Editor to share with you how jQuery gets the content and attributes of HTML elements. I hope you will get something after reading this article. Let's discuss it together.

JQuery-get content and attributes

JQuery has powerful ways to manipulate HTML elements and attributes.

JQuery DOM operation

A very important part of jQuery is the ability to operate DOM.

JQuery provides a series of DOM-related methods that make it easy to access and manipulate elements and attributes.

DOM (document object Model Document Object Model), which defines the criteria for accessing HTML and XML documents:

DOM is platform-independent and language-independent, allowing programs and scripts to dynamically access and update the content, structure, and style of documents.

Get the content-text (), html (), and val ()

Three simple and practical jQuery methods for DOM operations:

Text ()-sets or returns the text content of the selected element

Html ()-sets or returns the contents of the selected element (including the HTML tag)

Val ()-sets or returns the value of the form field

The following example shows how to get content through the jQuery text () and html () methods:

$(document) .ready (function () {$("# btn1") .click (function () {alert ("Text:" + $("# test"). Text ()); $("# btn2") .click (function () {alert ("HTML:" + $("# test"). Html ();}); this is the bold text in the paragraph.

Display text display HTML

The following example shows how to get the value of an input field through the jQuery val () method:

$(document) .ready (function () {$("button") .click (function () {alert ("Value:" + $("# test") .ready ();})

Name:

Display value

Get property-attr ()

The jQuery attr () method is used to get the property value.

The following example shows how to get the value of the href attribute in a link:

$(document) .ready (function () {$("button") .click (function () {alert ($("# w3s"). Attr ("href"));})
