播放音频文件时用键盘播放时向前和向后搜索十秒
Playing audio file to seek by ten seconds forward and backward while playing with keyboard
我可以通过键盘播放暂停和停止音频文件,但是当我来回搜索时,我使用左右方向键,并且正在搜索15秒。相反,我需要做 5 或 10 秒。下面是我使用的java脚本
<script>
var audio = $("audio")[0];
$(document).keydown(function (e) {
var unicode = e.charCode ? e.charCode : e.keyCode;
console.log(unicode);
// right arrow
if (unicode == 39) {
audio.currentTime += 5;
// back arrow
} else if (unicode == 37) {
audio.currentTime -= 5;
// spacebar
} else if (unicode == 32) {
if (audio.paused) {
audio.play();
}
else {
audio.pause()
}
}
});
</script>
I am seeking back and forth, I am using left and right arrow keys, and
it is being seeking 15 sec. I need to do it for 5 or 10
您可以使用 <audio>
元素的 HTMLMediaElement.currentTime
来设置音频开始播放的位置; +=
或 -=
运算符将 audio.currentTime
递增或递减 n 秒,例如 5
或 10seconds; check [
HTMLMediaElement.paused][2] to toggle calling
audio.play()or
audio.pause()`

<audio controls autoplay src="https://upload.wikimedia.org/wikipedia/commons/6/6e/Micronesia_National_Anthem.ogg"></audio>
<script>
var audio = $("audio")[0];
$(document).keydown(function(e) {
var unicode = e.charCode ? e.charCode : e.keyCode;
console.log(unicode);
// right arrow
if (unicode == 39) {
audio.currentTime += 5;
// back arrow
} else if (unicode == 37) {
audio.currentTime -= 5;
// spacebar
} else if (unicode == 32) {
if (audio.paused) {
audio.play();
}
else {
audio.pause()
}
}
});
