请尝试以下代码。希望对你有帮助。我最后测试了一下，效果很好。

  JavascriptExecutor executor = (JavascriptExecutor) driver;
        String data = String.valueOf(executor.executeScript(
                "var styledata = document.getElementById('modalLayer').getAttribute('style');" + "return styledata;"));

        System.out.println(data);
