Javascript jQuery函数在node.js中的express.js路由上不起作用

我是node.js.My express.js应用程序结构中的新手：

| my-application
| -- app.js
| -- node_modules
| -- public
| -- models
     | -- users.js
| -- routes
     | -- index.js
| -- views
     | -- index.ejs

我尝试使用$.inArray（）函数。我安装了这个软件包

routes/index.js

var express  = require('express');
var $        = require('jquery');
var router   = express.Router();

router.get('/', function(req, res, next) {
  var arr = [ 'a','b','c' ];
  $.inArray('a',arr);

  res.render('index',{
      title:'home'
  });
});

module.exports = router;

它给了我以下错误：

undefined is not a function
TypeError: undefined is not a function

如何在模型中的路由中使用jQuery函数

提前感谢。

jQuery不能很好地与Node JS配合使用，我建议使用Lodash-

请记住，jquery需要一个文档窗口才能正常工作。
您可以使用jsdom来实现这一点：

var jsdom = require("jsdom"),
    $     = require('jquery')(jsdom.jsdom().parentWindow);

看看：

var jsdom = require("jsdom"),
    $     = require('jquery')(jsdom.jsdom().parentWindow);
