Object Positioning

Webdriver provides a range of element positioning methods, which are commonly used in the following ways:

• Id

• Name

• Class name

• Tag name

• Link text

• Partial link text

• Xpath

• CSS Selector

The methods that correspond to Python webdriver are:

• FIND_ELEMENT_BY_ID ()

• Find_element_by_name ()

• Find_element_by_class_name ()

• Find_element_by_tag_name ()

• Find_element_by_link_text ()

• Find_element_by_partial_link_text ()

• Find_element_by_xpath ()

• Find_element_by_css_selector ()

  Let's take blog.hexun.com as an example:
  
  This is his login box. Press F12 or right mouse button to select Inspect in Firepath Firefox will pop up to view the element interface:
  
  Click on the arrows as shown there, then go to the page where you want to locate the element, for example we now want to locate the input account box, we will click on the view element of the icon, and then click on the Input Account box, you can see the view element of the page is located here:
  
  Here, the page element property has ID, name, and so on, which is where we can locate this box by ID (find_element_by_id) or name (Find_element_by_name), generally name or class_name,tag_ Name these element names are not unique, possibly called DIV (tag_name) Another place also called Div, here is called name= "username", another place name is also username, this time with Name,class_name,tag_ Name is very difficult to locate the element you want, so, do not hesitate, not too long to use XPath or Css_selector bar, if there is ID can also, because generally the ID is definitely unique.
  How does name locate XPath or css_selector? That's the view page element there selection
  
  Firepath that tag, already see the XPath of the account bar, just click on the small triangle behind the XPath, you can switch to CSS (that is, Css_selector) positioning method:
  
  So, in the future when the positioning of the time basically without thinking, directly with Firepath This tool can be.
