无法对位于 Flexbox 下的元素执行任何操作

Question

Selenium能够访问findElement位于flex框下的元素，但无法对这些元素执行任何操作。下面我提供了几个示例网站以供详细了解，

示例#1：

网站：https : //condos.ca/

  </button>
   </div>
</div>

代码：

driver.get("https://condos.ca");
driver.findElement(By.xpath("//input[@id='search-input']")).sendKeys("test");

结果：正在执行步骤，没有抛出任何错误，但未输入文本。

示例#2：

网站：https : //demoqa.com/slider

HTML片段：

driver.get("https://condos.ca");
driver.findElement(By.xpath("//input[@id='search-input']")).sendKeys("test");

代码：

driver.get("https://demoqa.com/slider");
JavascriptExecutor executor = (JavascriptExecutor) driver;
WebElement slider = driver.findElement(By.xpath("//input[@type='range']"));
System.out.println("Cuurent value: " + slider.getAttribute("value"));
executor.executeScript("arguments[0].setAttribute('value', ' 30 ')", slider);

结果：打印属性值但未设置新值。

很少有问题和博客建议使用Selenium flex api来自动化这些类型的应用程序，但我可以看到安装 eclipse 的 flex 插件的先决条件，但我找不到。另外，这些帖子有点旧（5 年前）。

• 如何处理这些元素？
• 有什么新方法可以做到这一点吗？

示例 1 的解决方案

如果加载该网站，您会发现搜索编辑框上方的文本最初如下所示：

一段时间后，同一元素的文本更改为：

只有发生这种情况后，才尝试执行 sendkeys 操作。请注意，您不必对 id = 'search-input' 的元素执行 sendkeys 操作。您首先需要单击该元素，然后另一个元素（cssSelector -> div[role='combobox'] [placeholder='Search by address, Neighbourhood, MLS #']）变得可见，您必须在其上执行 sendkeys 操作。

请参考下面的代码（在 chrome、edge 和 firefox 上测试）。

package usecase;

import java.time.Duration;
import java.util.regex.Pattern;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

import io.github.bonigarcia.wdm.WebDriverManager;

public class Flexcase {
    public static WebDriver driver;
    private static final int maxtime = 20;

    /**
     * Creating a custom findElement method that uses Explicit wait and waits for an
     * element to be clickable
     */
    public static WebElement findElement(By by) {
        WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(maxtime));
        return wait.until(ExpectedConditions.elementToBeClickable(by));
    }

    /**
     * Waits for an element to contain a text matched by the given pattern(regex)
     */
    public static Boolean doesElementContainTextPattern(By by, String pattern) {
        WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(maxtime));
        return wait.until(ExpectedConditions.textMatches(by, Pattern.compile(pattern)));
    }

    public static void main(String[] args) throws InterruptedException {
        WebDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://condos.ca/");
        // Waiting for the text to achieve a specific pattern - Search followed by 1+
        // occurrences of either digits or commas followed by 0+ occurrences of any
        // character that is not a newline character followed by the word Listings
        if (doesElementContainTextPattern(By.className("dPFjpJ"), "Search [\\d,]+.*Listings")) {
            findElement(By.id("search-input")).click();
            findElement(By.cssSelector("div[role='combobox'] [placeholder='Search by address, Neighbourhood, MLS #']"))
                    .sendKeys("Test");
        }

        Thread.sleep(10000); // Pls let me see what's happening on the screen
        driver.quit();
    }
}

例2的解决方案

我没有使用 javascriptexecutor，而是使用 Actions 类来构建由以下操作组成的复合操作：

• 通过查找滑块宽度（以像素为单位）将鼠标移动到滑块的最左边位置
• 将鼠标移动到滑块上的所需位置，与传递的百分比值成比例

代码：（滑动精度可提高）

package usecase;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

import io.github.bonigarcia.wdm.WebDriverManager;

public class Slider {

    public static WebDriver driver;

    public static void moveSliderToPosition(By by, int percentage) throws InterruptedException {
        WebElement slider = driver.findElement(by);
        Actions builder = new Actions(driver);
        builder.moveToElement(slider, (int) (-slider.getRect().width / 2), 0) // move to the leftmost position of the
                                                                                // element
                .moveByOffset((int) (percentage * slider.getRect().width / 100), 0) // move the cursor by an offset
                                                                                    // proportionate to the value passed
                .click().build().perform();
        Thread.sleep(3000); // let me see what has happened on the screen
    }

    public static void main(String[] args) throws InterruptedException {
        WebDriverManager.chromedriver().setup();
        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://demoqa.com/slider");
        By slider = By.cssSelector("input.range-slider");
        moveSliderToPosition(slider, 47);
        moveSliderToPosition(slider, 83);
        moveSliderToPosition(slider, 35);
        driver.quit();
    }
}
