javascript - 组织.openqa.selenium.JavascriptException : SyntaxError: '' string literal contains an unescaped line break while using executeScript through Selenium

Question

org.openqa.selenium.JavascriptException: SyntaxError: '' string literal 在通过 Selenium 使用 executeScript 时包含未转义的换行符

executeScript() 以单行 String 为例:

String myText = "80120804076";

但是当我尝试发送多行 String 时，引发了 JavascriptException。

• 代码试验:

  import org.openqa.selenium.By;
  import org.openqa.selenium.JavascriptExecutor;
  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.firefox.FirefoxDriver;
  import org.openqa.selenium.support.ui.ExpectedConditions;
  import org.openqa.selenium.support.ui.WebDriverWait;
  
  public class send_large_text {
  
      static WebDriver driver;
      public static void main(String[] args) {
          System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
          driver = new FirefoxDriver();
          driver.get("https://translate.shell.com/");
          //String myText = "80120804076";
          String myText = "No, there is no way to hide the console window of the chromedriver.exe \n"
              + "in the .NET bindings without modifying the bindings source code. This is seen \n"
              + "as a feature of the bindings, as it makes it very easy to see when your code \n"
              + "hasn\'t correctly cleaned up the resources of the ChromeDriver, since the console window \n"
              + "remains open. In the case of some other languages, if your code does not properly clean up \n"
              + "the instance of ChromeDriver by calling the quit() method on the WebDriver object, \n"
              + "you can end up with a zombie chromedriver.exe process running on your machine.";
          (   (JavascriptExecutor) driver).executeScript("arguments[0].value=\'" + myText + "\';", new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("textarea.form-control#translateText"))));
      }
  }

我经历过相关的讨论:

• Java:
  • Java multiline string
• JavaScript:
  • How do I break a string across more than one line of code in JavaScript?
  • javascript Syntax error : Unterminated string literal
  • Common sources of unterminated string literal
  • unterminated string literal

引用:SyntaxError: unterminated string literal

仍然不知道我哪里出错了。谁能帮帮我？

Answer 1

这是对我有用的:

1) 在每个 \n 之前添加一个额外的斜杠，使其成为 \\n

2) 在撇号 hasn\'t 之前添加额外的斜线使其 hasn\\'

"No, there is no way to hide the console window of the chromedriver.exe \\n"
                + "in the .NET bindings without modifying the bindings source code. This is seen \\n"
                + "as a feature of the bindings, as it makes it very easy to see when your code \\n"
                + "hasn\\'t correctly cleaned up the resources of the ChromeDriver, since the console window \\n"
                + "remains open. In the case of some other languages, if your code does not properly clean up \\n"
                + "the instance of ChromeDriver by calling the quit() method on the WebDriver object, \\n"
                + "you can end up with a zombie chromedriver.exe process running on your machine.";
