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")
