How to change image source using JavaScript?

Question

I Need to change image source using JavaScript for example
HTML
<img id="picture" src="http://someurl.com" width="300" height="300" />
JS
var file = document.getElementById("picture")
//now goes something that i dont understand
file.src = "otherURL"
I think that everything in this JS is incorrect . Can you tell me how to change source in JS?

Answer 1

ivankoshan First of all, you can't include a picture from your device on sololearn. The source of the image should be online means it should be uploaded somewhere else on the net not on your device.

If you want to change your image with js. You can see the small code I have made for you. Feel free to copy.

Answer 2

you cannot change an images source like that.
you can only assign the image to a different/another source.
