Help Combining Find and Identify Task Samples

JHayes — Tue, 30 Apr 2013 16:14:05 GMT

Hello,

I've been trying to combine the Identify and Find Task examples, but have yet to get the Identify Task to work. I'm not sure where I've gone wrong, so any help would be awesome.

Thanks,
Joe

Hi Joe,

You just need to call your mapReady function with dojo.connect. Ex:

dojo.connect(map, "onLoad", function() {           //Create the find parameters           findParams = new esri.tasks.FindParameters();           findParams.returnGeometry = true;           findParams.layerIds = [0];           findParams.searchFields = ["NUMBER_KEY","FIRST_NAME"];           findParams.outSpatialReference = map.spatialReference;           console.log("find sr: ", findParams.outSpatialReference);           mapReady(map);         });

Hay Jake,

While I've got you here;

Could you point me in the right direction for the best way to "optimize" this code for mobile devices?

Thanks,

Any ideas on why this will not run, at all, in IE8? I changed the meta tag at the top to include IE8, but still not dice.

<!DOCTYPE html>

    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=7, IE=8, IE=9, IE=10">

Thanks.
