In SharePoint, the ECB (Edit Control Block) menu provides a context-sensitive menu that offers various actions for list items or documents. Accessing the context information from the ECB menu items using JavaScript can be quite useful, especially when developing custom solutions or enhancing user interactions. In this article, we will explore how to retrieve context information using JavaScript, specifically leveraging the Client Object Model (CAMOpt).
Understanding the Problem
To put it simply, you want to obtain context information about list items or documents when users interact with the ECB menu in SharePoint. This context information can include item IDs, titles, and other metadata that you can utilize in your scripts to perform specific actions or to manipulate the item in question.
Example Scenario
Suppose you have a SharePoint document library, and when users right-click on a document, they see a menu with various options (like "Edit," "Delete," "View Details," etc.). You want to implement a custom action that retrieves the document's ID and title when the user selects your custom menu item.
Original Code Snippet
Here’s a basic structure for accessing the context information:
(function() {
var context = SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('YourListTitle');
// Assuming 'itemId' is obtained from the ECB menu context
var itemId = /* logic to get the item ID */;
var listItem = list.getItemById(itemId);
context.load(listItem);
context.executeQueryAsync(
function() {
var itemTitle = listItem.get_item('Title');
alert('Item Title: ' + itemTitle);
},
function(sender, args) {
console.error('Error: ' + args.get_message());
}
);
})();
Analysis and Clarification
Fetching Item ID
To effectively retrieve the context item ID when interacting with the ECB menu, you need to implement the beforeShow or beforeMenu event. You can attach an event handler that captures the ID of the clicked item:
SP.SOD.executeFunc('sp.js', 'SP.ClientContext', function() {
var ctx = SP.ClientContext.get_current();
var itemId = /* Logic to obtain item ID from ECB */;
// Call your function to get context information
getItemContext(itemId);
});
Custom Menu Item
Creating a custom menu item in the ECB allows users to select your action directly. You can use the SP.Web.UserCustomActions feature in SharePoint to add your custom menu item, which triggers your JavaScript function to fetch the context information.
Example: Retrieving and Using Context Information
Once you have access to the item ID, you can easily retrieve other metadata fields as needed. Here is an extended example that retrieves more than just the title:
function getItemContext(itemId) {
var context = SP.ClientContext.get_current();
var web = context.get_web();
var list = web.get_lists().getByTitle('YourListTitle');
var listItem = list.getItemById(itemId);
context.load(listItem);
context.executeQueryAsync(
function() {
var itemTitle = listItem.get_item('Title');
var itemCreated = listItem.get_item('Created');
alert('Item Title: ' + itemTitle + '\nCreated on: ' + itemCreated);
},
function(sender, args) {
console.error('Error: ' + args.get_message());
}
);
}
