Uncaught TypeError: $(...).velocity is not a function

Question

我有以下代码：

var $ = require('jquery');
var velocity = require('velocity-animate');

module.exports = function () {

    function togglePanel () {

        $('.trip-assist-search-panel__container').velocity({
            height: '0px'
        },{
            duration: 400
        });

    }

    return {
        togglePanel: togglePanel
    };

}();

当 togglePanel() 被触发时，抛出以下错误：

Uncaught TypeError: $(...).velocity is not a function

这通常可以通过确保在需要它的库之前加载 JQuery 来解决。但是，我是..

var $ = require('jquery'); // first
var velocity = require('velocity-animate'); // second

那么..是什么给了？

来自the documentation：

Module Loader: Browserify
If you're using Velocity with jQuery, you must require jQuery before Velocity, and you must assign jQuery globally on the window object:
window.jQuery = window.$ = require("path/to/jquery-x.x.x.js");
require("path/to/velocity.js");
// Optional: If you're using the UI pack, require it after Velocity. (You don't need to assign it to a variable.)
require("path/to/velocity.ui.js");
/* Your app code here. */
$("body").velocity({ opacity: 0.5 });

您只将 jQuery 分配给 local $ 变量。
