What’s the equivalent of ‘getElementsByTagName’ in jQuery?

$("tagnamehere")

So:

$("div").each(function() {
    // do something exciting with each div
    $(this).css("border", "1px solid red");

    // do something by directly manipulating the wrapped DOM element
    this.style.border = "1px solid red";

    // do something only if this particular div has a class of 'pretty'
    if($(this).hasClass("pretty")) {
        $(this).text("I am the pretty one");
    }
});

or just:

// apply some css to all div elements
$("div").css("border", "1px solid red");

Keep in mind that when you use jQuery to select a number of elements, e.g. $("span"), any method you invoke on the object will happen on all matched elements. Think of it as ‘implicit iteration’ – e.g. $("span").hide(); will hide all span elements on the page.
