Currently I am using as
<template> ... </template>
<script src="test1.js"> </script>
Where all my business logics are written in test1.js. Now I need to use test2.js with same template. I need to reuse the template with different component.
My current code goes like this...
common.vue
<template>
<div>
{{ page }}
</div>
<template>
<script src="../scripts/test1.js"></script>
Where in test1.js
export default {
name: 'home',
components: {
test: test
},
data() {
return {
page: "test1",
}
}
}
But also i need to use common.vue in my test2.js. Which i am not able to import both the .js seperately.
In angular we can write the fallowing late bindig which binds .html and .js(in ui.router)
.state('home', {
url:'/',
templateUrl: 'templates/home.html',
controller: 'HomeController'
})
Is there something similar to this?
You can share the template through the id attribute.
Vue.component('my-comp1', {
template: '#generic',
data () {
return {
text: 'I am component 1'
}
}
})
Vue.component('my-comp2', {
template: '#generic',
data () {
return {
text: 'I am component 2'
}
}
})
new Vue({
el: '#app'
})
<div id="app">
<my-comp1></my-comp1>
<my-comp2></my-comp2>
</div>
<template id="generic">
<div>
<p>{{ text }}</p>
</div>
</template>
<script src="https://unpkg.com/vue"></script>

I have the following Vue component called TeamCard:
<template>
<div class="m-8 max-w-sm rounded overflow-hidden shadow-lg">
<!-- removed fro brevety -->
div class="text-gray-900 font-bold text-xl mb-2">{{ name }}</div>
<p class="text-gray-700 text-base"> {{ description }} </p>
<!-- removed fro brevety -->
</div>
</div>
</template>
<script>
export default {
name: "TeamCard",
props: {
name: {
type: String,
required: true,
},
description: {
type: String,
required: true,
},
}
};
</script>
<style scoped>
#import "https://unpkg.com/tailwindcss#^2/dist/tailwind.min.css";
</style>
I call the component in an HTML page (Spring boot template) the following way:
<teamCard v-bind:name="'Hawks'" v-bind:description="'Best team'" ></teamCard>
<script src="https://unpkg.com/vue"></script>
<script th:src="#{/TeamCard/TeamCard.umd.min.js}"></script>
<script>
(function() {
new Vue({
components: {
teamCard: TeamCard
}
})
})();
</script>
When I go to the page in the browser that has the second snippet, nothing is shown. There are no errors in the console. What am I doing wrong? How can I make the component be shown?
I've never seen Vue used this way but it looks like there is no mounting element for the app. Try this:
<div id="app">
<team-card v-bind:name="'Hawks'" v-bind:description="'Best team'"></team-card>
</div>
and
(function() {
new Vue({
el: '#app',
components: {
teamCard: TeamCard
}
})
})();
I'm new to Vue and have been trying to figure this out for days without finding a solution that works...
How do I add an external vue-component multiple times #click on button?
Hopefully my pseudo-code below will explain what i'm trying to do.
<template>
<div>
<Piece/>
<!-- HERE I WANT TO ADD MULTIPLE "<Piece/>" #click on below button -->
<button type="button" #click="addPiece">Add Piece</button>
</div>
</template>
<script>
import Piece from "#/components/Piece.vue";
export default {
name: "PiecesModal",
components: {
Piece,
},
methods: {
addPiece () {
this.components.push(Piece)
}
},
};
</script>
Vue is "data driven"
Instead of wasting time "figuring this out for days", just read the excellent docs, List Rendering in this case...
const piece = Vue.component('Piece', {
props: ['number'],
template: `<div> Piece {{ number }} </div>`
})
const app = new Vue({
el: "#app",
components: { piece },
data() {
return {
counter: 0,
pieces: []
}
},
methods: {
addPiece() {
this.pieces.push(this.counter)
this.counter++
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<button type="button" #click="addPiece">Add Piece</button>
<hr>
<Piece v-for="piece in pieces" :key="piece" :number="piece"/>
</div>
As answered here, we can check if a slot has content or not. But I am using a slot which has no name:
<template>
<div id="map" v-if="!isValueNull">
<div id="map-key">{{ name }}</div>
<div id="map-value">
<slot></slot>
</div>
</div>
</template>
<script>
export default {
props: {
name: {type: String, default: null}
},
computed: {
isValueNull() {
console.log(this.$slots)
return false;
}
}
}
</script>
I am using like this:
<my-map name="someName">{{someValue}}</my-map>
How can I not show the component when it has no value?
All slots have a name. If you don't give it a name explicitly then it'll be called default.
So you can check for $slots.default.
A word of caution though. $slots is not reactive, so when it changes it won't invalidate any computed properties that use it. However, it will trigger a re-rendering of the component, so if you use it directly in the template or via a method it should work fine.
Here's an example to illustrate that the caching of computed properties is not invalidated when the slot's contents change.
const child = {
template: `
<div>
<div>computedHasSlotContent: {{ computedHasSlotContent }}</div>
<div>methodHasSlotContent: {{ methodHasSlotContent() }}</div>
<slot></slot>
</div>
`,
computed: {
computedHasSlotContent () {
return !!this.$slots.default
}
},
methods: {
methodHasSlotContent () {
return !!this.$slots.default
}
}
}
new Vue({
components: {
child
},
el: '#app',
data () {
return {
show: true
}
}
})
<script src="https://unpkg.com/vue#2.6.10/dist/vue.js"></script>
<div id="app">
<button #click="show = !show">Toggle</button>
<child>
<p v-if="show">Child text</p>
</child>
</div>
Why you dont pass that value as prop to map component.
<my-map :someValue="someValue" name="someName">{{someValue}}</my-map>
and in my-map add prop:
props: {
someValue:{default: null},
},
So now you just check if someValue is null:
<div id="map" v-if="!someValue">
...
</div
i have these components:
<template id="test-button-component">
<div class="test-button__container">
This is test button
<button #click="clickButton">{{buttonTitle}}</button>
</div>
</template>
<template id="test-button-component2">
<div class="test-button__container">
<button></button>
</div>
</template>
I try to use the Vue's :is binding to do a component binding by name as follow:
<div :is='myComponentName' ></div>
every time the myComponentName changed to other component, the new component will replace the old component. The thing i need is, is there any way i can get the instance of the component so i can get the view model instance of the currently bound component?
You can add a ref attribute (for example ref="custom") to the <div> tag for the dynamic component. And then reference the component instance via this.$refs.custom.
Here's a simple example where the data of the component gets logged whenever the value being bound to the is prop is changed:
new Vue({
el: '#app',
data() {
return {
value: 'foo',
children: {
foo: {
name: 'foo',
template: '<div>foo</div>',
data() {
return { value: 1 };
}
},
bar: {
name: 'bar',
template: '<div>bar</div>',
data() {
return { value: 2 };
}
}
}
}
},
computed: {
custom() {
return this.children[this.value];
}
},
watch: {
custom() {
this.$nextTick(() => {
console.log(this.$refs.custom.$data)
});
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.min.js"></script>
<div id="app">
<select v-model="value">
<option>foo</option>
<option>bar</option>
</select>
<div :is="custom" ref="custom"></div>
</div>
Note that the $data for the component reference by $refs.custom is getting logged inside of a $nextTick handler. This is because the bound component won't update until the parent view has re-rendered.
Is it possible to declare a component inside another component in Vue.JS?
this is what i'm trying to do:
<!-- this is declared inside some-component.vue file -->
<script>
export default {
components:{
'cmptest' : {
template:'#cmptest',
props:['mprop']
}
},
data : () => ({
val:'world'
})
};
</script>
<template>
<div>
<template id="cmptest">
{{mprop}}
</template>
<cmptest mprop="hello"></cmptest>
<cmptest :mprop="val"></cmptest>
</div>
</template>
I'd like to avoid globally registering the child component if possible (with Vue.component(...))
In other words, I'd like to specify child's <template> inside the parent component file (without doing a huge line template:'entire-html-of-child-component-here')
Sure.
Like this:
https://jsfiddle.net/wostex/63t082p2/7/
<div id="app">
<app-child myprop="You"></app-child>
<app-child myprop="Me"></app-child>
<app-child myprop="World"></app-child>
</div>
<script type="text/x-template" id="app-child2">
<span style="color: red">{{ text }}</span>
</script>
<script type="text/x-template" id="app-child">
<div>{{ childData }} {{ myprop }} <app-child2 text="Again"></app-child2></div>
</script>
new Vue({
el: '#app',
components: {
'app-child': {
template: '#app-child',
props: ['myprop'],
data: function() {
return {
childData: 'Hello'
}
},
components: {
'app-child2': {
template: '#app-child2',
props: ['text']
}
}
}
}
});
