javascript: Alert Me on a Page

By Anatoly Mironov

alertme-001 Recently I needed to add an Alert Me link on Pages. Alert Me is a well known SharePoint functionality for notifying users about changes in list or list items. It is availabe in OOB SharePoint as a command in Ribbon if you go to a list view: alertme-002 When you click on this ribbon command, SharePoint opens a modal dialog and takes you to layouts page: SubNew.aspx. To open a modal dialog and load a page is not a rocket science. So a custom “Alert Me” link is doable. As the first step I copied the html markup from the ribbon and adjusted it a little bit. [sourcecode language=“html”] Alert Me [/sourcecode] Then the javascript code which gets the List ID and Page ID is very simple because this information is there in the magic _spPageContextInfo: [sourcecode language=“javascript”] var takana = window.takana || {}; takana.alertMe = function () { var url = String.format("{0}/{1}/SubNew.aspx?List={2}&ID={3}" , _spPageContextInfo.webAbsoluteUrl , _spPageContextInfo.layoutsUrl , encodeURI(_spPageContextInfo.pageListId) , _spPageContextInfo.pageItemId); OpenPopUpPage(url); } [/sourcecode] This code will open a modal dialog in exactly the same way as the ribbon command in OOB SharePoint and let you subscribe to changes on that page. In this code I use String.format which is available on SharePoint pages and _spPageContextInfo which has existed since SharePoint 2010 and has been extended with more useful information about the current context.

How would I do exactly this but with a custom list instead of the site?
