Question

I want see on display CurrentTime minute and second video.

var id = $('#main_video_player');

alert(id.get(0).currentTime); //worked i see '12.324543356'

var minnow=id.get(0).currentTime.split('.')[0];   
alert(minnow); //not worked

var secnow=id.get(0).currentTime.split('.')[1].substr('0','1');   
alert(secnow); //not worked

Thanks all for help=)

Right code for show seconds:

alert(time.toString().split('.')[0]);

Code down for show correct time in hours, minute an second:

var id = $('#video');

timenow=id.get(0).currentTime;

if (parseInt(timenow)/60>=1) {
        var h = Math.floor(timenow / 3600);
        timenow = timenow - h * 3600;               
        var m = Math.floor(timenow / 60);
        var s = Math.floor(timenow % 60);
        if(h.toString().length<2){h='0'+h;}
        if(m.toString().length<2){m='0'+m;}
        if(s.toString().length<2){s='0'+s;}
        alert(h+' : '+m+' : '+s);          
    } else {
        var m = Math.floor(timenow / 60);
        var s = Math.floor(timenow % 60);
        if(m.toString().length<2){m='0'+m;}
        if(s.toString().length<2){s='0'+s;}
        alert(m+' : '+s);
}

You need to convert the currentTime to a String to perform .split() and .substr() on it, e.g.

var time = id.get(0).currentTime;
var minutes = time.toString().split('.')[0];   
var seconds = time.toString().split('.')[1].substr('0','1'); 

To convert them back to a float (Number) for use with numerical functions do like so:

minutes = parseFloat(minutes);

See http://jsfiddle.net/NpgD5/23/ for a working example (click on the video to get the time).

EDIT: currentTime returns the time in seconds so your minnow variable is actually seconds and secnow are milliseconds, a better way of getting minutes and seconds from currentTime is:

var time = id.get(0).currentTime;
var minutes = Math.floor(time / 60);   
var seconds = Math.floor(time);
