The Tree Panel Component is one of the most versatile Components in Ext JS and is an excellent tool for displaying heirarchical data in an application. Tree Panel extends from the same class as Grid Panel, so all of the benefits of Grid Panels - feat…

Using Events The Components and Classes of Ext JS fire a broad range of events at various points in their lifecycle. Events allow your code to react to changes around your application. They are a key concept within Ext JS. 在ExtJS组件和类的生命周期中,会触发许多类型的事件…

参考 :http://blog.csdn.net/zhangxin09/article/details/6914882 An Ext JS application's UI is made up of one or many widgets called Components. All Components are subclasses of theExt.Component class which allows them to participate in automated lifecycl…

extjs中常常会用到renderTo或applyTo配置选项.这里,我就比較下两者的差别与使用方法.1.renderTo与render方法相应2.applyTo与applyToMarkup方法相应 一.applyTo的使用:1.applyTo所指向的el元素必需要有父节点.2.applyTo所指向的el元素实际上是充当了对象要渲染的模板,对象是渲染在其父节点内.即对象实例化后所产生的html代码是插入在el元素的父节点内,而el元素本身将仅仅作为模板,并不作为真正的在其位置上的元素,既然作为模…

Fields are used to define what a Model is. They aren't instantiated directly - instead, when we create a class that extendsExt.data.Model, it will automatically create a Field instance for each field configured in a Model. For example, we might set u…

This is a static class containing the system-supplied data types which may be given to a Field. Types是一个静态类,包含将用在Field的,系统提供的数据类型. The properties in this class are used as type indicators in the Field class, so to test whether a Field is of a certain…

Readers are used to interpret data to be loaded into a Model instance or a Store - often in response to an AJAX request. In general there is usually no need to create a Reader instance directly, since a Reader is almost always used together with aPro…

The Store class encapsulates a client side cache of Model objects. Stores load data via a Proxy, and also provide functions for sorting, filtering and querying the model instances contained within it. Store类封装了Model对象在客户端的缓存.store通过proxy加载数据,并且提供排序.过…

Proxies are used by Stores to handle the loading and saving of Model data. Usually developers will not need to create or interact with proxies directly. proxy被Store使用以实现加载和保存model数据.通常,开发者不需要直接创建代理或代理交互. Types of Proxy   代理的类型 There are two main type…
