so on this project i was trying to make an image component to display an image from a string props.
here is my component code
this is the component
<template>
<div class="Img-grid">
<div class="container">
<div class="col">
<img :v-bind:src="recipeImage" alt="image-photo">
<p>{{recipeName}}</p>
</div>
</div>
</div>
</template>
<script>
export default {
name: 'ImgGrd'
props: {
recipeImage: String,
recipeName: String
}
}
</script>
this is my where the component display
<template>
<div class="RecipeByYou">
<div class="container">
<ImgGrid recipeName="a" v-bind:recipeImage="imgUrl" />
</div>
</div>
</template>
<script>
import ImgGrid from '../components/Image_Grid.vue'
export default {
name: 'RecipeImage',
components: {
Header,
ImgGrid
},
data () {
return {
imgUrl: 'https://media.sproutsocial.com/uploads/2017/02/10x-featured-social-media-image-size.png'
}
}
}
am i doing anything wrong? because when i inspect the web element it shows this thing, so i was confuse where did i do wrong, is this the correct method?
<img data-v-366ed4fa="" v-bind:src="https://media.sproutsocial.com/uploads/2017/02/10x-featured-social-media-image-size.png" alt="image-photo">
change this code <img :v-bind:src="recipeImage" alt="image-photo"> to <img v-bind:src="recipeImage" alt="image-photo">.
or you can change <img :v-bind:src="recipeImage" alt="image-photo"> to <img :src="recipeImage" alt="image-photo">.
: is shorthand of v-bind, your code :v-bind:src="recipeImage" means v-bind:v-bind:src="recipeImage"

Is there any Jquery's html() function for vue?

Im super new to Vue.
i have a Vue-CLI app, which have a navbar and content.
Navbar is common to all pages, but i want to customize in each page whit some additional content.
Example:
Common-> home | about
View home -> home | about | your are in view home
View about -> home | about | your are in view about
router/index.js
import Vue from 'vue';
import VueRouter from 'vue-router';
import Home from '../views/Home.vue';
import NavBar from '#/components/NavBar.vue';
Vue.use(VueRouter);
Vue.component('nav-bar', NavBar);
//...
components/navbar.vue
<template>
<div>
<b-nav-item to="/">home</b-nav-item>
<b-nav-item to="/about">about</b-nav-item>
{{customContent}}
</div>
</template>
<script>
export default {
name: 'NavBar',
props: {
customContent: {
type: String,
default: 'default Content',
},
},
};
</script>
App.vue
<template>
<div id="app">

views/home.vue
<template>
<div class="row">

<image-card :images="images"/>
</div>
</div>
</template>
<script>
//how can i customize here the navbar by adding for example 'your are in view home'???
</script>
Thanks so much!
There are a few ways in which you can solve this problem. I'll list two of them.
1. Update NavBar by $route
In this approach, the NavBar component already contains all of the possible combinations, and will display the relevant portion(s) depending on what $route contains.
Here's some pseudo code:
navbar.vue
<template>
<div class="navbar">
<div class="navbar-left>
APPNAME
</div>
<div v-if="name === 'landing'">
...
</div>
<div v-else-if="name === 'room'">
...
</div>
</div>
</template>
App.vue
<template>
<div id="app">
<NavBar :name="$route.name"/>
<main>
<router-view/>
</main>
</div>
</template>
In this example, the NavBar component is very rigid, and doesn't really lend itself to much reuse. However, it does encapsulate all the relevant code relating to the nav bar.
2. Extensible NavBar with slots
In this approach, the NavBar only provides the bare-minimum to create a nav bar. The rest of the route-specific elements are to be filled in by the views.
navbar.vue
<template>
<div class="navbar">
<div class="navbar-left">
<div class="navbar-brand">
APPNAME
</div>
<slot name="left"></slot>
</div>
<div class="navbar-right">
<slot name="right"></slot>
</div>
</div>
</template>
App.vue
<template>
<div id="app">
<router-view/>
</div>
</template>
landing.vue
<template>
<div>
<header>
<NavBar>
<template slot="right">
<span>
<div class="navbar-item">
<div class="buttons">
<button class="button" #click="...">Start Watching</button>
</div>
</div>
</span>
</template>
</NavBar>
</header>
<main>
...
</main>
</div>
</template>
This approach has a bit of repetition in terms of DOM elements, but gives you an extremely flexible NavBar that can be customized by each view.
The approach you want to use depends on what is important to you.
If strict encapsulation is what you want, then you may want to use approach 1, as all of the NavBar-related code is contained within a single file.
However, if you believe that there is a potential for reuse, or if you would like all view-related code to live in one place, then it makes sense to use slots instead and extend the NavBar as required by each view.
I use a breadcrumb to achieve a similar thing. Just an idea but Vue router allows you to add meta data to the current route which you always have access to
router.js
path: '/add',
name: 'add',
component: () => import(/* webpackChunkName: "add" */ '../../views/Add.vue'),
meta: {
breadCrumb: [
{ name: 'Add New' }
]
},
Notice the meta object attached to the route.. this will be used to describe the current view.
Breadcrumb.vue component
<template>
<div class="breadcrumb">
<ul class="d-flex m-0 p-0"
<li
v-for="(breadcrumb, idx) in breadcrumbList"
:key="idx">
{{ breadcrumb.name }}
</li>
</ul>
</div>
</template>
<script>
export default {
name: 'Breadcrumb',
data () {
return {
breadcrumbList: []
}
},
mounted () { this.updateList() },
watch: { '$route' () { this.updateList() } },
methods: {
routeTo (pRouteTo) {
if (this.breadcrumbList[pRouteTo].link) this.$router.push(this.breadcrumbList[pRouteTo].link)
},
updateList () { this.breadcrumbList = this.$route.meta.breadCrumb },
formatPath(path) {
const newPath = path.replace(/\//g, " > ")
return newPath
}
}
}
</script>
And then you can import the breadcrumb into your navbar or where ever you would like to place it
<Breadcrumb class="breadcrumb" />
import Breadcrumb from '#/components/Breadcrumb.vue'
components: {Breadcrumb}
So basically the breadcrumb will always watch your current route and change the data based on the meta data you provide in your router.js file
You can access to router name like this:
<div v-if="this.$route.name == 'home'">
<HeaderTransparent />
</div>
<div v-else>
<HeaderWhite />
</div>
In a laravel 5.4 environment I want to render the text "Example" in the .panel-heading of Example.vue. After doing npm run watch I get the following Vue warn:
'Property or method "message" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.'
app.js
require('./bootstrap');
window.Vue = require('vue');
Vue.component('example', require('./components/Example.vue'));
const app = new Vue({
el: '#app',
data: {
message: 'Example'
}
});
Example.vue
<template>
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading" >{{ message }}</div>
<div class="panel-body">
I'm an example component!
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
console.log('Component mounted.')
}
}
</script>
app.blade.php
<html>
<!-- ... -->
<body>
<div id="app">
<example></example>
</div>
<script src="{{ asset('js/app.js') }}"></script>
</body>
</html>
Your Example.vue component doesn't have access to its parent's properties. You need to define message within the same scope of the component you are trying to use it in.
You can do this by adding message as a data property in your Example component:
// Example.vue script
export default {
data() {
return {
message: 'Example',
}
},
}
Or you can pass it in as a prop:
// Example.vue script
export default {
props: ['message'],
}
In your case, you would pass a value for the message prop like this:
// in app.blade.php
<example message="Example"></example>
Here's the documentation on Vue Component props.
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.
