.get()
Categories: DOM Element Methods
.get( [ index ] )Returns: Element, Array
Description: Retrieve the DOM elements matched by the jQuery object.
-
.get( [ index ] )
version added: 1.0index A zero-based integer indicating which element to retrieve.
The .get()
method grants us access to the DOM nodes underlying each jQuery object. Suppose we had a simple unordered list on the page:
<ul> <li id="foo">foo</li> <li id="bar">bar</li> </ul>
Without a parameter, .get()
returns all of the elements:
alert($('li').get());
All of the matched DOM nodes are returned by this call, contained in a standard array:
[<li id="foo">, <li id="bar">]
With an index specified, .get() will retrieve a single element:
($('li').get(0));
Since the index is zero-based, the first list item is returned:
<li id="foo">
Each jQuery object also masquerades as an array, so we can use the array dereferencing operator to get at the list item instead:
alert($('li')[0]);
However, this syntax lacks some of the additional capabilities of .get(), such as specifying a negative index:
alert($('li').get(-1));
A negative index is counted from the end of the matched set, so this example will return the last item in the list:
<li id="bar">
-
Selects all divs in the document and returns the DOM Elements as an Array, then uses the built-in reverse-method to reverse that array.
HTML:
Reversed - <span></span> <div>One</div> <div>Two</div> <div>Three</div>
CSS:
span { color:red; }
Code:
function disp(divs) { var a = []; for (var i = 0; i < divs.length; i++) { a.push(divs[i].innerHTML); } $("span").text(a.join(" ")); } disp( $("div").get().reverse() );
-
Gives the tag name of the element clicked on.
HTML:
<span> </span> <p>In this paragraph is an <span>important</span> section</p> <div><input type="text" /></div>
CSS:
span { color:red; } div { background:yellow; }
Code:
$("*", document.body).click(function (e) { e.stopPropagation(); var domEl = $(this).get(0); $("span:first").text("Clicked on - " + domEl.tagName); });
