问题 I have a dynamically-generated Ext.tree.TreePanel in Ext 3.3.1. It looks like this: -root -fruit -apple -vegetable -carrot I need to make a duplicate/copy of this tree . I understand that the ids will be different and that's fine, but I want the text and the structure to be the same. My current idea is to recursively go through and node-by-node create a new tree. Is there a faster way? NOTE: Someone very helpfully suggested cloneConfig(), but my understanding is that it will not capture a

Finally after struggling with extjs tree panel, tree store and building custom reader to read and convert pentaho data for 2 weeks I have managed to load pentaho data into treepanel of extjs. Now my Tree panel is loading same data infinitely. Treepanel looks as follows : Part of my json data looks as follows : { {name: 'US', candidateCount: 3, children: []}, {name: 'India', candidateCount: 922, children: [ {name: 'Goa', candidateCount:124, children: []}, {name: 'Maharashtra', candidateCount: 43, children: [ {name: 'Pune', candidateCount: 3}, {name: 'Mumbai', candidateCount: 33}, {name:

extjs 4 tree select a specific node by its internal id (not by record index)

问题 I'm trying to sync a dataview (explorer window) with a tree (directory tree). When I click on an element on my dataview, I'd like the same node gets selected on the tree The problem is that using the tree.getSelectionModel().select(index) doesn't allow me to select the node by its internal id (the id I provided in my treestore), but only by the record index... So I just can't sync both views... There would be the solution of the expandPath(), but my treestore is fed by a relational database

Automatically check/uncheck all subtree nodes in extjs tree when certain node gets checked/unckecked

问题 How do I automatically check/uncheck all subtree nodes in an extjs tree when a certain node gets checked/unckecked. I already have my tree with checkboxes. The only thing missing is this check/unckeck behavior. I found this: check child nodes of a tree when a parent is clicked [ExtJS] , but it doesn't work for me because the the extjs API seems to be changed. 回答1: I found a solution: oncheckchange = function(node, checked, options){ node.cascadeBy(function(n){n.set('checked', checked);} ); };
