如果用户输入 mongodb 中的表单相等对象，则返回 true

Question

我有一个 EJS 页面设置，用户可以使用按钮/文本进行各种选择，并且基于这些选项，我想查询 mongoDB 集合，并在用户输入与对象中的数据匹配时返回 true？

表单

<% layout('/layouts/boilerplate')%>
<form action="/caddy" method="get">
<div class="position">
    <label for="tablePosition">Hero Position</label>
    <input type="text" class="form-control" placeholder="Enter Your position" aria-label="Example text with two button addons">
    <button type="button" class="btn heroBTN" id="btn">UTG</button>
    <button type="button" class="btn heroBTN" id="btn">HJ</button>
    <button type="button" class="btn heroBTN" id="btn" >LJ</button>
    <button type="button" class="btn heroBTN" id="btn">CO</button>
    <button type="button" class="btn heroBTN" id="btn">BTN</button>
    <button type="button" class="btn heroBTN" id="btn">SB</button>
    <button type="button" class="btn heroBTN" id="btn">BB</button>
</div>
<div>
    <button submit="button" class="btn btn-primary">submit</button>
</div>
</form>

架构

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const RangesSchema = new Schema({
    position: String,
    playertype: String,
    unsuited_hands: [String],
    suited_hands: [String]
});

module.exports = mongoose.model('Ranges', RangesSchema);

JS

router.get('/caddy', function(req, res) {
  db.collection('rFI').find({"Position": { $regex: req.query.position ,$options: 'i' }}).toArray( (err, results) => {
      console.log('got search')
      res.send(results)});
  });
