parameters of jstree create_node

由 和自甴很熟 提交于 2019-12-05 11:07:23
问题 Could you please give me the list of parameters of this function and an example of usage $('#treepanel').jstree("create_node"); 回答1: IMHO jsTree is powerful, but documentation could be improved. The create_node function is documented here. Be careful not interpreting the [] as a literal. They are just to indicate that the parameters are optional. This works for jsTree version "pre 1.0 fixed": var position = 'inside'; var parent = $('#your-tree').jstree('get_selected'); var newNode = { state:

In my server I am returning a JSON object in the format of jsTree : {"id":"value", "text":"value", "parent":"value"} I am getting it in my view through an Ajax call.

prevent jsTree node select

I'm using the jsTree plugin to list folders in the file system. 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(); } }); Documenting for myself and posterity: you need to include the following function AFTER loading the jstree JS (from: https://github.com/vakata/jstree/blob

.bind(“move_node.jstree”,.. -> data.rslt.obj undefined. How to get node data?

由 扶醉桌前 提交于 2019-12-05 06:58:23
I have a custom functionality for check_move: crrm : { move : { "check_move" : function (m) { var p = this._get_parent(m.o); if(!p) return false; if(m.cr===-1) return false; return true; } } }, This seems to work as intended. 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 { controller.moveNode(data.rslt.obj.attr("id"),data.inst.

jsTree disable some of the checkboxes

由 血红的双手。 提交于 2019-12-05 05:25:13
Using jsTree (3.1.0+) with checkbox plugin is it possible to allow not all checkboxes to check - disable some of them? I found solution for old versions of jsTree here jstree disable checkbox but it didn't work on jsTree 3.1.0+ versions. Solution of hiding checkbox jsTree Hide Checkbox is working, but if I click on the folder, hidden checkbox will be checked anyway. Thanks. Keep in mind unless you are using checkbox.tie_selection as false , selecting and checking are the same thing. So you can simply call .disable_node() on the nodes you want disabled. EDIT : Use the latest code from the repo

Updating Ember Nested Model and Template

由 醉酒当歌 提交于 2019-12-05 05:06:26
问题 I have a template which is backed by a model. It is a tree list view which has the first level folders. I have an action handler which is used to update the sub-child any of the first level folder. From the action I need to update the model so that the sub-child is updated in the template. I can add another first level folder by directly updating the model using pushObject. How can I add/update the sub-child nodes of any parent level folders. In template: <script type="text/x-handlebars"> <h2

问题 $('#jstree_demo_div2').jstree({ 'core': { 'data': { "url": "tree.ashx?id=" + _id, "dataType": "json" // needed only if you do not supply JSON headers } }, "checkbox": { 'visible': true, 'keep_selected_style': false, }, "plugins": ["wholerow", "checkbox"] }); I need to change the url (or the variable _id will change) and then refresh data.
