There are so many examples — which one should be used to get started ??

where in the code do I change the reader ?

How do I know in advance the number of pages from datasource ??

also, names are starting with “inv”. What is the meaning of “inv” ??

success: function(json, status) {
var records = json.Records;
var str = “”;
if(records ){
for(var i = 0; i ” + records[j] + “n”;
}
}
alert(str);
}
