Quasar is a popular Vue UI library for developing good looking Vue apps.
In this article, we’ll take a look at how to create Vue apps with the Quasar UI library.
Rating Control
We can add a rating control into our Vue app with the Quasarq-rating component.
For instance, we can write:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<q-rating v-model="ratingModel" size="1.5em" icon="thumb_up">
</q-rating>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
ratingModel: 4.5
}
});
</script>
</body>
</html>
We bind the value to display to the ratingModel reactive property with v-model
size sets the size of the icon.
icon sets the name of the icon.
We can set the max rating score with the max prop:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<q-rating v-model="ratingModel" size="2em" :max="10" color="primary">
</q-rating>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
ratingModel: 4.5
}
});
</script>
</body>
</html>
The icon for the rating display can also be an image:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<q-rating
v-model="ratingModel"
size="2em"
color="primary"
icon="img:https://cdn.quasar.dev/logo/svg/quasar-logo.svg"
>
</q-rating>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
ratingModel: 4.5
}
});
</script>
</body>
</html>
We can set an icon to display when the rating icon is selected with the icon-selected prop:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<q-rating
v-model="ratingModel"
size="3.5em"
color="green-5"
icon="star_border"
icon-selected="star"
>
</q-rating>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
ratingModel: 4.5
}
});
</script>
</body>
</html>
We can also set each icon to a different one with the icon prop:
<!DOCTYPE html>
<html>
<head>
<link
href="https://fonts.googleapis.com/css?family=Roboto:100,300,400,500,700,900|Material+Icons"
rel="stylesheet"
type="text/css"
/>
<link
href="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.min.css"
rel="stylesheet"
type="text/css"
/>
</head>
<body class="body--dark">
<script src="https://cdn.jsdelivr.net/npm/vue@^2.0.0/dist/vue.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/quasar@1.12.13/dist/quasar.umd.min.js"></script>
<div id="q-app">
<q-layout
view="lHh Lpr lFf"
container
style="height: 100vh;"
class="shadow-2 rounded-borders"
>
<q-rating
v-model="ratingModel"
size="3.5em"
color="green-5"
:icon="icons"
>
</q-rating>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
ratingModel: 4.5,
icons: [
"sentiment_very_dissatisfied",
"sentiment_dissatisfied",
"sentiment_satisfied",
"sentiment_very_satisfied"
]
}
});
</script>
</body>
</html>
We set icon to an array of icon names.
Conclusion
