JavaScript接下来的小项目

本文主要是介绍JavaScript接下来的小项目，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

● 接下来，我们将学习如下所示的一个小项目，这个项目是一个地图的项目，我们可以在地图上标记一些我们运动的位置进行记录，并且浏览器在本地会帮我们记录他们，其他一些功能后面慢慢阐述并实现

启动代码

JS代码

'use strict';// prettier-ignore
const months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];const form = document.querySelector('.form');
const containerWorkouts = document.querySelector('.workouts');
const inputType = document.querySelector('.form__input--type');
const inputDistance = document.querySelector('.form__input--distance');
const inputDuration = document.querySelector('.form__input--duration');
const inputCadence = document.querySelector('.form__input--cadence');
const inputElevation = document.querySelector('.form__input--elevation');

CSS代码
