得到“清除元素时遇到JavaScript错误驱动程序认为这是因为元素被隐藏”错误

问题描述

我第一次遇到此错误，因为我的Selenium脚本能够识别Username Web元素，但在文本框中输入数据时却遇到此异常。

对于UserName元素，我添加了如下所示的显式等待-

webdriverwait wait = new webdriverwait(getDriver(),120,1000);
logger.info("Finding by ID");
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(strConst)));
logger.info(strConst + " element display -" + element.isdisplayed());
cnf.webeditTxtChange(sUtils.getElementById(loginElms.userName),userName,loginTest,"Username");

我既可以看到日志中显示的记录器信息，又可以看到以下错误信息

错误：

A JavaScript error was encountered clearing the element. The driver assumes this is because the element is hidden,disabled or read-only,and it must not be to clear the element.
