This article mainly introduces 4 kinds of Ajax asynchronous submitting methods commonly used in ExtJS, which can be referred to by friends in the following /**nbsp; nbsp; Code is as follows: * The first type of AJAX submission nbsp; * This approach requires direct use of the Ext Ajax method for submission nbsp; * Using this method, you need to encapsulate the parameters to be passed nbsp; * @return nbsp;

The following is an example: CopyCode The Code is as follows: Extjs can be used to add components flexibly. You can directly add objects in the items array, such as new Ext. Button (...), You can also directly add configuration items. As shown in the preceding example, the parameters in

This chapter briefly introduces the simple application of drag-and-drop and pop-up windows. I. Drag and Drop Drag-and-drop in the Ext component system occupies a very important position, many components are encapsulated in the implementation of the drag-and-drop function, this section mainly discusses the drag-and-drop component structure and examples, focusing on the use of the EXT.DD package to implement the drag-and-drop function, rather than with other components 1.1 Use Range (1) You can dr

By default, Panel, Window, and other components of Extjs contain borders. Normally, it is irrelevant to use them independently, however, when Panel is used as a child component of the Window component, a double border occurs. If the Window component contains two or more panels, then, the border between the Panel and the Panel component will be accumulated, that is, it will become a double border. In fact, the double border does not affect the appearan

Tree panelIt is one of the most versatile components in extjs and is suitable for displaying hierarchical data.Tree panelAndGrid panelInherits from the same base class, so allGrid panelThe benefits of features, extensions, and plug-ins that can be obtained are as follows:Tree panelIt can also be obtained. The features of column, column Width Adjustment, drag and drop, Renderer, sorting, and filtering are similar in the two components. Let's start to

the bottom (because the toolbar that contains the Save button is a Window,window border, Of course it affects the border of the bottom toolbar). So the scheme is not feasible. Abandon it! The second option is to preserve the border of the window component, find a way to remove the panel's border, and, by looking at the ExtJS's help document, you can control the Panel's style by defining the bodystyle. Then set the Bodystyle property to the panel above, Gridpanel:bodystyle: ' border-width:1px

. Let's start with the introduction of the store!Store A model is a data model, while a store is a data container. From the database perspective, the store class encapsulates the cache of record objects of a client, providing data portals for UI components such as gridpanel, tree, And dataview. 4.0 of the store is much simplified and refreshing. It is fixed as a reflection of the surface, however, I think this is the result of proxy, Reader/writer's finer division of duties and model introductio
