要素について学ぶことができること。

特定の要素についてクエリできる詳細情報がいくつかあります。

表示されているかどうか

This method is used to check if the connected Element is displayed on a webpage. Returns a Boolean value, True if the connected element is displayed in the current browsing context else returns false.

This functionality is mentioned in, but not defined by the w3c specification due to the impossibility of covering all potential conditions. As such, Selenium cannot expect drivers to implement this functionality directly, and now relies on executing a large JavaScript function directly. This function makes many approximations about an element’s nature and relationship in the tree to return a value.

// Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html");

// Get boolean value for is element display
boolean isEmailVisible = driver.findElement(By.name("email_input")).isDisplayed();
# Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html")

# Get boolean value for is element display
is_email_visible = driver.find_element(By.NAME, "email_input").is_displayed()
//Navigate to the url
driver.Url = "https://www.selenium.dev/selenium/web/inputs.html";

//Get boolean value for is element display
Boolean is_email_visible = driver.FindElement(By.Name("email_input")).Displayed;
# Navigate to the url
driver.get("https://www.selenium.dev/selenium/web/inputs.html");

#fetch display status
val = driver.find_element(name: 'email_input').displayed?
// Navigate to url
await driver.get("https://www.selenium.dev/selenium/web/inputs.html");

// Resolves Promise and returns boolean value
let result =  await driver.findElement(By.name("email_input")).isDisplayed();
// Help us with a PR for code sample

要素が有効か

このメソッドは、接続された要素がWebページで有効または無効になっているかどうかを確認するために使います。 ブール値を返し、現在のブラウジングコンテキストで接続されている要素が 有効（enabled） になっている場合は True 、そうでない場合は false を返します。

//navigates to url
driver.get("https://www.google.com/");

//returns true if element is enabled else returns false
boolean value = driver.findElement(By.name("btnK")).isEnabled();
# Navigate to url
driver.get("http://www.google.com")

# Returns true if element is enabled else returns false
value = driver.find_element(By.NAME, 'btnK').is_enabled()
// Navigate to Url
driver.Navigate().GoToUrl("https://google.com");

// Store the WebElement
IWebElement element = driver.FindElement(By.Name("btnK"));

// Prints true if element is enabled else returns false
System.Console.WriteLine(element.Enabled);
# Navigate to url
driver.get 'http://www.google.com/'

# Returns true if element is enabled else returns false
ele = driver.find_element(name: 'btnK').enabled?
// Navigate to url
await driver.get('https://www.google.com');

// Resolves Promise and returns boolean value
let element =  await driver.findElement(By.name("btnK")).isEnabled();
//navigates to url
driver.get("https://www.google.com/")

//returns true if element is enabled else returns false
val attr = driver.findElement(By.name("btnK")).isEnabled()

要素が選択されているかどうか

このメソッドは、参照された要素が選択されているかどうかを判断します。 このメソッドは、チェックボックス、ラジオボタン、入力要素、およびオプション要素で広く使われています。

ブール値を返し、現在のブラウジングコンテキストで参照された要素が 選択されている 場合は True 、そうでない場合は false を返します。

//navigates to url
driver.get("https://the-internet.herokuapp.com/checkboxes");

//returns true if element is checked else returns false
boolean value = driver.findElement(By.cssSelector("input[type='checkbox']:first-of-type")).isSelected();
# Navigate to url
driver.get("https://the-internet.herokuapp.com/checkboxes")

# Returns true if element is checked else returns false
value = driver.find_element(By.CSS_SELECTOR, "input[type='checkbox']:first-of-type").is_selected()
// Navigate to Url
driver.Navigate().GoToUrl("https://the-internet.herokuapp.com/checkboxes");

// Returns true if element ins checked else returns false
bool value = driver.FindElement(By.CssSelector("input[type='checkbox']:last-of-type")).Selected;
# Navigate to url
driver.get 'https://the-internet.herokuapp.com/checkboxes'

# Returns true if element is checked else returns false
ele = driver.find_element(css: "input[type='checkbox']:last-of-type").selected?
// Navigate to url
await driver.get('https://the-internet.herokuapp.com/checkboxes');

// Returns true if element ins checked else returns false
let res = await driver.findElement(By.css("input[type='checkbox']:last-of-type")).isSelected();
//navigates to url
driver.get("https://the-internet.herokuapp.com/checkboxes")

//returns true if element is checked else returns false
val attr =  driver.findElement(By.cssSelector("input[type='checkbox']:first-of-type")).isSelected()

# Navigate to url
driver.get("https://www.example.com")

# Returns TagName of the element
attr = driver.find_element(By.CSS_SELECTOR, "h1").tag_name
// Navigate to Url
driver.Navigate().GoToUrl("https://www.example.com");

// Returns TagName of the element
string attr = driver.FindElement(By.CssSelector("h1")).TagName;
# Navigate to url
driver.get 'https://www.example.com'
