Java/selenium : list.clear(); очистка результата, который я пытался сохранить на карте, перед очисткой списка

#java #list #selenium

Вопрос:

Я пытался сохранить значения стран и штатов на карте с помощью пары ключ-значение каждый раз, когда я просматриваю одну страну и получаю список штатов, я пытаюсь сохранить их на карте и очистить список при выборе других стран, но list.clear(); очищая результат, который я уже сохранил на карте. пожалуйста, проведите меня сюда.

Ответ №1:

Когда вы помещаете список в качестве значения для отображения и позже очищаете список, он фактически ссылается на один и тот же объект. Таким образом, очистка списка также повлияет на значение элемента карты.

Поэтому правильный способ сделать это-создать List<String> state_names внутри for цикла.

Обновленный Код:

         Map<String, List<String>> result = new HashMap<String, List<String>>();

        for (WebElement c : countries) {
            if(!(c.getText().equalsIgnoreCase("Select Country"))) {
                
            List<String> state_names = new ArrayList<String>(); // Inside the loop
            
            c.click();
            
            List<WebElement> states = state_sel.getOptions();
        
            for (WebElement s : states) {
                if(!(s.getText().equalsIgnoreCase("Select State"))) {
                    state_names.add(s.getText());
                }
            }
            result.put(c.getText(), state_names);
            System.out.println(result);
            
        }}

Ответ №2:

@bhuvan Ваш код выглядит хорошо для меня. можете ли вы поделиться с нами html — кодом? нам будет легко предложить.

Обычно я получаю список текста, следуя следующему коду,

 public List<String> constructList(By by){
    
    List<WebElement> wholelistEle = driver.findElements(by);
    List<String> wholelist = new ArrayList<>();
    wholelistEle.forEach(ele -> {
        if(!ele.getText().equals("")){
            wholelist.add(ele.getText());
        }
    });
    log.info("Whole values found are : " wholelist.toString());
    return wholelist;
}

создайте свой xpath для опции select и перейдите к этому методу при повторении цикла стран,

 By optionXpath = By.xpath("//select//option");

List<String> stateList = constructList(optionXpath);

Ответ №3:

Вам нужно определить все state option , как только вы окажетесь внутри for each loop for country . Также и раньше going inside the inner for each loop , ты должен clear the state list .

Код:

 driver.manage().window().maximize();
WebDriverWait wait = new WebDriverWait(driver, 30);
driver.manage().timeouts().implicitlyWait(300, TimeUnit.SECONDS);
driver.get("https://frontendscript.com/demo/country-dropdown-list-javascript/");
WebElement country = driver.findElement(By.id("country"));
//WebElement state = driver.findElement(By.id("state"));
Select country_sel = new Select(country);
List<WebElement> countries = country_sel.getOptions();
Map<String, List<String>> result = new HashMap<String, List<String>>();
List<String> state_names = new ArrayList<String>();
for (WebElement c : countries) {
    if(!c.getText().equalsIgnoreCase("Select Country")) {
        c.click();
        List<WebElement> states = new Select(wait.until(ExpectedConditions.presenceOfElementLocated(By.id("state")))).getOptions();
        state_names.clear();
        for (WebElement s : states) {
            if(!s.getText().equalsIgnoreCase("Select State")) {
                //System.out.println("State name name " s.getText());
                state_names.add(s.getText());
            }
        }
        //System.out.println("Country name " c.getText());  
        //System.out.println("State name"   state_names);

        result.put(c.getText(), state_names);
    }
}
System.out.println(result);
}
