I have some store, which is formed data. On panel it looks how "fieldName" and text field (in depension from invoked form). For example, on one form is displayed "name document" and field, on another: date of selling and date field. Data is formed dynamicly Here is store: tableTempStore = new Ext.data.JsonStore({ url: objectUrlAddress, baseParams: { 'objectID': objectID }, root: 'Fields', fields: [{ name: 'Type', type: 'int' }, { name: 'Value' }, { name: 'IsRequired', type: 'bool' }, { name: 'Identifier' }, { name: 'Data' }], listeners: { load: function(obj, records) { Ext.each(records,

I am trying to create a floating panel over other pre-created panels, I tried following simple codes, but failed: var testPanel = new Ext.Panel({ id: 'testP', width: 50, height: 100, floating: true, title:'Test' }); testPanel.show(); what else I need to think about? thanks! Following needs to be taken care of when using the floating config: 1) Fixed width - which you've done 2) The position must be set explicitly after render (e.g., myPanel.setPosition(100,100); ). You can also set the underlying Ext.Layer config option instead of just setting floating : true . You can do that in the following

I have a ToolBar with some components (TextFields and Buttons) and I would like to dynamically add a component (TextField, for example) before the other components. I tried tbBar.add(myComponent); without success. Any idea? Stefan Gehrig You can use Ext.container.AbstractContainer.insert : tbBar.insert(0, myComponent); As an additional information, you can use " Ext.container.AbstractContainer.container.items .indexOf" to get an index of a specific item in your container. var index = container.items.indexOf(component); container.insert(index, newComponent); 来源： https://stackoverflow.com

I have a question about best practices with the Module Design Pattern. The code below is an example of the way that some of our Components are written (we use ExtJs but that shouldn't matter too much). We build a lot of our components like this and I know that this doesn't match best practices exactly. Have any thoughts to clean up the code? Ext.ns("TEAM.COMPONENT"); function Foo() { // Private vars var privateNumber=0, myButton, privateInternalObject; var numberField = new Ext.form.NumberField({ label : 'A NumberField!', listeners : { 'change' : function(theTextField, newVal, oldVal) {

In my Ext Js solution I am calling a service which is returning this JSON format {"success":true,"filename":"spreadsheet.xlsx","file":[80,75,3,4,20,0,...(many more)]} How can I make a file download dialog with the filename and the content of the byte array (file) ? UPDATE So I found this bit to start the downlaod var a = window.document.createElement('a'); a.href = window.URL.createObjectURL(new Blob(data.file, { type: 'application/octet-stream' })); a.download = data.filename; // Append anchor to body. document.body.appendChild(a) a.click(); // Remove anchor from body document.body

All the ExtJS documentation and examples I have read suggest calling superclass methods like this: MyApp.MyPanel = Ext.extend(Ext.Panel, { initComponent: function() { // do something MyPanel specific here... MyApp.MyPanel.superclass.initComponent.call(this); } }); I have been using this pattern for quite some time and the main problem is, that when you rename your class then you also have to change all the calls to superclass methods. That's quite inconvenient, often I will forget and then I have to track down strange errors. But reading the source of Ext.extend() I discovered, that instead I
