问题 I'm looking for information on how to implement secure pages using ExtJS 4. By secure pages I mean the user will log into our website using Siteminder (SSO) and so we will have the user's identity. Then we would determine what roles the user would have by making a database/LDAP call and only render those views/components that the user has access to. Several questions come to mind: 1.)

问题 I have an http API which (shockingly new technique) reacts on different errors setting different response statuses. The question is - while using Ext.data.Store with some XMLHttpRequest-inside proxy, what is the best way to handle this statuses? As far as I can understand, "load" event does not pass status directly, as well as "exception", and the last one actually doesn't even trigger when 4** status is received. So, as I can see from code xhr instance is hidden from Ext.data.store, so the

问题 i have a sencha touch application that uses a tabpanel, a beta version of this application loads all items of the tabpanel and displays it. with so many items, switching between tabs became slower for optimization my idea is to load items only when a certain panel is activated after showing a loading mask. i was able to make it work on first click but when i switch to the same tab another time it's not being filled or at least items are not being showed. no exceptions are thrown.

问题 I have a webpage with buttons designed in Extjs. When the user clicks 1 of these buttons, a window appears with a textfield and a next button. Clicking the next button will load another window with fieldsets, hiding the first one. The number of fieldsets in the second form is to be adjusted according to the user input in the first window. I am trying to use a for loop for this. The code I am using as follows: var win1, win 2, j; var win1items = new Ext.form.FormPanel({ //snip items: [{ xtype:

问题 I'm using the array-grid extjs example to try and fit a gridpanel into a container window. The problem is on resizing the container window, the gridpanel doesn't automatically fit the new size. As I understand it that's how it's supposed to work. Here's the link to the example: http://www.extjs.com/deploy/dev/examples/grid/array-grid.html What I've done is changed the following.. // Added to gridpanel config layout: 'fit', viewConfig: { forceFit: true } // Window container var gridWindow =
