Обрезать свой код ответа и проверить условие

 success: function(msg) {
                        if($.trim(msg) == '1') {
                            console.log("done");
                        } else {
                            console.log("fail");
                        }   

                }

    url:        "test.jsp",
    data:           "name="+name,
    success:    function(msg) {

        // msg is returned by the ajax function
        // this holds the returned data

        alert(msg);

        // Compare the msg variable to see if it returned condition
        // this compares the ENTIRE text of return, if it has any more
        // characters in it, this condition will never be met!
        if(msg == "available"){
            alert("Yes!");
        }else{
            alert("No :-(  ");   // Sad face :(  The return was something different
        }

    }
});
