我做错了什么，我不知道是什么！我正在尝试制作一个函数，在单击时打开弹出窗口或div，我可以在其中显示有关单击的特定产品的相同更多信息。

这是我的代码：

<body onresize="timeline.redraw();" style="background:#F9F8F6">
<div id="mytimeline"  style="background:#fff;min-width:900px;"></div>
<div id="info"></div>
</body>
</html>

你可以使用 jquery 来调用 Google 托管的 jquery：https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js

然后尝试使用此函数：

$( ".timeline-event" ).on( "click", function() {
alert($(this).children('div').text());

});

上面的代码将提醒点击项目的产品名称。将警报替换为您需要的任何操作:)
