A Simple AJAX App using SharePoint Web Services

March 14th, 2010

In this era of Web 2.0 web applications, I think it was only a matter of time before I needed to investigate how I could apply AJAX to SharePoint. With a little JavaScript and SharePoint’s web services, you can build fancy apps that can easily be dropped into a document library. And after reading Glen Cooper’s blog post on the subject, I figured it was something definitely worth investigating.

I also took this opportunity to improve a process I have to do all the time: what are the internal column names in a list? To get the list information, I built a simple AJAX app that consumes the Lists.asmx web service. Please keep in mind that this code will have be uploaded into SharePoint in order to work (a document library will work) and will not run from your desktop.

Relative Dates in JavaScript

January 23rd, 2010

I was developing an input form for a search when I came across the need to allow the user to filter items using a date range. I had two input boxes where the user could enter a start and an end date. For some of the most common date ranges, I decided to create links that could be clicked to auto-populate the start/end date textboxes. For example, searching for items that were created last week or last month. Using JavaScript’s Date object, I was able to put together some nice examples.

June 2nd, 2009

After looking at a couple of examples online, most of them require the use of SharePoint Designer to make a field read only (or to hide it). Here is a method to make a field readonly using only Prototype (javascript library) and a Content Editor Web Part

Using Prototype’s Element.insert

June 1st, 2009

Strangely, Prototype’s documentation for Element.insert does not have any examples, so I cooked something up quick:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
        "http://www.w3.org/TR/html4/loose.dtd">
 
<html>
 
<head>
 
<title>Template</title>
 
<script type="text/javascript" src="prototype.js"></script>
<script type="text/javascript">
 
Event.observe(window, 'load', function() {
    // Using Element.insert to insert after, before, top, or bottom
    Element.insert($('para1'), { before: "<p>This is paragraph zero.</p>" });
    Element.insert($('para1'), { after: "<p>This is paragraph two.</p>" });
   
    // notice we have to insert using the content container
    Element.insert($('content'), { top: "<p>This is the first paragraph.</p>" });
    Element.insert($('content'), { bottom: "<p>This is the last paragraph</p>" });
});
 
</script>
 
</head>
 
<body>
 
<div id="content">
    <p id="para1">This is paragraph one.</p>
    <p id="para3">This is paragraph three.</p>
</div>
 
</body>
</html>
