They seem to be consistent in Firefox and Chrome. So, on to other possible solutions. Testing nested row styles that can interfere. Tests of two interdependent Ember properties, one of which is a computed property. Note that the circularity is defined on only one side -- I don't know that Ember makes it possible to define two computed properties that each depend on the other correctly without infinite loops in the getter.

It seems like it should be possible for Ember to prevent infinite loops in getters: only allow a get of a given property once in a chain before returning the previous value or undefined. Not sure whether this would result in unexpected behavior in some situations. Shows that dependency injection doesn't happen when using Ember. Chris Sullins Seattle, WA.

So my problem is that when i drag and drop a parent folder the confirmation message appears and if i click no the movement didn't stop,that's mean the folder will move under new folder.

It uses jQuery's event system, so binding callbacks on various events in the tree is familiar and easy.

In the standard syntax no fields are required - pass only what you need. Keep in mind you will be able to access any additional properties you specify - jsTree won't touch them and you will be able to use them later on using the original property on each node.

To change the icon of the node use the icon property. You can use boolean false to make jsTree render the node with no icon. You can set the state on a node using the state property. Use any combination of the following: openedselecteddisabled. When using AJAX set children to boolean true and jsTree will render the node as closed and make an additional request for that node when the user opens it. Any nested children should either be objects following the same format, or plain strings in which case the string is used for the node's text and everything else is autogenerated.

To indicate a node should be a root node set its parent property to " ". This should be used mainly when you render the whole tree at once and is useful when data is stored in a database using adjacency.

The expected format is an array of nodes, where each node should be an object as described above or a simple string in which case the string is used for the node's text property and everything else is autogenerated. Any nested nodes are supplied in the same manner in the children property of their parent. The format remains the same as the above, the only difference is that the JSON is not inside the config object, but returned from the server.

In addition to the standard jQuery ajax options here you can supply functions for data and urlthe functions will be run in the current instance's scope and a param will be passed indicating which node is being loaded, the return value of those functions will be used as URL and data respectively. You can supply a function too. That function will receive two arguments - the node being loaded and a callback function to call with the children for that node once you are ready.

What is jsTree? Populating the tree using JSON.The dnd plugin enables drag'n'drop support for jstree, also using foreign nodes and drop targets. The special key used to make a drag copy instead of move "ctrl""shift""alt""meta". The number of milliseconds to wait before checking if a move is valid upon hovering a node while dragging.

The number of milliseconds to wait before opening a hovered if it has children while dragging. This means that the user has to stop over the node for half a second in order to trigger the open operation. Keep in mind that a low value in combination with async data could mean a lot of unneeded traffic, so is quite reasonable. A string jQuery selector or false.

Default is ". A jquery selector matching all drop targets you can also use the commain the string to specify multiple valid targets. If set to false drop targets are disabled.

Return false to mark the move as invalid, otherwise return true. The data parameter is as follows:. A jquery selector matching all foreign nodes that can be dropped on the tree you can also use the commain the string to specify multiple valid foreign nodes.

If set to false dragging foreign nodes is disabled. A function. Gets executed after a dropping a foreign element on a tree item, you get one parameter, which is as follows:.

Viewed 29k times. So, my question. There are two common jQuery plugins called jsTree. This question is for the one found here: jstree. I also want to blow away a tree I've loaded and replace it with a new tree that consists of just a root node. I get no errors in JS but am not seeing any tree change being rendered. So, very interested in any feedback to this question too since it would be the exact same question I'd ask.

Then I could see my replaced tree. Will post an answer with these details. Active Oldest Votes. Fishcake 8, 5 5 gold badges 34 34 silver badges 67 67 bronze badges.

You might want to include all your code, including a JS fiddle then in case the issue is with how you're changing the data rather than how you're refreshing maybe? Also, to answer the secondary question, destroying is less efficient but not really noticeable time-wise from a user perspective, so if that works for you, you might want to stick to it if this turns out to not be easily resolvable.

You can add a few options when rendering a node using a data-attribute note the quotes :. Unlike the previous simple HTML example, this time the. For now it is important to note that jstree will try to parse any data you specify in the core. As seen in the previous example, if this key is missing jstree will try to parse the inline HTML of the container.

The data you use must be in a specific format, each branch of the tree is represented by an object, which must at least have a text key. The children key can be used to add children to the branch, it should be an array of objects. Keep in mind, you can use a simple string instead of an object if all you need is node with the given text, the above data can be written as:.

Instead of a JS array, you can set core. If you cannot provide proper JSON headers, set core. The ids in the server response make it possible to identify nodes later which we will see in the next few demosbut they are not required. Lazy loading means nodes will be loaded when they are needed.The data JSON can be set up in the config or retrieved from a server also ondemand. Version 1. You may need to pass some attributes to the a node, or set some metadata, or use language versions for the languages plugin :.

Specifies the content to load into the container and convert to a tree. The ajax config object is pretty much the same as the jQuery ajax settings object. You can set the data option to a function, that will be executed in the current tree's scope this will be the tree instance and gets the node about to be open as a paramater or -1 for initial load. Whatever you return in the data function will be sent to the server as data so for example you can send the node's ID.

You can set the url option to a function, that will be executed in the current tree's scope this will be the tree instance and gets the node about to be open as a paramater or -1 for initial load.

The error and success functions if present also fire in the context of the tree, and if you return a value in the success function it will be used to populate the tree - this can be useful if you want to somehow change what the server returned on the client side before it is displayed in the tree for example some.

If this option is set to true if an AJAX returns an empty result, the node that was about to be opened will be converted to a leaf node the open icon will no longer be displayed. If this option is set to true only the visible open nodes parts of the returned JSON are converted to DOM nodes, any hidden parts are saved away and parsed ondemand when a node becomes visible.

This is useful when you have a large nested tree which would result in a heavy DOM. NOTE: If both data and ajax are set the initial tree is rendered from the data string.

When opening a closed node that has no loaded children an AJAX request is made. This can be a DOM node, jQuery node or selector pointing to an element you want loaded.

Use -1 for root nodes. A function to be executed once the node is loaded successfully - used internally. A function to be executed if the node is not loaded due to an error - used internally. Returns a jQuery object. This is the DOM node, jQuery node or selector pointing to the element for which data is parsed.
