How can I implement displaying a link in a primevue toast message? I cannot use v-html directive and triple brackets do not work. Does anybody has another idea how to solve it?
A hacky way is to extends Toast component:
Here a codesandbox : https://codesandbox.io/s/extend-primevue-toast-o5o1c?file=/src/CustomToastMessage.vue
1. On your component
Import your custom toast component where you need to call this.$toast:
<template>
<div>
<CustomToast />
<CustomToast position="top-left" group="tl" />
<CustomToast position="bottom-left" group="bl" />
<CustomToast position="bottom-right" group="br" />
<div class="card">
<Button #click="test" label="test" />
</div>
</div>
</template>
<script>
import CustomToast from "./CustomToast.vue";
export default {
components: {
CustomToast,
},
data() {
return {
messages: [],
};
},
methods: {
test() {
this.$toast.add({
severity: "success",
summary: "Test",
detail: "<b>Test Bold</b>",
});
},
},
};
</script>
2. CustomToast.vue (extend primevue toast)
<template>
<Teleport to="body">
<div ref="container" :class="containerClass" v-bind="$attrs">
<transition-group name="p-toast-message" tag="div" #enter="onEnter">
<CustomToastMessage
v-for="msg of messages"
:key="msg.id"
:message="msg"
#close="remove($event)"
/>
</transition-group>
</div>
</Teleport>
</template>
<script>
import Toast from "primevue/toast/Toast.vue";
import CustomToastMessage from "./CustomToastMessage.vue";
export default {
extends: Toast,
components: {
CustomToastMessage,
},
};
</script>
3. CustomToastMessage (extend primevue toastmessage)
Add v-html where you want to have html
<template>
<div
:class="containerClass"
role="alert"
aria-live="assertive"
aria-atomic="true"
>
<div class="p-toast-message-content">
<span :class="iconClass"></span>
<div class="p-toast-message-text">
<span class="p-toast-summary">{{ message.summary }}</span>
<div class="p-toast-detail" v-html="message.detail"></div>
</div>
<button
class="p-toast-icon-close p-link"
#click="onCloseClick"
v-if="message.closable !== false"
type="button"
v-ripple
>
<span class="p-toast-icon-close-icon pi pi-times"></span>
</button>
</div>
</div>
</template>
<script>
import ToastMessage from "primevue/toast/ToastMessage.vue";
export default {
extends: ToastMessage,
};
</script>
There is an easiest solution.
Just implement your own template.
Example:
<Toast :position="toastPosition">
<template #message="slotProps">
<span :class="iconClass"></span>
<div class="p-toast-message-text">
<span class="p-toast-summary">{{slotProps.message.summary}}</span>
<div class="p-toast-detail" v-html="slotProps.message.detail" />
</div>
</template>
</Toast>
In the HeaderComponent method 'clickPrices' is called on click
<template>
<header>
<div class="d-flex flex-column flex-md-row align-items-center p-3 px-md-4 mb-3 bg-white border-bottom shadow-sm">
<h5 class="my-0 mr-md-auto font-weight-normal">Company name</h5>
<nav class="my-2 my-md-0 mr-md-3">
<a class="p-2 text-dark" href="#">Features</a>
<a class="p-2 text-dark">Enterprise</a>
<a class="p-2 text-dark" #click="clickPrices()">Get pricing</a>
</nav>
<a class="btn btn-outline-primary " href="#">Sign up</a>
</div>
</header>
</template>
<script>
export default {
name: "HeaderComponent",
methods: {
clickPrices() {
...
},
},
}
</script>
<style scoped>
</style>
and there is a Pricing Component in which I make a request to the server in the method 'getPricing'
<template>
<div class="wrap-pricing">
<div class="pricing-header px-3 py-3 pt-md-5 pb-md-4 mx-auto text-center">
<h1 class="display-4">Pricing</h1>
<p class="lead">Quickly build an effective pricing table for your potential customers with this Bootstrap example. It’s built with default Bootstrap components and utilities with little customization.</p>
</div>
<div class="container">
<div class="card-deck mb-3 text-center">
<div class="card mb-4 shadow-sm">
<div class="card-header">
<h4 class="my-0 font-weight-normal">Lorem</h4>
</div>
<div class="card-body">
<h1 class="card-title pricing-card-title">$10 <small class="text-muted">/ mo</small></h1>
<ul class="list-unstyled mt-3 mb-4">
<li>Lorem</li>
<li>Lorem</li>
<li>Lorem</li>
<li>Lorem</li>
</ul>
<button type="button" class="btn btn-lg btn-block"></button>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import router from '../routes.js';
import { axios } from 'axios';
export default {
name: "PriceComponent",
methods: {
getPricing() {
axios.get('api/pricing').then((response) => {
//some actions
router.push('prices');
});
},
},
}
</script>
<style scoped>
</style>
How should I process the result of the 'сlickPrices' HeaderComponent method?
Or am I waiting for your ways, how can I get data in another by clicking in one component
You can emit an event and let the parent component handle the fetching and pass the data as props to the child component.
Or another way is to directly listen to the event as follows
Component 1:
this.$root.$emit('clickPrices', data);
Component 2:
mounted() {
this.$root.$on('clickPrices', data => {
this.getPricing();
});
}
Check out the answer by #alex
Since you are using 2 independent components (one is not included in the other), you cannot pass props
Things you can do -
Instead of fetching all the prices on click, just create a created hook like so, which will fetch all the pricing details whenever your component is created -
created () {
this.getPricing()
},
methods: {
getPricing() {
axios.get('api/pricing').then((response) => {
//some actions
router.push('prices');
});
},
},
Use State and when a user clicks on the button, pricing details are fetched and added in the state. And you can just use the state anywhere in your application like so -
this.$store.state.prices
Let me know if it works, if not we will find some other solution for you!
Sorry for the help request, but I can't work out how to get a bootstrap-vue modal to display initially on page load without needing to trigger it with a button or link.
Thanks.
Instead of trying to open modal on page load, you can open it on mounted event of Vue.
Elevated from sample code on Bootstrap-Vue website:
<template>
<div>
<b-modal ref="my-modal" hide-footer title="Using Component Methods">
<div class="d-block text-center">
<h3>Hello From My Modal!</h3>
</div>
<b-button class="mt-3" variant="outline-danger" block #click="hideModal">Close Me</b-button>
<b-button class="mt-2" variant="outline-warning" block #click="toggleModal">Toggle Me</b-button>
</b-modal>
</div>
</template>
<script>
export default {
methods: {
showModal() {
this.$refs['my-modal'].show()
},
hideModal() {
this.$refs['my-modal'].hide()
}
},
mounted() {
this.showModal();
}
}
</script>
How can I use the #onerror event in b-card of Bootstrap Vue?
I would like to handle the 404 of image so that I can display a default image.
<b-card overlay
:title="name"
:sub-title="description"
:img-src="cardImg"
img-top
style="max-width: 20rem;"
class="mb-2">
</b-card>
I would recommend placing a <b-img-lazy> component inside of a <b-card> with the no-body prop set.
<b-card no-body>
<b-img-lazy class="card-img-top" src="...." #error.native="onError" />
<b-card-body :title="name" :sub-title="description">
Card Text
</b-card-body>
</b-card>
For reference on the above components, see:
https://bootstrap-vue.js.org/docs/components/card#kitchen-sink-example
https://bootstrap-vue.js.org/docs/components/image
Well, this component doesn't seem to provide this particular event handler (at the time of writing), but you could add a ref on the component and register the error handler on mounted hook:
<b-card overlay
:title="name"
:sub-title="description"
:img-src="cardImg"
img-top
style="max-width: 20rem;"
class="mb-2"
ref="card">
</b-card>
new Vue({
el: '#app',
mounted() {
this.$refs.card.querySelector('img').onerror = this.handleImgError;
},
methods: {
handleImgError(evt) {
// event has all the error info you will need
// evt.type = 'error';
}
}
});
Or actually, create a wrapper component providing one.
./components/Card.vue
<template>
<b-card
overlay
:title="name"
:sub-title="description"
:img-src="cardImg"
img-top
style="max-width: 20rem;"
class="mb-2">
</b-card>
</template>
<script>
import bCard from "bootstrap-vue/es/components/card/card";
export default {
name: "Card",
mounted() {
this.$el.querySelector("img").onerror = e => {
this.$emit('onerror', e);
};
},
components: {
bCard
}
};
</script>
index.html
<div id="app">
<card #onerror="handleImgError"></card>
</div>
VueJS component doesn't get cached or atleast reattached after navigation. On refresh or launch everything gets attached and rendered well but after navigating to another page then back. The First Component - Carousel - component in my case doesn't get rendered but the API call is made.
<template>
<div class="rel">
<div id="homeCarousel" class="owl-carousel owl-slider">
<div class="item" v-for="product in featured">
<div class="bg-holder top-area-half" >
<div class="bg-mask-lighten"></div>
<img class="bg-img" v-bind:src="product.feature_image_url">
<div class="hero-caption">
<div class="container">
<h3 class="hero-title">{{product.feature_title}}</h3>
<p class="hero-subtitle">{{product.feature_subtitle}}</p>
<a class="btn btn-white btn-ghost btn-lg hero-btn" href="#">Shop now</a>
</div>
</div>
</div>
</div>
</div>
<div id="hero-slider-nav" class="hero-slider-nav">
<div class="container">
<div class="pull-right"></div>
</div>
</div>
</div>
</template>
<style>
</style>
<script>
export default{
data(){
return{
featured:[]
}
},
ready(){
},
mounted(){
this.getFeaturedProducts();
},
components:{
},
methods: {
getFeaturedProducts: function () {
Vue.http.get('/api/product/filter/featured=1').then(
(response) => {
this.featured = response.body;
}
)
}
}
}
</script>
`
<template>
<div class="global-wrapper clearfix ">
<keep-alive>
<Carousel></Carousel>
</keep-alive>
//The rest of the code which is just importing the Component
I found out what i was doing wrong. I had a separate JS/JQuery file and on the document ready i was initializing an owl carousel by id #('homeCarousel').owlCarousel({}) . What worked was, since i had already bootstrapped owl carousel -> on the mounted lifecycle callback i was now targeting the element and making it an owl carousel.
