For a while ago my colleague gave me a nice tip of getting the right absolute url regardless sharepoint zone in Alternate Access Mappings. I want to share it, because it is brilliant: var url = SPUtility.AlternateServerUrlFromHttpRequestUrl(new Uri(value)).AbsoluteUri;

If you think that “Go to corner” -> Settings -> Power -> Shut down are three steps to much if you just want to shutdown your Windows 8 machine, than do as I did: create a shortcut on you desktop and a tile on your start screen. Create a shortcut as usual: Write in the location field: shutdown /s /t 0 Name it something, why not “shutdown”? Change the default icon: There it is.

I found a great post about using sharepoint tooltips on Andrey Markeev’s (@amarkeev, omlin) blog: JavaScript ToolTip’ы для SharePoint. He describes how he found the standard sharepoint tooltips and how they can be reused. The best part of it his “research”. Andrey’s conclusion is to create an own, simplified javascript class which enables “sharepoint” tooltips. I modified it somewhat. I think there is no need to instantiate a TooltipManager… var Takana = window.

For three months ago I added Chuvash localization of moment.js. For 16 days ago moment.js 1.7.0 was officially released which included the Chuvash translation. Wait a sec… What is moment.js? moment.js is the best datetime tool for javascript. It supports many languages (now even Chuvash) for displaying date and time. Another very handy functionality is showing relative time which has a simple interface: fromNow(). Here is a simple example from a web browser console:

The official Wikipedia mobile app is now translated into Chuvash language and available to use: What does Chuvash mean? I am Chuvash. Chuvash is the name of an ethnicity which counts up to 2 milions peoply (mostly in Russia). Chuvashes talk the Chuvash language which is also an official language in Chuvash Republic (besides Russian). Chuvash language is a Turkic language and has a status “Vulnerable” in the UNESCO list of languages in danger.

Javascript has become popular among many SharePoint developers thanks to easy and fast jQuery, CSOM, SPServices and many other javascript libraries. That can make solutions modern and fast. On the other hand developers should be aware of more things (some of them at Bamboo Team Blog). One of those is scoping of javascript webparts. The problem a developer has to consider: what happens if a user creates two or more instances of the same beautiful webpart on the page?

An interesting question came on SharePoint StackExchange: How to retrieve the guid of the last uploaded file. It is only possible in CSOM as far as I know. But if we simplify the task, how to get the id of the last item, the we can compare three ways of getting them: SPServices, jQuery + listdata.svc and CSOM. SPServices The most easiest way, but not available in async: $().SPServices.SPGetLastItemId({ listName: "Documents" }); listdata.

I saw an interesting question on sharepoint.stackexchange: How to access a Web application/Farm level property bag via jQuery/Javascript/ClientContext. Some time ago I tested a custom http handler, so I wanted to try a custom httphandler for this as well. It worked. Here more details: Just deploy sp-lend-id.tupsam from the solution. If you don’t have any properties in your web application, just add some: asnp microsoft.sharepoint.powershell $app = get-spwebapplication http://dev $app.Properties.Add("Santa", "Claus") $app.

It is not a rocket science to pass objects from child window (popup) to main window. The problem I encountered today was IE and passing complex objects. So it is just an IE issue as far as I know. The problem occurs when you pass some object (not a simple String or Number) to main window: window.opener.takeAnObjectFromChild = { title: "Should even be available when I close the child" }; and you then close the child window, next time the main window tries to access the passed object:

Many words have been said about the importance of performance when working with javascript files. Here I want to summarize what developers can do to increase the performance related to javascript. I found many tips on blogs. Here comes my aggregated list of actions one can do to speed up sharepoint (and not only) sites with focus on javascript: 1. Load only sharepoint stuff you need Use prefetch option to only load sharepoint javascript files that needed.
