关于网络元素的信息

元素相关的知识.

您可以查询有关特定元素的许多详细信息。

是否显示

此方法用于检查连接的元素是否正确显示在网页上. 返回一个 Boolean 值，如果连接的元素显示在当前的浏览器上下文中，则为True，否则返回false。

此功能于W3C规范中提及，但由于无法覆盖所有潜在条件而无法定义。因此，Selenium不能期望驱动程序直接实现这种功能，现在依赖于直接执行大量JavaScript函数。这个函数对一个元素的性质和在树中的关系做了许多近似的判断，以返回一个值。

// 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?

    // Resolves Promise and returns boolean value
    let result =  await driver.findElement(By.name("email_input")).isDisplayed();

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

 //returns true if element is displayed else returns false
 val flag = driver.findElement(By.name("email_input")).isDisplayed()

是否启用

此方法用于检查所连接的元素在网页上是启用还是禁用状态。返回一个布尔值，如果在当前浏览上下文中是启用状态，则返回 true，否则返回 false。

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

  //returns true if element is enabled else returns false
  boolean value = driver.findElement(By.name("button_input")).isEnabled();

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

    # Returns true if element is enabled else returns false
value = driver.find_element(By.NAME, 'button_input').is_enabled()

// Navigate to Url
driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/inputs.html");

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

// Prints true if element is enabled else returns false
System.Console.WriteLine(element.Enabled);

    # Navigate to url
driver.get 'https://www.selenium.dev/selenium/web/inputs.html'

    # Returns true if element is enabled else returns false
ele = driver.find_element(name: 'button_input').enabled?

    // Resolves Promise and returns boolean value
    let element =  await driver.findElement(By.name("button_input")).isEnabled();

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

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

是否被选定

此方法确认相关的元素是否 已选定，常用于复选框、单选框、输入框和选择元素中。

该方法返回一个布尔值，如果在当前浏览上下文中 选择了 引用的元素，则返回 True，否则返回 False。

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

 //returns true if element is checked else returns false
 boolean value = driver.findElement(By.name("checkbox_input")).isSelected();

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

    # Returns true if element is checked else returns false
value = driver.find_element(By.NAME, "checkbox_input").is_selected()

// Navigate to Url
driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/inputs.html");

// Returns true if element ins checked else returns false
bool value = driver.FindElement(By.Name("checkbox_input")).Selected;

    # Navigate to url
driver.get 'https://www.selenium.dev/selenium/web/inputs.html'

    # Returns true if element is checked else returns false
ele = driver.find_element(name: "checkbox_input").selected?

    // Returns true if element ins checked else returns false
    let isSelected = await driver.findElement(By.name("checkbox_input")).isSelected();

 //returns TagName of the element
 String value = driver.findElement(By.name("email_input")).getTagName();

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

    # Returns TagName of the element
attr = driver.find_element(By.NAME, "email_input").tag_name

// Navigate to Url
