當前時間秒

Question

我有奇怪的問題..我有一個功能，以顯示與秒計數的時間，但我發送特定的時間（小時和分鐘）作爲參數時，第二個到達59的計數沒有增加分鐘，我不知道如果與時間相同問題的時候分鐘就會59分鐘

function updateClock(current_hours,current_minutes) { 
var currentTime = new Date (); 

var currentHours = current_hours; 
var currentMinutes = current_minutes; 
var currentSeconds = currentTime.getSeconds (); 

// Pad the minutes and seconds with leading zeros, if required 
currentMinutes = (currentMinutes < 10 ? "0" : "") + currentMinutes; 
currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds; 

// Choose either "AM" or "PM" as appropriate 
var timeOfDay = (currentHours < 12) ? "AM" : "PM"; 

// Convert the hours component to 12-hour format if needed 
currentHours = (currentHours > 12) ? currentHours - 12 : currentHours; 

// Convert an hours component of "0" to "12" 
currentHours = (currentHours == 0) ? 12 : currentHours; 

// Compose the string for display 
var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay; 

// Big font time 
$('.big_time').html("<span></span>" + currentTimeString); 

// Time in red triangle in the track bar 
$('.time').html(currentTimeString); 
} 

我呼籲在裏面的文件準備像其他文件這一功能..我這裏發出從API檢索的數據（小時和分鐘）

current_hours = data.current_hours; 
current_minutes = data.current_minutes; 

setInterval(function(){updateClock(current_hours,current_minutes)},1000); 

Answer 1

使用這個代替

function updateClock () 
    { 
    var currentTime = new Date (); 
    var currentHours = currentTime.getHours (); 
    var currentMinutes = currentTime.getMinutes (); 
    var currentSeconds = currentTime.getSeconds (); 

    // Pad the minutes and seconds with leading zeros, if required 
    currentMinutes = (currentMinutes < 10 ? "0" : "") + currentMinutes; 
    currentSeconds = (currentSeconds < 10 ? "0" : "") + currentSeconds; 

    // Choose either "AM" or "PM" as appropriate 
    var timeOfDay = (currentHours < 12) ? "AM" : "PM"; 

    // Convert the hours component to 12-hour format if needed 
    currentHours = (currentHours > 12) ? currentHours - 12 : currentHours; 

    // Convert an hours component of "0" to "12" 
    currentHours = (currentHours == 0) ? 12 : currentHours; 

    // Compose the string for display 
    var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay; 
    
    
    $("#clock").html(currentTimeString); 
        
 } 

$(document).ready(function() 
{ 
   setInterval('updateClock()', 1000); 
});

請檢查循環是否經過60計數或結束於59本身，例如 （i = 1，i < = 60：i ++）它會到達59並結束，檢查開始和結束值。
