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 Url  driver.get("https://www.selenium.dev/selenium/web/inputs.html");   // isDisplayed  // Get boolean value for is element display
 driver.get("https://www.selenium.dev/selenium/web/inputs.html")   # isDisplayed  is_email_visible = driver.find_element(By.NAME, "email_input").is_displayed()
 // Navigate to Url  driver.Url= "https://www.selenium.dev/selenium/web/inputs.html";  // isDisplayed   // Get boolean value for is element display  bool isEmailVisible = driver.FindElement(By.Name("email_input")).Displayed;
 displayed_value = 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。

  // isEnabled  // returns true if element is enabled else returns false
 is_enabled_button = driver.find_element(By.NAME, "button_input").is_enabled()
 // isEnabled  // returns true if element is enabled else returns false  bool isEnabledButton = driver.FindElement(By.Name("button_input")).Enabled;
 enabled_value = driver.find_element(name: 'email_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。

  // isSelected  // returns true if element is checked else returns false
 is_selected_check = driver.find_element(By.NAME, "checkbox_input").is_selected()
 // isSelected  // returns true if element is checked else returns false  bool isSelectedCheck = driver.FindElement(By.Name("checkbox_input")).Selected;
 selected_value = driver.find_element(name: 'email_input').selected?
 // Returns true if element ins checked else returns false  let isSelected = await driver.findElement(By.name("checkbox_input")).isSelected();
//navigates to url driver.get("https://www.selenium.dev/selenium/web/inputs.html")  //returns true if element is checked else returns false val attr = driver.findElement(By.name("checkbox_input")).isSelected()

获取元素标签名

此方法用于获取在当前浏览上下文中具有焦点的被引用元素的TagName。

  // TagName  // returns TagName of the element
 tag_name_inp = driver.find_element(By.NAME, "email_input").tag_name
 // TagName  // returns TagName of the element  string tagNameInp = driver.FindElement(By.Name("email_input")).TagName;
 tag_name = driver.find_element(name: 'email_input').tag_name
 // Returns TagName of the element  let value = await driver.findElement(By.name('email_input')).getTagName();
//navigates to url driver.get("https://www.selenium.dev/selenium/web/inputs.html")  //returns TagName of the element val attr = driver.findElement(By.name("email_input")).getTagName()

位置和大小

用于获取参照元素的尺寸和坐标。

提取的数据主体包含以下详细信息：

  • 元素左上角的X轴位置
  • 元素左上角的y轴位置
  • 元素的高度
  • 元素的宽度
  // GetRect  // Returns height, width, x and y coordinates referenced element
 rect = driver.find_element(By.NAME, "range_input").rect
 // Get Location and Size  // Get Location  IWebElement rangeElement = driver.FindElement(By.Name("range_input"));  Point point = rangeElement.Location;
 size = driver.find_element(name: 'email_input').size
 let object = await driver.findElement(By.name('range_input')).getRect();
// Navigate to url driver.get("https://www.selenium.dev/selenium/web/inputs.html")  // Returns height, width, x and y coordinates referenced element val res = driver.findElement(By.name("range_input")).rect  // Rectangle class provides getX,getY, getWidth, getHeight methods println(res.getX())

获取元素CSS值

获取当前浏览上下文中元素的特定计算样式属性的值。

 // Retrieves the computed style property 'font-size' of field  String cssValue = driver.findElement(By.name("color_input")).getCssValue("font-size");
 css_value = driver.find_element(By.NAME, "color_input").value_of_css_property(  "font-size"  )
 // Retrieves the computed style property 'font-size' of field  string cssValue = driver.FindElement(By.Name("color_input")).GetCssValue("font-size");
 css_value = driver.find_element(name: 'email_input').css_value('background-color')
 await driver.get('https://www.selenium.dev/selenium/web/colorPage.html');  // Returns background color of the element  let value = await driver.findElement(By.id('namedColor')).getCssValue('background-color');
// Navigate to Url driver.get("https://www.selenium.dev/selenium/web/colorPage.html")  // Retrieves the computed style property 'color' of linktext val cssValue = driver.findElement(By.id("namedColor")).getCssValue("background-color")

文本内容

获取特定元素渲染后的文本内容。

 // GetText  // Retrieves the text of the element  String text = driver.findElement(By.tagName("h1")).getText();
 text = driver.find_element(By.TAG_NAME, "h1").text
 // GetText  // Retrieves the text of the element  string text = driver.FindElement(By.TagName("h1")).Text;
 text = driver.find_element(xpath: '//h1').text
 await driver.get('https://www.selenium.dev/selenium/web/linked_image.html');  // Returns text of the element  let text = await driver.findElement(By.id('justanotherLink')).getText();
// Navigate to URL driver.get("https://www.selenium.dev/selenium/web/linked_image.html")  // retrieves the text of the element val text = driver.findElement(By.id("justanotherlink")).getText()

获取特性或属性

获取与 DOM 属性关联的运行时的值。 它返回与该元素的 DOM 特性或属性关联的数据。

 // FetchAttributes  // identify the email text box  WebElement emailTxt = driver.findElement(By.name(("email_input")));  // fetch the value property associated with the textbox  String valueInfo = emailTxt.getAttribute("value");
 # FetchAttributes  email_txt = driver.find_element(By.NAME, "email_input")  value_info = email_txt.get_attribute("value")
 // FetchAttributes  // identify the email text box  IWebElement emailTxt = driver.FindElement(By.Name("email_input"));  // fetch the value property associated with the textbox  string valueInfo = emailTxt.GetAttribute("value");
 attribute_value = driver.find_element(name: 'number_input').attribute('value')
 // identify the email text box  const emailElement = await driver.findElement(By.xpath('//input[@name="email_input"]'));   //fetch the attribute "name" associated with the textbox  const nameAttribute = await emailElement.getAttribute("name");
// Navigate to URL driver.get("https://www.selenium.dev/selenium/web/inputs.html")  //fetch the value property associated with the textbox val attr = driver.findElement(By.name("email_input")).getAttribute("value")
