Dynamic input for query.outFields

SamirGambhir — Tue, 26 Jun 2012 17:41:48 GMT

Hi,
I a trying to build the query.outFields as a string input based on field selection by user. e.g. If the user selects Crude Birth Rate from the form, I would like to pass field attribute as "CBR_01". I am trying to build this in JavaScript like this:

....
if (valueB=="Crude Birth Rate"){
var valOutB="CBR_01";
}
...
var myIndString = "['"+valOutB+"']";

query.outFields = myIndString;
....

This doesn't seem the right way of doing it as it does not execute the query. Any thoughts?
Thanks
Samir

Apparently, Silverlight API has a method '.add' for query.outFields. Is there a similar one for JavaScript API as well? query.outFields.add("XYZ") will be perfect but it does not work in JavaScript API.
Please help
Samir

outFields is an array of string objects, javascript uses .push() to add to an array.

Hi Matt,
Thanks for your response. Unfortunately, '.push()' did not work with my code. I tried a different route instead. I passed all fields in the query.outFields, and then checked the results against the indicators that the user selected. It has worked for me well.
Thanks for your help,
Samir
