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.
File Input
We can use the q-input component to add a file input.
To do this, we 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"
>
<div class="q-pa-md">
<q-input
@input="val => { file = val[0] }"
filled
type="file"
hint="Native file"
>
</q-input>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
file: undefined
}
});
</script>
</body>
</html>
to add the file input.
We listen to the input event to get the selected files from the val parameter.
The type is set to file to make the input a file input.
Text Area
Setting the type to textarea will make the input a text area:
<!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"
>
<div class="q-pa-md">
<q-input v-model="text" filled type="textarea"> </q-input>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
text: undefined
}
});
</script>
</body>
</html>
The autogrow prop makes the text input automatically grow to fit the text when we enter text:
<!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"
>
<div class="q-pa-md">
<q-input v-model="text" filled autogrow> </q-input>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
text: undefined
}
});
</script>
</body>
</html>
Debounce
The debounce prop makes delays the binding of the input value to the model reactive property:
<!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"
>
<div class="q-pa-md">
<q-input v-model="text" debounce="500" filled placeholder="Search">
</q-input>
<p>{{text}}</p>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
text: undefined
}
});
</script>
</body>
</html>
The denounce duration is in milliseconds.
Input Masks
We can add masked inputs with the q-input component and the mask 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"
>
<div class="q-pa-md">
<q-input
filled
v-model="phone"
label="Phone"
mask="(###) ### - ####"
fill-mask
hint="Mask: (###) ### - ####"
>
</q-input>
</div>
</q-layout>
</div>
<script>
new Vue({
el: "#q-app",
data: {
phone: undefined
}
});
</script>
</body>
</html>
Conclusion
We can add various kinds of input fields into our Vue app with the Quasar v-input component.
