jQuery Filtering

This lesson is part of jQuery · All levels

Summary

Filtering is used to filter selection results so that only certain elements are processed. Methods such as first(), last(), eq(n), filter(), and not() narrow down the selection from the existing set. With filtering you can take the first item, the numbered item, or just the one that qualifies without writing a new selector.

Key points

First() and last() take the first and last elements of the selection results
Eq(n) takes the element based on the index number starting from zero
Filters elements that match the selector or function
Excludes elements that match the selector
Checks whether selection produces a particular element
