We haven't really done a design for a JSON data API, but Openlaszlo does use JSON internally for some things; the Java RPC and XMLRPC services actually consume JSON sent from the server. So there is a JSON parser (in lps/components/rpc/library/json.js) which works in all the runtimes. If you're using the DHTML runtime, the code which loads <import> libraries at runtime uses a routine to load a script file from a server, it is lz.embed__dhtmlLoadLibrary(url) (defined in lps/includes/source/embednew.js, as part of the HTML wrapper ). I suppose that might work to load a JSON document as well if there were some convention as to where the JSON value gets stored when it is loaded. But we definitely should look at how to integrate JSON data better. > > Regards and best wishes, > > Justin Clift > > >> >> >> >> On Mon, Jan 12, 2009 at 1:43 PM, Justin Clift <[email protected]> wrote: >>> Hi all, >>> >>> Trying to figure out how to do HTTPS requests (for securing >>> authentication) from an in-development web app. >>> >>> Older documentation and references exist online, pointing to the >>> existence of a "secure" attribute for the <dataset> tag.
