'Print Templates using esri.request' sample not working in Internet Explorer?

Question

Hi

I have just viewed the above sample fine in Google Chrome but when trying to view it in Internet Explorer I get a blank map with a javascript error (attached).

Is this a known issue? I am using IE7.

Thanks

This is not true�?? while IE7 doesn't support most of the technologies commonly referred to as "HTML5", the simple doctype works for IE7. For example, see our sample that shows new query functionality at 10.1:  http://help.arcgis.com/en/webapi/javascript/arcgis/demos/query/query_statistics.html

That sample uses the simple doctype and works w/o issue in IE7. As Kelly pointed out, the real issue is the trailing comma.

Be especially carefully with trailing commas in JSON.  It will break IE every time.

I highly recommend a json validator like

This line:<!doctype html>

at the top of the page says the page should be rendered using HTML5. IE7 does not support HTML5.

Looks like the sample has a trailing comma - IE has a problem with those. You'll find the extra comma in the section of code that creates the print widget. Remove the comma after url:app.printUrl and the app should run in IE. 
 app.printer = new esri.dijit.Print({
          "map": app.map,
          "templates": templates,
          url: app.printUr,  <---- Trailing comma is here---->
        }, dojo.byId("print_button"));
        app.printer.startup();
      }

We'll get the official sample fixed as soon as possible.
