jQuery HTML Methods

jQuery provides several methods to get, set, add, and remove HTML content and attributes.

These make it easy to update a webpage dynamically without writing complex JavaScript.

html() – Get or Set HTML Content

Get: Returns the HTML content of the first matched element.
Set: Replaces the HTML content of all matched elements.

// Get HTML content
let content = $("#demo").html();

// Set HTML content
$("#demo").html("<b>Hello, World!</b>");

text() – Get or Set Text Content

Used to get or change only the text (without HTML tags).

// Get text
let txt = $("p").text();

// Set text
$("p").text("This is new text!");

val() – Get or Set Form Input Value

Used for form elements such as input, textarea, and select.

// Get value
let name = $("#username").val();

// Set value
$("#username").val("John Doe");

append() – Insert Content at the End

Adds new content inside the selected element, after existing content.

$("p").append(" This is appended text.");

prepend() – Insert Content at the Beginning

Adds new content inside, but before existing content.

$("p").prepend("Start: ");

after() – Insert Content After an Element

Inserts content outside the selected element, after it.

$("p").after("<hr>");

before() – Insert Content Before an Element

Inserts content outside the selected element, before it.

$("p").before("<h4>Introduction:</h4>");

remove() – Remove Elements

Deletes the selected elements from the document.

$("#demo").remove();

empty() – Remove Inner Content

Clears the inner HTML content but keeps the element itself.

$("#container").empty();

attr() – Get or Set Attributes

Used to get or change HTML attributes (like src, href, alt, etc.)

// Get attribute
let link = $("a").attr("href");

// Set single attribute
$("a").attr("href", "<https://example.com>");

// Set multiple attributes
$("img").attr({
  "src": "photo.jpg",
  "alt": "Nature Image"
});

removeAttr() – Remove Attribute

Removes an attribute from an element.

$("img").removeAttr("alt");

prop() – Get or Set Properties

Used for DOM properties (like checked, selected, disabled, etc.)

$("#check1").prop("checked", true);
