ExtJs 4.2.1 click the button to bring up the form window

When I was a beginner at ExtJs, I wanted to make a project like this: I used EasyUi to click the button to bring up the Dialog box. There is a Dialog in EasyUi, which is very convenient to use, but now I have moved to ExtJs and found that there is no such framework as Dialog. I found no such control on the Internet, so I searched for the implementation method of the ExtJs Dialog box, now I will post the implementation results. If you have any ideas, I hope to leave a message! Ext. get ("btn_edit "). on ("click", function () {var form = new Ext. formPanel ({// labelAlign: 'top', bodyStyle: 'padding: 5px 5px 0', layout: 'form', items: [{xtype: 'textfield ', name: 'title', anchor: '000000'}, {xtype: 'htmleditor ', border: true, id: 'context', plugins: [Ext. create ('ext. zc. form. htmleditorimag')], height: 400, anchor: '000000'}], buttonAlign: 'center', buttons: [{text: 'save', I Con :'.. /.. /.. /Images/extjs/disk.png ', handler: function () {var text = form. getForm (). findField ('context '). getValue (); alert (text) ;},{ text: 'close', icon :'.. /.. /.. /Images/extjs/cross.png ', handler: function () {win. close (this) ;}}]}); var win = Ext. create ("Ext. window. window ", {title:" edit ", // title draggable: false, icon :'.. /.. /.. /Images/extjs/pencil.png ', height: 600, // height width: 800, // width Layout: "fit", // The window layout type modal: true, // whether the window is modal. The default value is false resizable: false, items: [form]}); win. show () ;}); Description: first, use a button listener to listen to the button action. When you click the button, create a FormPanel first, some basic controls are created in this panel. I will not talk about them here. Then I will create a window and use the Panel I just created as the items of this window, in this way, a form window is created, and then displayed. The above code is win. show (). Note: At the same time, set the window code to modal: true. This is a complete window display!
