Just include it in your script or function:

if(-not(Get-PSSnapin | 
   Where { $_.Name -eq "Microsoft.SharePoint.PowerShell"})) { 
   Add-PSSnapin Microsoft.SharePoint.PowerShell}

By the way, I found it in PowerShell for Microsoft SharePoint 2010 Administrators by Niklas Goude and Mattias Karlsson. Powershell for Sharepoint Administrators. UPDATE: I found a better way to check a variable for null: Thomas Maurer. Powershell: check variable for null. It is like in javascript, just put it in the if-statement to test if it exists or not:

There is a question in Stackoverflow and this one, too. There is a fine solution for jQuery. The only thing we need is window.location.search. Say we have http://domain.com?q=hello&a=good#home, then it takes only ?q=hello&a=good, and leaves #home and the main url. Anchors can be retrieved with hash. Here are all properties of window.location: Google Chrome provides a fine function: window.location.getParameter: I like the name of this function. So why not to use it or create this one if a browser doesn’t have it? Well here we go:

There are many ways to reload / refresh a page in javascript. One of them is as in discoveringsharepoint.wordpress.com describes:

window.location.reload()
```Today I found some tools which are shipped with ASP.NET/SharePoint to reload a page. The big advantage of them they are designed to work with SharePoint and take all possible aspects of page life cycle into account. The javascript function to refresh a page is just called, guess..: **RefreshPage** and it resides in init.js:

//init.js: function RefreshPageTo(evt, url, bForceSubmit) {ULSA13:; CoreInvoke(’_RefreshPageTo’, evt, url, bForceSubmit); }

Want to run some javascript code everywhere, but not in a modal dialog. Because errors are occured, or this code is unnecessary i dialogs. Well here is a solution I have found after some experiments:

$(document).ready(function() {
  if (!window.location.href.match(/isdlg=1/i)) {
    onDocumentReadyExceptItIsInDialog();
  }
});

function onDocumentReadyExceptItIsInDialog() {}
```This code checks with Regular Expressions if the url of the parent window contains IsDlg=1, if so nothing happens. In the usual case (not inside a dialog), the javascript code runs. EDIT: after I wrote this I actually found that this is the way SharePoint itself does: [![](https://sharepointkunskap.files.wordpress.com/2012/01/isdlg.png "isdlg")](https://sharepointkunskap.files.wordpress.com/2012/01/isdlg.png) So now I update the previous function to this:

$(document).ready(function() { if (window.location.search.match(/[?&]isdlg=1/i)) { return; } onDocumentReadyExceptItIsInDialog(); });

Well, easy. Short story, huh?

In one of my previous posts I showed a simple example how to retrieve data from a web service and render it with jQuery tmpl. To render this I used an id for a template and the container:

<script id="contactTemplate" type="text/html">
    <div>
        Name: {{= Name }} <br>
        Phone: {{= Phone }}
    </div>
</script>

<div id="contactContainer"></div>

To render we select the template and container with jQuery selectors:

function onSuccess(data) {
	$("#contactTemplate").tmpl(data.d.results).appendTo("#contactContainer");
}

On a page with multiple templates and containers it can be a djungle of different ids you have to track. Johan Leino in his great blog post provides a better and simpler way to organize containers and templates. The solution is to extend jQuery selectors (like :even, :odd and more) and introduce two new: :template and :container. This code comes from Johan Leino:

What is better and where and when… I’ll try to find out.. This post will be updated soon. Take a look at this so far: http://sharepoint.stackexchange.com/questions/23209/sharepoint-2010-javascript-client-object-model-cross-site-collections

sprintf is actually the best javascript implementation of sprintf (string.format). But wait, shouldn’t it be some more .NET-like stuff in SharePoint environment? Indeed there is! (Well, not only in SP, but ASP.NET) String.format(“Hello {0}”, “world”) does exactly the same thing as on server side. Wow, it opens for many opportunities, e.g. in jQuery tmpl: String.format validates arguments, and if all is OK, it invokes another function String._toFormattedString:

function String$_toFormattedString(useLocale, args) {
    var result = '';
    var format = args\[0\];
    for (var i=0;;) {
        var open = format.indexOf('{', i);
        var close = format.indexOf('}', i);
        if ((open < 0) && (close < 0)) {             
            result += format.slice(i);
            break;
        }
        if ((close > 0) && ((close < open) || (open < 0))) {
            if (format.charAt(close + 1) !== '}') {
                throw Error.argument('format', Sys.Res.stringFormatBraceMismatch);
            }
            result += format.slice(i, close + 1);
            i = close + 2;
            continue;
        }
        result += format.slice(i, open);
        i = open + 1;
        if (format.charAt(i) === '{') {
            result += '{';
            i++;
            continue;
        }
        if (close < 0) throw Error.argument('format', Sys.Res.stringFormatBraceMismatch);
        var brace = format.substring(i, close);
        var colonIndex = brace.indexOf(':');
        var argNumber = parseInt((colonIndex < 0)? brace : brace.substring(0, colonIndex), 10) + 1;
        if (isNaN(argNumber)) throw Error.argument('format', Sys.Res.stringFormatInvalid);
        var argFormat = (colonIndex < 0)? '' : brace.substring(colonIndex + 1);
        var arg = args\[argNumber\];
        if (typeof(arg) === "undefined" || arg === null) {
            arg = '';
        }
        if (arg.toFormattedString) {
            result += arg.toFormattedString(argFormat);
        }
        else if (useLocale && arg.localeFormat) {
            result += arg.localeFormat(argFormat);
        }
        else if (arg.format) {
            result += arg.format(argFormat);
        }
        else
            result += arg.toString();
        i = close + 1;
    }
    return result;
}

By the way, take a look at summary part of String.format:

Sure you don’t want to load all the properties of listitems, like ContenTypeId and so on. We cannot avoid __metadata property :), but we can let listdata.svc to send only properties we want. By the way, the best tool for building listdata.svc queries is linqpad. Just write a usual Linq and linqpad converts it to web service url query:   Another great stuff is $count, just add ?$count and you get only the count of items, no other junk.

I think, powershell is the best way to do configurations you have to do once. Adding some links to global (top) navigation is one of them:

asnp microsoft.sharepoint.powershell
$w = get-spweb http://takana
$l = New-Object Microsoft.SharePoint.Navigation.SPNavigationNode("Smells like team spirit", "/pages/teamspirit.aspx")
$w.Navigation.TopNavigationBar.AddAsLast($l)

Feature receiver

The alternative is to create a web scoped feature and provide properties:
