问题 [revised] I'm creating a TreePanel in ExtJs that is loading its children from a JSON file. I'm having trouble adding a click action to the nodes. I'm not sure whether it's added in the script creating the tree, or if its added as a property in the JSON, and if so, what the syntax would be. Any help would be appreciated! Please provide an example if possible. 回答1: Add a listener to the TreePanel: listeners: { click: function(node, event){ console.log(node); } } and use the data in the node.

问题 I'm developing some Extjs 6 applications. I'm using Sench Cmd 6 for creating new application. For every project, It creates a new copy of my lilbrary files. I want to re use the library files rather than duplicate them. | -- library files | -- Project 1 | -- Project 2 | -- etc. How can I do it ? 回答1: You need to create first a workspace . Then any app as you want. Would be something like sencha -sdk "/Sencha/ext-6.0.0" generate workspace "/dev/workspace/" sencha -sdk "/Sencha/ext-6.0.0"

In ExtJs3 I had a tree grid which had a loader to load the tree data, like below: loader: new Ext.tree.TreeLoader({ dataUrl: 'Department/DepartmentTree', nestedRoot: 'Data.items' }) So I am trying to create a treeStore in ExtJs4 like below: var store = Ext.create('Ext.data.TreeStore', { model: 'DepartmentTreeModel', folderSort: true, proxy: { type: 'ajax', url: 'Department/DepartmentTree', reader: { type: 'json', root: 'Data.items' } } }); I get

问题 I would like to have a container with border layout (I need the split bar) with two regions, west and center. The west region contains a treepanel that can expand (because it's a treepanel) and I don't know the number of nodes. The center region is also a container that holds a grid and I don't know the number of rows. So both regions' height is unknown until the page is loaded. I also want the page to be scrollable in case one of the regions are bigger than the page. I managed to do so when

问题 I am trying to reuse a store by altering proxy url (actual endpoint rather than params). Is it possible to override proxy URL for a store instance wih the following syntax: { ...some view config ... store: Ext.create('MyApp.store.MyTasks',{proxy:{url:'task/my.json'}}), } if proxy is already well defined on the Store definition? EDIT : AbstractStore source code sets proxy the following way if (Ext.isString(proxy)) { proxy = { type: proxy }; } SOLUTION : store.getProxy().url = 'task/myMethod
