extjs

问题 I'm using extjs and just trying to solve a simple problem: I have a form with a fixed width. I want to Center this form within a normal Ext.Panel. I'm trying to achieve this the 'css-way' - setting the left and right margin to 'auto'. But this doesn' work, it seems the margins are just ignored. The Code: var curStateForm = new Ext.FormPanel({ title:'test', width:300, bodyStyle:'margin:5px auto 0 auto', items: [edIst, edAdjust, edSumme] }); var testPanel = new Ext.Panel({ width: '100%', frame

问题 I have the simple form: myForm = new Ext.form.FormPanel({ width:'100%', frame:false, items: [ new Ext.form.TextArea({ id:'notes', name: 'notes', hideLabel: true, width:350, height:200 }) ], buttons: [ { text:"Save", click: function (b,e) { alert('x'); } } ] }); However I am having trouble getting the click event of the button to work. Do buttons created the following way have the same functionality of doing Ext.Button? 回答1: You either need a) The handler option (a click shortcut) new Ext

问题 I have to create a universal app from scratch. First the classic app, and at some point in the future, the modern app. I have generated the app using Cmd. I have implemented the basics I need for the classic app, split off everything that can be reused in the modern app and put it into the shared directory. The problem is that now, when I compile with Cmd, I get the error that dependencies are missing (because views are missing in the modern app that I have implemented for classic only, but

This is my grid: onBtnRoutesSearchClick: function(button, e, options){ var me = this; var v_url = 'GetRoutes.jsp?' + Ext.urlEncode({

问题 Here's a demo app: demo Sencha Touch app. The button in the bottom-left corner should show/hide the menu panel on top of the "Location info goes here" bar, however, it works in a strange way. Here's how (IMO) it should work: I click a button A panel appears Here's how it works now: I click a button Nothing happens I resize a window or press F11 (which is resizing too, anyway) A panel appears So, can somebody explain why is this happening and how can I solve my issue? Thx. 回答1: I've found a

问题 I would like to switch views with a button, there is absolutely no examples of it in a MVC context in the sencha documentation although they recommend developers to use their build in MVC architecture. I guess its because Touch 2.0 is rather new. http://docs.sencha.com/touch/2-0/#!/api The video about the list component is also about navigation.View, but since the list component is used, they dont show how to switch views with a button. Video: Intro to List Component This is the code i have

问题 I have a combo-box in which the values are being displayed in a template. Now, I want the width of the template to be more than that of combo-box and hence I am using matchFieldWidth:false as mentioned at the link - ExtJS ComboBox dropdown width wider than input box width? But when I do so, then in the list of values there is no scrollbar displayled due to which the user is able to see only the first two values. The complete list gets displayed as soon as matchFieldWidth:false is removed, but
