This is what I'm trying to accomplish:
{{ span('Hello') }}
And what desired output should be is:
<span>
Hello
</span>
Is this possible?
Thanks
Look at the below snippet -
Note - You can't render html inside {{ }} because it get added to text node of the element. To render it as an html you need to use v-html and have your function which return element wrapping your text
new Vue({
el: "#app",
data: {
foo: 'asdasd'
},
methods: {
span(text) {
return `<span> ${text} </span>`
}
}
})
span {
color: red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<h1>
Render whatever you want
</h1>
<div v-html="span('Hello world')" />
</div>
<span>{{Hello}}</span>
If you need dynamic HTML tag
<tag :is="tag">{{Hello}}</tag>
Vue.component('tag', {
props:{
is:{type:String, required:true}
},
render(h){
return h(this.tag, this.$slots.default)
}
})
new Vue({
el:'#vue',
data(){
return {
tag:'h1'
}
}
})
For Vue3 it is v-html="htmlContent"

Below is my code in vue.js where I trying to display the out put in list type like. if user give out put in the form of comma separated.
vue.js,angular,react.js
Then I want the out put in this format
vue.js
angular
react.js
This I have implemented in JavaScript but trying to achieve in vue.js please help me to complete this
This is the updated code please tell me where I am going wrong
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/vue#2/dist/vue.js"></script>
</head>
<body>
<div id="demo">
<span v-for="(string, index) in lists">
<span>{{string}}</span><span v-if="index+1 < lists.length">, </span>
</span>
</div>
<script>
var demo = new Vue({
el: '#demo',
data: function() {
return {
string: ''
};
},
computed: {
lists: function(){
return this.string.split(",");
}
}
})
</script>
</body>
</html>
You could use a computed property for this in combination with split:
var demo = new Vue({
el: '#demo',
data: function() {
return {
string: ''
};
},
computed: {
lists: function(){
return this.string.split(",");
}
}
})
I've been searching for the answer 2nd day. But still couldn't find solution.
I have the modal window template. And the main page template from where I need to update modal window size by clicking on the button (span). Shortly it's like this for HTML:
<template id="modal">
<div>
<div :class="'modal-' + size">
...
</div>
</div>
</template>
<template id="list">
<div>
<span #click="onDetails">
Show Details
</span>
</div>
<modal size="md" #showdetails="showdetails();" ref="modal">
...
</modal>
</template>
And for JS:
Vue.component("modal", {
template: "#modal",
props: {
size: {
type: String,
default: ""
}
},
methods: {
onDetails() {
this.$emit("showdetails")
}
}
})
var List = Vue.extend({
template: "#list",
methods: {
showDetails() {
if(this.$refs.modal.size == "md") {
this.$refs.modal.size = "lg"
}
<additional code here>
}
}
})
When I'm accessing this.$refs.modal.size for read - it's OK. When I'm just changing it from showDetails - OK if only this action in the function. When I'm put something else instead of - size is not updating.
For example:
this.$refs.modal.size = "lg" - will work
this.$refs.modal.theme = "danger"; this.$refs.modal.size = "lg" - neither of them are updating
What am I doing wrong?
You need to assign the attribute value of Size by the javascript method setAttribute . Example : this.$refs.modal.setAttribute('size', 'lg')
There is a working demo below:
new Vue({
el: '#app',
methods: {
showdetails() {
console.log(this.$refs.modal.getAttribute('size'));
this.$refs.modal.setAttribute('size', 'lg')
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.15/vue.js"></script>
<div id='app'>
<button size="md" #click="showdetails" ref="modal">Click</button>
</div>
I understand how this works from the VueJS Documentation:
<div id="components-demo">
<button-counter></button-counter>
</div>
And also this:
<div id="app">
<a v-on:click="loadElement(request, etc)">Load</a>
</div>
Is there any way to write the equivalent from a function and have Vue pick it up? For example as this:
<div id="app">
{{ writeComponent('component-name', etc) }}
or
{{ writeElement('loadElement') }} <!-- which then writes the component above -->
</div>
The reason for this is that in this context quite a few components might need to be written and writing it out in HTML would be cumbersome.
You could use the render function like below:
Vue.component('button-counter', {
template: '<span class="bc">bc</span>'
})
new Vue({
el: '#app',
data: {
request: 'req!',
etc: 'etc!',
buttonCounters: []
},
methods: {
loadElement(r, e) {
console.log('loadElement', r, e);
this.buttonCounters.push(r);
}
},
render(h) {
let bcs = this.buttonCounters.map(bc => h('button-counter'));
let loadLink = h('a', {on: {"click": ($event) => { this.loadElement(this.request, this.etc)}}}, ["Load"]);
return h('div', {attrs: {"id": "app"}}, [loadLink, " ", ...bcs])
}
})
<script src="https://unpkg.com/vue"></script>
<div id="app"></div>
Though the same can be achieved via regular template and v-for:
Vue.component('button-counter', {
template: '<span class="bc">bc</span>'
})
new Vue({
el: '#app',
data: {
request: 'req!',
etc: 'etc!',
buttonCounters: []
},
methods: {
loadElement(r, e) {
console.log('loadElement', r, e);
this.buttonCounters.push(r);
}
}
})
<script src="https://unpkg.com/vue"></script>
<div id="app">
<a v-on:click="loadElement(request, etc)">Load</a>
<button-counter v-for="(bc, index) in buttonCounters" :key="index"></button-counter>
</div>
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'm just starting out with VueJS and I was trying to port over a simple jQuery read more plugin I had.
I've got everything working except I don't know how to get access to the contents of the slot. What I would like to do is move some elements passed into the slot to right above the div.readmore__wrapper.
Can this be done simply in the template, or am I going to have to do it some other way?
Here's my component so far...
<template>
<div class="readmore">
<!-- SOME ELEMENTS PASSED TO SLOT TO GO HERE! -->
<div class="readmore__wrapper" :class="{ 'active': open }">
<slot></slot>
</div>
Read {{ open ? lessLabel : moreLabel }}
</div>
</template>
<script>
export default {
name: 'read-more',
data() {
return {
open: false,
moreLabel: 'more',
lessLabel: 'less'
};
},
methods: {
toggle() {
this.open = !this.open;
}
},
}
</script>
You can certainly do what you describe. Manipulating the DOM in a component is typically done in the mounted hook. If you expect the content of the slot to be updated at some point, you might need to do the same thing in the updated hook, although in playing with it, simply having some interpolated content change didn't require it.
new Vue({
el: '#app',
components: {
readMore: {
template: '#read-more-template',
data() {
return {
open: false,
moreLabel: 'more',
lessLabel: 'less'
};
},
methods: {
toggle() {
this.open = !this.open;
}
},
mounted() {
const readmoreEl = this.$el.querySelector('.readmore__wrapper');
const firstEl = readmoreEl.querySelector('*');
this.$el.insertBefore(firstEl, readmoreEl);
}
}
}
});
.readmore__wrapper {
display: none;
}
.readmore__wrapper.active {
display: block;
}
<script src="//cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.min.js"></script>
<div id='app'>
Hi there.
<read-more>
<div>First div inside</div>
<div>Another div of content</div>
</read-more>
</div>
<template id="read-more-template">
<div class="readmore">
<!-- SOME ELEMENTS PASSED TO SLOT TO GO HERE! -->
<div class="readmore__wrapper" :class="{ 'active': open }">
<slot></slot>
</div>
Read {{ open ? lessLabel : moreLabel }}
</div>
</template>
