JavaScript部分
获取 html 的信息
const container = document.querySelector('.container');// 获取座位信息
const seats = document.querySelector('.row .seat:not(.occupied)');// 获取座位已经出售的信息
const count = document.getElementById('count');// 获取选择座位的个数信息
const total = document.getElementById('total');// 获取选取座位的价格总和信息
const moviesSelect = document.getElementById('movie');// 获取电影信息
将票价的类型由 object 转化类型为 number
// const ticketPrice = moviesSelect.nodeValue;// 获取票价信息
// console.log(typeof ticketPrice);//类型是 object
// 转化类型为 number
const ticketPrice = +moviesSelect.value;
console.log(typeof ticketPrice);// number
点击页面的座位的任何位置都可以在控制台显示相关信息
// 给 container 加上事件，完善相应功能
container.addEventListener('click',(e)=>{
console.log(e.target);//
});
但是需要的只是座位信息，不需要点击屏幕也显示信息
container.addEventListener('click',(e)=>{
if (e.target.classList.contains('seat')){
console.log(e.target);
}
});
还有的就是需要将已售的座位信息也去掉
container.addEventListener('click',(e)=>{
// 设置为可以点击没售出的座位，控制台显示信息
if (e.target.classList.contains('seat') && !e.target.classList.contains('occupied')){
console.log(e.target);
}
});
将选择的座位进行属性切换，属性的更换已在css样式中设置好了
container.addEventListener('click',(e)=>{
if (e.target.classList.contains('seat') && !e.target.classList.contains('occupied')){
e.target.classList.toggle('selected');
}
});
将选择的座位统计起来
将选择的座位查看信息
// 更新已选座位数
function updateSelectedCount(){
const selectedSeats = document.querySelectorAll('.row .seat.selected');
console.log(selectedSeats);
}
container.addEventListener('click',(e)=>{
// 设置为可以点击没售出的座位，控制台显示信息
if (e.target.classList.contains('seat') && !e.target.classList.contains('occupied')){
e.target.classList.toggle('selected');
updateSelectedCount();
}
});
统计已选择的座位数
// 更新已选座位数
function updateSelectedCount(){
const selectedSeats = document.querySelectorAll('.row .seat.selected');
//console.log(selectedSeats);
const selectedSeatsCount = selectedSeats.length;
console.log(selectedSeatsCount);//统计已选择的座位数
}
container.addEventListener('click',(e)=>{
// 设置为可以点击没售出的座位，控制台显示信息
if (e.target.classList.contains('seat') && !e.target.classList.contains('occupied')){
e.target.classList.toggle('selected');
updateSelectedCount();
}
});
更新座位数和价格部分，根据选择的座位计算总价
// 更新已选座位数
function updateSelectedCount(){
// 统计已选择的座位数部分
const selectedSeats = document.querySelectorAll('.row .seat.selected');
//console.log(selectedSeats);
const selectedSeatsCount = selectedSeats.length;
console.log(selectedSeatsCount);//统计已选择的座位数
//更新座位数和价格部分
count.innerText = selectedSeatsCount;
total.innerText = selectedSeatsCount * ticketPrice;
}
container.addEventListener('click',(e)=>{
// 设置为可以点击没售出的座位，控制台显示信息
if (e.target.classList.contains('seat') && !e.target.classList.contains('occupied')){
e.target.classList.toggle('selected');
updateSelectedCount();
}
});
选电影事件
将之前的代码由 const 改为 let
//const ticketPrice = +moviesSelect.value;
let ticketPrice = +moviesSelect.value;
//选电影事件
moviesSelect.addEventListener('change',(e) => {
ticketPrice = +e.target.value;
// 调用函数
updateSelectedCount();
});
