问题描述

element.getAttribute('value') 在量角器中返回 null，尽管在源代码中存在值的详细信息.

element.getAttribute('value') returns null in Protractor, although in source code the value details are present.

下面是我的代码，

console.log(await this.textArea.getAttribute('value'));

我阅读了有关同一问题的其他帖子，但这些帖子都很旧，没有任何解决方案适合我.我还尝试使用 browser.actions().click(element).sendKeys('input').perform(); 输入输入.考虑可能是 sendKeys() API 问题，但仍然没有运气.

I read other posts around the same issue, but those are old and no solution is working for me. I also tried for entering input with browser.actions().click(element).sendKeys('input').perform(); thinking of it could be sendKeys() API issue but still no luck.

同样的代码element.getAttribute('value')"一直工作到 2021 年 6 月 1 日都很好，突然返回空值，不确定是否有任何代码更改或编译器版本需要更新?

And the same code "element.getAttribute('value')" was working perfectly fine till 1st June 2021 and suddenly returning null value, not sure if there are any code changes or compiler version needs to be updated?
