Here is my Html code.
<div id="app">
<button #click="renderHtml">clisdfsdfsdfck to appen html</button>
<div class="flex">
<div class="message" #input="fakeVmodel" v-html="html" contenteditable="true"></div>
<div class="message">{{ html }}</div>
</div>
</div>
Here is js part
let app = new Vue({
el: '#app',
data: {
html: 'some text',
},
methods: {
fakeVmodel: function(e){
this.html = e.target.innerText;
},
renderHtml: function(){
this.html += '<img src="https://cdn-images-1.medium.com/max/853/1*FH12a2fX61aHOn39pff9vA.jpeg" alt="" width=200px>';
}
}
});
The problem is, when I click the button to push a html tag(img) to my variable (html) and it works. but after typing, it will remove the tag part that was insert. Is that any way to append to html code successful in Vue?
Here is the codepen example
https://codepen.io/weretyc/pen/EwXZYL?editors=1010
The main problem:
The html disappears because of this.html = e.target.innerText;. Instead, use this.html = e.target.innerHTML;. innerHTML resolves to the full HTML content.
Secondary Problem:
After typing, the cursor focuses the beginning of the div. This is because v-html causes the div to update.
To solve, ensure that v-html only updates the div on focusout.
Full Example
let app = new Vue({
el: '#app',
data: {
html: 'some text',
},
methods: {
updateHtml: function(e) {
this.html = e.target.innerHTML;
},
renderHtml: function(){
this.html += '<img src="https://cdn-images-1.medium.com/max/853/1*FH12a2fX61aHOn39pff9vA.jpeg" alt="" width=200px>';
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.4/vue.js"></script>
<div id="app">
<button #click="renderHtml">click to append html</button>
<div class="flex">
<div class="message" #focusout="updateHtml" v-html="html" contenteditable="true"></div>
<br>
<div class="message">{{ html }}</div>
</div>
</div>

I need to convert some code to Vue, I have a rendering difference in the alt attribute of an image, because I can't find a way to interpret the html in the attributes, I haven't found any topics that talk about this do you have an idea please?
In the examples I made on purpose not to put src to see the alternative texts.
Vue.component('first-image', {
inheritAttrs: false,
template: '<div class="container-image"><img v-bind="$attrs"></div>'
});
Vue.component('second-image', {
template: '<img>',
});
new Vue({
el: '#app',
data() {
return {
alternativeText: '1 000€',
};
},
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<!-- Without VueJS -->
<img alt="1 000€">
<br>
<br>
<!-- With VueJS -->
<div id="app">
<first-image :alt="alternativeText"></first-image>
<second-image alt="1 000€"></second-image>
</div>
You can try like following snippet:
Vue.component('first-image', {
inheritAttrs: false,
template: '<div class="container-image"><img v-bind="$attrs"></div>'
});
Vue.component('second-image', {
template: '<img>',
});
new Vue({
el: '#app',
data() {
return {
alternativeText: '1 000€',
};
},
methods: {
decodeHtml(html) {
const txt = document.createElement("textarea");
txt.innerHTML = html;
return txt.value;
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<!-- Without VueJS -->
<img alt="1 000€">
<br>
<br>
<!-- With VueJS -->
<div id="app">
<first-image :alt="decodeHtml(alternativeText)"></first-image>
<second-image alt="1 000€"></second-image>
</div>
I'm trying to add a button that would enable me to copy a snippet of code that is in view to the clipboard for a code catalog application in vue.js.
When I use the vue clipboard library and attempt this in the example component:
<div class="full-screen-code-snippet">
{{ example.codeSnippet }}
</div>
<div class="full-screen-copy-button">
<button v-clipboard:copy="example.codeSnippet"></button>
</div>
the snippet displays properly but the button does not. What's going on? How should I go about making this button?
You should be using it like : v-clipboard="variableName" or with :copy the same .
you can read more about it here or this one
<template id="t">
<div class="container">
<input type="text" v-model="message">
<button type="button"
v-clipboard:copy="message"
v-clipboard:success="onCopy"
v-clipboard:error="onError">Copy!</button>
</div>
</template>
<script>
new Vue({
el: '#app',
template: '#t',
data: function () {
return {
message: 'Copy These Text'
}
},
methods: {
onCopy: function (e) {
alert('You just copied: ' + e.text)
},
onError: function (e) {
alert('Failed to copy texts')
}
}
})
</script>
Hello how i can get the element by className or something else. So i need to get element by className actually but i can't figure out how to do that in this case:
here is my fiddle: https://jsfiddle.net/cihanzengin/aq9Laaew/294154/
Simply i wanna do that: When click to menu in method i try to get element which have classname nav. I tried to make with ref but i can't
here is my code :
<div id="app">
<some-component #get-element="getElement"></some-component>
</div>
<script>
var someComponent = Vue.component("some-component", {
template: `
<div class="columns mobile-navigation">
<div class="column drawer">
<a class="is" #click="$emit('get-element')">MENU</a>
</div>
<div ref="nav" class="column mobile-nav-wrapper">
<p> Some Text </p>
</div>
</div>
`
});
var app = new Vue({
el: '#app',
data: {
},
components: {
"mobile-nav": mobileNav
},
methods: {
getElement() {
console.log(this.$refs.nav);
}
}
});
</script>
You can try something like this.
var classToCheck = 'myclass';
if( this.$refs.nav.classList.includes(classToCheck) ){
// includes above class
}
OR
myclickevent(event){
event.target.classList // this will get you classList of of clicked element then you can compare
}
This contains all the classes for your element
this.$refs.nav.classList
i found the solution:
here is need to add **<some-component>** to ref attribute for accessing to ref inside jsx.
Then will possible to access to nav ref with: this.$refs.someRef.$refs.nav
<div id="app">
<some-component #get-element="getElement" ref="someRef"></some-component>
</div>
<script>
var someComponent = Vue.component("some-component", {
template: `
<div class="columns mobile-navigation">
<div class="column drawer">
<a class="is" #click="$emit('get-element')">MENU</a>
</div>
<div ref="nav" class="column mobile-nav-wrapper">
<p> Some Text </p>
</div>
</div>
`
});
var app = new Vue({
el: '#app',
data: {
},
components: {
"mobile-nav": mobileNav
},
methods: {
getElement() {
console.log(this.$refs.someRef.$refs.nav);
}
}
});
</script>
Here is my code, this is just a example code, if the below works then this will help me to build something else that I am working on.
<template>
<div id="wrapper">
<div id="divOne">
<!-- Add or remove component here dynamically -->
</div>
<div id="divTwo">
<!-- Add or remove component here dynamically -->
</div>
<!-- There will be more divs like #divOne #divTwo above -->
<div>
<input type="radio" id="one" value="divOne" v-model="pickedDiv">
<label for="one">One</label>
</div>
<div>
<input type="radio" id="two" value="divTwo" v-model="pickedDiv">
<label for="two">Two</label>
</div>
<button #click="addComponent">Add Component</button>
</div>
</template>
<script>
import SomeComponent from './SomeComponent'
export default {
data() {
return {
pickedDiv: '',
pickedDivPreviously: ''
propItems: ['item1', 'item2']
}
}
methods: {
addComponent () {
//-- This is not working code but I need something like this --//
this.pickedDivPreviously = this.pickedDiv // event not sure how to get previously selected div
const divThatIsPicked = document.getElementById(this.pickedDiv)
const divThatWasPickedPreviously = document.getElementById(this.pickedDivPreviously)
// code here to remove/empty/destroy old component from 'divThatWasPickedPreviously'
divThatWasPickedPreviously.innerHTML = ""
// code here to add new component in 'divThatIsPicked'
divThatIsPicked.appendChild('<some-component :someProp="propItems" #someEvent="someFn">')
}
}
}
</script>
I don't want to distract you from answering actual question but If you are curious about what I am working then check this :) Here I am trying to add new child DIV at the end of the row when any row item is clicked.
I will be more than happy if this is converted to vue than the actual question asked above, as said please don't get distracted from actual question if you find it hard :)
I got help from JamesThomson in forum.vuejs.org, though the solution did not fix my issue but I got to understand the limitation or possibilities of using Vue.js.
JamesThomson says:
Yeah, your example code definitely won’t work. When working with Vue
you need to think in a data oriented way, not DOM oriented (like
jQuery)
Taken from your SO post:
Here I am trying to add new child DIV at the end of the row when any
row item is clicked.
I assume this is your end goal for this topic. A simple example of
this can be achieved like so:
https://codepen.io/getreworked/pen/XZOgbm?editors=1010
let Welcome = {
template: `
<p #click="toggleMsg()">Welcome {{ msg }}!</p>
`,
data () {
return {
msg: 'home'
}
},
methods: {
toggleMsg () {
return this.msg = this.msg === 'home' ? 'back' : 'home';
}
}
}
const App = new Vue({
el: '#app',
data: {
children: [
Welcome
]
},
methods: {
add () {
this.children.push(Welcome);
},
}
});
<link rel="stylesheet" href="//cdn.rawgit.com/milligram/milligram/master/dist/milligram.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<div id="app">
<template v-for="(child, index) in children">
<component :is="child" :key="child.name"></component>
</template>
<button #click="add()">Add Another</button>
</div>
or you can use a render function for more flexibility
https://jsfiddle.net/jamesbrndwgn/ku7m1dp0/9/
const Reusable = {
template: '<div>{{ name }} {{ bar }}</div>',
props: {
name: {
type: String
}
},
data () {
return {
bar: 'Bar'
}
}
}
const App = new Vue({
el: '#app',
data: {
items: []
},
methods: {
addComponent () {
const renderComponent = {
render (h) {
return h(Reusable, {
class: ['foo'],
props: {
name: 'Foo'
}
})
}
}
this.items.push(renderComponent)
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>
<link rel="stylesheet" href="//cdn.rawgit.com/milligram/milligram/master/dist/milligram.min.css">
<div id="app">
<component v-for="item in items" ref="itemRefs" :is="item" :key="item.name"></component>
<button #click="addComponent">Add Component</button>
</div>
I found one of the other ways that does kinda same as above but work only with old vue.js-1 not with vue.js-2:
var createNewBox = function() {
var MyPartial = Vue.extend({});
window.partial = new MyPartial({
template: '#partial',
data: function() {
return {
txt: 'This is partial'
}
},
methods: {
print: function() {
console.log('this.txt : ' + this.txt)
console.log('main.txt : ' + main.txt)
},
},
})
window.partial.$mount().$appendTo('body')
}
window.main = new Vue({
el: '#main',
data: function() {
return {
txt: 'This is main'
}
},
methods: {
show: function() {
createNewBox()
}
},
})
<script src="https://cdn.bootcss.com/vue/1.0.17/vue.min.js"></script>
<div #click="show" style="width:200px;height:200px;background:#000" id="main">
<template id="partial">
<div style="width:100px;height:100px;background:#ff0" #click.stop="print"></div>
</template>
</div>
this converted to Vue.
https://codepen.io/jacobgoh101/pen/Kojpve
<div id="app">
<div class="parent">
<div class="child" #click="handleChildClick" data-new-child-id="1">1234</div>

<div class="new-child" v-if="[9].indexOf(showNewChild) > -1">boom</div>
</div>
</div>
Javascript
new Vue({
el: '#app',
data: {
showNewChild:null
},
methods: {
handleChildClick(e) {
let id = e.target.dataset.newChildId;
id = Number(id);
this.showNewChild = id;
}
}
})
I have a very basic vue.js app:
var app = new Vue({
el: '#app',
delimiters: ['${', '}'],
data: {
messages: [
'Hello from Vue!',
'Other line...'
]
}
})
The following html works fine:
<div class="container" id="app">
<div class="row" style="">
<div class="col-md-8 offset-md-2">
<span v-for="msg in messages">${msg}</span>
</div>
</div>
</div>
However very similar html block does not:
<div class="container" id="app">
<div class="row" style="">
<div class="col-md-8 offset-md-2">
<textarea id="chat_area" readonly="" rows="20">
<span v-for="msg in messages">${msg}</span>
</textarea>
</div>
</div>
</div>
[Vue warn]: Property or method "msg" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.
I'm using Vue v2.3.3. What could be the problem?
As documentation says, interpolation in textareas won't work, so you need to use v-model.
If the only thing you want to do is to display html inside textarea, you could in theory use an ugly workaround by wrapping your array fields inside a function and set that function as textarea v-model:
var app = new Vue({
el: '#app',
delimiters: ['${', '}'],
data: {
messages: [
'Hello from Vue!',
'Other line...'
]
},
computed:{
multiLineMessages: function(){
var result = "";
for(var message of this.messages){
result += '<span>' + message + '</span>'
}
return result;
}
}
});
template part:
<div class="container" id="app">
<div class="row" style="">
<div class="col-md-8 offset-md-2">
<textarea v-model="multiLineMessages" placeholder="add multiple lines">
</textarea>
</div>
</div>
</div>
It's more like a proof that it's doable but I highly don't recommend using it anywhere, as html shouldn't be generated this way (especially larger chunks of it).
