Suggestions for debugging a dojo parse error?

evtguy

I'm revisiting an application I started putting together using the 2.8 API. I'm not quite ready for AMD dojo so I was updating the API version to 3.4 but now I get a dojo parse error pretty much as the page loads. The error points to the API but I realize that's not the true source of the issue. While reading some of the documentation about dojo.parser, I got the impression that it's focused on the HTML side of your development and not necessarily the javascript code that you write. Is this correct?

I don't have a ton of dojo items (borderContainer, ContentPane, BasemapMenu, DataGrid) so it shouldn't be this hard to figure it out but I'm having a hell of a time doing so.

Should I be focusing my attention on the HTML markup or my javascript code? I've tried setting a breakpoint on the first line of code in my init() function but the parse error already fires before the code execution hits the breakpoint.

Thanks!
Steve

Hey Steve,

I did a quick search and found something under the archives.

Using lang="en" can break apps that use when using layout dijits and data-dojo-config(or dojoConfig) locale or extraLocale is not set. The recommended fix is to set locale or extraLocale on data-dojo-config or remove the lang="en" attribute. The specific error seen when this is an issue is "dojo/parser::parse() error TypeError" in Chrome and "TypeError: _72f(...) is undefined" in Firefox. More information is available in the Dojo bug tracker: http://trac.dojotoolkit.org/ticket/15630#comment:7 http://trac.dojotoolkit.org/ticket/15768#comment:6

See if that helps at all.

If not, I'll take another look.

Also, if you haven't seen this, it may be worth a look: https://developers.arcgis.com/en/javascript/jshelp/migration_30.html

I'm actually using AMD myself, but I didn't know if there was a way to keep that line in. I had to take out the language tag too.

evtguy

Man- this is a blast from the past.

My memory is fuzzy about this (especially since I also upgraded this to AMD from legacy) but I think the only thing I needed to do was remove this line from my original header:

<html lang="en">

ChrisSergent

Did you just remove the lang='en' as well?

ChrisSergent

This is still an issue in 3.14.

evtguy

ARGH!!

I totally forgot about that part of the migration to the 3.x APIs. I removed the reference and all is well.

THANK YOU!

The header is a bit of a mess (this is one of my first webmap app efforts) because it tries to apply some responsive design to the page.

EDIT: Forgot the actual error:

dojo/parser:parse() error TypeError {} serverapi.arcgisonline.com/jsapi/arcgis/3.4/:34

Hey Steve,

Could you post your code and/or the exact parser error you are receiving?

Like you said, many parser issues result from incorrectly formatted HTML but it could be as simple as you invoking the parser at the wrong time.

KennethRichards

I'm having a similar problem right now. I do know that it is something in the html so I would focus there first.
