How to use jquery variable value

Question

I am having trouble using the value that is inside my variable when I use it jquery

var id_pais =  $('#endUF option[value=id_pais]').text();
        $('#endUF option[value=id_pais]').remove();
        $('#endPAIS option[value=id_pais]').prop('selected', true);

In case I take the value of my system and put it in a js variable. But then I can’t reuse it in jquery. I read about it and saw that when I use value in jquery, like the one used above, jquery sees it as a string and does not take the value of the variable.

The variable was missing. Try the following:

var id_pais =  $('#endUF option[value=' + id_pais + ']').text();
        $('#endUF option[value=' + id_pais + ']').remove();
        $('#endPAIS option[value=' + id_pais + ']').prop('selected', true);
