javascript - How to scroll to a div id in GWT -

-

i have webpage iframe in gwt application running. webpage has <div id="head">. not possible scroll in iframe (intended) webpage has example height of 1000px. @ bottom there button , want when clicks on button (note: button in gwt application) want scroll top.

that means iframe needs force parent window scroll top. tried jsni function this:

    public static native void scrolltotop()  /*-{         $wnd.top.scrollto(0,0);     }-*/;

but didn't work. new idea scroll div id "header". know how accomplish this?

i tried this:

document.getelementbyid('header').scrollintoview();

but seems not work (because should in jsni manner?).

thanks inputs!

it fails because gwt runs in iframe, document references gwt's iframe, , not "html host page". have use $doc in jsni reference document (just $wnd instead of window).

but don't need jsni that; plain old java/gwt do:

document.get().getelementbyid("header").scrollintoview();
