CAMLquery nested AND

Question

I want to get all the items from my list, like this (A&B) AND (C&D), but my CAMLquery doesn't seem to work, here is what I've tried so far:

var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml(
"<View>" +
"<Query>" +
"<Where>" +
"<And>" +
"<And>" +
"<Eq><FieldRef Name='Prioritet'/><Value Type='Text'>A</Value></Eq>" +
"<Eq><FieldRef Name='Status'/><Value Type='Text'>B</Value></Eq>" +
"</And>" +
"<And>" +
"<Eq><FieldRef Name='Prioritet'/><Value Type='Text'>C</Value></Eq>" +
"<Eq><FieldRef Name='Status'/><Value Type='Text'>D</Value></Eq>" +
"</And>" +
"</And>" +
"</Where>" +
"</Query>" +
"</View>");

Answer 1

the syntax is each < and> statement content 2 queries.

section <and> is one query in another <and> statement

change the query to:

"<View>" +
  "<Query>" +
    "<Where>" +
        "<And>" +
            "<And>" +
                "<And>" + <------first
                    "<Eq><FieldRef Name='Prioritet'/><Value Type='Text'>A</Value></Eq>" + <----- 1
                    "<Eq><FieldRef Name='Status'/><Value Type='Text'>B</Value></Eq>" + <------2
                "</And>" +
                "<Eq><FieldRef Name='Prioritet'/><Value Type='Text'>C</Value></Eq>" + <----- second
            "</And>" +
            "<Eq><FieldRef Name='Status'/><Value Type='Text'>D</Value></Eq>" +
        "</And>" +
    "</Where>" +
  "</Query>" +
"</View>"
