Events
- change: emitted on (successful) picture change. If you need to access the underlying image from the parent component, add a ref attribute to picture-input (see the example above). You may want to use this.$refs.pictureInput.image (Base64 Data URI string) or this.$refs.pictureInput.file (File Object)
- remove: emitted on picture remove.
- click: emitted on picture click.
Usage
Using some of the options above we can create the following example:
<picture-input
ref="pictureInput"
@change="onChange"
width="500"
height="500"
:removable="true"
:autoToggleAspectRatio="true"
margin="12"
radius="50"
accept="image/jpeg,image/png,image/gif"
size="10"
buttonClass="btn-info"
:customStrings="{
upload: '<h1>Failure!</h1>',
drag: 'Drag a photo here',
selected: '<p>Photo successfully selected!</p>', // HTML allowed
fileSize: 'The file size exceeds the limit', // Text only
fileType: 'This file type is not supported.',
}">
</picture-input>
import PictureInput from 'vue-picture-input'
export default {
name: 'app',
data () {
return {
}
},
components: {
PictureInput
},
methods: {
onChange () {
console.log('New picture selected!')
if (this.$refs.pictureInput.image) {
console.log('Picture loaded.')
} else {
console.log('Not supported!')
}
}
}
}
And there it is, a customized input which accepts images & gifs for uploading, easy and fast.
