Answer 1

这个错误信息...

org.openqa.selenium.JavascriptException: Page reload detected during async script 
Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:53' 
System info: os.name: 'Windows 8.1', os.arch: 'amd64', os.version: '6.3', java.version: '1.8.0_221' 
Driver info: org.openqa.selenium.ie.InternetExplorerDriver

...暗示 InternetExplorerDriver 无法与 Browsing Context 交互，即 InternetExplorer Browser届会.

关于以下内容的更多详细信息：

Selenium 绑定艺术，即 Protractor / Java / Python / C#.
客户端版本。
InternetExplorerDriver 版本。
相关HTML（如果适用）。

会帮助我们构建一个规范的答案。

但是，如果您使用的是 Protractor as per the documentation in Page reload detected during async script，则此错误意味着：

There was a navigation or reload event while a command was pending on the browser. Usually, this is because a click action or navigation resulted in a page load. Protractor is trying to wait for Angular to become stable, but it's interrupted by the reload.

解决方案

作为解决方案，您可能需要插入一个 browser.wait 条件以确保在继续之前加载已完成。

能否请您提供 a minimal sample to reproduce 问题？您使用的是哪个代码片段运行，错误发生在哪一行？您可以按照以下示例在 Java:

中使用 Selenium webdriver 自动化 IE

import org.openqa.selenium.By;     
import org.openqa.selenium.WebDriver;     
import org.openqa.selenium.ie.InternetExplorerDriver;     
import org.openqa.selenium.WebElement; 

public class new_java_class {              
public static void main(String[] args) {     
  //add the IE web driver path here..     
  System.setProperty("webdriver.ie.driver","your\path\to\IEwebdriver\IEDriverServer.exe");              
       WebDriver browser = new InternetExplorerDriver();     
       //replace the URL of the web page here..     
       browser.get("http://testsite.login/");                     
       WebElement username = browser.findElement(By.name("uname"));      
       username.sendKeys("test_user");                     
       WebElement password = browser.findElement(By.name("psw"));        
       password.sendKeys("abcd@1234");                     
       WebElement btn = browser.findElement(By.name("signIn"));      
       btn.click();                     
}              
}

问题已通过使用 CSS 定位器而不是 AsynScript 在 Web 元素上执行点击操作得到解决。谢谢
