As you can see in the picture, I have a text editor with Quill. this is admin panel in my project and when I write something in my text editor and want to display it, it is working fine. For example, if I want to write a description in bold it goes to the front end like this: Description and I can display it with this code:
<div v-html="product.attributes.description"></div>
But my problem is I want to show this value inside of y text editor. So I want to show bold written 'Description' in my text editor instead of undefined but I couldnt figured out how to do it with Quill text editor. Here is my text-editor component:
<template>
<div class="form-control" v-bind:class="inputClasses" ref="editor"></div>
</template>
<script>
import Quill from 'quill';
import 'quill/dist/quill.core.css';
import 'quill/dist/quill.bubble.css';
import 'quill/dist/quill.snow.css';
export default {
props: {
modelValue: { type: String, default: '' },
defaultValue: "",
},
data() {
return {
editor: null,
};
},
mounted() {
var _this = this;
this.editor = new Quill(this.$refs.editor, {
modules: {
toolbar: [
[{ header: [1, 2, 3, 4, false]} ],
["bold", "italic", "underline", "link", "image"],
],
},
theme: "snow",
formats: ["bold", "underline", "header", "italic", "link"],
placeholder: this.placeholder
});
this.editor.root.innerHTML = this.defaultValue;
this.editor.on("text-change", function () {
return _this.update();
});
},
methods: {
update: function update() {
this.$emit(
"update:modelValue",
this.editor.getText() ? this.editor.root.innerHTML : ""
);
},
},
}
</script>
If I understood your question properly, you want to set the value of the editor?
If so, I had the same problem and was able to resolve using this answer: How to use v-model in quill editor
<quill-editor v-model:content="modelname" contentType="html" />
Then you can set and retrieve the editor content using the 'modelname' property. Hope it helps!
How I got rid of the undefined value when contentType='html'.
<QuillEditor theme="snow" ref="quill" v-model:content="modelName" contentType="html" placeholder="Type job description here..." style="height: 300px"/>
mounted() {
this.$refs.quill.setContents('')
}

My application provides many selectable standard paragraphs which users can insert at any point. In a previous version insertion was simple: CKEDITOR.instances[editorId].insertHTML(text).
I'm trying to use v5 api with model.insertContent(text) but get error:
"vue.runtime.esm.js:3020 TypeError: t2.is is not a function
at bl.rp (converters.js:771:21)

Here's the composition file. I have tried accessing the insertContent method from this.editor and from the apiReference returned from the #ready event;
<template>
<div>
<button #click="testInsert('abracadabra')">Insert literal content</button>
<ckeditor tag-name="textarea" :editor="editor" v-model="doc.HTML" #ready="editorReady" :config="editorConfig"></ckeditor>
</div>
</template>
<script>
import ClassicEditor from '#ckeditor/ckeditor5-build-classic';
export default {
name: 'testEditorInsert',
mounted() {
},
data() {
return {
doc: {ID: 0, HTML: "This is a sample text. Insert here? This is the remainder of the sample text"},
editor: ClassicEditor,
editorData: 'loading',
editorConfig: {
toolbar: [ 'bold', 'italic', 'link', 'bulletedList', 'numberedList', 'blockQuote' ],
},
editorApi:null ,
}
},
methods: {
testInsert: function(text) {
console.log(this.editorApi, text);
//this.editor.model.insertContent(text);
this.editorApi.model.insertContent(text);
},
editorReady: function(editor) {
this.editorApi = editor;
}
},

I need a dropdown that supports tagging and can be styled easily, so I decided to implement vue-multiselect. It works but the problem is that I have a predefined tag in my dropdown when the page loads and I don't what that, how can I remove it? Here is how it looks now:
and here is how I want it to look:
Here is my html code:
<div>
<multiselect v-model="value" tag-placeholder="Add this as new tag" placeholder="Assesors" label="name" track-by="code" :options="options" :multiple="true" :taggable="true" #tag="addTag"></multiselect>
</div>
and here is my js:
data () {
return {
showAddUserDialog: false,
value: [
{ name: 'Assesors', code: 'as' }
],
options: [
{ name: 'Assesors', code: 'as' },
{ name: 'Finance', code: 'fi' },
{ name: 'Sales', code: 'sa' }
]
}
},
methods: {
addTag (newTag) {
const tag = {
name: newTag,
code: newTag.substring(0, 2) + Math.floor((Math.random() * 10000000))
}
this.options.push(tag)
this.value.push(tag)
}
}
Well, by the <multiselect> configuration you used and the expected behavior your showed...
You have this https://imgur.com/a/D9nEKfD to become this https://imgur.com/a/baTYXht
I looks like you want to load your page only showing the placeholder, but if you'd like to only show your placeholder, you shouldn't have a value in the value variable, as you have:
data () {
return {
showAddUserDialog: false,
value: [
{ name: 'Assesors', code: 'as' } // <- remove this
],
options: [
{ name: 'Assesors', code: 'as' },
{ name: 'Finance', code: 'fi' },
{ name: 'Sales', code: 'sa' }
]
}
}
Because the behavior of the component is show your current tags, right?
So if this tag is the placeholder, you can add it to the value when the user submits the form without choosing any other tag.
But if you want to have it there as the value and trickery the component to only show it as a placeholder, I suggest you to deep dive in the docs about custom templating...
Here talks about it https://vue-multiselect.js.org/#sub-custom-option-template
And here talks about the tags slots
https://vue-multiselect.js.org/#sub-slots
Here is an example:
I've just made a Link component in Vue, which is new for me. Now I need to make a Link list component, which is basically an UL of LI elements of this Link component. I looked for a solution, but most most of the examples do work with a local array/object and I can't seem to figure it out.
So my question here is: What would a Link list component look like, making use of the existent Link component?
Here's the Link component:
<template>
<nuxt-link
:to="localePath(url)"
:class="$style.link"
>
<Icon
v-if="icon"
class="icon icon--size:2.5x"
:name="icon"
/>
<span
class="text"
>
{{ text }}
</span>
</nuxt-link>
</template>
<script src="./index.js"></script>
<style type="text/css" src="./index.module.scss" module lang="scss"></style>
import { Icon } from "#/components";
export default {
props: {
text: {
type: String,
required: true,
default: "",
},
url: {
type: String,
required: true,
default: "",
},
icon: {
type: String,
required: true,
default: "",
},
expert: {
type: Boolean,
required: false,
default: false,
},
},
components: {
Icon,
},
};
Should the Link list component receive an array as well like this?
export default {
props: {
list: {
type: Array,
required: true,
default: "",
},
},
Link,
},
};
Assuming you have an array of link objects that provide the props text, url, icon and optionally expert (because I can't see where you're using that), if your goal is to pass this array as a prop to your Link List component, then it would look something like this
<template>
<ul>
<!-- note the ":key" binding. This should uniquely identify each entry in the list -->
<li v-for="({ text, url, icon }) in list" :key="url">
<Link
:text="text"
:url="url"
:icon="icon"
/>
</li>
</ul>
</template>
<script>
import { Link } from '#/components' // or whatever makes sense
export default {
name: 'LinkList',
components: { Link },
props: {
list: Array
}
}
</script>
Using this would look something like
<template>
<LinkList :list="list" />
</template>
<script>
import { LinkList } from '#/components'
export default {
components: { LinkList },
data: () => ({
list: [{
text: 'Link #1',
url: 'https://example.com',
icon: 'whatever'
}, {
// and so on
}]
})
}
</script>
I read Reactivity in Depth but can't solve the issue.
I'm creating a small single page app that contains images and text.
When the user clicks a button I want the language to change.
Currently I am storing the content in two files that export an object.
export default {
projects: [
{
title: 'Project Title',
year: 2016,
...
},
]
}
and importing that
import contentEn from './assets/content.en.js'
import contentDe from './assets/content.de.js'
new Vue({
el: '#app',
components: { App },
data: {
mainContent: {
content: contentEn
}
},
methods: {
switchToGerman(){
this.mainContent.content = contentDe
}
},
template: '<App :mainData="mainContent"/>',
})
When I assign another object to mainContent.content the rendering is not triggered.
I understand that adding and deleting properties from object don't lead to change detection but I switch out a whole object. I tried assigning it with this.$set with no success.
I also tried this and googled a lot but can't get it work.
Or is my approach just wrong?
Thank you for helping,
best,
ccarstens
EDIT:
See below the code for the App component and the ProjectElement
// App.vue
<template>
<div id="app">
<button #click="switchGerman">Deutsch</button>
<ProjectElement v-for="(project, key) in fullData.content.projects" :key="key" :content="project"/>
</div>
</template>
<script>
import ProjectElement from './components/ProjectElement'
export default {
name: 'App',
props: [
'mainData'
],
data () {
return{
fullData: {}
}
},
methods: {
switchGerman(){
this.$root.switchToGerman()
}
},
created(){
this.fullData = this.$props.mainData
},
watch: {
mainData: {
handler: function(newData){
this.fullData = newData
},
deep: true
}
},
components: {
ProjectElement,
}
}
</script>
And the ProjectElement
//ProjectElement.vue
<template>
<article :class="classObject" v-observe-visibility="{
callback: visibilityChanged,
throttle,
intersection: {
threshold
}
}">
<header v-html="description"></header>
<div class="content">
<carousel :per-page="1" :pagination-enabled="false">
<slide v-for="(slide, index) in projectContent.media" :key="index">
<VisualElement :content="slide" ></VisualElement>
</slide>
</carousel>
</div>
</article>
</template>
<script>
import {Carousel, Slide} from 'vue-carousel'
import VisualElement from './VisualElement'
export default {
name: "ProjectElement",
components: {
Carousel,
Slide,
VisualElement
},
props: [
'content'
],
data () {
return {
projectContent: {},
isVisible: false,
throttle: 300,
threshold: 0.8
}
},
created(){
this.projectContent = this.content
},
methods: {
visibilityChanged(isVisible){
this.isVisible = isVisible
}
},
computed: {
description(){
return `
<p>${ this.projectContent.title } - ${this.projectContent.year}</p>
<p>${ this.projectContent.description }</p>
`
},
classObject(){
return {
visible: this.isVisible,
'project-element': true
}
}
}
}
</script>
Did you try doing deep copy:
switchToGerman () {
const copyContent = JSON.parse(JSON.stringify(this.mainContent))
copyContent.content = contentDe
this.mainContent = copyContent
}
I found the solution (thank you #EricGuan for pointing out that the mistake must lay somewhere else)
As you can see in the original post I created a watcher for the mainData property and expected that this would trigger the re render.
What was missing is, that I didn't watch the content property on the ProjectElement component, thus not triggering a re render there.
I added this to ProjectElement.vue and now it works like a charm:
watch: {
content(newContent){
this.projectContent = newContent
}
},
Thank you everybody for helping me! <3
I am fairly new to vue and can't figure out how to add data values within a template. I am trying to build a very basic form builder. If I click on a button it should add another array of data into a components variable. This is working. The I am doing a v-for to add input fields where some of the attributes are apart of the array for that component. I get it so it will add the input but no values are being passed into the input.
I have created a jsfiddle with where I am stuck at. https://jsfiddle.net/a9koj9gv/2/
<div id="app">
<button #click="add_text_input">New Text Input Field</button>
<my-component v-for="comp in components"></my-component>
<pre>{{ $data | json }}</pre>
</div>
new Vue({
el: "#app",
data: function() {
return {
components: [{
name: "first_name",
showname: "First Name",
type: "text",
required: "false",
fee: "0"
}]
}
},
components: {
'my-component': {
template: '<div>{{ showname }}: <input v-bind:name="name" v-bind:type="type"></div>',
props: ['showname', 'type', 'name']
}
},
methods: {
add_text_input: function() {
var array = {
name: "last_name",
showname: "Last Name",
type: "text",
required: "false",
fee: "0"
};
this.components.push(array);
}
}
})
I appreciate any help as I know I am just missing something obvious.
Thanks
Use props to pass data into the component.
Currently you have <my-component v-for="comp in components"></my-component>, which doesn't bind any props to the component.
Instead, do:
<my-component :showname="comp.showname"
:type="comp.type"
:name="comp.name"
v-for="comp in components"
></my-component>
Here is a fork of your fiddle with the change.
while asemahle got it right, here is a boiled down version on how to expose data to the child component. SFC:
async created() {
await this.setTemplate();
},
methods: {
async setTemplate() {
// const templateString = await axios.get..
this.t = {
template: templateString,
props: ['foo'],
}
},
},
data() {
return {
foo: 'bar',
t: null
}
}
};
</script>
<template>
<component :is="t" :foo="foo"></component>
It pulls a template string that is compiled/transpiled into a js-render-function. In this case with Vite with esm to have a client-side compiler available:
resolve: {
alias: {
// https://github.com/vuejs/core/tree/main/packages/vue#with-a-bundler
vue: "vue/dist/vue.esm-bundler.js",
the index.js bundle size increases by few kb, in my case 30kb (which is minimal)
You could now add some what-if-fail and show-while-loading with defineasynccomponent
