问题 Update: Hi, I do not think my question is same as the mentioned question, there are 2 reasons: that question is asking about how to overcome the CORS problem and we all know that from a website, you cannot retrieve data from another website(B) which has different domain unless B has specifically configured its website to allow other to access its data. But in my case, the Cordova/SenCha Touch generated app doesn't have the http protocol when requesting, so it's not the same problem. I want to

问题 I would like to find which event handlers are registered over an object (in my concrete case it's the pagetree in the TYPO3 CMS backend). Is there a method to get all event handlers ? 回答1: You can simply walk through its events property. Most of the members will be just true , but those actually representing attached events will be objects. Type something like: var es = Ext.getCmp('my-tree-id').events; for (var k in es) { if (Ext.isObject(es[k])) { console.log(es[k]); } } If your object is a

问题 Is it possible to remote filter smaller than and bigger than? I know how to handle this in php and mysql but I don't know how to set such a filter in a extjs 4 store. 回答1: Out of the box with 4.1, no. You will need to overwrite the responsible provider proxy for that cause currently only property-value pairs get submitted (responsible function). The other point is that the Ext.util.Filter don't support any comparator for remotesort at all. So you have to implement your own and ensure that the

问题 I'm using HP UFT for functional tests. Because of dynamic id definition of ExtJS, I can't use UFT Recording feature. I've tried many ways for assigning dynamic IDs to staticly. I tried to change id: function() in ext-all-debug.js file. I tried to change Components getId() function in ext-all-debug.js file. I tried override components with afterRender method to change ids aswell. Sometimes I achieved to change id's using component's properties (text, fieldLabel, overflowText, etc.), but for

问题 How can I dynamically set a tab index in ExtJS? I can't see anything in the docs for it, only a config option for it. If I try to do an .apply, it still doesn't work. I know I can probably extend the framework to support this since it is just a DOM element, but I'm sure I'm missing something simpler. Help? 回答1: It seems that in the extjs code for field they do this: this.el.dom.setAttribute('tabIndex', this.tabIndex); 回答2: you can use the set method of the Element class which you can retrieve

问题 I am using Ext.Ajax.request() to make an API call which produces MediaType.MULTIPART_FORM_DATA . This is being handled in the php layer which returns the object in header("Content-Type: application/pdf"); echo $response; The problem is, I am not able to handle the received object in the Ext.Ajax.request() since it always handles only Json objects by default. I tried giving Headers , AcceptType in the request, but it always goes to the failure block. Here is the code: Ext.Ajax

问题 I'm new to ExtJS and am having hard time accommodating a large number of columns in a 600px wide Ext.grid.EditorGridPanel (see example below). Scrolling all grid columns together or something similar to the second grid shown in this example (Ext 4) would do it. var grid = new Ext.grid.EditorGridPanel( this.getGridConfig('', ['a', 'b', 'c', '...', 'x', 'y', 'z'], [ { dataIndex: 'a', header: 'A', editor: new Ext.form.TextField({width: 200, allowEmpty: false}) }, { dataIndex: 'b', header: 'B',

问题 I found a plugin that helps me export ExtJS grid data into MS Excel sheet. http://druckit.wordpress.com/2013/10/26/generate-an-excel-file-from-an-ext-js-4-grid/ all works great except for the error I'm getting before opening the file. Peace of my code: if (Ext.isChrome || Ext.isGecko) { // local download var gridEl = this.getEl(); var el = Ext.DomHelper.append(gridEl, { tag: "a", download: title + "-" + Ext.Date.format(new Date(), 'Y-m-d') + '.xls', href: location }); el.click(); Ext.fly(el)
