Question

如何从下拉列表循环选择所有列表选项，选择每个选项。

try {
        WebElement dropdown = RemindersElements.drpEvent(driver);
        List<WebElement> dropdownOptions = driver.findElements(By.xpath("//[@id='leftContent']/div[2]/d‌iv[1]/div/select/opt‌ion"));
        System.out.println("Dropdown Size: " + dropdownOptions.size());

        // Set value of dropdown using JS
        for (int i = 0; i < dropdownOptions.size(); i++) {
            String str = dropdownOptions.get(i).getText();
            JavascriptExecutor jse = (JavascriptExecutor) driver;
            jse.executeScript(String.format("arguments[0].value='%s';", str), dropdown);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

public static WebElement drpEvent(WebDriver driver) {
        try {
            element = driver.findElement(By.xpath("//[@id='leftContent']/div[2]/div[1]/div/select"));          
        } catch (Exception e) {
            throw (e);
        }
        return element;
    }

我想逐个选择所有选项。但是这里selenium没有给出任何错误，并且在上面的步骤之后执行下一步，我无法看到是否选择了任何选项。我想触发附加了该select元素的更改事件。并且它只会更改所选项目，但不会触发随附的更改事件。

try {
        WebElement dropdown = RemindersElements.drpEvent(driver);
        List<WebElement> dropdownOptions = dropdown.findElements(By.xpath("//option"));
        System.out.println("Dropdown Size: " + dropdownOptions.size());

        // Set value of dropdown using JS
        for (int i = 0; i < dropdownOptions.size(); i++) {
            String str = dropdownOptions.get(i).getAttribute("value");
            JavascriptExecutor jse = (JavascriptExecutor) driver;
            Thread.sleep(1500);
            jse.executeScript(String.format("arguments[0].value='%s';", str), dropdown);
            Thread.sleep(1500);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

我尝试使用类似<select>的下拉菜单，就像您在页面中所拥有的那样：

public void foo() {
    try {
        Select dropdown = new Select(RemindersElements.drpEvent(driver));
        System.out.println("Dropdown Size: " + dropdown.getOptions().size());

        for (int i = 0; i < dropdown.getOptions().size(); i++) {
            String text = dropdown.getOptions().get(i).getText();
            dropdown.selectByVisibleText(text);
            System.out.println("Option " + (i + 1) + ":" + text);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

您可能想要检查的一些事项：

查看从dropdown创建的RemindersElements.drpEvent(driver)实例是否有效。打印总选项。根据您的屏幕截图，它应该打印6。

您的循环应以索引0开头

在循环外移动try catch块，以便正确调试

更新1：
您可以尝试下面列出的其他几件事。只要您的RemindersElements.drpEvent(driver)返回有效元素，这些就应该有效。

public void bar() {
    try {
        WebElement dropdown = RemindersElements.drpEvent(driver);
        List<WebElement> dropdownOptions = dropdown.findElements(By.xpath("//option"));
        System.out.println("Dropdown Size: " + dropdownOptions.size());

        // Click the dropdown and click each option one by one
        for (int i = 0; i < dropdownOptions.size(); i++) {
            dropdown.click();
            dropdownOptions.get(i).click();
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void baz() {
    try {
        WebElement dropdown = RemindersElements.drpEvent(driver);
        List<WebElement> dropdownOptions = dropdown.findElements(By.xpath("//option"));
        System.out.println("Dropdown Size: " + dropdownOptions.size());

        // Set value of dropdown using JS
        for (int i = 0; i < dropdownOptions.size(); i++) {
            String str = dropdownOptions.get(i).getText();
            JavascriptExecutor jse = (JavascriptExecutor) driver;
            jse.executeScript(String.format("arguments[0].value='%s';", str), dropdown);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

更新2：
将其添加到RemindersElements类中：

public static List <WebElement> drpEventOpts(WebDriver driver) {
        try {
            List <WebElement> elements = driver.findElements(By.xpath("//[@id='leftContent']/div[2]/div[1]/div/select/option"));          
        } catch (Exception e) {
            throw (e);
        }
        return elements;
    }

然后替换这一行：

List<WebElement> dropdownOptions = RemindersElements.drpEventOpts(driver);

Answer 2

尝试这个

public static void  checkDropdownAllOption(WebDriver driver,WebElement lelement)
{
    Select oSelect = new Select(lelement);
    java.util.List <WebElement> elementCount = oSelect.getOptions();
    int iSize = elementCount.size();
    String [] arrdropdown= new String [iSize];          
    for (int j = 0; j < iSize; j++) 
    {
        arrdropdown[j]=elementCount.get(j).getText();
    }

    WebElement mySelectElm = lelement;              
    Select mySelect= new Select(mySelectElm);       
    for (int i = 0; i < arrdropdown.length; i++) 
    {
        mySelect.selectByVisibleText(arrdropdown[i]);
    }   
}
