The three most basic filtering methods are first(), last() and eq(), which allow you to select a specific element based on its position in a group of elements.
Other filtering methods, like filter() and not() allow you to select elements that match, or do not match, a certain criteria.
The first() method returns the first element of the selected elements.
The following example selects the first <p> element inside the first <div> element:
The last() method returns the last element of the selected elements.
The following example selects the last <p> element inside the last <div> element:
The eq() method returns an element with a specific index number of the selected elements.
The index numbers start at 0, so the first element will have the index number 0 and not 1. The following example selects the second <p> element (index number 1):
The filter() method lets you specify a criteria. Elements that do not match the criteria are removed from the selection, and those that match will be returned.
The following example returns all <p> elements with class name "intro":
The not() method returns all elements that do not match the criteria.
Tip: The not() method is the opposite of filter().
The following example returns all <p> elements that do not have class name "intro":
