Javascript:: Is audio.pause reset audio.currentTime value to 0?

问题

My code is working perfectly except the fact that instead of pause the track it's going back to the beginning of the track.

Here is my code:

var audio=new Audio();

var hezi=document.querySelector('#player>.button.hand');
var gangina=("textContent" in document)?"textContent":"innerText";

hezi.addEventListener
(
    'click',
    function()
    {

        if(audio.paused)
        {
            audio.src="Nadav Guedj - Golden Boy (Eurovision 2015 - Israel - Karaoke).mp3";
            hezi.innerHTML="&#9658;";
            audio.play();
        }
        else
        {
            hezi.innerHTML="||";
            audio.pause();
        }

    }
);

I'm going to assume that to solve this issue I need to store the audio.currentTime value of that track with window.setInterval and use the last audio.currentTime value to play the track from the last point where it stopped but I was wonder if there is continent way to make the pause/play button function properly (not to mention the fact that if I would store that last value via window.setInterval it wouldn't be 100% accurate since I'm relying on the interval value and not the exact specific point where the user paused the track).

回答1:

it is going back to the beginning because of this line,

        audio.src="Nadav Guedj - Golden Boy (Eurovision 2015 - Israel - Karaoke).mp3";

remove that, then audio.play would continue from where you paused. fiddle demo

回答2:

Try to store in a variable the currentTime on the click event handler when user pauses the player.

This way you'll have the exact moment where the music was stopped, just store it on a variable out of object's scope.
