Selector Syntax
Basic CSS selectors
- $("a") - matches all link (<a>) elements
- $("#specialID") - matches elements that have an id of specilID
- $(".specialClass") - matches elements that have the class of specialClass
- $("a#specialID.specialClass") - matches links with an id of specialID and a class of special Class.
- $("p a.specialClass") - matches links with an id of specialID and a class of specialClass
Child, Container, and attribute selectors
- $("p a") - return link elements that are descendents of p tag
- read the selectors backwards
- $("p > a") - return link elements who have a p for a parent element
- $("ul.myList > li > a") - return link elements who are children of a li element, which are in turn children of a ul element of class "myList"
- $("p+a") - matches link elements immediately preceded by sibling p tag
- $("p~a") - matches link elements preceded by any sibling p tag
- $("a[href^=http://]") - return any link elements, the beginning of whose href attribute matches "http://"
- $("form[method]") - return any form element that simply has an explicit method attribute
- $("input[type=text]") - return any input element with a type attribute of text
- $("div[title^=my]") - return any div element whose title attribute starts with "my"
- $("a[href$=.pdf]")
- $("a[href*=jquery.com]")
- $("li:has(a)") - return any li element that has a link element in it
- only one level of nesting supported this way
- $("foo:not(bar:has(baz))") - this is ok
