Hi All,

In a following post we will see about how to get the documents/Items inside the Folder in SharePoint document library.
Below code is developed in SharePoint hosted apps.In a below Example ,I get the Items from "Shared Documents"(Library Name) and "Folder1" is my folder inside the document Library.

'use strict';
var SPAppWebUrl;
var spHostUrl;

(function () {
    // 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 () {
        spHostUrl = decodeURIComponent(getQueryStringParameter('SPHostUrl'));
        SPAppWebUrl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));

        SP.SOD.executeFunc("sp.js", "SP.ClientContext", function () {
            SP.SOD.executeFunc("sp.runtime.js", "SP.ClientContext", function () {
                $.getScript(spHostUrl + "/_Layouts/15/SP.RequestExecutor.js", function (data) {
                    MainFunction();
                });
            });
        });
    });
    function MainFunction() {
        $('#btnGet').on('click', function () {
            getFolderCount()
        });
    }
    function getFolderCount() {
        var url = SPAppWebUrl + "/_api/SP.AppContextSite(@target)" +
        "/web/getfolderbyserverrelativeurl('/Shared Documents/Folder1')/files?" +
        "@target='" + spHostUrl + "'";
        var executor = new SP.RequestExecutor(SPAppWebUrl);
        executor.executeAsync({
            url: url,
            method: "GET",
            headers: { "Accept": "application/json;odata=verbose" }, // return data format
            success: onQuerySuccess,
            error: onQueryError
        });

        function onQuerySuccess(data) {
            var jsonObject = JSON.parse(data.body);
            var results = jsonObject.d.results;
//count inside the folder
            alert(results.length);
            if (results.length !== null) {
                //Looping Jason data and get the documents
                $.each(results, function (index) {
                    alert(results[index].Name);
                    alert(results[index].ServerRelativeUrl);
                });
            }
        }
        function onQueryError(error) {
            alert("Error: " + error.statusText);
        }
    }
    function getQueryStringParameter(urlParameterKey) {
        var params = document.URL.split('?')[1].split('&');
        var strParams = '';
        for (var i = 0; i < params.length; i = i + 1) {
            var singleParam = params[i].split('=');
            if (singleParam[0] == urlParameterKey)
                return decodeURIComponent(singleParam[1]);
        }
    }
})();


Thanks.
