java - 等到文本框 Selenium 中不存在文本

Question

下面是我尝试自动化的场景:

1) Some text is already present in Textbox.
2) Click on Radio button.
3) Processing popup is displayed for few seconds. After popup disappears the textbox 
   becomes blank
4) After textbox is blank then I have to enter different value in text box.

请帮帮我，如何等到文本框值为空。

我正在使用 IE 驱动程序实现自动化。

提前致谢

我会尝试:
整数超时 = 10；//取决于你的需求
WebDriverWait myWait= new WebDriverWait(driver,timeout);
myWait.until(ExpectedCondition.textToBePresentInElementValue(By locator, String text))
-- 空字符串作为文本参数传递
