ElementNotVisible异常Selenium Webdriver Java

Question

我正在公共网站上工作：
http://preview.harriscountyfws.org/

下面显示的逻辑遇到ElementNotVisibleException。 但是，如果取消注释以“ //”开头的两行，并注释掉该代码上方的两行，则该代码可以正常工作（但是，这与我想要的下拉菜单不同）。

所以我很困惑。 我可以从“最后一次降雨”下拉菜单中进行选择。 但是，使用完全相同的方法，我无法从“按位置分类”下拉菜单中进行选择。

如何从按地点分类的量具中选择？

package sdfwe.sdwd.qsde;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class Gfgsdrfffde {
    public static void main(String[] args) {
        System.out.println("Running Tests....");
        // Optional, if not specified, WebDriver will search your path for chromedriver.
        System.setProperty("webdriver.chrome.driver", "C:\\ChromeDriver\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("http://preview.harriscountyfws.org/");
        driver.manage().window().maximize();
        WebElement we;
        String searchText;
        WebElement dropdown;
        //if you comment out the next two lines after these comments and
        // uncomment out the commented lines below, the code works
        searchText = "110:A100_110 Clear Creek @45";
        dropdown = driver.findElements(By.cssSelector("span.k-widget")).get(3);
    //        searchText = "24 Hours";
    //        dropdown = driver.findElements(By.cssSelector("span.k-widget")).get(1);
        System.out.println("Attempting Dropdown Click....");
        dropdown.click();
        System.out.println("Finished running Dropdown Click....");
        Sleep(4);
        //Select dd2 = new Select(driver.findElement(By.id("ddlTimeSpan")));
        //dd2.selectByVisibleText(searchText);
        we = driver.findElement(By.xpath("//li[text()='" + searchText + "']"));
        if (we != null) {
            we.click();
        }
        System.out.println("Finished Selecting Dropdown....");
        //driver.quit();
    }
    public static void Sleep(int i)
    {
        try { Thread.sleep(i * 300); }
        catch(InterruptedException ie) { System.out.println("Unexpected error in sleep"); }
    }
}

Answer 1

您可以尝试以下方法：

    WebDriverWait wait = new WebDriverWait(driver, 10);
    wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("select#ddlGage")));
    Select gageByLocationSelect = new Select(driver.findElement(By.cssSelector("select#ddlGage")));
    gageByLocationSelect.selectByVisibleText("110:A100_110 Clear Creek @ I-45");

希望这个能对您有所帮助！！

Answer 2

我尝试了您的代码，您需要进行以下更改才能使其正常工作：

    searchText = "110:A100_110 Clear Creek @ I-45";
    dropdown = driver.findElement(By.cssSelector("span[aria-owns='ddlGage_listbox']"));

这是您上面示例中的完整工作代码。

       public static void main(final String[] args) {
    System.out.println("Running Tests....");
    // Optional, if not specified, WebDriver will search your path for
    // chromedriver.
    System.setProperty("webdriver.chrome.driver", "C:\\ChromeDriver\\chromedriver.exe");
    final WebDriver driver = new ChromeDriver();
    driver.get("http://preview.harriscountyfws.org/");
    driver.manage().window().maximize();
    WebElement we;
    String searchText;
    WebElement dropdown;
    // if you comment out the next two lines after these comments and
    // uncomment out the commented lines below, the code works
    searchText = "110:A100_110 Clear Creek @ I-45";
    dropdown = driver.findElement(By.cssSelector("span[aria-owns='ddlGage_listbox']"));
    // searchText = "24 Hours";
    // dropdown =
    // driver.findElements(By.cssSelector("span.k-widget")).get(1);
    System.out.println("Attempting Dropdown Click....");
    dropdown.click();
    System.out.println("Finished running Dropdown Click....");
    Sleep(4);
    // Select dd2 = new Select(driver.findElement(By.id("ddlTimeSpan")));
    // dd2.selectByVisibleText(searchText);
    we = driver.findElement(By.xpath("//li[text()='" + searchText + "']"));
    if (we != null) {
        we.click();
    }
    System.out.println("Finished Selecting Dropdown....");
    // driver.quit();
} 

另外，对于简单的Selenium脚本，您可能需要检查https://github.com/codezombies/easytest 。

这是使用easytest框架的相同脚本。

public static void main(String[] args) throws Exception {

    try(EasyTest easy = new EasyTest(DriverType.CHROME)) {


        easy.start("http://preview.harriscountyfws.org/");

        easy.newPage(page -> {
           page.click("span[aria-owns='ddlGage_listbox']");

           final String searchText = "110:A100_110 Clear Creek @ I-45";
           page.executeIn("#ddlGage_listbox", container -> {
               page.click("//li[text()='" + searchText + "']");
           });

        });
    }
}
