Question

功能：我们有三个字段Country，State，City -

选择国家后，它会显示州名单，选择州后会显示城市列表。

问题：在这个州没有城市，所以如何找到国家，国家列出那些没有城市列表使用硒？

我尝试了下面的代码，但循环不起作用＆amp;不显示空列表

@Test
public void findstate() throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("URL");
    Select country = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCountryId']")));
    List<WebElement> countrylist = country.getOptions();
    System.out.println(countrylist.size());
    for (int i = 1; i <= countrylist.size(); i++) {
        countrylist.get(i).click();
        Select state = new Select(driver.findElement(By.xpath("//*[@id='UserProfileStateId']")));
        List<WebElement> statelist = state.getOptions();
        for (int j = 1; j <= statelist.size(); j++) {
            statelist.get(j).click();
            Select city = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCityId']")));
            List<WebElement> citylist = city.getOptions();
            System.out.println("Country, state list of Empty Cities");
            if (citylist.size() > 1) {
                System.out.println(countrylist.get(i).getText() + "-----" + statelist.get(j).getText() + "-----");
            }

        }

    }

}

国家，州，城市的源代码：

<span class="select-wrapper"><select name="data[UserProfile][country_id]" class="custom-select valid" id="UserProfileCountryId" aria-invalid="false" aria-required="true">
<option value="">Country</option>
<option value="1">Afghanistan</option>
<option value="2">Albania</option>
</select><span class="holder">Afghanistan</span></span>
<select name="data[UserProfile][state_id]" class="custom-select valid" id="UserProfileStateId" aria-invalid="false" aria-required="true">
<option value="">State</option>
<option value="42">Badakhshan</option>
<option value="43">Badgis</option>
<option value="44">Baglan</option>
</select>
<select name="data[UserProfile][city_id]" class="custom-select valid" id="UserProfileCityId" aria-invalid="false" aria-required="true">
<option value="">City</option>
<option value="5916">Andarab</option>
<option value="5917">Baghlan</option>
</select>

我认为，由于复制和粘贴，你有一些拼写错误。

您需要在循环中使用正确的Select变量，但始终使用country。

试试这个：

@Test
public void findstate() throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("URL");
    Select country = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCountryId']")));
    List<WebElement> countrylist = country.getOptions();
    System.out.println(countrylist.size());
    for (int i = 1; i <= countrylist.size(); i++) {
        countrylist.get(i).click();
        Select state = new Select(driver.findElement(By.xpath("//*[@id='UserProfileStateId']")));
        List<WebElement> statelist = state.getOptions();
        for (int j = 1; j <= statelist.size(); j++) {
            statelist.get(j).click();
            Select city = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCityId']")));
            List<WebElement> citylist = city.getOptions();
            System.out.println("Country, state list of Empty Cities");
            if (citylist.size() > 1) {
                System.out.println(countrylist.get(i).getText() + "-----" + statelist.get(j).getText() + "-----");
            }

        }

    }

}

为了避免这个错误，最好像这样使用foreach循环：

for (WebElement element : country.getOptions()) { }

我不知道您的HTML代码，但在询问getOptions()之前，等待其他下拉菜单填充元素也可能。 Selenium非常快，它可能会在您的网站加载之前询问下拉菜单的选项。在这种情况下，即使使用更新的代码也不会得到任何结果。

每次都尝试等待下拉菜单填写：

Select country = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCountryId']"))); List<WebElement> countrylist = country.getOptions(); System.out.println(countrylist.size()); for (WebElement element : countrylist) { element.click(); Select state = new Select(driver.findElement(By.xpath("//*[@id='UserProfileStateId']"))); WebDriverWait wait = new WebDriverWait(driver, 30); wait.until(new Function<WebDriver, WebElement>() { public WebElement apply(WebDriver webdriver) { return state.getOptions() > 1; } }); List<WebElement> statelist = state.getOptions(); ....

您对城市选项也这样做 - ＆gt;如果你遇到超时，你会发现没有城市的州......

嗨，请尝试如下

@Test
public void findstate() throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("URL");
    WebDriverWait wait = new WebDriverWait(driver,20);
    Select country = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCountryId']")));
    List<WebElement> countrylist = country.getOptions();
    System.out.println(countrylist.size());
    for (int i = 0; i <= countrylist.size(); i++) {
        countrylist.get(i).click();
        wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='UserProfileStateId']")));
        Select state = new Select(driver.findElement(By.xpath("//*[@id='UserProfileStateId']")));
        // here use state not country
        List<WebElement> statelist = state.getOptions();
        for (int j = 0; j <= statelist.size(); j++) {
            statelist.get(j).click();
            wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='UserProfileCityId']")));
            Select city = new Select(driver.findElement(By.xpath("//*[@id='UserProfileCityId']")));
         // here use city not country
            List<WebElement> citylist = city.getOptions();
            for (int k = 0; k <= citylist.size(); k++) {
                citylist.get(k).click();
                System.out.println("Country, state list of Empty Cities");
                if (citylist.get(k).getText() == null) {
                    System.out.println(countrylist.get(i).getText() + "-----" + statelist.get(j).getText() + "-----"+ citylist.get(k).getText());
                }
            }
        }
    }
}

Answer 3

在最外层循环选择国家/地区，然后在内部循环中选择该国家/地区的每个州，并检查是否找到了城市。如果没有，那么得到城市＆amp;国家和地区走这条路。

我认为，它可以帮助你。

Answer 4

它工作正常，选择国家后添加'tab'键

driver.findElement(By.xpath("//*@id='UserProfileCountryId']")).sendKeys(Keys.TAB);

但是我在执行时遇到了另一个问题，经过一段时间后运行脚本我得到了错误 org.openqa.selenium.StaleElementReferenceException：元素不再附加到DOM 命令持续时间或超时：31毫秒
