I need to make this parison:

if (x < siteA.style.left || x > siteA.style.left + land.width() ) {

however siteA.style.left returns 20px (e.g) so the condition doesn't work. How do I remove the px and transform it into an integer so I can work with it?

I tried alert(parseInt(siteA.style.left)) and it returned NaN however alert(siteA.style.left) returned 30px, 60px etc.

Use parseInt:

var leftPos = parseInt(siteA.style.left, 10);

where 10 is the base, good practice to always specify it.

Just use parseInt().

Have you tried this?

var left = parseInt(siteA.style.left.replace('px', ''), 10)

When using jQuery you can use $('#siteA').offset().left which returns only the integer value.
