How can I change the source of a video after clicking a specific h3 tag?-CodePudding

So I'm currently trying to make a video streaming site but I'm a bit stuck.

I'm trying to make the episode selector change the source of the video but I am a little confused as to how I can make it change the source of the player. I'm also trying to make the text below the player change depending on which video is selected.

    <div class="container">
        <div class="main-video">
            <div class="video">
                <video src="video link here"></video>
                <h3 class="ep-title">00. Prologue</h3>
            </div>
        </div>

        <div class="episode-list">
            <div class="episode active">
                
                <img src="image link here" alt="">
                <h3 class="title">00. Prologue</h3>
            </div>
            <div class="episode">
                <img src="image link here" alt="">
                <h3 class="title">01. A Winter Day, A Fateful Night</h3>
            </div>
            
            </div>
        </div>
    </div>

<script>
    let listVideo = document.querySelectorAll('.episode-list .episode');
    let mainVideo = document.querySelector('.main-video video');
    let title = document.querySelector('.main-video .title')

    listVideo.forEach(video =>{
        video.onclick = () =>{
            listVideo.forEach(episode => episode.classList.remove('active'));
            video.classList.add('active');
            };
        
    });
</script>

This is what my code for the page (excluding the nav bar and plyr code) currently looks like. I do apologise beforehand as my question might be a bit complicated (I lack braincells lol) but any help is appreciated :)

const btn = document.getElementById('change-url');
const video = document.getElementById('video');


btn.addEventListener('click',()=>{
   console.log(video)
   video.setAttribute('src','http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/Sintel.mp4');
})

<button id="change-url">change url</button>
<br/><br/>

<video id="video" src="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" width="300px" controls autoplay></video>

I think mainVideo.setAttribute('src', YOURSOURCELINK); should change the video src. To change the text of the title you can use title.innerHTML = "NEWTEXT"

An example for this could be:

the "index" argument is the index in the list (keep in mind js starts with 0 for the first index), so to get episode one you would use changeVideo(0), for episode two changeVideo(1) etc

var list = [{
    title: "Episode 1",
    src: "some source link"
},{
    title: "Episode 2",
    src: "seconde source link"
}];


function changeVideo(index){
    let mainVideo = document.querySelector('.main-video video');
    let title = document.querySelector('.main-video .title')

    mainVideo.setAttribute("src", list[index].src)
    title.innerHTML = list[index].title

}

then you would need a onclick event in your video select, for example add onclick="changeVideo(1)" in your <div >
