在iframe中查找具有其Id的元素位置

Question

I am using the below to get its position away from the Top

var posTop = document.getElementById('elementId').getBoundingClientRect().top 
- document.body.getBoundingClientRect().top

How is it possible to get its position if the element is inside an iframe and the iframe is not in the same domaine ?

Answer 1

you can access to other iframe just if the other domain accepted cross-origin. so, if it's not your domain, you probably need to ask them to allow that, if possible
