Jquery insert html after this

.after()

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

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

version added: 1.0 .after( content [, content ] )

HTML string, DOM element, text node, array of elements and text nodes, or jQuery object to insert after each element in the set of matched elements.

One or more additional DOM elements, text nodes, arrays of elements and text nodes, HTML strings, or jQuery objects to insert after each element in the set of matched elements.

version added: 1.4 .after( function )

A function that returns an HTML string, DOM element(s), text node(s), or jQuery object to insert after each element in the set of matched elements. Receives the index position of the element in the set as an argument. Within the function, this refers to the current element in the set.

version added: 1.10-and-2.0 .after( function-html )

A function that returns an HTML string, DOM element(s), text node(s), or jQuery object to insert after 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 .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 content to be inserted comes from the method’s argument: $(target).after(contentToBeInserted) . With .insertAfter() , on the other hand, the content precedes the method and is inserted after the target, which in turn is passed as the .insertAfter() method’s argument: $(contentToBeInserted).insertAfter(target) .

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

Content can be created and then inserted 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>

An element in the DOM can also be selected and inserted after another element:

If an element selected this way is inserted into a single location elsewhere in the DOM, it will be moved rather than cloned:

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

Important: If there is more than one target element, however, cloned copies of the inserted element will be created for each target except for the last one.

Passing a Function

As of jQuery 1.4, .after() supports passing a function that returns the elements to insert.

$( "p" ).after(function( )
return "
" + this.className + "
"
;
>);

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.

Additional Notes:

  • 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.

Examples:

Inserts some HTML after all paragraphs.

jQuery - Add Elements

We will look at four jQuery methods that are used to add new content:

  • append() - Inserts content at the end of the selected elements
  • prepend() - Inserts content at the beginning of the selected elements
  • after() - Inserts content after the selected elements
  • before() - Inserts content before the selected elements

jQuery append() Method

The jQuery append() method inserts content AT THE END of the selected HTML elements.

Example

jQuery prepend() Method

The jQuery prepend() method inserts content AT THE BEGINNING of the selected HTML elements.

Example

Add Several New Elements With append() and prepend()

In both examples above, we have only inserted some text/HTML at the beginning/end of the selected HTML elements.

However, both the append() and prepend() methods can take an infinite number of new elements as parameters. The new elements can be generated with text/HTML (like we have done in the examples above), with jQuery, or with JavaScript code and DOM elements.

In the following example, we create several new elements. The elements are created with text/HTML, jQuery, and JavaScript/DOM. Then we append the new elements to the text with the append() method (this would have worked for prepend() too) :

Example

function appendText() <
var txt1 = "

Text.

"; // Create element with HTML
var txt2 = $(" ").text("Text."); // Create with jQuery
var txt3 = document.createElement("p"); // Create with DOM
txt3.innerHTML = "Text.";
$("body").append(txt1, txt2, txt3); // Append the new elements
>

jQuery after() and before() Methods

The jQuery after() method inserts content AFTER the selected HTML elements.

The jQuery before() method inserts content BEFORE the selected HTML elements.

Example

$("img").before("Some text before");

Add Several New Elements With after() and before()

Also, both the after() and before() methods can take an infinite number of new elements as parameters. The new elements can be generated with text/HTML (like we have done in the example above), with jQuery, or with JavaScript code and DOM elements.

In the following example, we create several new elements. The elements are created with text/HTML, jQuery, and JavaScript/DOM. Then we insert the new elements to the text with the after() method (this would have worked for before() too) :

Example

function afterText() <
var txt1 = "I "; // Create element with HTML
var txt2 = $(" ").text("love "); // Create with jQuery
var txt3 = document.createElement("b"); // Create with DOM
txt3.innerHTML = "jQuery!";
$("img").after(txt1, txt2, txt3); // Insert new elements after
