To get the current anchor, we can use hash property::

var url = window.location;
var anchor=url.hash; //anchor with the # character
var anchor2=url.hash.substring(1); //anchor without the # character

To pass arguments from a ModalDialog is easy. Provide some buttons and invoke close function:

SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, someValue);

The first argument is result, it is a enumeration with three alternatives: cancel, invalid and OK. The value you pass back to the main window can be a simple string, or a complex javascript object. In this example I’ll create a html element which is hidden (id=“modal-form” class=“s4-die”):

<div id="modal-form" class="s4-die">
   <input type="text" class="todo-text"/><br/>
   <input type="button" value="save"
      onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, {title: 'Johannes', property: $(this).siblings('.todo-text')});"/>
   </div>

Then we get the hidden html element and pass it as options to Modal Dialog, provide a callback (cb).

In my previous post I needed the accound id of the current user for posting new list items. To retrieve the id, we can push this to the client from the code behind, or get the current user using Client Object Model. To provide a more generic way we can write a js function which get the current user. But we must even provide some callback functionality, otherwise we don’t know if the operation was successful or not. Let’s be inspired by success and error properties in $.ajax:

tmplItem() works even without ids. To get the current data:

$(this).tmplItem().data;
```If you want to remove, just invoke the ajax and remove with [$.parents](http://api.jquery.com/parents/):

$(this).parents(“li”).remove();

##### Updating data inside tmplItems

If you want to achieve some fancy dependency tracking, consider [knockout.js](http://knockoutjs.com/). But if you just want to update the data object inside a tmplItem, just change the object and call update:

var t = $(this).tmplItem(); var obj = t.data; obj.Address = “hello avenue”; t.update();

In one of my previous posts I showed how to retrieve data from listdata.svc with jQuery $.getJSON method. Getting data is very simple, listdata.svc provides a powerful restful interface with filtering, expanding and other features. Read the best and short introduction to listdata.svc by Suneet Sharma or a more detailed and technical article about filters, functions and operators by Mike Flasko at Microsoft with short examples here. Now back to listdata.svc in the SharePoint environment. Corey Roth provides a good images and sample results. For REST the “http verbs” are very important: GET, POST, PUT, DELETE.. SharePoint RESTful interface defines these verbs like that:

We can use PublishingPageContent Property to write content to a page:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
 <Module Name="Pages" Url="$Resources:cmscore,List\_Pages\_UrlName;" >
 <File Path="Pages\\Help.aspx" Url="Help.aspx" Type="GhostableInLibrary">
 <Property Name="Title" Value="Contoso Help Page" />
 <Property Name="PublishingPageLayout" Value="~SiteCollection/\_catalogs/masterpage/ContosoPageLayout.aspx, Text page" />
 <Property Name="ContentType" Value="$Resources:cmscore,contenttype\_welcomepage\_name;" />
 <Property Name="PublishingPageContent" Value="hello world"/>
 </File>
 </Module>
</Elements>

The cleanest way to auto-resize a textarea while typing (like wall post on Facebook) is George Papadakis solution. It uses only standard javascript and provides eventlisteners for IE (attachEvent) and other browsers (addEventListener):

window.onload = function () {
  var t = document.getElementsByTagName('textarea')[0];
  var offset = !window.opera ? (t.offsetHeight - t.clientHeight) : (t.offsetHeight
    + parseInt(window.getComputedStyle(t, null)
      .getPropertyValue('border-top-width')));
  var resize = function (t) {
    t.style.height = 'auto';
    t.style.height = (t.scrollHeight + offset) + 'px';
  }
  t.addEventListener && t.addEventListener('input',
    function (event) {
      resize(t);
    });
  t['attachEvent'] && t.attachEvent('onkeyup',
    function () {
      resize(t);
    });
}

Other solutions are jQuery.fn.autoResize, jQuery.autogrow, elastic.

Using asp:UpdatePanel isn’t so easy with jQuery(document).ready() or jQuery(window).load(). The jQuery selectors can’t find elements which are not shown in the beginning. All other elements which are loaded dynamically are difficult to catch. I found a solution in forums.asp.net. A user called germanz creates an jQuery event listener AjaxReady, he uses the ASP.NET built-in PageRequestManager. If there only few usages of it it can be invoked directly from a PageRequestManager instance:

As an alternative to asp:Calendar we can use the fancy jQuery UI Datepicker:

$(document).ready(function () {
	$.datepicker.setDefaults($.datepicker.regional\["sv"\]);
	$("#").datepicker({
		changeMonth: true,
		changeYear: true,
		yearRange: "-120:+0" 
	});
});
```I found this a much simple and best solution for an [birthdate input](http://stackoverflow.com/questions/339956/whats-the-best-ui-for-entering-date-of-birth). We can set [international options](http://stackoverflow.com/questions/1865091/jquery-datepicker-language-problem), [year range](http://stackoverflow.com/questions/269545/jquery-datepicker-years-shown), [year](http://stackoverflow.com/questions/3164898/jquery-ui-datepicker-next-and-previous-year) and [month navigation](http://jqueryui.com/demos/datepicker/dropdown-month-year.html). Other options I have tried are asp:Calendar, ajaxtoolkit:CalendarExtender and DateJs. jQuery UI is the most simple much more than datepicker and works smoothily with SharePoint.

To integrate ASP.NET Ajax Toolkit is not the most straight forward task in SharePoint. If you want to take the risk, “Inspired by Technology” provides the best guide so far.
