This section does not seem to have any extracurricular knowledge point, ha, that now enters the topic slightly
1.$ ("Tabname:first")
Description: Can get a node of the first node, such as the example of 6 UL, using $ ("Ul:first") to obtain the first UL node
return value: Element;
2.$ ("Tabname:last")
Description: Similar to previous usage, except that this method is used to get the last node
return value: Element;
3.$ ("Tabname:not (attribute)")
Description: This method enables some simple selector filtering, as in the example, $ ("Input:not (: Checked)") selects the checkbox element that is not selected, and this method is still in practice, as if it can only filter for attributes that have a value of bool. The example is equivalent to selecting checked to false input.
return value: Array (Element);
4.$ ("Tabname:even")
Description: Used to get a set of even index nodes of a node, here to emphasize that the index here is starting from 0 so the example of Aeven click after the acquisition of the 1th, 3, 5 of the UL node
return value: Array (Element);
5.$ ("Tagname:odd")
Description: Like the previous method, the only difference is that this gets a collection of odd-numbered nodes.
return value: Array (Element);
6.$ ("Tagname:eq (Index)")
Description: The node used to get the index position in a node collection
return value: Array (Element);
7.$ ("TAGNAME:GT (Index)")
Description: Used to get a collection of nodes in a node collection with an index greater than index
return value: Array (Element);
8.$ ("Tagname:lt (Index)")
Description: Used to get a collection of nodes in a node collection with an index less than index
return value: Array (Element);
9.$ (": Header")
Description: Used to get a collection of header nodes such as H1, H2, H3 in the page
return value: Array (Element);
