In a tree built with jsTree, I have the text within the <a> tag sitting in a variable. I would like to check that node. How can I do so?
I am currently finding that node, using jQuery, and altering its class. However, this does not repair the parent node by making the parent undetermined in its class. I tried doing $('.colors').jstree("checkbox_repair"), but that didn't seem to do anything.
It would be great if someone could actually answer both those questions, since they are related to the same problem.
Here is a jsFiddle, illustrating the issue--> http://jsfiddle.net/thapar/5XAjU/
In js_tree there are .check_node ( node ) and .uncheck_node ( node ) functions, i think this is what you are asking for. Soe the documentation here: http://www.jstree.com/documentation/checkbox
This is an excerpt from the documentation in the link above, "how to perform an operation":
/* METHOD ONE */
jQuery("some-selector-to-container-node-here")
.jstree("operation_name" [, argument_1, argument_2, ...]);
/* METHOD TWO */
jQuery.jstree._reference(needle)
/* NEEDLE can be a DOM node or selector for the container or a node within the container */
.operation_name([ argument_1, argument_2, ...]);
So I think this syntax should work
$.jstree._reference(".colors").check_node('li#tree_3');
Also i am not sure you should be using a class to reference your tree. Probably use an ID to reference your tree, and then use this syntax:
$.jstree._reference("#colors").check_node('li#tree_3');
//EDIT: Please keep in mind that the newest version of jsTree doesn't have a function called _reference anymore. It got renamed to reference (without the leading underscore). (Last checked 24/08/2015 15:45 by @mkli90) Link: https://www.jstree.com/api/#/?f=$.jstree.reference(needle)
