Question

TestCase类是我启动驱动程序并调用url的地方（url“http://www.amazon.in/”）

<form #f="ngForm" novalidate>
    <div class="checkbox checkbox-primary" *ngFor="let categoryname of Food.category; let i = index">
        <label for="categoryname">          
         <input type = "checkbox" name="{{i}}" [(ngModel)]="Catcheckbox" (click)="onClick(categoryname)" value="{{categoryname}}"/>
        {{categoryname}}
        </label>
    </div>  
     <button type="submit" (click)="save(f.value, f.valid)" class="btn btn-default">Submit</button>
</form>

TC1是我去亚马逊登录页面的测试

public class TestCase { 
    InitializeDriver id = new InitializeDriver();
    WebDriver driver = null;

    @BeforeTest
    public void setup()
    {
        id.invokeApplicationUrl();
        driver = id.getDriver();

    }

}

转到登录页面的逻辑是用GoToSignPage编写的

public class TC1 extends TestCase {
    @Test
    public void runTC1 () 
    {
        GoToSignInPage gts = new GoToSignInPage(driver);
        gts.clickElement();
    }
}

InitialPage类具有所有必需的页面对象

public class GoToSignInPage {

    WebDriver driver;

    public GoToSignInPage(WebDriver driver)
    {
        this.driver=driver;
    }

    InitialPage ip = new InitialPage(driver);
    InitializeDriver id = new InitializeDriver();

    public void clickElement()
    {
        Actions action = new Actions(driver);
        //driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);
        JavascriptExecutor jse = (JavascriptExecutor)driver;
        //ip.yourOrders(driver).click();
        jse.executeScript("argument[0].style.border='3px dotted blue'", ip.yourOrders(driver));
action.moveToElement(ip.yourOrders(driver)).moveToElement(ip.signInBt(driver)).click().build().perform();
}

错误如下

org.openqa.selenium.WebDriverException：未知错误：未定义参数（会议信息：chrome = 56.0.2924.87）（驱动程序信息：chromedriver = 2.24.417431（9aea000394714d2fbb20850021f6204f2256b9cf），platform = Windows NT 6.3.9600 x86_64）（警告：服务器未提供任何堆栈跟踪信息）命令持续时间或超时：22毫秒构建信息：版本：'3.0.0-beta1'，修订版：'8e4315c'，时间：'2016-07-28 18:04:05 -0700' 系统信息：主机：'VAIO'，ip：'192.168.0.6'，os.name：'Windows 8.1'，os.arch：'amd64'，os.version：'6.3'，java.version：'1.8.0_45 “ 驱动程序信息：org.openqa.selenium.chrome.ChromeDriver 能力[{applicationCacheEnabled =假，可旋转=假，mobileEmulationEnabled =假，networkConnectionEnabled =假，铬= {chromedriverVersion = 2.24.417431（9aea000394714d2fbb20850021f6204f2256b9cf），userDataDir = C：\用户\阿卡什\应用程序数据\本地\ TEMP \ scoped_dir6352_11834}，takesHeapSnapshot = true，pageLoadStrategy = normal，databaseEnabled = false，handlesAlerts = true，hasTouchScreen = false，version = 56.0.2924.87，platform = WIN8_1，browserConnectionEnabled = false，nativeEvents = true，acceptSslCerts = true，locationContextEnabled = true，webStorageEnabled = true，browserName = chrome，takesScreenshot = true，javascriptEnabled = true，cssSelectorsEnabled = true}] 会议ID：f74e69d9f66bab833287a8fd6f9d3021 at sun.reflect.NativeConstructorAccessorImpl.newInstance0（Native Method）

Answer 1

一个简单的解决方案是将jse.executeScript（“ argument [0] .style.border ='3px dotted blue'”更改为jse.executeScript（“ arguments [0] .style.border ='3px点缀蓝色'“，

Answer 2

您的错误来自执行此JavaScript代码jse.executeScript("argument[0].style.border='3px dotted blue'"，尝试在浏览器中加载网站（即Chrome），打开开发人员工具（F12），导航到控制台，输入相同的命令，您将获得同样的错误：

根据Selenium documentation，

这些参数将通过＆＃34;参数＆＃34;提供给JavaScript。变量

在您的代码中，您使用argument[0]代替arguments[0]

从Selenium运行javascript时出现“参数未定义”错误
