问题 Say the component doesnt have an ID given to it.

In your javascript code put: console.log(myComponentWhosIdIWantToGet); Explore you object's properties. 回答2: I believe this is what you need: http://docs.sencha.com/extjs/4.2.2/#!/api/Ext.Component-method-getEl Example: //get Dom Element var DomEl = Ext.getCmp(

问题 How to check the style properties in extjs? To set a style to a panel, we can use setBodyStyle . After setting the style, I want to check the value of a particular property. Like, var panel = Ext.getCmp('id'); if(panel.getStyles().fontSize == 24) //for example //do this stuff else //do the other stuff I am using extjs 4.1.1a 回答1: These methods are only available on Ext.dom.Element level.

问题 I'm trying to add Ext4 charting to an existing Ext3 application, using ext-all-sandbox.js. I've got the basics working, but the code below gives axis.processView is not a function . It works fine without the axes defined (but with no axes obviously). It appears that the config objects are being used directly instead of being used to create actual axis instances. Any solutions to get this working? TestGraphPanel = Ext.extend(Ext.Panel, { initComponent: function() { TestGraphPanel.superclass

问题 I have a grid with row-editing enabled. When I add a row and call store.sync(), the server generates certain fields on that record, and returns the full record info in the response. However, ExtJS does not seem to update its copy of the record, except for the id. Is there a way to make it do that, or do I need to write custom code?

问题 I am currently building an mobile application that is based on Sencha Touch 2. At the moment im just trying out some experiments to see what Sencha is capable too. And today I got stuck on a thing that really seems strange - I just wanted to try if I could use the jQuery library for my application and use it's additions. Strangest thing is I can't get any response from when I am making a jquery function. I've included the jquery library and my script in the index.html file in my sencha

问题 Per Sencha documentation, numbercolumn, datecolumn and booleancolumn does not have a renderer event. As logical as this sounds there is an inherent issue with not having a renderer event on these column types. Example of a renderer function in a view controller to modify the background color when the LineNum of the record is in the array of warning line numbers. renderCompanyID: function(value, metaData, record, rowIndex, colIndex, store, view) { if (record.get('LineNum') > 0) { this
