org.openqa.selenium.JavascriptException:SyntaxError:''；通过Selenium使用executeScript时，字符串文字包含未转换的换行符

org.openqa.selenium.JavascriptException:SyntaxError:“”字符串文字在通过selenium使用executeScript时包含未替换的换行符

executeScript（）

可以完美地处理单行字符串，例如：

String myText = "80120804076";

但当我试图发送多行字符串时，会引发

JavascriptException

• 代码试用：

还是不知道我哪里出了问题。有人能帮我吗？

你试过这个方法吗：

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

以下是对我有效的方法：

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

未

之前添加了额外的斜杠，使其

未\\\\\

"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.";

谢谢显示错误，因为类型send_large_text-Syntax error on token“.”的方法join（String）未定义；预期的
