First, Installation:(The premise is that you have to have Java and Tomcat in your computer's environment, and you don't need to install Ruby in ExtJS6.2.)Download two compressed packages: each one isEXT-6.2.0-GPL (This is the SDK file for ExtJS, which is needed when creating a new project).Senchacmd-6.5.2-windows-64bit (this download is decompression, or no pressure.) Anyway, the last to see is an. exe end of the installation file, directly installed

The first two times I introduced the static tree and the tree that was generated from the data loaded by the database, today, I'm going to put some of the main things that are left of ExtJS tree, and the rest is mainly: event processing of trees, editable trees, and drag-and-drop trees, and finally, a tree that can be loaded asynchronously. event handling of the tree The main events of the tree are: 1, expand node events. 2, Collapse node events. 3

Abstract: This article recorded my reading of Joe's biography of the process of some feelings, as well as personal feel better content. For reference only. "In 1958, IBM missed the opportunity to acquire a fledgling company," the source said. The small company invented a new technology called electrostatic copying. Two years later, Xerox was born, and IBM regretted it. "This is 1984 years. IBM wants to take possession of everything. Apple is seen as the only hope that can compete with it.

Extjs initializes the checkboxgroup value Code. For more information, see. The Code is as follows: Ext. override (Ext. form. CheckboxGroup ,{SetValueForItem: function (val) {// multiple option values are separated by commasVal = "," + val + ","This. items. each (function (item ){If (val. indexOf (item. inputValue)>-1 ){Item. setValue (true );} Else {Item. setValue (false );}});}, ClearValueForItem: function () {// clear all valuesThis. items. ea

Today, I helped my friend solve the problem: how to get the information of the first leaf node of the tree using the ExtJs TreePanel control. The principle is very simple, that is, the sequence traversal of the tree. When the first leaf node is encountered during the traversal process, the work is completed. Results::The Code is as follows: The Code is as follows: Var currentRootNode = null; // the currently selected Root NodeFunction NodeClass (){

This article describes the commonly used and very simple tool bar and menu in desktop program development. However, it is not easy to implement the toolbar and menu in general web development, however, extjs allows us to develop web toolbar and menus using methods similar to desktop program development. The ToolBar is easy to use. The key is to add content to the ToolBar. By default, the ToolBar adds a Button, but you can actually add any component to

The definition of Extjs component shows an instance on the Internet, so I copied it and used it later. Now I want to share it with you, if you are interested, do not miss an example on the Alibaba Cloud website, which contains a copy of the definition of the component for your reference: The Code is as follows: Ext. onReady (function (){Var dtCategory = [['All', 'all category'],['1', 'beverages '],['2', 'conditions'],['3', 'confections '],['4', 'da

You may have seen the drag and drop effects. The implementation method is similar. In the following article, I will introduce how ExtJS is used. The Code is as follows: Hello

other user information, you can construct the object based on the actual situation, as long as it is easy to access. There is a problem here, that is, all objects simplecms may be null here, so you need to call the NS method of ext to name it. This can be added to the loader and the code is as follows: Ext. NS ('Extmvcone');Then run and log on to the system through Firefox firenbug. I logged on to the admin as the system administrator. Finally, all the code in the index View

This article mainly introduces four Ajax asynchronous submission methods commonly used in extJS.

This article describes how to select the last selected node after ExtJS refresh by default, if you need a reload operation, you may need to reload the tree after performing operations on the tree node. However, many businesses need to select the last selected node by default after the tree refreshing. In this way, you must first save the information of the previous selected node, and then expand it layer by layer through the node information after rel
