What is addClass() and hasClass() in jQuery?
jQuery addClass() and hasClass()
In jQuery, addClass() and hasClass() are methods used for manipulating and checking CSS classes on HTML elements.
1-addClass() Method:
The addClass() method is used to add one or more classes to the selected elements.
Syntax: $(selector).addClass(className1, className2, ...);
In this example, the addClass() method is used to add the class "highlight" to the paragraph with the ID "myParagraph". This class has a corresponding style in the <style> block that sets the background color to yellow.
2-hasClass() Method:
The hasClass() method is used to check if the selected elements have a specified class.
Syntax: $(selector).hasClass(className);
In this example, the hasClass() method is used to check if the paragraph with the ID "myParagraph" has the class "highlight." The result is then logged to the console.
