javascript - 使用 Javascript/Jquery 停止 html 声音

Question

我正在尝试启动和停止声音，当单击一个按钮时，哪个类随 .toggleClass() 发生变化。当我单击按钮时声音应该开始，当我再次单击它或单击播放另一个声音的另一个按钮时停止。但是，当我再次单击按钮时，声音并没有停止，而是从头开始播放。我尝试了几种方法，但似乎无法使用我当前的代码。对我来说重要的是，当播放另一种声音时，声音也会停止。那已经有效了。我希望你能明白我的意思，我不知道如何更好地解释它。 (抱歉我的英语不好，如果您有任何问题，请联系我)。如果有人能帮助我，我会很高兴。

这是我停止声音的尝试:

$(document).ready(function () {
    $(".fa-volume-up").click(function () {
        $('audio').each(function () {
            this.pause();
            this.currentTime = 0;
        });
    });
});

这是我的全部代码:

//Icon color change
$(document).ready(function() {
  $(".fa-volume-off,.fa-volume-up").click(function() {
    $(".fa-volume-off").toggleClass("fa-volume-up");
  });
});

//Sound
var currentsound;

function EvalSound(soundobj) {
  if (currentsound) {
    currentsound.pause();
  }
  var thissound = document.getElementById(soundobj);
  thissound.currentTime = 0;
  thissound.play();
  currentsound = thissound;
}

//Stop sound on click 
$(document).ready(function() {
  $(".fa-volume-up").click(function() {
    $('audio').each(function() {
      this.pause();
      this.currentTime = 0;
    });
  });
});

Answer 1

我刚刚想出了如何在不为每个声音元素添加新类和 ID 的情况下做到这一点。

这是有效的 js 代码:

$(document).ready(function () {
//change icon and icon color
$(".fa-volume-off,.fa-volume-up").click(function () {
    $(this).toggleClass("fa-volume-up");
    $('.fa-volume-up').not($(this)).removeClass('fa-volume-up');
    //stop audio on second button click
    $(".speaker").click(function () {
        if (!$(this).hasClass("fa-volume-up")) {
            $(".audio").trigger("pause");
        }
    });
});});

   //stop sound and start different sound
var currentsound;
function EvalSound(soundobj) {
    if (currentsound) {
        currentsound.pause();
    }
    var thissound = document.getElementById(soundobj);
    thissound.currentTime = 0;
    thissound.play();
    currentsound = thissound;
};

和演示:

$(document).ready(function() {
  //change icon and icon color
  $(".fa-volume-off,.fa-volume-up").click(function() {
    $(this).toggleClass("fa-volume-up");
    $('.fa-volume-up').not($(this)).removeClass('fa-volume-up');
    //stop audio on second button click
    $(".speaker").click(function() {
      if (!$(this).hasClass("fa-volume-up")) {
        $(".audio").trigger("pause");
      }
    });
  });
});

//stop sound and start second sound
var currentsound;

function EvalSound(soundobj) {
  if (currentsound) {
    currentsound.pause();
  }
  var thissound = document.getElementById(soundobj);
  thissound.currentTime = 0;
  thissound.play();
  currentsound = thissound;
};
