我是网络编程的绝对菜鸟,我似乎无法在下面找到爆米花样本。我正在尝试从工作示例中实现它:http://jsfiddle.net/thisgeek/At3xg/
有人可以发现我做错了吗?请注意,下面的代码中的音频没有及时突出显示音频,但它们在jfiddle示例中有效。
谢谢!

var wordTimes = {

"w2": { start: 1.9, end: 2.5 },

$.each(wordTimes, function(id, time) {
pop.footnote({
start: time.start,

audio[0].currentTime = parseFloat($(this).data('start'), 10);

将所有自己的JavaScript代码包装在
中$(document).ready(function() { /* your code here */ });
或在</body>
标记之后移动它,因此等到HTML主体加载后才会运行。
当您在左上角设置onLoad
下拉列表时,jsFiddle会自动执行此操作。
