I basically need to disable(not deselect) all my selected child nodes when I click on the parent node. 回答1: You need to create a new type(disabled) for this. It can be done as follows "types" : { "types": { "disabled" : { "check_node" : false, "uncheck_node" : false } } } and then assign that type as .set_type("disabled", "#node5"); More documentation is here. For disabling all child nodes, create an event handler for the change_state event $("#treeElement").bind("change

I need to prevent a user from changing to another node before a certain condition is met. The below code does not stop the propagation... i saw some solutions with other plugins but this is a simple task it must be possible without other plugins. $('#jstree').on('select_node.jstree', function (e) { if (!changeAllowed() { e.preventDefault(); e.stopImmediatePropagation(); } }); 回答1: Documenting for myself and posterity: you need to include the following function AFTER loading the

I then try to bind to the "move_node" event to update my database: .bind("move_node.jstree",function(event,data){ if(data.rslt.obj.attr("id")==""){ /* I omitted this snippet from this paste - it's really long and it basically does the same thing as below, just gets the node's id in a more complicated way*/ } else {

I am totally new to jQuery and jstree. I am using jstree and populating the data using xml. But would like to capture event for each node whether checked or not along with their Ids. I tried using jstree's plugins API like change_state() , check_node() or select_node() but it's not working. Also I would like to get all selected nodes data in an array for further processing..Can anyone help? Thanks... Toadmyster I like the jstree plugin but it's not well documented, nor is it built to conform to say, jquery ui standards of plugin development. I have used 1.0rc2 to accomplish what you're trying

I am trying to dynamically load the nodes of a jtree when they are expanded. The little documentation I found is at the end of this page . I found some solutions that create the nodes one by one with a loop like this one . I have not tried it, but looking at the documentation page I have the feeling that jstree should take care of cycling through the nodes. I found many solutions that use plugins: ["json_data"] , but the plugins documentation page doesn't mention that plugin at all. Is that an old plugin that is not required anymore? My current implementation uses this code to load the whole

I have a jstree that I created with the following code: $('#mytree').jstree({"core": { "data" : value , "themes" : { "dots": false , "icons": false } } } ); I can rebuild it with new data by this code: $('#mytree').jstree(true).settings.core.data = new_data; $('#mytree').jstree(true).refresh(); but it can be expensive when you have a lot of nodes. What I would like to achieve is that I would like update the value of the elements (i.e. the node.text part) without rebuilding the whole tree. I get the new values via websocket in one message (the complete JSON string that will be the new_data )

If a node's descendent is checked, then that node should be in an "undetermined state" (like ACME and USA). The problem is, the tree starts out collapsed. ACME looks unchecked but should be undetermined . When I finally expand to a checked node, jsTree realizes the ancestors should be undetermined . So I need to be able to put a checkbox in the undetermined state without loading its children. With jsTree you can pre-check a
