SharePoint 2013 – Read List Items using REST API

December 23, 2014 1 comment

SharePoint 2013 introduced Rich REST endpoints, we can use this to query data asynchronously using jQuery/JavaScript.

Here is a sample code which can be used to read items from a SharePoint list

var siteUrl = window.location.protocol + "//" + + _spPageContextInfo.siteServerRelativeUrl;

	url: siteUrl + "/_api/lists/getbytitle('ListTitle')/Items?$select Title",
	type: "GET",    
	headers: { 
		"accept": "application/json;odata=verbose",
		"X-RequestDigest": jQuery("#__REQUESTDIGEST").val()
	success: function(d) {
		var stringData = JSON.stringify(d);
		var jsonObject = JSON.parse(stringData);
		var results = jsonObject.d.results;
		for(i = 0; i < results.length;i++) {
	error: function() {

We are dynamically forming the site url using various tokens.

First we need to get the SharePoint list, for that we use REST method GetByTitle and pass the list title. Then we are selecting the item Title. You can add more fields by separating with comma.

The result is then converted to JSON object using JSON.Parse method.

Finally a loop is used to iterate through the items.
