Ext.data.JsonStore继承于Ext.data.Store.使得从远程JSON数据创建stores更为方便的简单辅助类. JsonStore合成了Ext.data.HttpProxy与Ext.data.JsonReader两者.假设你须要其它类型的proxy或reader组合,那么你要创建以Ext.data.Store为基类的配置. 代码实例: var store = new Ext.data.JsonStore({ id:'id', url: 'get-images.php', r
多条件查询页面的参数都是动态的,并且我们通常还会有默认加载页面.此时,动态添加参数非常重要,其中baseparam是解决问题的关键. @ 将查询条件定义为一个全局变量 var param_01 = ""; var param_02 = ""; @ Ext.data.Store 默认加载时给param_01和param_02赋值,也可以直接在params直接给定量 var store = new Ext.data.Store({ autoLoad :{params :
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
A Model represents some object that your application manages. For example, one might define a Model for Users, Products, Cars, or any other real-world object that we want to model in the system. Models are registered via the model manager, and are us
对于Ext.data.Store 一直不是很了解,不知道他到底是干嘛的有哪些用处,在实际开发中也由于不了解也走了不少弯路, store是一个为Ext器件提供record对象的存储容器,行为和属性都很象数据表. 由于刚学不是太懂,都是比葫芦画瓢,东搬西畴的去完成功能.程序思路都是自己想象的,对于rest方式的增删改查全是采用另外一种方式去实现的,最后研究发现其实,store都 已经有了这些函数,根本不用自己去实现.下面看下以前所写的代码:这是model,store ,gridpanel var s
var storeCpye = new Ext.data.GroupingStore({ proxy : new Ext.data.HttpProxy({ url : 'cxgl_cpye.app?dateTime=' + new Date().getTime() + '&subTranCode=list' }), reader : new Ext.data.JsonReader({ root : 'hstamcx', totalProperty : "results", fi
