Categories: Manipulation > DOM Insertion, Inside

.append( content [, content ] ) Returns: jQuery

Description: Insert content, specified by the parameter, to the end of each element in the set of matched elements.

  • version added: 1.0.append( content [, content ] )

    • content
      Type: htmlString or Element or jQuery
      DOM element, HTML string, or jQuery object to insert at the end of each element in the set of matched elements.
    • content
      Type: htmlString or Element or Array or jQuery
      One or more additional DOM elements, arrays of elements, HTML strings, or jQuery objects to insert at the end of each element in the set of matched elements.

  • version added: 1.4.append( function(index, html) )

    • function(index, html)
      Type: Function()
      A function that returns an HTML string, DOM element(s), or jQuery object to insert at the end of each element in the set of matched elements. Receives the index position of the element in the set and the old HTML value of the element as arguments. Within the function, this refers to the current element in the set.

The .append() method inserts the specified content as the last child of each element in the jQuery collection (To insert it as the first child, use .prepend()).

The .append() and .appendTo() methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target. With .append(), the selector expression preceding the method is the container into which the content is inserted. With .appendTo(), on the other hand, the content precedes the method, either as a selector expression or as markup created on the fly, and it is inserted into the target container.

Consider the following HTML:

                                    <h2>Greetings</h2>
                                  

                                

                                

                                  

                                    
                                      <div class="container">
                                    
                                  

                                

                                

                                  

                                      <div class="inner">Hello</div>
                                  

                                

                                

                                  

                                      <div class="inner">Goodbye</div>
                                  

                                

                                

                                  

                                    
                                      </div>

You can create content and insert it into several elements at once:

1
 
                                

                                  

                                    $('.inner').append('<p>Test</p>');

Each inner <div> element gets this new content:

                                    <h2>Greetings</h2>
                                  

                                

                                

                                  

                                    
                                      <div class="container">
                                    
                                  

                                

                                

                                  

                                      <div class="inner">
                                  

                                

                                

                                  

                                        Hello
                                  

                                

                                

                                  

                                        <p>Test</p>
                                  

                                

                                

                                  

                                      </div>
                                  

                                

                                

                                  

                                      <div class="inner">
                                  

                                

                                

                                  

                                        Goodbye
                                  

                                

                                

                                  

                                        <p>Test</p>
                                  

                                

                                

                                  

                                      </div>
                                  

                                

                                

                                  

                                    
                                      </div>

You can also select an element on the page and insert it into another:

1
 
                                

                                  

                                    $('.container').append($('h2'));

If an element selected this way is inserted into a single location elsewhere in the DOM, it will be moved into the target (not cloned):

                                      <div class="container">
                                    
                                  

                                

                                

                                  

                                      <div class="inner">Hello</div>
                                  

                                

                                

                                  

                                      <div class="inner">Goodbye</div>
                                  

                                

                                

                                  

                                      <h2>Greetings</h2>
                                  

                                

                                

                                  

                                    
                                      </div>

If there is more than one target element, however, cloned copies of the inserted element will be created for each target after the first.

Additional Arguments

Similar to other content-adding methods such as .prepend() and .before(), .append() also supports passing in multiple arguments as input. Supported input includes DOM elements, jQuery objects, HTML strings, and arrays of DOM elements.

For example, the following will insert two new <div>s and an existing <div> as the last three child nodes of the body:

                                    var $newdiv1 = $('<div id="object1"/>'),
                                  

                                

                                

                                  

                                        newdiv2 = document.createElement('div'),
                                  

                                

                                

                                  

                                        existingdiv1 = document.getElementById('foo');
                                  

                                

                                

                                  

                                     
                                  

                                

                                

                                  

                                    $('body').append($newdiv1, [newdiv2, existingdiv1]);

Since .append() can accept any number of additional arguments, the same result can be achieved by passing in the three <div>s as three separate arguments, like so: $('body').append($newdiv1, newdiv2, existingdiv1). The type and number of arguments will largely depend on how you collect the elements in your code.
