问题 I just setup an all basic sencha touch application. Just did sencha generate app *Name* *Directory* . The app is generated without any error, but when I start the server and load the application in Chrome (just updated to the latest version), I get a blue screen with three blinking dots.

问题 My page loads super slow right now. Basically, i want to pre-populate the combo boxes that i have. Right now, it pre-populates each one individually and then selects the default value. This is so slow. The user will have to wait about a minute before the page is fully loaded. I'm grabbing the values to populate the combo boxes from a server. The values to pre-select the combo box value are received in an array through the response variable. How do i speed this whole process up? Code is below:

问题 Can anyone tell me why this bit of code doesn't create an entry into localstorage? myLocalStore.load(); var now = new Date(); var cardId = (now.getTime()).toString() + (this.getRandomInt(0, 100)).toString(); var entry1 = { id: cardId, dateCreated: now, title: 'The Title', narrative: 'the Text' }; var newRecord = new PinYin.model.Default(entry1); myLocalStore.add(newRecord); myLocalStore.sync(); console.log(entry1); The console outputs Object{id: "136575772251069", dateCreated: Fri Apr 12 2013

My controller: Ext.define('STK.controller.SiteSelectController', { extend: 'Ext.app.Controller', stores: ['Inventory', 'Stacker', 'Stackers'], models: ['Inventory', 'Stackers'], views: ['scheduler.Scheduler']

问题 I'm having some problems with combobox for selecting items from database. Since more than 100 items are loaded, I use paging toolbar at bottom of combobox. Now if pages size is set to 5 or 50, the paging toolbar shows page 1 of 20 or 1 of 2 depending on pagesize, but combobox shows all 100 items, and just copy them to next page like page size is not set at all. I tried several thing but nothing seems to make it work. What's wrong? { xtype: 'combobox', queryMode: 'local', valueField: 'id',

问题 So, I've got a pretty simple RESTful jersey webservice, and I'm wanting to call it from my javascript code. I have no problem executing a GET request, but for some reason, when I execute a PUT, I get back a "415 Unsupported Media Type" error. Any idea what I'm doing wrong?
