A Form Panel is nothing more than a basic Panel with form handling abilities added. Form Panels can be used throughout an Ext application wherever there is a need to collect data from the user. In addition, Form Panels can use any Container Layout, p…

在之前的开发extjs中,用ext.form.panel开发了一个表单,当使用了reset(true)之后,再次使用getRecord()却还是可以得到值,该值为上一次的旧值,查看了api文档,再结合源码来看,发现了其中的错误,其中在form中查看reset()方法,可以看到是这么定义 的, reset: function() { this.form.reset(); }, 可见其中的参数并未传递到真正的reset()方法中,该方法继承自Ext.form.base中查看其中的代码 reset:…

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…

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…

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…
