以秒为单位的当前时间


current time with seconds

我有一个奇怪的问题。我有一个功能来显示时间与秒计数器,但我发送了特定的时间(小时和分钟)作为参数时,秒的计数达到59没有分钟增加,我不确定如果相同的问题与小时时,分钟将是59分钟

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);
}

我在文档中的另一个文件中调用这个函数。我在这里发送了从API检索到的数据(小时和分钟)

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

用这个代替

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);
});

从这里得到这个代码

请检查循环是否经过60次计数或在59次计数结束对于(i=1,i<=60:i++),它将转到59并结束,检查起始值和结束值
