Question

使用HTML5和jQuery，我想实现JPlayer（来自www.jplayer.org）。

不幸的是，我不能按照我想要的方式工作。最后，我的问题似乎是样式表＆＃34;包含＆＃34;的问题。出于某些原因，我不明白，使用＆＃34; jQuery appendTo head＆＃34;时，样式表无法正常工作。而不是＆＃34; html链接＆＃34;。该文件是定义包含的，但在触发javascript操作时，GUI会搞砸。

我附上了两个可以在任何地方用于测试的例子。我对唯一不同的行做了评论。

这是第一个文件。此示例按预期工作：

<!DOCTYPE html>

<head>
    <meta charset="utf-8" />
    <title>Test with link rel</title>

    <!-- ONLY DIFFERENCE IS THIS LINE -->
    <link rel="stylesheet" type="text/css" href="http://www.jplayer.org/latest/skin/blue.monday/jplayer.blue.monday.css" />
    <!-- END -->

</head>

样式表正在处理第二个文件，但只要您点击播放器上的内容，GUI就会搞砸。这是为什么？我可以对提供的jPlayer样式表进行一些更改，以使其适用于我的第二个示例吗？

Answer 1

这应该可以解决您的问题，一旦加载CSS文件就调用插件：

$('<link>', {
    rel: 'stylesheet',
    type: 'text/css',
    href: 'http://www.jplayer.org/latest/skin/blue.monday/jplayer.blue.monday.css'
}).one('load', function () {
    $("#jquery_jplayer_1").jPlayer({
        ready: function (event) {
            $(this).jPlayer("setMedia", {
                m4a: "http://www.jplayer.org/audio/m4a/TSP-01-Cro_magnon_man.m4a"
            });
        },
        supplied: "m4a",
        wmode: "window",
        smoothPlayBar: true,
        keyEnabled: true
    });
}).appendTo('head');

虽然，在大多数情况下这可能就足够了：

$('<link>', { rel: 'stylesheet', type: 'text/css', href: 'http://www.jplayer.org/latest/skin/blue.monday/jplayer.blue.monday.css' }).appendTo('head');
$("#jquery_jplayer_1").jPlayer({ready: function (event) {$(this).jPlayer("setMedia", {m4a:"http://www.jplayer.org/audio/m4a/TSP-01-Cro_magnon_man.m4a"});},supplied: "m4a",wmode: "window",smoothPlayBar: true,keyEnabled: true});

包括样式表在内给出与javascript附加不同的结果
