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。
driver.get("https://www.selenium.dev/selenium/web/inputs.html");
// isDisplayed
// Get boolean value for is element display
boolean isEmailVisible = driver.findElement(By.name("email_input")).isDisplayed();
assertEquals(isEmailVisible,true);# 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 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;
Assert.AreEqual(isEmailVisible, true); 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
boolean isEnabledButton = driver.findElement(By.name("button_input")).isEnabled();
assertEquals(isEnabledButton,true);# 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() //isEnabled
//returns true if element is enabled else returns false
bool isEnabledButton = driver.FindElement(By.Name("button_input")).Enabled;
Assert.AreEqual(isEnabledButton, true); 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
boolean isSelectedCheck = driver.findElement(By.name("checkbox_input")).isSelected();
assertEquals(isSelectedCheck,true); # 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() //isSelected
//returns true if element is checked else returns false
bool isSelectedCheck = driver.FindElement(By.Name("checkbox_input")).Selected;
Assert.AreEqual(isSelectedCheck, true); 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
String tagNameInp = driver.findElement(By.name("email_input")).getTagName();
assertEquals(tagNameInp,"input"); # 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 //TagName
//returns TagName of the element
string tagNameInp = driver.FindElement(By.Name("email_input")).TagName;
Assert.AreEqual(tagNameInp, "input"); 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
Rectangle res = driver.findElement(By.name("range_input")).getRect();
// Rectangle class provides getX,getY, getWidth, getHeight methods
assertEquals(res.getX(),10);# Navigate to url
driver.get("https://www.selenium.dev/selenium/web/inputs.html")
# Returns height, width, x and y coordinates referenced element
res = driver.find_element(By.NAME, "range_input").rect //Get Location and Size
//Get Location

Point point = rangeElement.Location;
Assert.IsNotNull(point.X);
//Get Size
int height=rangeElement.Size.Height;
Assert.IsNotNull(height); size = driver.find_element(name: 'email_input').size// 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

// Retrieves the text of the element
string text = driver.FindElement(By.TagName("h1")).Text;
