I am using the Trix editor and trying to render some stored content inside the box, but nothing is showing.
My Trix editor component wrapper:
<template>
<div>
<input type="hidden" :id="id" :name="name" :value="storedContent ? storedContent : 'blank'" />
<trix-editor :input="id"></trix-editor>
</div>
</template>
<script>
import Trix from "trix";
export default {
props: ["id", "name", "storedContent"]
};
</script>
The editor on the page doesn't render anything, regardless if I provide the stored-content prop.
It just shows an empty editor.
However, on inspection the hidden input does show the stored-content (or 'blank') on the page.
<input id="job-full-desc" type="hidden" name="full_description" value="blank">
The 'blank' value gets overwritten as soon as I write anything in the box.
Any thoughts?
I tried the following , when the component created I manually add the value to trix innerHTML
hoppefully can assist you thaks
<template>
<div>
<input :id="id" type="hidden" :name="name" :value="value">
<trix-editor ref="trix" :input="id" :placeholder="placeholder" style="min-height:300px"></trix-editor>
</div>
</template>
<script>
import Trix from 'trix';
import 'trix/dist/trix.css';
export default {
props: ['name', 'value', 'placeholder', 'shouldClear' , 'id'],
mounted () {
this.$refs.trix.innerHTML = this.value;
console.log(this.$refs.trix.innerHTML);
}
};
</script>

I am using vue components in a Laravel project.
I have taken sample code from https://vuejs.org/guide/components/events.html#usage-with-v-model
I have a child component with an input box:
<script>
export default {
props: ['modelValue'],
emits: ['update:modelValue']
}
</script>
<template>
<input
:value="modelValue"
#input="$emit('update:modelValue', $event.target.value)"
/>
</template>
This component is being used in a parent component.
<phone-input v-model="phone"/> {{phone}}
The parent component displays the input box with the initial value of the phone variable. However, the changed value is not reflected in the parent's phone variable ( {{phone}} does not update). Am I missing something? I have cleared the cache, but it did not help.
I tried another variation of the code (from vue.js documentation code) as given here. However, this also does not work.
Parent
<MyComponent v-model:title="bookTitle" />. {{bookTitle}}
<!-- Child Component MyComponent.vue -->
<script>
export default {
props: ['title'],
emits: ['update:title']
}
</script>
<template>
<input
type="text"
:value="title"
#input="$emit('update:title', $event.target.value)"
/>
</template>
Thanks for your help.
Take a look at following snippet, looks ok:
const app = Vue.createApp({
data() {
return {
phone: "0123456"
}
},
})
app.component('phoneInput', {
template: `
<input
:value="modelValue"
#input="$emit('update:modelValue', $event.target.value)"
/>
`,
props: ['modelValue'],
emits: ['update:modelValue'],
})
app.mount("#demo")
<script src="https://unpkg.com/vue#3/dist/vue.global.prod.js"></script>
<div id="demo">
<phone-input v-model="phone"></phone-input>
{{ phone }}
</div>
<script>
export default {
props: ['modelValue'],
}
</script>
<template>
<input
:value="modelValue"
#input="$emit('input', $event.target.value)"
/>
</template>
You need specially emit input to make it work
I want to embed a checkbox inside a Vue3 Component and have the v-model binding passed down to the checkbox.
Inside the Component:
<!-- Tile.vue -->
<template>
<div>
<input type=checkbox v-model="$attrs">
</div>
</template>
<script>
export default {inheritAttrs: false}
</script>
Then in an outside file:
<template>
<Tile value="carrot" v-model="foods" />
<Tile value="tomatoes" v-model="foods" />
</template>
<script setup>
var foods = ref([]);
</script>
How do I achieve this?
The documentation says that v-model is just a shorthand for :modelValue and #update:modelValue but this is not universal as Vue obviously behaves differently for form elements such as smartly listening to onchange instead of oninput and modifying the property checked instead of value depending on the node.
If I use v-model on the outer component, how do I forward it to the checkbox and get the same smart behavior that Vue has?
I have found tons of controversial information. Some recommend using #input event (Vue 3 custom checkbox component with v-model and array of items). Some recommend emitting modelValue:update instead of update:modelValue (https://github.com/vuejs/core/issues/2667#issuecomment-732886315). Etc.. Following worked for me after hour of trial and error on latest Vuejs3
Child
<template>
<div class="form-check noselect">
<input class="form-check-input" type="checkbox" :id="id" :checked="modelValue" #change="$emit('update:modelValue', $event.target.checked)" />
<label class="form-check-label" :for="id"><slot /></label>
</div>
</template>
<script>
import { v4 as uuidv4 } from "uuid";
export default {
inheritAttrs: false,
emits: ["update:modelValue"],
props: {
modelValue: {
type: Boolean,
required: true,
},
},
setup() {
return {
id: uuidv4(),
};
},
};
</script>
Parent:
<Checkbox v-model="someVariable">Is true?</Checkbox>
you can verify that it works but doing this in parent:
var someVariable= ref(false);
watch(someVariable, () => {
console.log(someVariable.value);
});
p.s. The other solution above does not work for me. Author recommends using value property. But in example he passes v-model attribute. So I don't know exactly how it's supposed to work.
You can achieve the behavior by using emits to keep data in sync and behave as default v-model behavior. Checkbox component:
<template>
<div>
<input
type="checkbox"
:checked="value"
#change="$emit('input', $event.target.checked)"
/>
{{ text }}
</div>
</template>
<script>
export default {
name: "inputcheckbox",
props: ["value", "text"],
};
</script>
And in the parent component you can have as many checkboxes you want.
<template>
<div id="app">
<maincontent :showContent="showContent" />
<inputcheckbox text="one" v-model="checkedOne" />
<inputcheckbox text="two" v-model="checkedTwo" />
</div>
</template>
Here is a vue 2 example but is applicable to vue 3 as well. Hope this was helpful. Sandbox with this behavior:

In this example, I'm trying to fit the value from div id="message" into textarea using the Vue v-model construct, but this not work
<template>
<div>
<textarea v-model="text"></textarea>
</div>
<div>
<div id="message" v-model="text2">{{ comment.message }}</div>
<button #click="update(text2);">
Edit
</button>
</div>
</template>
<script>
export default {
data() {
return {
text: [],
text2: null
}
},
methods: {
/* not work */
update(text2) {
this.text = text2;
}
}
<script>
How do I make sure that when I click on the "edit" button, the value of v-model="text2" insert into v-model="text" ?
You cannot use v-model on a <div> because it isn't an input element.
It seems what you want to do is set text to the comment message when you click the edit button so that it can be edited by the textarea. All you have to do is pass comment.message as the argument:
<button #click="update(comment.message)">
A couple of other things:
You cannot have multiple root elements in your template (you have two root <div> elements). You can just wrap everything in a single <div>.
text has initial value [] which isn't compatible with a textarea's v-model; did you mean ''?
I'm going to display a search box on my Vue website, but it won't display.
My code is (this in body.vue):
<template>
<div class="searching">
<input type="text" v-model="search" placeholder="Search.." />
</div>
</template>
I put it in the data()
export default {
name: "body",
data() {
return {
search: '',
My App.vue looks like this:
<template>
<div id="app">
<header id="header"></header>
<router-view id="routeView"></router-view>
</div>
</template>
The data() return also contain other stuff. Why can I see my searching box?
my child component is like this
<editor v-model="edit_thread.body"></editor>
and then I access the component from inside like this
<template>
<div>
<input :value="this.value">
</div>
</template>
<script>
export default {
data() {
return {
value: this.edit_thread.body
}
}
}
</script>
not working, I miss something?
To use v-model on custom components, the component needs to:
have a prop (not a data property) named value:
<template>
<div>
<input :value="value">
</div>
</template>
<script>
export default {
props: ['value']
}
</script>
and emit an input event with new values:
<template>
<div>
<input #input="$emit('input', $event.target.value)">
</div>
</template>
