我如何停止使用Jquery的所有音频播放

更新时间:2023-10-29 12:43:46

我要重写代码,但是我最后通过将动画加载到当您点击下一个按钮而不是仅更新一个div时,您的整体。



这是一个解决方法,但至少现在工作。



感谢奥马尔谁帮助了很多这个问题。


I'm updating a div in a page using jquery mobile in order to play some animations.

The animations also play sound through use of document.createElement('audio');

My problem is, when I update the page to another animation, the old sound keeps playing.

Sorry, this is my first question and if it seems like im not phrasing it properly I apologise.

Here is my code..

Here is the code of the animation to be loaded into the #animation div

<!DOCTYPE HTML>
<html>
  <head>
    <style>
      body {
        margin: 0px;
        padding: 0px;
      }
    </style>
  </head>
<body>
    <div id="container"></div>

    var stage = new Kinetic.Stage({
        container: 'container',
        width: 578,
        height: 400
    });
    var babyLayer = new Kinetic.Layer();
    var backLayer = new Kinetic.Layer();


    var imageObj = new Image();
    var backObj = new Image();
    imageObj.onload = function() {
    var baby = new Kinetic.Image({
      x: stage.getWidth() / 2 -100 ,
      y: stage.getHeight() / 2 -100,
      image: imageObj,
      width: 200,
      height: 200,
      opacity: 0.0
    });

    var background = new Kinetic.Image({
      x: 0,
      y: 0,
      image: backObj,
      width: 578,
      height: 400,

    });

    // add the shape to the layer
    babyLayer.add(baby);
    backLayer.add(background);

    // add the layer to the stage
    stage.add(babyLayer);
    stage.add(backLayer);
    babyLayer.moveToTop();
    babyLayer.draw();

</script>

Here is the main page code. It gets the filename of the animation page to be loaded into #animation from an array when you click the next button.

<div id="nav" data-role="content" style="width: 600px; margin: 0 auto; text-align: center; position: relative; top:450px">
    <a href="#animation" data-role="button" data-inline="true" id ="back">Back</a>
    <a href="#animation" data-role="button" data-inline="true" data-theme="b" id="next">Next</a>
    <script>
        var count=0;
        var link_array = ['baby', 'bed', 'book', 'cat', 'chair', 'daddy', 'dog', 'mummy', 'shoe', 'teddy'];
        $("#next").click(function(e) {
            if(count!==9)
            { 
                $('audio').stop();
                count+=1;
            }
            $('#animation1wl').load('../Animations/' + link_array[count] + '.html');
            $('#animation1wl').trigger('create');
        }); 
        $("#back").click(function(e) {
            if(count !==0)
            {
                count-=1;
            }
            $('#animation1wl').load('../Animations/' + link_array[count] + '.html');
            $('#animation1wl').trigger('create');
        }); 
    </script>
</div>

<div id="animation" data-role="content" style="width: 600px; margin: 0 auto; text-align: left">Problem Loading Resource LNW</div>

When I click the forward or back buttons, I want the audio from the previous animation loaded into #animation to stop playing..

Here is the code rendered inside #animation

<div id="animation1wl" data-role="content" style="width: 600px; margin: 0 auto; text-align: left" class="ui-content" role="main">

Any help would be great..

Thanks very much.

Ihad to rewrite the code but, I got this working in the end by loading the animation in its entirety when you click on the next button rather than just updating a single div.

It's a workaround but at least its working now.

Thanks to Omar who helped a lot with this problem.
