Native support for async data loading is added (either JSON or XML); A new “lock()” function is available to block any user interaction with the tree. Customization of various strings used throughout the code (e.g. “New Folder”, “Loading …” ) is now possible – you can now pass your own strings ... There is a new hover_mode setting which forces the tree to change only the hover state and not the focus when using the get_* functions (usually used with keyboard shortcuts)

Then you need to include jsTree: Or you could use the minified version: You may change the path to whatever you like, ..... The object follows the built in JSON structure, so you can specify name (or names if using language versions) for the newly created node, attributes, type of the node, open/closed state, etc

this chapter, we learn how to set up a grid panel using both local and remote data, and in both in XML and JSON formats. We also discuss how to prepare different data types and how to create renderers that will style and format the data to your ... We finish up by learning how to nest layouts and make dynamic changes to the layout components. Chapter 8 discusses the presentation of hierarchical information using the Ext JS Tree support. Using real-world examples of

there are a number of ways to save this information so that it can be passed along through the response cycle to finally be logged. you can write out a server-side cookie. you can generate json objects that get embedded in the page

Extending this example. Inline tree node editing. Ext JS already ships with the ability to edit the node names inside a tree (Ext.tree.TreeEditor). Adding some ajax code to save these edits would be a piece of cake! ..... @jerome: This tutorial really only covers integrating the Ext JS tree, as any other trees might require a different implementation (such as yours). However the concept might be the same. Just instead of outputting json you would output xml

extJs可以接受asp、php、java等服务器端生成的json格式的对象。就java来说，extJs能接受三种方式的json对象，一是servlet中拼接json对象；其次是引用json lib 包；三是DWR方式，绕过Controller（就Spring来说）或servlet，在javascript中直接调用java业务逻辑 层中的 .... ">

1) a node is selected in the tree 2) some processing goes on and 3) the tree is rerendered ( from a totaly new JSON Object). After this rendering i want a special node somwere in the “new” tree marked as selected and also the tree opened to that node. ..... I think it's a good idea to differentiate between active items (that are clicked), selected items (that change whenever keyboard navigation occurs) and hovered items (that only react to the mouse). bogdan says:

Lately I have been playing around with a very nice tree control based on jQuery called jsTree. One of the nice features is that it allows populating the tree through asynchronous calls with JSON data representation

I've managed to change the google api lib from database directly and it worked. But the admin section is still broken in some parts. Ive tried many force refresh and even erase the cache folder but the problem persists Was this ... The jsTree guys moved around all the files in their repo into folders such as "_stable". Existing sites worked fine if they had the files cached under the old path but if it was a new site or the cache was cleared then the tree menu broke

... JavaScript UI libs I have ever had the pleasure to work with. They have a particularly nice tree widget that I've leveraged a few times using Json rendered from rails. This page is the only one I've found that explains how to populate it from rails and it leverages acts_as_nested_set. I found that to be a bit of overkill (and in Japanese or something) so I did an alternate version which uses acts_as_tree instead. Here's hoping this saves someone some time… Enjoy :)

We are looking at using jsTree in a JBoss Seam (JSF/Facelets) web application. The tree is part of a larger form with other fields. In reviewing the code, I don't see a way of getting the tree content (data) after the user makes changes and hits the submit ... Are you loading an XML, or using JSON as data? Rafi B. says: June 27, 2008 at 3:06 pm. @vakata, thanks for the quick reply. I'm really glad I find this plugin of yours, it's amazing. I'd love to get the new version,

This is because in this example the XML tree has language versions and the JSON tree has no language versions. In a real-world scenario I guess this won't be an issue, as usually when you drag & drop between trees they will both have the .... A suggestion – it would be nice to be able to easily change both the expand/collapse icon and the background image for the nodes. While you can change the background image for the node they must be approximately the same size or else

Great ! I'm trying to save the tree in sql db over ajax -> php. The node order is one problem to solve. You have to change the node ids in the jstree with every change in the structure. Would be great if someone got an other solution!

tree now allows for some node sizing (see demo); fixed bug when created nodes did not have the leaf class (by addwin); optimized rtl position and images; fixed changing focus when closing focused node (by Karf); fixed before- callbacks parameters (by Colin) ... I deployed the source to my Weblogic, and accessed it through http://localhost:7001/lilly/javascript/jsTree/examples/. I could see few nodes for HTML tree but nothing for JSON or XML.

jsTree is a javascript based, cross browser tree component. It is packaged as a jQuery plugin. jsTree is absolutely free (licensed same as jQuery – under. ... You may change the path to whatever you like, but it is recommended not to rename jquery.tree.js or jquery.tree.min.js as the filenames are used in path autodetection. If you decide to rename them make sure you set the theme_path config option, so that jsTree succesfully includes your chosen theme (you also MUST set

My function does OK, except that when I test for the duplicate it doesn't find it, because it is testing against the tree2 JSON that exists before the drop. I can't seem to access the version of the tree2 JSON that exists after the drop. ... One other oddity: I am using an ajax call to post tree changes to the server. After the call is complete, I am doing tree2.refresh() to try and show the saved changes. I am getting a “this.open is undefined”, Firefox says around line
