Is there a way set attributes only using JavaScript?

Hi Vic,

Here's a basic example

<img src="" id="myImg" />

document.getElementById("myImg").src = "http://www.google.com/image.png";
document.getElementById("myImg").alt = "This is some alt text";

You can also use attribute selectors in jquery or querySelector/querySelectorAll in vanilla js - see here.

Hope this helps :)

Hey Vic,

I'd take a look at this tread on Stack Overflow. You can assign and ID to your image and then change your SRC and ALT using JavaScript:

document.getElementById("imageid").src="../template/save.png";

Hope that helps! Happy coding!
