jstree

问题 I am looking for like a little bit of help populating children nodes on-demand (on expand) in a jstree. I can populate the parent nodes but having no luck populating the child nodes. Scenario: I am using jstree for populating nodes in a tree. My data source is json. However, i get parent nodes from a different service and child nodes from a different service. I am using the new jstree version 3.0.0 found here: https://github.com/vakata/jstree/zipball/3.0.0-beta8 What challenge I am facing?: I

问题 I've followed the code fragment in the last example of http://www.jstree.com/demo/types to create a node of a given type and I've got no idea why it doesn't work. HTML Fragment: <form> <button id="buttonAddMenu" type="button">Créer Menu</button> <button id="buttonAddParameter" type="button">Créer Paramètre</button> <button id="buttonRename" type="button">Renomer</button> <button id="buttonRemove" type="button">Supprimer</button> <button id="buttonShowData" type="button">Show Data</button> <

问题 I'm using jsTree to show a tree with checkboxes. Each level of nodes is loaded on-demand using the json_data plugin. 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

问题 I have this structure in json I can not be modified by request. { "Object": [ { "url": "http://www.google.com" } ], "id": 1, "name": "Redirection Rule", "Object": { "frequency": 1, "trigger": 1 }, "Object": { "http": "Redirect Url", "response": 301 } } I need to use this structure to populate a jstree . I just need to use the "id" fields and "name", how do I set jstree to use "name" instead of "text" as a node name ? 回答1: Either: 1) use the jQuery dataFilter option (this means defining a

问题 Greetings, I am using jsTree to generatate my hierarchical data.

问题 I am not talking about $("#demo1").jstree("rename",node) which makes the node editable for the user. I am talking about the name being changed within the code. For example my nodes are all prefixed with a 2 digit number "[01]" so before I call $("#demo1").jstree("rename",node) I want to strip out the prefix, and put it back in once the user has finished editing. I have tried selecting "#nodeid a" but inside the hyperlink there is an ins tag and this gets replaced if i replace the URL contents
