Image in span tag into an img tag
Question
I try to display an image with <img src="" alt="music cover"> using <span></span> to display the music covers of my web radio.
The link is dynamic, it's why I want to use the span tag for getting the url link of the image's shown during music playback.
I've tried this, but it doesn't work:
<center>
<p class="current-playlist">
<span></span>
</p>
</center>
Here is my code:
<!DOCTYPE html>
<html>
<center><p class="current-playlist"><img src="<span></span"></p></center>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script>
var nowPlayingTimeout;
var nowPlaying;
function loadNowPlaying() {
$.ajax({
cache: false,
dataType: "json",
url: 'https://my_radio_website.com/api/nowplaying_static/radio.json',
success: function(np) {
// Do something with the Now Playing data.
nowPlaying = np;
$('.current-playlist span').text(np.now_playing.song.art);
nowPlayingTimeout = setTimeout(loadNowPlaying, 15000);
}
}).fail(function() {
nowPlayingTimeout = setTimeout(loadNowPlaying, 30000);
});
}
$(function() {
loadNowPlaying();
});
</script>
</html>
Without the img tag, only the image link is shown, how could I proceed?

<img src="<span></span"> is not a valid HTML, you can not put another element into src tag, you should only set image link to src instead.
To do that, you can crate an <img src=""> element with an empty src attribute.
Then, when you need to load the image you can put the image link into src attribute.
Example:
const imageLink = "https://picsum.photos/200/300"; // setTimout to simulate ajax request setTimeout(() => { $(".current-playlist img").attr("src", imageLink); // OR document.querySelector('.current-playlist img').src = imageLink; }, 1000);
