So I like to append data(JSON) I received from the server to new pop up window. I tried what other people already posted but none of them actually works.
$.ajax
    ({
        url: "/receiveData",
        type: "POST",
        contentType: "application/json; charset=UTF-8",
        data:myJSON,
        dataType: "json",
        success: handledata
    });
so I have this ajax call and handle data
This is what i have on handledata function and I like to append this to specific id called "user" in open.html
var newin = window.open("open.html");
$(newin.document.body).ready(function() {
    //$(newin.document.body).append("<tr>"+ "Hello"+ "<tr>")
        newin.alert("hello");
});
