What makes jQuery interesting?

• Built around CSS selectors

• Well behaved

• Doesn’t hijack your global namespace

• Plays well with other libraries

• API designed with conciseness and convenience as the driving factors

-------------------------------------------------------------------------------------------------------

The jQuery() function

jQuery('div#intro h2')

jQuery('div.section > p')

jQuery('input:radio')

$('div#intro h2')

--------------------------------------------------------------------------------------------------------

jQuery collections

• $('div.section') returns a jQuery collection

• You can call methods on it:

$('div.section').size() = no. of matched elements

$('div.section').each(function(div) {

// Manipulate the div

}
