Question

Dictionary to Json object, "Expected expression"

Answer 1

+1 A:

It means that the JSON in the output isn't well-formed, either because the original is malformed or because it's not being output correctly (or at all, per Pointy's comment). See this answer for a list of common errors. Since you're using Javascript itself, not JSON, some of them won't apply to you, but some will. My guess is a dangling comma; we need to see the JSON to know.

You can validate JSON with this validator, and learn more of the required syntax on the JSON site.

It could be that his construct there is resulting in nothing at all, so that the resulting Javascript is just `sortFields = ;`.

Pointy 2010-05-26 16:20:13

@Pointy: Indeed, or an unquoted string.

jsonlint.com validated his json fine, btw

Answer 2

A:

{"Name":"Ascending","ClassDesignation":"Ascending","ShareType":"Ascending","Curr":"Ascending","DateFirstPriced":"Descending","Identifier":"Ascending","OneWeakPerf":"Descending","OneMonthPerf":"Descending","ThreeMonthPerf":"Descending","SixMonthPerf":"Descending","YTDPerf":"Descending","OneYearPerf":"Descending","ThreeYearPerf":"Descending","FourYearPerf":"Descending","FiveYearPerf":"Descending","TenYearPerf":"Descending","SinceLaunchPerf":"Descending","OneYearAnnualisedPerf":"Descending","ThreeYearAnnualisedPerf":"Descending","FiveYearAnnualisedPerf":"Descending","TenYearAnnualisedPerf":"Descending","SinceLaunchAnnualisedPerf":"Descending"}

This is the way the JSON looks like, and I can't see any issue with it. But I'm not too familiar with JSON either, so don't know for sure.

Have you verified that it looks exactly like that when you do a "view source" on your page?

Pointy 2010-05-26 16:26:02

Also, when adding information to a question, you shouldn't provide an "answer" like this, because obviously it's not an answer to your original question. Just edit your question (click the little "edit" link underneath it).

Pointy 2010-05-26 16:27:35

Cool. Sorry about that. Viewing the source doesn't seem to give my much at all.

MrW 2010-05-26 16:32:30

Well that right there may be your problem :-) You should see, in the source, `sortFields = {"Name":"Ascending", ... };` and if you don't then something's wrong with that server-side expression.

Pointy 2010-05-26 16:33:48

Might this be due it's all in a partial view that causes it not to be displayed in the source? As it seems I can't see any of the information from that page.

MrW 2010-05-26 16:35:36

If I'm using FireBug, I can see the object listed in the items under the DOM tab. with the expected values as well.

MrW 2010-05-26 16:38:07

The *DOM* tab? Do you mean the "HTML" tab? In the HTML tab, when you find your `<script>` element and open it up, do you see the code there?

Pointy 2010-05-26 16:47:09

Yea I know. But the global variable is available in the DOM tab as well. Anyway. Don't know why. I've rolled back my code done back and forward and now suddenly works. When I compare the previous version with this, they are the same. I'm sorry for taking your time. It works no at least!
