Add html element after element jquery

This example inserts a after each paragraph, with each new containing the class name(s) of its preceding paragraph.

Additional Arguments

Similar to other content-adding methods such as .prepend() and .before() , .after() 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 s and an existing after the first paragraph:

var $newdiv1 = $( " " ),
 newdiv2 = document.createElement( "div" ),
 existingdiv1 = document.getElementById( "foo" );
 
$( "p" ).first().after( $newdiv1, [ newdiv2, existingdiv1 ] );

Since .after() can accept any number of additional arguments, the same result can be achieved by passing in the three s as three separate arguments, like so: $( "p" ).first().after( $newdiv1, newdiv2, existingdiv1 ) . The type and number of arguments will largely depend on the elements that are collected in the code.

Дополнительные замечания:

• Prior to jQuery 1.9, .after() would attempt to add or change nodes in the current jQuery set if the first node in the set was not connected to a document, and in those cases return a new jQuery set rather than the original set. The method might or might not have returned a new result depending on the number or connectedness of its arguments! As of jQuery 1.9, .after() , .before() , and .replaceWith() always return the original unmodified set. Attempting to use these methods on a node without a parent has no effect—that is, neither the set nor the nodes it contains are changed.
• By design, any jQuery constructor or method that accepts an HTML string — jQuery(), .append(), .after(), etc. — can potentially execute code. This can occur by injection of script tags or use of HTML attributes that execute code (for example, ). Do not use these methods to insert strings obtained from untrusted sources such as URL query parameters, cookies, or form inputs. Doing so can introduce cross-site-scripting (XSS) vulnerabilities. Remove or escape any user input before adding content to the document.

.insertAfter()

Description: Insert every element in the set of matched elements after the target.

version added: 1.0 .insertAfter( target )

A selector, element, array of elements, HTML string, or jQuery object; the matched set of elements will be inserted after the element(s) specified by this parameter.

The .after() and .insertAfter() methods perform the same task. The major difference is in the syntax—specifically, in the placement of the content and target. With .after() , the selector expression preceding the method is the container after which the content is inserted. With .insertAfter() , 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 after the target container.

Consider the following HTML:

div class="container">
 h2>Greetings h2>
 div class="inner">Hello div>
 div class="inner">Goodbye div>
 div>

We can create content and insert it after several elements at once:

Each inner element gets this new content:

div class="container">
 h2>Greetings h2>
 div class="inner">Hello div>
 p>Test p>
 div class="inner">Goodbye div>
 p>Test p>
 div>

We can also select an element on the page and insert it after another:

$( "h2" ).insertAfter( $( ".container" ) );

If an element selected this way is inserted into a single location elsewhere in the DOM, it will be moved after the target (not cloned) and a new set consisting of the inserted element is returned:

div class="container">
 div class="inner">Hello div>
 div class="inner">Goodbye div>
 div>
h2>Greetings h2>

If there is more than one target element, however, cloned copies of the inserted element will be created for each target after the first, and that new set (the original element plus clones) is returned.

Before jQuery 1.9, the append-to-single-element case did not create a new set, but instead returned the original set which made it difficult to use the .end() method reliably when being used with an unknown number of elements.

Additional Notes:

• By design, any jQuery constructor or method that accepts an HTML string — jQuery(), .append(), .after(), etc. — can potentially execute code. This can occur by injection of script tags or use of HTML attributes that execute code (for example, ). Do not use these methods to insert strings obtained from untrusted sources such as URL query parameters, cookies, or form inputs. Doing so can introduce cross-site-scripting (XSS) vulnerabilities. Remove or escape any user input before adding content to the document.
• jQuery doesn't officially support SVG. Using jQuery methods on SVG documents, unless explicitly documented for that method, might cause unexpected behaviors. Examples of methods that support SVG as of jQuery 3.0 are addClass and removeClass .

Example:

Insert all paragraphs after an element with id of "foo". Same as $( "#foo" ).after( "p" )
