The example in this topic show how to use JSOM to Get List Item in SharePoint
- You can use Content Editor or Script Editor web part
on your site, put Html and
JSOM (Java Script Object Model) code and that's it. You can perform any action supported by JSOM APIs
How to execute JSOM code in SharePoint?
- Note: This is just a sample, you can go ahead with your
implementation.
- Open your Site. Create a webpart page.
- Put a Content Editor Web part and a Script Editor Web part
on it.
- I have added below Html in Content Editor webpart.
You can replace MainFunction with your actual method name.
<button onclick="MainFunction();"
type="button">Click
me</button>
- And below references in Script Editor Webpart.
You can keep jQuery reference as per your need. ScriptFile.js is a JavaScript
file where you can keep below function i.e. your actual logic.
<script src="https://code.jquery.com/jquery-2.2.4.js"
type="text/javascript"></script>
<script type="text/javascript"
src="/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript"
src="/_layouts/15/sp.js"></script>
<script src="https://MyServer/sites/SiteCollection/style
library/js/ScriptFile.js"></script>
- Once you are done with setting your page, click on the button and your method should
get executed.
- var oListItems, clientContext;
-
- function GetListItem() {
- // You can optionally specify the Site URL here to get
the context
- // If you don't specify the URL, the method will get
the context of the current site
- // var clientContext = new
SP.ClientContext("http://MyServer/sites/SiteCollection");
-
clientContext = new SP.ClientContext();
-
- var oWeb = clientContext.get_web();
-
- // Specify list title here
- var oList = oWeb.get_lists().getByTitle("List Name");
-
- // Get Item using CAML Query
- var camlQuery = new
SP.CamlQuery();
-
- // Get Item using CAML Query
-
camlQuery.set_viewXml('<View><Query><Where><Eq><FieldRef
Name=\'Title\'/>' + '<Value
Type=\'Text\'>New item
value</Value></Eq></Where></Query></View>');
-
oListItems = oList.getItems(camlQuery);
-
- // Load list items to Client Context
- // "Include" will get only "Title"
and "Id" properties, rather than fetching all the properties(This
avoids unnecessary data transfer between client and server)
-
clientContext.load(oListItems, 'Include(Title,
Id, Notes)');
-
- // Execute the query to the server.
-
clientContext.executeQueryAsync(onsuccess, onfailed);
- }
-
- function onsuccess() {
-
- // Get list item count of the items to be displayed
- var itemCount = oListItems.get_count();
-
- for (var i = 0; i
<= itemCount - 1; i++) {
- var oListItem = oListItems.itemAt(i);
-
console.log("Notes: " +
oListItem.get_item('Notes') + " ==== Title: " + oListItem.get_item('Title'));
- }
- }
-
- function onfailed(sender, args) {
-
console.log('Failed' +
args.get_message() + '\n' +
args.get_stackTrace());
- }
