The example in this article describes how JS obtains image alt information. Share it with everyone for your reference. The details are as follows:

The following JS code can obtain the prompt information of the image through the alt attribute of the image

<!DOCTYPE html>
<html>
<body>
<img id="compman" src="compman.gif" alt="Crazy computerman" 
width="107" height="98">
<p>The value of the alt atrribute is:
<script>
document.write(document.getElementById("compman").alt);
</script>
</p>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
