javascript - jQuery - jquery-3.4.1.min.js:2 Uncaught ReferenceError: filter is not defined

问题描述

我使用jsGrid本地json文件作为数据源。我在端口 4000 上设置了一个本地json-server运行来提供动态数据。当我点击时http://localhost:4000/networks，我看到 json 就好了。我还设置了一个带有npm'http-server包的本地 http 服务器来访问我的网页。但是，当我尝试点击时http://localhost:8080，我得到一个空白页。在开发控制台中，我看到了这个错误：jquery-3.4.1.min.js:2 Uncaught ReferenceError: filter is not defined. 我对有点陌生jQuery，不知道为什么会发生这个错误。下面是我的目录结构、我的html文件、js、示例 json 和错误。
