Question

我有以下代码，应该做我需要的：

function fromSeconds(seconds, showHours = false) {
    if(showHours) {
        var hours = Math.floor(seconds / 3600),
            seconds = seconds - hours * 3600;
    }
    var minutes = (Math.floor(seconds/60) < 10) ? 
        "0" + Math.floor(seconds/60) : Math.floor(seconds/60);
    var seconds = (seconds % 60 > 9) ? seconds % 60 : "0" + seconds % 60;

    if(showHours) {
        var timestring = hours + ":" + minutes + ":" + seconds;
    } else {
        var timestring = minutes + ":" + seconds;
    }
    return timestring;
}

问题在于我也有：

var video = $('#home_explainer_placeholder');
video.bind("timeupdate", function() {
    $('#currentTime').html(video[0].currentTime.toFixed(2));
    $('#remTime').html((video[0].duration - video[0].currentTime).toFixed(2));
    $('#totalTime').html(video[0].duration.toFixed(2));
});

而且我不知道如何应用第一个代码，以便例如currentTime显示如下：minutes:seconds。

请帮忙吗？

Answer 1

您可以将video[0].currentTime之类的值传递给函数fromSeconds，该函数将返回格式化字符串

var video = $('#home_explainer_placeholder');
video.bind("timeupdate", function () {
    $('#currentTime').html(fromSeconds(video[0].currentTime));
    $('#remTime').html(fromSeconds(video[0].duration - video[0].currentTime));
    $('#totalTime').html(fromSeconds(video[0].duration));
});

Answer 2

通过小固定，您可以将其保留为：

Answer 3

 $('#currentTime').html(function(){
     var time=video[0].currentTime.toFixed(2);
     //some conversion needed in-order to convert to required format
     fromSeconds(time,false)//returns time 
 });

Answer 4

假设- (UIView *)mapView:(GMSMapView *)mapView markerInfoWindow:(GMSMarker *)marker { NSLog(@"the post title is :%@ %@",marker.userData,marker.title); CustomInfoWindow *view = [[[NSBundle mainBundle] loadNibNamed:@"CustomInfoWindow" owner:self options:nil] objectAtIndex:0]; // Your Created Custom View XIB. UILabel *theLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 50,150, 50)];// Create a Custom Label and add it on the custom view. theLabel.text = marker.title; // marker.title is the title of pin. [view addSubview:theLabel]; return view; }是以秒为单位的时间，您需要将值传递给您的函数。

currentTime会返回您需要的文字，因此fromSeconds会根据需要返回fromSeconds(mytimevalue)：

mm:ss

另一种选择是使用JavaScript的video.bind("timeupdate", function() { $('#currentTime').html( fromSeconds(video[0].currentTime) ); $('#remTime').html( fromSeconds(video[0].duration - video[0].currentTime) ); $('#totalTime').html( fromSeconds(video[0].duration) ); });对象，它以毫秒为值： Date()

然后，您可以使用var currentTime = new Date(video[0].currentTime * 1000);和Date.getMinutes()来查找您的值。
