Office 365 – Using jQuery with SharePoint Online

JavaScript, whether you love it or hate it, it’s here to stay. Now, JavaScript does have its quirks and irritations, especially if you’re used to managed code such as VB.Net or C#. However, despite the bad rep a lot of folks have given it, it is one heck of a powerful language.

If you’re like me, you like to get the job done. Sure, sure, it’s fun to dig into the code to see exactly how stuff is done, but that is not really an option when you have a deadline. That is why I choose to use jQuery when I need to liven up a web page or do some web programming magic.

JQuery was first released in 2006 and has since become one of the most popular JavaScript libraries on the web. Microsoft has thrown its weight behind it and now also provides developer support as well as adopting it in their AJAX and ASP.Net MVC frameworks.

So, how do we use all this jQuery goodness in SharePoint Online? That is what I hope to show you in today’s article where we’ll write a fairly simple SharePoint WebPart and add some jQuery logic to it.

Referencing jQuery from SharePoint

Before we can use jQuery in our SharePoint web part we need to find a way to reference the library. There are a few options available to us, of which one is to simply add a reference to the script via a Content Delivery Network (CDN). In the example below we’re referencing the jQuery library via Google’s CDN:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" 

Using a content delivery network like Google’s is a great way to speed up your website as the chances are the user visiting your website has already visited a website that also references a library in the Google CDN and it is already in the users’ cache. To see a list of libraries available via the Google CDN, have a look at the Google Libraries API – Developer’s Guide.

Another option and the one we’ll be using for this example is to create a SharePoint document list to hold all your scripts. Create a new document library in SharePoint by selecting New Document Library from the Site Actions menu.

Creating a new document library in SharePoint

Name the library Scripts and click Create.

Giving a name to a new library

Next, we need to add the jQuery library file to the Scripts SharePoint library. Head over to https://jquery.com/ to download jQuery. Name the file jquery.js and upload it to the Scripts library. One benefit of storing your javascripts in a SharePoint list is that you can reuse it.

The nice thing about jQuery is that it has a whole host of community developed plug-ins, one of which is Hovercard. We’ll use this plugin to show more details about items in a SharePoint list called Books. Download Hovercard and also add it to the Scripts SharePoint library.

Creating the SharePoint WebPart

With the jQuery library and Hovercard plugin file uploaded, let’s create a new Empty SharePoint Project in Visual Studio 2010. Today we will not use the “ADX SharePoint Ribbon” project template because our Ribbon Designer for SharePoint and Office 365 would add a new SharePoint feature already containing ribbon while we need a new empty project.

Creating a new Empty SharePoint Project in Visual Studio 2010

Select a local SharePoint site for debugging and make sure to select Deploy as a sandboxed solution.

Deploying as a sandboxed solution

Next, add a Visual Web Part (Sandboxed) item to your project. If you don’t see the Web Part (Sandboxed) item, you need to install the Visual Studio 2010 SharePoint Power Tools.

Adding a Visual Web Part (Sandboxed) to your project

We won’t add any visual controls to our web part, but we’ll do everything in mark-up. The entire code listing for the Visual Web Part is as follows:

<%@ Assembly Name="$SharePoint.Project.AssemblyFullName$" %>
<%@ Assembly Name="Microsoft.Web.CommandUI, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
    Assembly="Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Register TagPrefix="Utilities" Namespace="Microsoft.SharePoint.Utilities" Assembly="Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Import Namespace="Microsoft.SharePoint" %>
<%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages"
    Assembly="Microsoft.SharePoint, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="jQueryWebPart.ascx.cs"
    Inherits="jQueryAndSP.jQueryWebPart.jQueryWebPart" %>
<script src="../Scripts/jquery.js" type="text/javascript"></script>
<script src="../Scripts/hovercard.js" type="text/javascript"></script>
<div id="books">
<script type="text/javascript">
    ExecuteOrDelayUntilScriptLoaded(LoadList, "sp.js");
    function LoadList() {
        var context = new SP.ClientContext.get_current();
        var web = context.get_web();
        var bookList = web.get_lists().getByTitle('Books');
        var query = SP.CamlQuery.createAllItemsQuery();
        allItems = bookList.getItems(query);
        context.load(allItems, 'Include(Title,Synopsis)');
        context.executeQueryAsync(Function.createDelegate(this, this.ListRetrieved), Function.createDelegate(this, this.RetrievalFailed));
    function ListRetrieved() {  
        var listEnumerator = this.allItems.getEnumerator();
        var count = 1;
        while (listEnumerator.moveNext()) {
            var currentItem = listEnumerator.get_current();
            var id = 2;
            var title = currentItem.get_item('Title');
            var synop = currentItem.get_item('Synopsis');
            $("#books").append('<div id="book-"' + count + ' class="book" title="' + synop + '">' + title + '</div><br/><br/>');
        $('.book').each(function () {
            var synop = $(this).attr("title");
                detailsHTML: "<div><p>" + synop + "</p></div>",
    function RetrievalFailed(sender, args) {
        alert("Could not retrieve list:" + args.get_message());

In the code above we referenced the jQuery and the Hovercard files we’ve added to our Scripts document library earlier. The ExecuteOrDelayUntilScriptLoaded method is a built-in SharePoint method, which will execute the specified function only after, in this case the sp.js javascript file, is loaded. SP.js is a javascript library that gives us access to the SharePoint client object model.

The LoadList function retrieves all items from the Books SharePoint list and the ListRetrieved function loops through all the list items and appends the values, using jQuery, to the books Div.

Finally, we loop through each html element that has a class name containing the word book and add a Hovercard to it with the elements’ title attribute as the Hovercards’ detailsHTML.

Packaging and deploying to Office 365 SharePoint Online

Once everything is tested you can package the SharePoint solution by selecting Package from the Visual Studio Build menu. This will create a .wsp file in your projects’ bin folder. Check your Output window for the full path to the file if you’re not sure.

Packaging the SharePoint solution

Next, log into your Office 365 SharePoint Online account, and click on the Site Actions > Site Settings menu item.

Site Settings

Next, click on the Solutions link under the Galleries heading.

Click on the Solutions link under the Galleries heading.

Click on the Upload Solution button on the Solution tab:

Uploading the solution

Select and upload the .wsp file and click OK. When prompted activate your solution by clicking on the Activate button.

Activate your solution by clicking on the Activate button

Navigate to a SharePoint page, and insert the jQuery web part we’ve just uploaded.

Inserting the jQuery web part we've just uploaded

Once you’re finished editing the page, and the page loads, it will display a list of all the items in the SharePoint Books list. When you hover the mouse cursor over a book title it will display the books’ synopsis:

When you hover the mouse cursor over a book title the books' synopsis is displayed.

    The Books object is a SharePoint List, you need to add the Title and Synopsis columns to this list if it does not already have it.

    Hope this answers your question.

    Hi to all,

    I am using the same proedure created locally sandbox solution and packaging in to the office 365 online.but i am not able to find that in the office 365 which is working in the lical site perfectly….

    Thank you.

  • udaya says:


    I got the answer for my issue that why i am not getting my sandboxes visual web part.
    When i added my visual web part in new project there some “usercontrol.ascx.g.cs” file is missing.
    because of this i am not getting my solution.
    Please any one tell me why its happens and relation of that file with the visual web part.

  • Dmitry Kostochko (Add-in Express Team) says:

    Hi Udaya,

    The ascx.g.cs file is a designer file that is created by Visual Studio. Please have a look at the following pages, this problem is rather common:
    SharePoint Web Part with Custom User Control – ascx.g.cs is cleared
    SharePoint 2010 Visual Web Parts Missing .ascx.g.cs In Visual Studio 2012
    Sand boxed Visual webpart

    So, it seems to be a bug in Visual Studio, you can try to open a new case at the Microsoft Connect web-site.

    sorry for mistake your reply*

  • Uriah Massey says:

    You have deploy jquery library to document library like style library and refer it from there. You can use CDN too if you prefer to do so.

  • Pieter van der Westhuizen says:

    Hi Uriah,

    Yes that is another option, I’ve mentioned in the article.
