如何将 Mongoose 集合传递给 js 文件中的函数？

Question

我正在做一个项目，我希望能够根据类似于您在 Revzilla.com 上选择顶部的我的车库后找到的表单输入来搜索摩托车数据库。该表格将在项目的多个位置使用。

我将 bikeLists 传递到我的 routes/index 文件中的索引


const express = require('express');
const router = express.Router();
const bikeDBModel = require('../models/bike')
const mongoose = require('mongoose');
const { collection } = require('../models/bike');

const BikesDBConnection = mongoose.connection.useDb('bikes')


router.get('/',(req,res)=>{;
    const collection = BikesDBConnection.collection('harley-davidson')//Harley is the only Maker supported at the moment(change to all-bikes) soon.
    res.render('index', {'bikesList':collection})
});

module.exports = router;

我可以让它显示在我的 view/index.ejs 文件中


<%= bikesList %> 

<%- include('./partials/part-bikeSelector.ejs') %>

**更新：**根据我的研究，我发现您应该能够通过执行以下操作使其正常工作，但我仍然得到“bikesList not定义”错误


<%- include('./partials/part-bikeSelector.ejs', {bikesList:bikeList) %>

但无法获取到part-bikeSelector.ejs下的包含文件


<%= bikesList %> 

<form action="" method="post" class="bikeSelectorForm">
    <div class="yearSelect">
        <select name="bikeYear" id="bikeYear" onchange="getBikeModels()">
            <option disabled selected value>Year</option>
            <% for( let i = new Date().getFullYear(); i >= 2000; i-- ) { %>
                <option value="<%= i %>"><%= i %></option>
            <% } %>
        </select>
    </div>
    <div class="makeSelect">
        <select name="bikeMake" id="bikeMake">
            <option disabled selected value>Motorcycle Make</option>
            <option value="Harley">Harley Davidson</option>
            <optgroup label="Coming Soon">
                <option disabled value="Yamaha">Yamaha</option>
                <option disabled value="Honda">Honda</option>
                <option disabled value="Kawasaki">Kawasaki</option>
                <option disabled value="Indian">Indian</option>
            </optgroup>
        </select>
    </div>
</form>

<script src="/js/bikeSelector.js"></script>

理想情况下，我想将它进一步传递给从部分链接的纯 js 文件-bikeSelector.ejs


const bikeYear_formField = document.getElementById('bikeYear');

//get list of models based on year and make of form fields
function getBikeModels() {
    console.log(bikesList);
}

完全看错了。答案是重新考虑我的方法。我创建了一个 REST API，我可以在需要时获取所有数据。
