I want to be able to change an object's position using JavaScript. I thought I found the answer here:

https://community.adobe.com/t5/captivate/captivate-scripting-change-x-y-position-of-object/td-p/8606684?page=1

When I tried it, I got a blank. I'm not sure what the reason is.

var obj = document.getElementById( 'Image_12c' );
var posX = parseInt( obj.style.left );

alert(posX);

I think it's just because posX has the value 0 at this stage. Try console.log intead of alert and check in the browser's console.

If you fired obj.style.left = ( posX + 10 ) + 'px'; at it now like advised in the post you cited, your image should jump 10 pixels over to the right as expected.

If you run this script on slide enter, you might have to wrap it in a timeout to give the image time to load.

When I check console.log, it says NaN.

When I use this:

var obj = document.getElementById( 'Image_12c' );
console.log(obj);

I get this:

(unknown) 
<canvas id="Image_12c" class="cp-shape" width="196" height="156" style="left: 0px; top: 0px; right: 0px; bottom: 0px; width: 100%; height: 100%;">
