Hi,
Create a simple web part page in your SharePoint site. Open this page in the SharePoint Designer.  Look for this code in the page: 
<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">Now copy following code after it:<script type="text/ecmascript" language="ecmascript">
var targetWeb;
function runCode() {
// Specify a client context using the server-relative URL of the sub web, load the sub web, and call the ExecuteQueryAsync method.
var clientContext = new SP.ClientContext('/MySubWeb');
targetWeb = clientContext.get_web();
clientContext.load(targetWeb);
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
function onQuerySucceeded() {
// On success, use get_ property assessor methods to return the value of the Title, ID, Language, uiVersion, Description, and Created properties of the SP.Web object.
var message = "Web retrieved:";
message += "\n Title: " + targetWeb.get_title();
message += "\n ID: " + targetWeb.get_id();
message += "\n Language: " + targetWeb.get_language();
message += "\n UI Version: " + targetWeb.get_uiVersion();
message += "\n Description: " + targetWeb.get_description();
message += "\n Created: " + targetWeb.get_created();
alert(message);
function onQueryFailed(sender, args) {
alert('Request failed. \nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
</script>
<input id="Button1" type="button" value="Run Code" onclick="runCode()" />See this for more information:https://msdn.microsoft.com/en-us/library/office/ff410960(v=office.14).aspx
