Reading ListItems inside folders from Sharepoint list( not library) - rest

Question

How to read sharepoint list items from a specific folders using Javascript/Jquery through JSOM or REST?

Answer 1

Using JSOM or CSOM, you need to specify 'FileDirRef' property in CAML Query, and add 'RecursiveAll' scope:
var camlQuery = new SP.CamlQuery();
camlQuery.set_viewXml(
'<View Scope="RecursiveAll"> " +
"<Query>" +
"<Where>" +
"<Eq>" +
"<FieldRef Name="FileDirRef" />" +
"<Value Type=\"Text\">yourFolderPath</Value>" +
"</Eq>" +
"</Where>" +
"</Query>" +
"</View>');

function GetFolders() {
var oWeb = _spPageContextInfo.webAbsoluteUrl;
var URLC = oWeb + "/_api/web/lists/getByTitle('ListName')/items";
$.ajax({
url: URLC,
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
async: false,
cache: false,
success: function (data) {
$.each(data.d.results, function (index, item) {
$.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/GetFolderByServerRelativeUrl('ListName/ListFolder)/listitemallfields/",
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
async: false,
cache: false,
success: function (data) {
}
});
})
},
error: function (data) { }
});
}

You can use REST API to read list items from a specific folders using getfolderbyserverrelativeurl.
Refer below Code :
var folderRelativeUrl = "Relative_URL_Of_Your_Folder"; //here specify relative URL of your folder (e.g. '/Shared Documents')
getItemFromFolder().then(getItemFromFolderSuccess, getItemFromFolderFailed);
function getItemFromFolder(){
return $.ajax({
url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/getfolderbyserverrelativeurl('" + folderRelativeUrl + "')/files?$expand=ListItemAllFields",
type: "GET",
headers: {
"Accept": "application/json;odata=verbose"
}
});
}
function getItemFromFolderSuccess(data){
// success handler
var response = data.d.results; // This is Response Object from Server
}
function getItemFromFolderFailed(error){
// error handler code
}
