If your library is doing this in places where there are no embedded closures/callbacks that might have their own value of this, then this is just a “practice” or “style” or “convention” that they decided to follow in their methods. There is NO programming reason to always do it. In the specific coding example you … Read more
Have a look at the XTemplate constructor API docs. There are lots of good examples there. Quoting: Anything between {[ … ]} is considered code to be executed in the scope of the template. So you should be able to do something like: ‘<img src={[this.getThumbUrl(rawThumbUrl)]} />’,
This is not a question that can be answered by us. You already give a solid overview for your team (which is all that matters): Same rich controls ExtJS Pros more widget components scheduler control ExtJS cons Sencha does not make its source code available on GitHub for pull requests There is no public issue … Read more
Your fiddle already had the start of the answer – to do a second flip on the text. There was an extra , preventing the second rule from being parsed. I’ve updated the fiddle to include the heading elements, and set them to inline-block because inline elements can’t be transformed. .flip-horizontal, .x-grid-cell-inner, .x-column-header-text, .x-panel-header-text { … Read more
I personally think that keeping the files separate during development is invaluable and that during production is when something like this counts. So I modified my deployment script in order to do that above. I have a section that reads: <Target Name=”BeforeDeploy”> <ReadLinesFromFile File=”%(JsFile.Identity)”> <Output TaskParameter=”Lines” ItemName=”JsLines”/> </ReadLinesFromFile> <WriteLinesToFile File=”Scripts\all.js” Lines=”@(JsLines)” Overwrite=”true”/> <Exec Command=”java -jar … Read more
Need to convert it in base64. JS have btoa() function for it. For example: var img = document.createElement(‘img’); img.src=”data:image/jpeg;base64,” + btoa(‘your-binary-data’); document.body.appendChild(img); But i think what your binary data in pastebin is invalid – the jpeg data must be ended on ‘ffd9’. Update: Need to write simple hex to base64 converter: function hexToBase64(str) { return … Read more
Store.getRange() seems to be exactly what you are searching for. It will return you Ext.data.Record[] – array of records. If no arguments is passed, all the records are returned.
Bill, I know this question is pretty much ancient, but I needed a solution and figured I’d post it here for others. I solved the problem myself by attaching the viewDisplay event to my calendar (this event was removed in v2 of FullCalendar, viewRender may be used instead). $(“#calendar”).fullCalendar({ viewDisplay: function (element) { } }); … Read more
Usually so you can keep a reference to this inside a scope in which this refers to something else (like a callback function, for example). Consider this example, in which the click event handler function has a different context to what you may expect (this doesn’t refer to an instance of MyClass): var MyClass = … Read more
Am I supposed to write my web applications with ExtJS like that? One page that should never be refreshed, and everything getting done by AJAX? You don’t have to write your applications like the ExtJS documentation. If you look at the example pages for ExtJS you’ll see a lot of HTML mixed in with Ext … Read more
