问题描述

嘿伙计们,



我正在建立一个带网格的EXT JS项目。它的商店定义如下:



 createStore: function ( ){
var me = this ;
me.createDataModel();
var store = Ext.create( Ext.data.Store,{
model: tescoModel
id: tescoStore
autoLoad: true
remoteSort: true
pageSize: 20
proxy:{
type: ajax
url: http://www.techfortesco.com/groceryapi_b1/restservice.aspx
limitParam: undefined
startParam: undefined
simpleSortMode: true
pageParam: undefined
noCache: false
actionMethods:{
method: POST
},
reader:{
type: json
root: Products
totalProperty: TotalProductCount
}
}
});





但是这并没有返回任何g,它甚至不会连接到http://www.techfortesco.com ....

我相信extjs只允许连接到内部链接(例如/ techfortesco)。



extjs可以通过外部链接创建商店吗?我做错了吗?



谢谢

解决方案

您需要将代理类型用作'jsonp'

 createStore: function (){
var me = this ;
me.createDataModel();
var store = Ext.create( Ext.data.Store,{
model: tescoModel
id: tescoStore
autoLoad: true
remoteSort: true
pageSize: 20
proxy:{
type: jsonp
url: http://www.techfortesco.com/groceryapi_b1/restservice.aspx
limitParam: undefined
startParam: undefined
simpleSortMode: true
pageParam: undefined
noCache: false
actionMethods:{
method: POST
},
reader:{
type: json
root: Products
totalProperty: TotalProductCount
}
}
});


尝试EXTJS的Loader功能 -



装载机:{
url:'YourSourceUrl',
渲染器:'组件',
autoLoad :true
}







autoload:true,将在初始加载时自动加载数据。


Hey guys,

I'm building an EXT JS project with a grid. Its store is defined with the following:

createStore     :  function() {
       var me = this;
       me.createDataModel();
       var store = Ext.create("Ext.data.Store", {
           model       :  "tescoModel",
           id          :  "tescoStore",
           autoLoad    :  true,
           remoteSort  :  true,
           pageSize    :  20,
           proxy       :  {
               type            : "ajax",
               url             : "http://www.techfortesco.com/groceryapi_b1/restservice.aspx",
               limitParam      : undefined,
               startParam      : undefined,
               simpleSortMode  : true,
               pageParam       : undefined,
               noCache         : false,
               actionMethods   : {
                   method  : "POST"
               },
               reader           : {
                   type            : "json",
                   root            : "Products",
                   totalProperty   : "TotalProductCount"
               }
          }
       });



This however is not returning anything at all, it won't even make a connection to http://www.techfortesco.com....
I believe that extjs only allows to make connections to internal links (e.g. /techfortesco).

Is it possible for extjs to create a store from an external link? Am I doing something wrong?

Thanks

You need to use Proxy Type as 'jsonp'

createStore     :  function() {
       var me = this;
       me.createDataModel();
       var store = Ext.create("Ext.data.Store", {
           model       :  "tescoModel",
           id          :  "tescoStore",
           autoLoad    :  true,
           remoteSort  :  true,
           pageSize    :  20,
           proxy       :  {
               type            : "jsonp",
               url             : "http://www.techfortesco.com/groceryapi_b1/restservice.aspx",
               limitParam      : undefined,
               startParam      : undefined,
               simpleSortMode  : true,
               pageParam       : undefined,
               noCache         : false,
               actionMethods   : {
                   method  : "POST"
               },
               reader           : {
                   type            : "json",
                   root            : "Products",
                   totalProperty   : "TotalProductCount"
               }
          }
       });


Try Loader feature of EXTJS -

loader: {
	    url: 'YourSourceUrl',
            renderer: 'component',
            autoLoad: true
	}




autoload: true, will load data automatically on initial loading.
