How to render div/component in other places in vue? - vue.js

How to render a div/component in other places on my component without make the duplicate content as separate component in vue? or separate the duplicate content from the targets?
for example this is the div I want to duplicate:
<div>blabla {{somecontent}}</div>
and I want to render in those places (all the code should be in one component):
<section>
<div> __HERE__ </div>
</section>
<section>
<div> __HERE__ </div>
</section>
I think want I expect is something like this:
<div #blabla>blabla {{somecontent}}</div>
<section>
<div> {{blabla}} </div>
</section>
<section>
<div> {{blabla}} </div>
</section>

A good solution is creating a Vue component. I always try to create component. AS question demand I give a solution here.
You can create a computed or a method that will render the component like this
<script>
...,
computed: {
renderBlaBla() {
return `<div #blabla>blabla ${this.somecontent}</div>`
}
},
....
</script>
and in the template section
<section>
<div v-html="renderBlaBla"></div>
</section>
<section>
<div v-html="renderBlaBla"></div>
</section>

How to pass in img src in vue.js using props?

I have an info-card.vue component that is used twice in a landing page, but I want different data displayed in each of them. Here is the info-card.vue component:
<template>
<div class="card-container glass-effect">
<div class="illustration-container">
<img src="{{ image }}" alt="Businesses" class="illustration">
</div>
<div class="title-container">{{ title }}</div>
<div class="paragraph-container">{{ content }}</div>
</div>
</template>
<script>
export default {
props: ['image','title', 'content']
}
</script>
And here is the landing-info.vue page that the info-card component is used in:
<div class="business-side">
<info-card image="/images/image1.png" title="BUSINESSES" content="This is some content"></info-card>
</div>
<div class="customer-side">
<info-card image="/images/image2.png" title="CUSTOMERS" content="This is some content"></info-card>
</div>
But this didn't work, I'm new to vue so any ideas?
You can't use mustache {{   }} in vue attributes. Instead use v-bind:attr="" or :attr="" where attr is the dynamic attribute you want to bind.
So, your image component should be:
<img v-bind:src="image" alt="Businesses" class="illustration" />
or
<img :src="image" alt="Businesses" class="illustration">
The colon is a shorthand for v-bind.

How can i pass a parameter to a Vue component?

I just got started to Vue and i'm trying to understand some basic concepts such as conditional rendering and how to pass data from where i load the app to a component. Suppose i'm rendering a Vue component like this:
<div id="app">
<myComponent></myComponent>
</div>
Suppose myComponent looks like this:
<template>
<div>
<h1>First block</h1>
</h1>Second block</h1>
</div>
</template>
I want to be able to render First block or Second block when i load the Vue app according to a parameter i pass to the component, like:
<div id="app">
<myComponent id="first"></myComponent>
</div>
In this case i should see First block, whereas if instead of id="first" there was id="second" the output was supposed to be Second block. How can i do this?
I know it's a very basic question, but most of the sources i found explained how to do the opposite. Any kind of advice is appreciated!
In vue you could pass props (parameters) to component which defines this ones in its script like :
<template>
<div>
<h1 v-if="block==='first'">First block</h1>
</h1 v-else>Second block</h1>
</div>
</template>
<script>
export default{
props:{
block:{
type:String,
default:'first'
}
}
}
</script>
in parent component pass the prop like :
<div id="app">
<myComponent block="first"></myComponent>
</div>
or
<div id="app">
<myComponent block="second"></myComponent>
</div>

VueJS Modal component inside component

I have a component like this:
<test></test>
I declare this as follows:
Vue.component('test', {
data: {
showModal: true
},
methods: {
displayComponentModalDialog: function() {
this.showModal = true;
}
},
template: `<button #click='displayComponentModalDialog'>test</button>`
});
The <test></test> component is then placed somewhere inside the <div id="#app"> wrapper.
var app = new Vue({
router,
el: '#app',
// etc.
})
Now, I want to display another component inside the test component. So in this case I want a dialog to appear after I click the button in test component. I am not able to achieve this.
What I did is adding a new component:
Vue.component('dialog', {
template: '#dialog-template'
});
And then the following code, although I do not know for sure where to put it.
<!-- template for the modal component -->
<script type="text/x-template" id="dialog-template">
<transition name="dialog">
<div class="modal-mask">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
default header
</slot>
</div>
<div class="modal-body">
<slot name="body">
default body
</slot>
</div>
<div class="modal-footer">
<slot name="footer">
<button class="btn btn-primary" #click="$emit('close')">
OK
</button>
</slot>
</div>
</div>
</div>
</div>
</transition>
</script>
<!-- use the modal component, pass in the prop -->
<dialog v-if="showModal" #close="showModal = false">
<h3 slot="header">header</h3>
<p slot="body">
test
</p>
</dialog>
I tried putting this code inside the <test></test> but doesn't work. If I put it inside the template attribute in the component structure, it complains about only one root element.
So it is clear I miss some basic conception how this actually works in VueJS. Someone can help me clarify? Thanks.
As far as I can see your component indeed doesn't have a root tag. Templates have to have a root tag.
This is NOT a valid Vue template:
<div>
<h1>Stuff</h1>
</div>
<h2>Other stuff</h2>
This IS a valid Vue template:
<div>
<div>
<h1>Stuff</h1>
</div>
<h2>Other stuff</h2>
</div>
Note that in the second version we have a single root element for the template, a <div>, whereas in the first one we do not.
You have both a <script></script> and a <dialog></dialog> in your component template.
if you want to add another component in your test component . you can use slot on it.
You can refer to this documentation: https://v2.vuejs.org/v2/guide/components-slots.html
Example:
//component 1
<template>
<div id="modal">
// do something for your modal here.
<slot></slot> // reserve area for your another html or component.
</div>
</template>
// component 2
<template>
<your-modal-component>
<another-component>
</your-modal-component>
</template>

VueJS: Is It Possible to Automatically Include One Component in Another Component

I would like to automatically include the contents of one component in a named slot of another component. I.e., something like this:
Vue.component('comp-one', {
template: `
<div class="comps>
<div class="comp-two">
<slot name="compTwo"></slot>
</div>
<div class="comp-one">
<slot></slot>
</div>
</div>
`
})
Vue.component('comp-two', {
slot: 'compTwo',
template: `
<div class="sub-comp-two">
<!-- content goes here -->
<slot></slot>
</div>
`
})
The idea is that if someone uses <comp-two>Some content</comp-two>, it will automatically get added to the slot compTwo in comp-one. Is there a way to do this?
NOTE: I made up slot: 'compTwo'. Just trying to illustrate what I'd like to accomplish.

Components and Sub components

I'm new to Vue.js and I'm having a bit of trouble using components with sub-components. I have the following .vue files
app.vue
<template>
<section>
<menu></menu>
<h1>Create Your MIA</h1>
<div id="board"></div>
<slider>
<skin></skin>
</slider>
</section>
</template>
slider.vue
<template>
<div id="slider-panel">
<h3>{{* heading}}</h3>
<div class="slider">
<slot>
Some content
</slot>
</div>
</div>
</template>
<script>
import skin from "./skin";
export default {
components: {
skin: skin
}
};
</script>
skin.vue
<template>
<div v-for="colour in colours">
<div :style="{ backgroundColor: colour }">
<img src="../assets/images/MIA.png"/>
</div>
</div>
</template>
<script>
export default {
data() {
return {
heading: "Choose Skin Tone"
};
}
};
</script>
I'm trying to load the skin sub component into the component. Everything works well except for the skin sub component as it doesn't get compiled. I do not get any compile or vue related errors though. I also wanted to be able to have several instances of the slider component like this
app.vue
<template>
<section>
<menu></menu>
<h1>Create Your MIA</h1>
<div id="board"></div>
<slider>
<skin></skin>
</slider>
<slider>
<foo></foo>
</slider>
<slider>
<bar></bar>
</slider>
</section>
</template>
I'm not sure what I am doing wrong.
I'm not 100% sure of what you want to achieve here, but to compile a component inside a component, you need to add the child component inside the parent's template, like this:
Slider.vue (I've simplified the structure):
<template>
<div id="slider-panel">
<h3>{{* heading}}</h3>
<skin></skin>
</div>
</template>
<script>
import skin from './skin'
export default {
components : {
'skin': skin
}
}
</script>
App.vue:
<template>
<section>
<menu></menu>
<h1>Create Your MIA</h1>
<div id="board"></div>
<slider></slider>
</section>
</template>
Actually, if you add skin in the app's template inside of adding it in the slider component template, it gets included (and rendered) assuming that its scope is app, not slider. In order to add skin inside slider scope, it needs to be added to slider's template. Check this: https://vuejs.org/guide/components.html#Compilation-Scope
Some other things:
Use a hyphen-separated name for the components, with at least 2 words: <custom-slider> instead of <slider>, for example, following the Web Components API (otherwise it might collide with current or upcoming web components).
Slots are complicated to grasp, so read this carefully: https://vuejs.org/guide/components.html#Content-Distribution-with-Slots
Good luck!
Update:
If you want the slider component to be content agnostic and be able to insert anything you want inside it, you have two options (that I can think of):
Remove all the logic from the slider component and make skin a descendant from app. Then use slots in the slider component, as follows:
Slider.vue:
<template>
<div id="slider-panel">
<h3>{{* heading}}</h3>
<slot></slot>
</div>
</template>
<script>
export default {}
</script>
App.vue:
<template>
<section>
<menu></menu>
<h1>Create Your MIA</h1>
<div id="board"></div>
<slider>
<skin></skin>
</slider>
</section>
</template>
<script>
import skin from './skin'
export default {
skin: skin
}
</script>
If you know that the slider will always have a closed set of components inside, you can use dynamic components: https://vuejs.org/guide/components.html#Dynamic-Components
After some research I found this which refers to a is= attribute that will transclude the sub-component template
so in app.vue
<slider-component>
<div is="skin-component" v-for="colour in colours"></div>
</slider-component>
and then add child components
