Answer 1

you can use $.get() something like this

$.get('Rest.baseURL', function(response){

//

});

Answer 2

Here is what you wanted.

$('#ajax').click(function() { 
    $.ajax({
        type: "GET",
        dataType: "json",
        url: "localhost:8080/restws/json/product/get",
        success: function(data){
            let result = JSON.parse(data);
            if(result != null) {
                Rest.rests = result;
                createTable();
            }
        }
    });
});
