  • 0

I have a jstree tree that I’m trying to extract the structure of using get_json (in order to post it back to the server), but I don’t seem to be getting any tree info in the returned object.

The tree is setup and working properly in 

$("#site-structure-container").jstree({plugins : ["themes", "json_data"]});

(excluded above is the json I’ve supplied (from the first demo here) to setup the tree) and I’m using 

data = $("#site-structure-container").jstree("get_json", -1);
console.log(JSON.stringify(data));

to check whats extracted. This is what is shown in the log:

{"length":1,"0":{"jQuery16203561271743551655":3},"context":{"jQuery16203561271743551655":1},"selector":"#site-structure-container"}

Surely I should be getting the tree structure in here? What am I doing wrong?

UPDATE:

Have eventually tracked it down to jQuery version.. 1.6.2 (which I was using) doesn’t appear to work in the same way that 1.4 to 1.6.1 do. Changing to any 1.4 to 1.6.1 means I get the result I expected ie.:

[{"data":{"attr":{},"title":"A node","icon":"checkbox"},"attr":{"id"...

I don’t know exactly what is going wrong with 1.6.2+, but I’ve found it doesn’t make any difference whether I use .jstree("get_json") or .jstree("blahblah") or .jstree(), I always get the same unexpected output as above ({"length":1...).
