C# IWebDriver.GetWindowHandles方法代码示例

        /**
         * Selects the only <code>_blank</code> window. A window open with
         * <code>target='_blank'</code> will have a <code>window.name = null</code>.
         * <p/>
         * <p>This method assumes that there will only be one single
         * <code>_blank</code> window and selects the first one with no name.
         * Therefore if for any reasons there are multiple windows with
         * <code>window.name = null</code> the first found one will be selected.
         * <p/>
         * <p>If none of the windows have <code>window.name = null</code> the last
         * selected one will be re-selected and a {@link SeleniumException} will
         * be thrown.
         *
         * @throws NoSuchWindowException if no window with
         *                               <code>window.name = null</code> is found.
