<wa-rating>
Ratings give users a way to quickly view and provide feedback.
<wa-rating label="Rating"></wa-rating>
Ratings are commonly identified contextually, so labels aren't displayed. However, you should always provide
one for assistive devices using the label
attribute.
<wa-rating label="Rate this component"></wa-rating>
Ratings are 0-5 by default. To change the maximum possible value, use the max
attribute.
<wa-rating label="Rating" max="3"></wa-rating>
Use the precision
attribute to let users select fractional ratings.
<wa-rating label="Rating" precision="0.5" value="2.5"></wa-rating>
Set the --symbol-size
custom property to adjust the size.
<wa-rating label="Rating" style="--symbol-size: 2rem;"></wa-rating>
Use the readonly
attribute to display a rating that users can't change.
<wa-rating label="Rating" readonly value="3"></wa-rating>
Use the disabled
attribute to disable the rating.
<wa-rating label="Rating" disabled value="3"></wa-rating>
Use the wa-hover
event to detect when the user hovers over (or touch and drag) the rating. This
lets you hook into values as the user interacts with the rating, but before they select a value.
The event has a payload with phase
and value
properties. The
phase
property tells when hovering starts, moves to a new value, and ends. The
value
property tells what the rating's value would be if the user were to commit to the hovered
value.
<div class="detect-hover"> <wa-rating label="Rating"></wa-rating> <span></span> </div> <script> const rating = document.querySelector('.detect-hover > wa-rating'); const span = rating.nextElementSibling; const terms = ['No rating', 'Terrible', 'Bad', 'OK', 'Good', 'Excellent']; rating.addEventListener('wa-hover', event => { span.textContent = terms[event.detail.value]; // Clear feedback when hovering stops if (event.detail.phase === 'end') { span.textContent = ''; } }); </script> <style> .detect-hover span { position: relative; top: -4px; left: 8px; border-radius: var(--wa-border-radius-s); background: var(--wa-color-neutral-fill-loud); color: var(--wa-color-neutral-on-loud); text-align: center; padding: 4px 6px; } .detect-hover span:empty { display: none; } </style>
You can provide custom icons by passing a function to the getSymbol
property.
<wa-rating label="Rating" class="rating-hearts" style="--symbol-color-active: #ff4136;"></wa-rating> <script type="module"> const rating = document.querySelector('.rating-hearts'); await customElements.whenDefined("wa-rating") await rating.updateComplete rating.getSymbol = () => '<wa-icon name="heart" variant="solid"></wa-icon>'; </script>
You can also use the getSymbol
property to render different icons based on value.
<wa-rating label="Rating" class="rating-emojis"></wa-rating> <script type="module"> const rating = document.querySelector('.rating-emojis'); await customElements.whenDefined("wa-rating") await rating.updateComplete rating.getSymbol = value => { const icons = ['face-angry', 'face-frown', 'face-meh', 'face-smile', 'face-laugh']; return `<wa-icon name="${icons[value - 1]}"></wa-icon>`; }; </script>
