access a list in a subsite with Javascript

Question

How can i access a list in a subsite?

function Read () {

var caml = "<View><ViewFields><FieldRef Name='Title'/><FieldRef Name='ID'/><RowLimit>2</RowLimit></ViewFields ></View>";

var context = new SP.ClientContext.get_current();
var items = contextManagement.get_web().get_lists().getByTitle("Posts");

var query = new SP.CamlQuery();
query.set_viewXml(caml);
results = items.getItems(query);

context.load(results);

context.executeQueryAsync(Function.createDelegate(this, this.Div_befuellen), Function.createDelegate(this, this.onFailure));

}

This is the code, i all ready use. But how i has to change the code when the list is not on a subsite (Root\SubSite)?

I like to show News on the start page of a site collection but the news list is on a subsite (SharePointServer\News) from the sitecollection.

Thanks for your help Stefan

Instead of using SP.ClientContext.get_current() use

var clientContext = new SP.ClientContext('server realtive url of the web');

Check this documentation for more info.
