如何在按钮点击时更改按钮上多个文本以及如何将文本存储在数据库中

<button id="myButton">点击我</button>

var button = document.getElementById("myButton");
button.addEventListener("click", function() {
  button.innerHTML = "按钮已点击";
});

var MongoClient = require('mongodb').MongoClient;
var url = 'mongodb://localhost:27017/mydb';

MongoClient.connect(url, function(err, db) {
  if (err) throw err;
  var collection = db.collection('buttons');
  
  button.addEventListener("click", function() {
    var newButtonText = "按钮已点击";
    button.innerHTML = newButtonText;
    
    collection.updateOne(
      { _id: 1 }, // 根据按钮的唯一ID进行更新
      { $set: { buttonText: newButtonText } },
      { upsert: true }
    );
  });
});
