问题 Developing Worklight 6.0 applications with Dojo 1.9, we're encountering some page navigation problems on Galaxy SII, SIII, Note devices with running Android v4.1.2 (very common). We see these issues were resolved by Dojo patch #17164. This patch is not included in Worklight's default Dojo build. We tried to include it by placing the files in the project's dojox\mobile folder but with no effect - we guess it is being overwritten by unpatched classes during build. Is there any other way to

问题 I have a DataGrid that has items in it. When you right-click on one of the rows, a Dojo Context Menu is displayed with the option to delete that row.

BUT, if you first right click on a row, and then click the Cancel menu option (which does nothing) or if you left-click somewhere else on the page (which hides the Context Menu) and the go to right click on a blank area of the DataGrid, the Context

REST vs. RPC in PHP [closed]

阅读更多关于 REST vs. RPC in PHP [closed]

I'm building my own Ajax website, and I'm contemplating between REST and RPC. If my server supported Servlets I'd just install persevere and end the problem, but my server doesn't support Servlets. RPC is simpler to code (IMO) and can be written in PHP easily. All I need is a database query executer. I'm using the Dojo Toolkit and JSON. Why should I choose REST over RPC or RPC over REST? back2dos Uhm ... to put it simple, both are very abstract models ... so abstract, they naturally occur everywhere... REST is the idea of having resources addressed with a global identifier (the URI in the case

问题 I would like to use Dojo Toolkit with Meteor. I first copy the whole Dojo Toolkit tree in /public Then, I include it on the client side with: <script src="/dojo/dojo.js" data-dojo-config="async: true"></script>` Everything works fine, except Meteor is actually monitoring every single file in /public for changes, so that it can restart the server. This is actually causing a very long delay during the first request on localhost:3000 . Is there a way of preventing Meteor from watching files from
