在Angular 8中添加外部库

Question

I want to use some external jQuery libraries in my Angular project.

I added these libraries inside index.html file, but they are not working. I also added my .js files in angular.json , but the problem still exists. I add libraries like this:

 <!-- CUSTOM JS --> <script src="assets/js/jquery.app.js"></script> 

Actually the code in this js file is not reachable. It seems Angular does not understand it to go and run that specific function in this file.

I expect a menu item shows its sub menus but the jQuery code does not work in Angular.

As you use Angular, you probably also use the angular/cli. In that case, just add your file in the angular.json file like :

  "scripts": [
    "../node_modules/jquery/dist/jquery.js"
  ],

This will let angular import your external lib in the end bundle.

You will find more informations in the official documentation : https://github.com/angular/angular-cli/wiki/stories-global-scripts
