer 3

var timer2 = "5:01"; 
 
var interval = setInterval(function() { 
 

 

 
    var timer = timer2.split(':'); 
 
    //by parsing integer, I avoid all extra string processing 
 
    var minutes = parseInt(timer[0], 10); 
 
    var seconds = parseInt(timer[1], 10); 
 
    --seconds; 
 
    minutes = (seconds < 0) ? --minutes : minutes; 
 
    seconds = (seconds < 0) ? 59 : seconds; 
 
    seconds = (seconds < 10) ? '0' + seconds : seconds; 
 
    //minutes = (minutes < 10) ? minutes : minutes; 
 
    $('.countdown').html(minutes + ':' + seconds); 
 
    if (minutes < 0) clearInterval(interval); 
 
    //check if both minutes and seconds are 0 
 
    if ((seconds <= 0) && (minutes <= 0)) clearInterval(interval); 
 
    timer2 = minutes + ':' + seconds; 
 
}, 1000);

<div class="countdown"></div>

Die obige Snippet wird ein Countdown zur Verfügung stellen bis 0:00 Uhr Die clearInterval Funktion sollte am Ende aufgerufen werden, indem überprüft wird, ob Minuten und Sekunden beide 0 als ihren Wert enthalten oder nicht.

    var seconds = parseInt(timer[1], 10); 
 
    --seconds; 
 
    minutes = (seconds < 0) ? --minutes : minutes; 
 
    if (minutes < 0) clearInterval(interval); 
 
    seconds = (seconds < 0) ? 59 : seconds; 
 
    seconds = (seconds < 10) ? '0' + seconds : seconds; 
 
    //minutes = (minutes < 10) ? minutes : minutes; 
 
    $('.countdown').html(minutes + ':' + seconds); 
 
    timer2 = minutes + ':' + seconds; 
 
}, 1000);
