Fetching data from SharePoint List ithout using CAML query - sharepoint

Question

Can you help me in this script? I am trying to pull data from list 'faq' and get an alert of output but without using CAML query. But i am not getting the output. Please help.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<div id="divListItems"></div>
<script>
$(function () {
ExecuteOrDelayUntilScriptLoaded(addListItems, "sp.js");
});
function addListItems() {
var clientContext = new SP.ClientContext();
var oList = clientContext.get_web().get_lists().getByTitle('faq');
var itemCreateInfo = new SP.ListItemCreationInformation();
this.oListItem = oList.getItem(itemCreateInfo);
clientContext.load(oListItem);
clientContext.executeQueryAsync(
Function.createDelegate(this, this.onQuerySucceeded),
Function.createDelegate(this, this.onQueryFailed)
);
}
function onQuerySucceeded() {
alert('Item created: ' + oListItem.get_item('Title'));
}
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() +
'\n' + args.get_stackTrace());
}
</script>
Please let me know if more details are required.

The best way to fetch SharePoint list item using REST API code is below.
ExecuteOrDelayUntilScriptLoaded(initializePage, "sp.js");
function initializePage() {
var siteURL;
var itemsArray = [];
// This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
$(document).ready(function() {
var scriptbase = _spPageContextInfo.webServerRelativeUrl + "/_layouts/15/";
GetSampleListItems();
});
//Retrieve list items from sharepoint using API
function GetSampleListItems() {
siteURL = _spPageContextInfo.siteAbsoluteUrl;
console.log("from top nav - " + siteURL);
var apiPath = siteURL + "/_api/lists/getbytitle(''samplelist'')/items";
$.ajax({
url: apiPath,
headers: {
Accept: "application/json;odata=verbose"
},
async: false,
success: function(data) {
var items; // Data will have user object
var results;
if (data != null) {
items = data.d;
if (items != null) {
results = items.results
for (var i = 0; i < results.length; i++) {
itemsArray.push({
"Title": results[i].Title
});
}
}
}
},
eror: function(data) {
console.log("An error occurred. Please try again.");
}
});
}
}
With out REST API please find the below code.
var siteUrl = 'SiteCollection';//HEre you need to give your site collection URL
function retrieveAllListItems() {
var clientContext = new SP.ClientContext(siteUrl);//Will return current context
var oWebsite = clientContext.get_web();//Curent site
this.collList = oWebsite.get_lists();//Liist
clientContext.load(collList);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
}
//
function onQuerySucceeded() {
var listInfo = '';
//Below is the iteration for item
var listEnumerator = collList.getEnumerator();
while (listEnumerator.moveNext()) {
var oList = listEnumerator.get_current();
listInfo += 'Title: ' + oList.get_title() + ' Created: ' + oList.get_created().toString() + '\n';
}
alert(listInfo);
}
function onQueryFailed(sender, args)
//this will fire when you will any failure in your code..means in your Success method..
}
