With jQuery, it is easy to add new elements/content
We will look at four jQuery methods that are used to add new content:
append()
- Inserts content at the end of the selected elementsprepend()
- Inserts content at the beginning of the selected elementsafter()
- Inserts content after the selected elementsbefore()
- Inserts content before the selected elementsThe jQuery append()
method inserts content AT THE END of the selected HTML elements.
$("p").append("Some appended text.");
The jQuery prepend()
method inserts content AT THE BEGINNING of the selected HTML elements.
$("p").prepend("Some prepended text.");
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) :
function appendText()
{
var txt1 = "<p>Text.</p>";
// Create element with HTML
var txt2 = $("<p></p>").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
}
The jQuery after()
method inserts content AFTER the selected HTML elements.
The jQuery before()
method inserts content BEFORE the selected HTML elements.
$("img").after("Some text after");
$("img").before("Some text 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) :
function afterText()
{
var txt1 = "<b>I </b>";
// Create element with HTML
var txt2 = $("<i></i>").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 <img>
}
Use a jQuery method to insert the text "YES!" at the end of a <p> element.
$("p").("YES!");
