硒的getText没有工作，HTML没有包含文本

Question

试图捕捉的WebElement文本有以下两种方法的任何属性，但都返回空字符串

// Method 1 

d.findElement(By.id("deliveryDate")).getTex(); 

// Method 2 

WebElement deliveryDate = d.findElement(By.id("deliveryDate")); 

System.out.println((String) js.executeScript("return arguments[0].innerText;", deliveryDate)); 

要捕获“THU 17年2月2日”
