好吧，我有以下 HTML 代码，该代码适用于应该从 API 检索天气数据的应用程序。

现在，我仍在设置界面。在代码的末尾，我有一些 Javascript，当用户按下 Enter 键时，它会提醒文本框中的最后两个字符。这工作正常。然而，我还有一些 jQuery 之后应该淡出 .这部分不起作用。我收到警报，但没有消失。这是为什么？

谢谢。
最佳答案
您已放置 div id-"all" 而不是 div id="all"，因此 jQuery 无法定位该 div
关于javascript - jQuery 淡出不起作用？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21356771/
