Affecting Elements

jQuery has many different methods for affecting elements.

$(".hero-heading").text("Hello");

Gets the current text of an element

let heroHeadingText = $(".hero-heading").text();

.addClass()

Adds a class to an element.

$(".card").addClass("is-active");

Note: period not added before is-active because .addClass already indicates that we're passing in a class name.

.removeClass()

Removes a class from an element

$(".card").removeClass("is-active");

.toggleClass()

Adds a class if that class is not already on the element. Removes a class if that class is already on the element.

$(".card").toggleClass("is-active");

.hasClass()

Returns true or false based on if an element has a certain class

let menuButton = $(".menu-button");

menuButton.on("click", function () {
    menuButton.toggleClass("is-opened");
    if ( menuButton.hasClass("is-opened") ) {
        menuButton.text("Close Menu");
    } else {
        menuButton.text("Open Menu");
    }
});

.val()

let fieldValue = $(".form-field").val();

let cmsList = $(".cms-list");

$(".cta-card").prependTo(".cms-list");

.insertBefore()

Moves the cta-card to be right before the third cms-item

$(".cta-card").insertBefore(".cms-item:nth-child(3)");
