extjs4.2

Hiii all, I am using Extjs 4.2 data grid and i have a requirement to convert my 'store' into json array and send that to server side(i.e java). This is my model. Ext.define('Writer.Document',{ extend: 'Ext.data.Model', fields: ['id', 'name', 'notes', 'Type', 'date'] }); and my store (which contains list of objects) is var store = Ext.create('Ext.data.Store', { model: 'Writer.Document', autoLoad: true, proxy: { type: 'ajax', url : 'findPatientRecordAction', reader: { type: 'json', successProperty: 'success', root: 'prognosis', messageProperty: 'message' } fields: ['id','name', 'date', 'notes' ,

I am trying to dynamically set fields to a extjs data store so that I could dynamically create a different grid at run time. Case A works for me. But when I use as in Case B , the store's proxy hangs on to the previous model and so the grid rendering is messed up. What is the really the difference between these two? Case A Ext.define('FDG.store.reading.FDGDynamicGridStore', { extend: 'Ext.data.Store' }); var fdgstore = Ext.create('FDG.store.reading.FDGDynamicGridStore', { fields: fields, proxy: { type: 'memory', reader: { type: 'json', totalProperty: 'tc', root: 'Result' } } }); fdgstore

I create a treepanel and I and create store like var store = Ext.create('Ext.data.TreeStore', { autoload: false, proxy: { type: 'ajax', url: 'data.php', reader: { type: 'json', root: 'results' } } }); my server print json look like { "results": [ { id : '1' , text : '1', expanded: true, children :[ { id : '5' , text : '5', leaf:true}, { id : '6' , text : '6', leaf:true} ] }, { id : '2' , text : '2', leaf:true}, { id : '3' , text : '3', leaf:true}, { id : '4' , text : '4', leaf:true}, { id : '7' , text : '7', leaf:true}, { id : '8' , text : '8', leaf:true}, { id : '9' , text : '9', leaf:true},

Whenever a store ( Ext.data.Store ) reads data from the server, it sends paging parameters like &page=1&start=0&limit=25 in a json proxy or [page:1, start:0, limit:25] using a direct proxy. I'd like to disable paging in the store or proxy configuration. I found this workaround, but I'm sure there must be a better method. proxy: { pageParam: undefined, startParam: undefined, limitParam: undefined, ... } Does anyone know how to disable paging properly ? Step store: { pageSize: 0, limit:0, .... } excluding from the request page: __ start: __ limit: ___ Another option is to override the proxy's

All examples that I have found so far explain how to render ExtJS (4.2) MVC application within the "viewport", which in other words means full browser screen, and occupying whole HTML BODY. I would like to render application within the existing HTML page within named DIV, so that I can have HTML design around the application. <div id="appdiv"><!-- application runs here --></div> I've seen some sites with ExtJS 4 examples that use trick to render ExtJS app within the page by using IFRAME. Is it possible to avoid IFRAME? And, if it is, how skeleton of ExtJS 4.2 application shall look like if it

Is there a way to get ExtJS intelliSense in Visual Studio 2012? This combined with the new JavaScript support would make my ExtJS projects much easier to code. Adding reference path to ext-all within your js file will provide support. Specifically, using the ext-all-debug-w-comments provides supporting comments provided by sencha. /// <reference path="../../../ext/ext-all-debug-w-comments.js" /> 来源： https://stackoverflow.com/questions/20155317/visual-studio-2012-extjs-intellisense
