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…
