jQuery 问题 - 未捕获的 TypeError : Cannot read property 'browser' of undefined

Question

我正在尝试向网站添加 slider 。

当我在本地测试时，它在标准 html 文件中工作正常，但是当我尝试将其传输到 WordPress 网站时，我不断收到此错误:

Uncaught TypeError: Cannot read property 'browser' of undefined

它指向问题代码中的第 11 行

isIE = $.browser.msie,

我不确定发生了什么，因为它在基本文件中运行，而不是在 WordPress Live 站点中运行。

这是 slider 的 jquery 文件 - 我确信它很简单，但我只是没有弄清楚。

谢谢瑞安

默认情况下，我认为 WordPress 将 jQuery 置于“无冲突”模式，因此使用 $ 作为 jQuery 的快捷方式将不起作用。我猜这是你的问题，因为错误表明 $ 未定义。

来自 WordPress 文档:

In order to use the default jQuery shortcut of $, you can use the following wrapper around your code:

jQuery(document).ready(function($) {
    // $() will work as an alias for jQuery() inside of this function
});

或者，您可以在代码中使用 $ 的任何地方使用 jQuery:

isIE = jQuery.browser.msie

您可以在Wordpress docs中阅读更多相关信息。 .
