26 |
* It is possible to set this to a standard jQuery-like AJAX config.
|
|
|
27 |
* In addition to the standard jQuery ajax options here you can supply functions for `data` and `url`, the functions will be run in the current instance's scope and a param will be passed indicating which node IDs need to be loaded, the return value of those functions will be used.
|
|
|
28 |
*
|
|
|
29 |
* You can also set this to a function, that function will receive the node IDs being loaded as argument and a second param which is a function (callback) which should be called with the result.
|
|
|
30 |
*
|
|
|
31 |
* Both the AJAX and the function approach rely on the same return value - an object where the keys are the node IDs, and the value is the children of that node as an array.
