gwt调用iframe的方法和变量

不多说了直接上码：

//调用方法

private native void methodName()/*-{        var childrenIframe = $wnd.document.getElementById("id");        var win = childrenIframe.window || childrenIframe.contentWindow;        win.fatherMethodName();    }-*/;

//调用变量

private native boolean methodName()/*-{        var childrenIframe = $wnd.document.getElementById("id");        var win = childrenIframe.window || childrenIframe.contentWindow;        return win.fieldName;    }-*/;
