The output format in release 8.0.2 is still the same, with @. Compared to the JSON of 7, the JSON of 8 now starts with @timestamp, next is @toplevelentries. In 7, it starts with @toplevelentries.

Boyzl. Try:

Print "Content-Type:text/plain; charset:windows-1250"

Note the semicolon and the unquoted charset name!

Hi everyone,

I use JSON responses on Domino 6 but have a problem. Anyone has an idea how to properly include 'charset' or 'codepage' setting in header? Something like Print "Content-Type:text/plain charset:'windows-1250'"?

I need it cause I want to return text with national characters by means of JSON object.

Thanks,

regards from Slovenia,

Bojan

To Mark V. I may have misunderstood the Leveraging AJAX Frameworks to Build IBM Lotus Domino Web Applications presentation, but I was pretty sure the speaker mentioned that they were going to remove the @ from the "@position": '1', "@unid": '211F916D90F4425E8625726F0058B298', ... type elements.

I will follow up with the speakers

@Mark C - there are no plans to remove the @ for version 8.

One of my previous posts described the changes in 8.

FYI, I am a member of the IBM Domino Web Server development team.

Mark. I see now. My code didn't need the eval() call as all the JSON code was in-line and so already treated as a JavaScript object. Didn't think to mention the eval(), which is needed when the JSON is fetched from Domino as plain text.

BTW, in case your source didn't tell you, they are changing the json outputformat in 8. They are removing the @ from the front of the name since JS doesn't allow @ to be the first character.

So whatever works now may need to be revisited when Domino 8 is installed.

Yes, it was. I'm not sure who or what was inserting the newline char. I'm a little weak at advanced JS. Here is how I got it to work:

var pos = "";

var myjson = xmlHTTP.responseText ;

otherjson = eval("(" + myjson+ ")");

view["data"]=otherjson ;

var documents= view["data"].viewentry ;

for (var i=0; i

{

alert('in loop: ' )

pos += documents[i].entrydata[1].text[0] ;

}

$("viewtable").innerHTML = pos ;

So, per wikipedia, I ran an eval on what was returned back to me. I then modifed your example to point view["data"] to the eval return, rather than what was returned from Domino. I'm developing in 7.0.2 and FF 1.5.0.9

Any ideas?

Mark. \n is a newline in JavaScript. Is it causing your problems?

Has anyone put this to use? I'm trying to stuff the json (from an ajax call) and am not having much success. Looking through one of the debugging tools, I see \n in front of the json code:

"{\n"@toplevelentries": 11,\n"@rangeentries": 2,\nviewentry: [\n{\n"@position": '9',\n"@unid": 'CF57E86AE56..."

Any ideas

I actually find the ?readViewEntries stuff interesting for integration.

I have some java code (but this is possible with other languages too) which downloads and parses the ?ReadViewEntries from some forums on notes net with a sax parser and writes all the information in documents of a notes database. It actually also downloads the body of the postings which is admitedly not in the ?ReadViewEntries.

At my job we are using bugzilla. From that system I also get data in xml form. I can again download and parse that data on a scheduled basis and replicate it in a notes database where I can add some extra-functionality like giving people the chance to assign a business value and estimated costs to the bug entries for prioritizing. Thats not ?readViewEntries, but the same idea.

Thanks for the usage examples and link!

Hmm. Not sure I'd use it to create a table of a view like the example. Not a practical example by any means.

This JSON view stuff is exciting as it makes it much easier to work with AJAX and Domino. We can get view entries from Domino in JSON format *without* messy agents AND we can use extra URL parameters like &Startkey= to really narrow down "search" results.

Lots of other uses to. Such as pagination of views. In conjunction with Jack Slocum's Grid it would be really nice!

Thanks for the example...would you use this method just as a way of getting a better handle on layout and presentation as compared to a regular view? Or do you have any examples on why developers should use this?

Thanks!
