Answer 1

var idPost=document.getElementById("status").innerHTML;

The 'status' element does not exist in your webpage.

So document.getElementById("status") return null. While you can not use innerHTML property of NULL.

You should add a condition like this:

if(document.getElementById("status") != null){
    var idPost=document.getElementById("status").innerHTML;
}

Hope this answer can help you. :)
