.get()

Categories: DOM Element Methods

.get( [ index ] )Returns: Element, Array

Description: Retrieve the DOM elements matched by the jQuery object.

  • .get( [ index ] )

    version added: 1.0

    index   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>&nbsp;</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);
        });
