问题 I'd like to create a recursive function to parse json-like data as below. When key is xtype, a new class will be created. In particular, when xtype = gridpanel/treepanel, all the properties have to be its constructor argument, otherwise, properties will be added after class has been created. My recursive function as below, I got an error 'too much recursion' at line 21 in ext-all.js. Please take a look, how am I able to solve this problem? codes in main program: me.recursiveParser(null, data

问题 My target is to change header's font size for one single panel. I tried to read http://docs.sencha.com/extjs/4.2.1/#!/guide/theming, but all what I found was theming the whole applications, theming all-the-panels-in-the-project and overriding config options in "Theme JS Overrides", but no CSS variables overriding for single component. Is there any way to achieve it without fussing with this SASS for whole project? 回答1: Just add a class to the panel, then create a rule to match: new Ext.panel

问题 A rather straightforward question. No answer found anywhere. Using ExtJs 4.2 I have two custom VTypes, and one textfield. I want to change that textfield's vtype when the user clicks a radio button. I know that the text field has already been created so doing: textfield.vtype = 'otherType'; won't do it for me. Neither will: Ext.apply(textField,{vtype:'otherType'}); So the obvious stuff is out. Now I'm toying with destroying and re-creating it, but (if it even works) that seems like overkill.

问题 i have a form in extjs and i need to do some validation tests on it on server side and return a message error but i have no clue how to do this! i need to verify if the new added ip adress already exists i also need to verify if it is actually a valid adress (i have a c# function that can do this) if these conditions are ok it can be added. if not, i'd like to show an error message to the user saying what is the problem now when i call my save button submit,i do these tests on my c# before i

问题 I am trying to use Zend Frame work and Ext-Js4 together. But I don't know how to setup file and folder structure correctly.

Thank you.

问题 I am having one grid containing all project details. This grid has its own controller, models, stores. When I double click on the grid it passes the id to my server side. Based on the id passed I execute some query to my database and then returned the data back to client in JSON format. And based on successful response I show another window, which contains all the data returned back from server to client. But the main problem is that the window popup doesn't contain the updated data. Means

问题 In my ExtJS Applications I have 3 components, an Ext.tree.Panel , and Ext.grid.Panel and an Ext.Img . I want them to have the same layout as the Feed Viewer example here: http://dev.sencha.com/deploy/ext-4.0.0/examples/feed-viewer/feed-viewer.html I have been trying to look at the code but I am still having trouble getting my components to look like that (One component on the left, and two on the right one on top of the other). Can anyone explain how I can do this using 'Border' layout?
