Hello Steve,
Thanks for the Reply
Following code helped me in creating the Subsite successfully in host web
Var hostWebUrl;
Var appWebUrl;
Var context;
Var newSubsite;
function () {
try
hostWebUrl = GetQueryString("SPHostUrl");
appWebUrl = GetQueryString ("SPAppWebUrl");
var layoutsRoot = hostWebUrl +
'/_layouts/15/';
$.getScript(layoutsRoot + "SP.Runtime.js",
function () {
$.getScript(layoutsRoot + "SP.js", CreateSubsite);});
catch(ex)
alert("message" + ex.message);
function GetQueryString (name) {
name = name.replace(/[\[]/,
"\\\[").replace(/[\]]/,
var regex =
new RegExp("[\\?&]"
+ name + "=([^&#]*)"),
results = regex.exec(location.search);
return results ==
null ?
"" : decodeURIComponent(results[1].replace(/\+/g,
// Function to create subsite
function CreateSubsite () {
context = new SP.ClientContext(appWebUrl);
var hostContext =
new SP.AppContextSite(context, hostWebUrl);
var webCreateInfo =
new SP.WebCreationInformation();
//set values
webCreateInfo.set_description("New Subsite Created");
webCreateInfo.set_language(1033);
webCreateInfo.set_title("NewSubSite");
webCreateInfo.set_url("SubsiteURL");
webCreateInfo.set_useSamePermissionsAsParentSite(true);
webCreateInfo.set_webTemplate("STS#0");
 this.web = hostContext.get_web();
newSubsite = this.web.get_webs().add(webCreateInfo);
context.load(newSubsite);
context.executeQueryAsync(
Function.createDelegate(this,successHandler),Function.createDelegate(this,errorHandler));
function successHandler() {
alert("subsite created successfully");
function errorHandler(sender, args) {
alert("Could not complete cross-domain call: " + args.get_message());
