VeeValidate 3 setErrors error message for current input change - vue.js

I have validation on two inputs. And I want to set the error message on two inputs using the setErrors() method of vee-validate the same time when I change data in the input.
Problem: Don't show message error on current input change data
Expect Result: I want to see the message error on two inputs.
<template>
<div>
<ValidationObserver ref="adad" v-slot="{ passes }">
<ValidationProvider name="min" mode="lazy" rules="required" v-slot="{ errors }">
<input type="number" v-model.number="minValue" #change="handleErrors">
<span>{{ errors[0] }}</span>
</ValidationProvider>
<ValidationProvider name="max" mode="lazy" rules="required" v-slot="{ errors }">
<input type="number" v-model.number="maxValue" #change="handleErrors">
<span>{{ errors[0] }}</span>
</ValidationProvider>
<button #click="passes(handleErrors)">Validate</button>
</ValidationObserver>
</div>
</template>
<script>
import { extend } from "vee-validate";
extend("between", {
params: ["min", "max"],
validate(value, { min, max }) {
return value >= min && value <= max;
},
message: "This field value must be between {min} and {max}"
});
export default {
data: () => ({
minValue: 0,
value: 1,
maxValue: 10
}),
methods: {
handleErrors() {
console.log("====> handleErrors");
this.$refs.adad.setErrors({
min: "hello world",

Including text when an image/icon is shown

At the moment I am trying to include different text when an image and/or icon shows on the page. Here is the code for the vue file:
<template>
<div class="profile">
<div
:class="{
'flags--relevant': hasFlagType('medication'),
'flags--active': flag == 'medication'
}"
class="flags"
#click="setFlag('medication')"
>
<medication-icon
:class="[
hasFlagType('medication')
? 'medication-icon--focus'
: 'medication-icon--blur',
]"
/>
</div>
<div
:class="{
'flags--relevant': hasFlagType('condition'),
'flags--active': flag == 'condition'
}"
class="flags"
#click="setFlag('condition')"
>
<treatment-icon
:class="[
hasFlagType('condition')
? 'treatment-icon--focus'
: 'treatment-icon--blur',
]"
/>
</div>
<div
:class="{
'flags--relevant': hasFlagType('translator'),
'flags--active': flag == 'translator',
}"
class="flags"
#click="setFlag('translator')"
>
<foreign-dialect-icon
:class="[
hasFlagType('translator')
? 'foreign-dialect-icon--focus'
: 'foreign-dialect-icon--blur',
]"
/>
</div>
</div>
</template>
<script>
export default {
components: {
ForeignDialectIcon,
MedicationIcon,
TreatmentIcon,
},
props: {
userFlags: {
type: Array,
default() {
return {};
},
},
},
data() {
return {
flags: this.userFlags,
flag: null,
title: "Requires daily medication",
title2: "Specialist health condition",
title3: "Requires a translator",
};
},
methods: {
hasFlagType(flagType) {
return this.flags[flagType] !== undefined;
},
setFlag(flagType) {
if (this.hasFlagType(flagType)) {
this.flag = flagType;
}
},
resetFlag() {
this.flag = null;
},
},
};
</script>
I have tried outputting the titles in the data section for each icon and they still show even if the icon doesn't show. I need it to output the title when the image is shown and the many attempts I've tried haven't worked so was wondering how I am able to solve this?
Assuming the title should only appear when the corresponding icon is focused, you could use the same condition (hasFlagType(...)) with v-if to render the title:
<div>
<medication-icon .../>
<span v-if="hasFlagType('medication')">{{ title }}</span>
</div>
<div>
<treatment-icon .../>
<span v-if="hasFlagType('condition')">{{ title2 }}</span>
</div>
<div>
<foreign-dialect-icon .../>
<span v-if="hasFlagType('translator')">{{ title3 }}</span>
</div>

Removing specific object from array keeps removing last item

Here is what I have and I will explain it as much as I can:
I have a modal inside my HTML code as shown below:
<div id="favorites-modal-edit" class="modal">
<div class="modal-background"></div>
<div class="modal-card px-4">
<header class="modal-card-head">
<p class="modal-card-title">Favorites</p>
<button class="delete" aria-label="close"></button>
</header>
<section class="modal-card-body">
<div class="container">
<div id="favorites-modal-edit-wrapper" class="columns is-multiline buttons">
<favorites-edit-component v-for="(favorite, index) in favorites_list" :key="favorite.id" :favorite="favorite" />
</div>
</div>
</section>
<footer class="modal-card-foot">
<button class="button" #click="addItem">
Add Item
</button>
</footer>
</div>
</div>
The id="favorites-modal-edit" is the Vue.js app, then I have the <favorites-edit-component /> vue.js component.
Here is the JS code that I have:
I have my favorites_list generated which is an array of objects as shown below:
const favorites_list = [
{
id: 1,
name: 'Horse',
url: 'www.example.com',
},
{
id: 2,
name: 'Sheep',
url: 'www.example2.com',
},
{
id: 3,
name: 'Octopus',
url: 'www.example2.com',
},
{
id: 4,
name: 'Deer',
url: 'www.example2.com',
},
{
id: 5,
name: 'Hamster',
url: 'www.example2.com',
},
];
Then, I have my vue.js component, which is the favorites-edit-component that takes in the #click="removeItem(this.index) which is coming back as undefined on the index.
Vue.component('favorites-edit-component', {
template: `
<div class="column is-half">
<button class="button is-fullwidth is-danger is-outlined mb-0">
<span>{{ favorite.name }}</span>
<span class="icon is-small favorite-delete" #click="removeItem(this.index)">
<i class="fas fa-times"></i>
</span>
</button>
</div>
`,
props: {
favorite: Object
},
methods: {
removeItem: function(index) {
this.$parent.removeItem(index);
},
}
});
Then I have the vue.js app that is the parent as shown below:
new Vue({
el: '#favorites-modal-edit',
// Return the data in a function instead of a single object
data: function() {
return {
favorites_list
};
},
methods: {
addItem: function() {
console.log('Added item');
},
removeItem: function(index) {
console.log(index);
console.log(this.favorites_list);
this.favorites_list.splice(this.favorites_list.indexOf(index), 1);
},
},
});
The problem:
For some reason, each time I go to delete a item from the list, it's deleting the last item in the list and I don't know why it's doing it, check out what is happening:
This is the guide that I am following:
How to remove an item from an array in Vue.js
The item keeps coming back as undefined each time the remoteItem() function is triggered as shown below:
All help is appreciated!
There is an error in your favorites-edit-component template, actually in vue template, when you want to use prop, data, computed, mehods,..., dont't use this
=> there is an error here: #click="removeItem(this.index)"
=> in addition, where is index declared ? data ? prop ?
you're calling this.$parent.removeItem(index); then in removeItem you're doing this.favorites_list.splice(this.favorites_list.indexOf(index), 1); this means that you want to remove the value equal to index in you array no the value positioned at the index
=> this.favorites_list[index] != this.favorites_list[this.favorites_list.indexOf(index)]
In addition, I would suggest you to modify the favorites-edit-component component to use event so it can be more reusable:
favorites-edit-component:
<template>
<div class="column is-half">
<button class="button is-fullwidth is-danger is-outlined mb-0">
<span>{{ favorite.name }}</span>
<span class="icon is-small favorite-delete" #click="$emit('removeItem', favorite.id)">
<i class="fas fa-times"></i>
</span>
</button>
</div>
</template>
and in the parent component:
<template>
...
<div id="favorites-modal-edit-wrapper" class="columns is-multiline buttons">
<favorites-edit-component
v-for="favorite in favorites_list"
:key="favorite.id"
:favorite="favorite"
#removeItem="removeItem($event)"
/>
</div>
...
</template>
<script>
export default {
data: function () {
return {
favorites_list: [],
};
},
methods: {
...
removeItem(id) {
this.favorites_list = this.favorites_list.filter((favorite) => favorite.id !== id);
}
...
},
};
I would restructure your code a bit.
In your favorites-edit-component
change your removeItem method to be
removeItem() {
this.$emit('delete');
},
Then, where you are using your component (in the template of the parent)
Add an event catcher to catch the emitted "delete" event from the child.
<favorites-edit-component v-for="(favorite, index) in favorites_list" :key="favorite.id" :favorite="favorite" #delete="removeItem(index)"/>
The problem you have right now, is that you are trying to refer to "this.index" inside your child component, but the child component does not know what index it is being rendered as, unless you specifically pass it down to the child as a prop.
Also, if you pass the index down as a prop, you must refer to it as "index" and not "this.index" while in the template.

How to validate on input event with vee validate 3

I'm trying to make validation on input event, but the problem that when the event onInput fire in console.log(valid) - is not correct value because it validates the previos character, how to validate correcty on input event?
question.vue
<template>
<div>
<ValidationProvider v-slot="{ errors, passed }" name="question" rules="required|max:10000">
<e-form-group :error="errors[0]">
<template v-slot:label>
Question Text
</template>
<e-textarea
v-model="question"
name="question"
size="small"
#input="onInput($event, passed, name)"
></e-textarea>
</e-form-group>
</ValidationProvider>
<ValidationProvider v-slot="{ errors, passed }" name="button" rules="required|max:10000">
<e-form-group :error="errors[0]">
<template v-slot:label>
Button Text
</template>
<e-textarea v-model="button" name="button" size="small" #input="onInput($event, passed, name)"></e-textarea>
</e-form-group>
</ValidationProvider>
</div>
</template>
<script>
export default {
name: 'Question',
props: {
questionId: {
type: Number
}
},
data: () => ({
question: '',
button: '',
}),
methods: {
onInput(event, valid, name) {
console.log(event);
console.log(valid);
if (!valid) this.$emit({questionId: this.questionId, name: name})
},
},
};
</script>
The default is to validate on input already, so what you want to do is trigger the validation yourself, get the result, and then emit your event:
<ValidationProvider v-slot="{ errors, validate }" name="question" rules="required|max:10000">
<e-form-group :error="errors[0]">
<template v-slot:label>
Question Text
</template>
<e-textarea
v-model="question"
name="question"
size="small"
#input="onInput($event, validate, name)"
></e-textarea>
</e-form-group>
</ValidationProvider>
methods: {
onInput(event, validate, name) {
var self = this;
validate(event).then(function(result) {
if (result.valid) self.$emit({questionId: self.questionId, name: name})
});
},
},

v-if not working for form validation and displaying errors

I'm trying to validate a simple form that contains two fields:
A select box
A file field
If one of the fields aren't filled in, a div (containing an error label) should be rendered next to the corresponding input field.
The problem: My 'error divs' aren't rendered when pushing data to the errors object (if the form is invalid).
Please note my console.log statement, that tells me that my error object has a key 'file' and a key 'selectedSupplier'.
Side note: I'm following this example: https://v2.vuejs.org/v2/cookbook/form-validation.html
Differences are, that I'd like to show error labels next to the corresponding field and that I'm setting errors in my errors object, instead of a simple array. So what could I be doing wrong?
Thanks.
This is my Main.vue file:
<template>
<div>
<form #submit="upload">
<div class="mb-8">
<h1 class="mb-3 text-90 font-normal text-2xl">Import Order Csv</h1>
<div class="card">
<div class="flex border-b border-40">
<div class="w-1/5 px-8 py-6">
<label for="supplier_id" class="inline-block text-80 pt-2 leading-tight">Supplier</label>
</div>
<div class="py-6 px-8 w-1/2">
<select v-model="selectedSupplier" id="supplier_id" name="supplier_id" ref="supplier_id" class="w-full form-control form-input form-input-bordered">
<option v-for="supplier in suppliers" v-bind:value="supplier.id">{{ supplier.name }}</option>
</select>
<div v-if="errors.hasOwnProperty('selectedSupplier')" class="help-text error-text mt-2 text-danger">
Required.
</div>
</div>
</div>
<div class="flex border-b border-40">
<div class="w-1/5 px-8 py-6">

export default {
mounted() {
this.listSuppliers();
},
data() {
return {
errors: [],
file: '',
suppliers: [],
};
},
methods: {
checkForm() {
if (!this.selectedSupplier) {
this.errors.selectedSupplier = 'Supplier required';
}
if (!this.file) {
this.errors.file = 'File required';
}
},
listSuppliers() {
const self = this;
Nova.request()
.get('/tool/import-order-csv/suppliers')
.then(function (response) {
self.suppliers = response.data.data;
})
.catch(function (e) {
self.$toasted.show(e, {type: "error"});
});
},
handleFile: function (event) {
this.file = this.$refs.file.files[0];
},
upload: function (event) {
this.checkForm();
if (this.errors.hasOwnProperty('selectedSupplier') || this.errors.hasOwnProperty('file')) {
console.log(this.errors); // this actually shows both errors!
event.preventDefault();
}
const formData = new FormData();
formData.append('file', this.file);
formData.append('supplier_id', this.$refs.supplier_id.value);
const self = this;
Nova.request()
.post('/tool/import-order-csv/upload',
formData,
{
headers: {
'Content-Type': 'multipart/form-data'
}
}
).then(function (response) {
self.$toasted.show(response.data.message, {type: "success"});
})
.catch(function (e) {
self.$toasted.show(e.response.data.message, {type: "error"});
});
}
}
}
</script>
Apparently I had to use v-show instead of v-if, because v-if would be 'lazy' and will not render my error-div when the errors var gets filled.
It's working now, but not 100% sure if this is the best way, as I found another tutorial where v-if is used for form validation.(https://medium.com/#mscherrenberg/laravel-5-6-vue-js-simple-form-submission-using-components-92b6d5fd4434)
I was getting the same error, this is how I solved the problem,
<div v-if="errors.field1.length > 0 ? true : false"> // true or false
If you fix the code like this it will work
The reason might because the way you reassign object is not reactive, which not trigger v-if to re-calculate
this.errors.selectedSupplier = 'Supplier required';
this.errors.file = 'File required';
If you still want to use v-if , try change to this approach
this.errors = {...this.errors, selectedSupplier: 'Supplier required' }
this.errors = {...this.errors, file: 'File required' }
The way I handle my errors with VueJS is through lists and their length attribute.
I have an errors object in my data that looks like this:
errors: {
field1: [],
field2: [],
}
Then, when I submit the form, I will:
Empty all the lists for the errors (ie clearing the previous errors)
.push() new errors in the right lists (and .push() makes the Vue reactive)
Finally, in my form, my respective errors divs are displayed based on the length of the list:
<div class="error" v-if="errors.field1.length > 0">
use a v-for to display all the errors from the list
</div>
Hope it helps

Extend Vue function in component to display ID

I have a Vue component and I am using internalValue to access the value attribute. How would I extend this to also get the ID?
ie internalValue = value, id
I have tried but I don't know how to add this inside the internalValue function. I've even tried to only get the ID by changing all instances of value to id but it still spits out the value.
I'd be happy to have them as one ie value, id or access them like data.value and data.id
Initialise Vue
new Vue({
el: '#topic',
data: {
selectedTopic: null
}
});
Use Component
<div class="form-group" id="topic">
<topic v-model="selectedTopic"></topic>
</div>
Register Component
Vue.component('topic', require('./components/Topicselect.vue'));
Component
<template>
<div>
<label v-for="topic in topics" class="radio-inline radio-thumbnail">
<input type="radio" v-model="internalValue" name="topics_radio" :id="topic.id" :value="topic.name">
<span class="white-color lg-text font-regular text-center text-capitalize">{{ topic.name }}</span>
</label>
<ul class="hidden">
<li>{{ internalValue }}</li>
</ul>
</div>
</template>
<script>
export default {
props: ['value'],
data () {
return {
internalValue: this.value,
topics: []
}
},
mounted(){
axios.get('/vuetopics').then(response => this.topics = response.data);
},
watch: {
internalValue(v){
this.$emit('input', v);
console.log('Topicselect: the value is ' + this.internalValue);
}
}
}
</script>
Use the selected topic as your value. Basically, eliminate internalValue altogether, and just emit the topic associated with any given radio button when it's clicked. This will satisfy v-model, since it listens to input events (unless you customize it).
export default {
props: ['value'],
data () {
return {
topics: []
}
},
methods:{
selectValue(topic){
this.$emit('input', topic)
}
},
mounted(){
axios.get('/vuetopics').then(response => this.topics = response.data);
}
})
And your template
<template>
<div>
<label v-for="topic in topics" class="radio-inline radio-thumbnail">
<input type="radio" #click="selectValue(topic)" name="topics_radio" :id="topic.id" :value="topic.name" :checked="value && topic.id == value.id">
<span class="white-color lg-text font-regular text-center text-capitalize">{{ topic.name }}</span>
</label>
<ul class="hidden">
<li>{{ value }}</li>
</ul>
</div>
</template>
This will set selectedTopic in your Vue to a topic, which is something like
{
id: 2,
name: "some topic"
}
based on how you use it in your template.
Working example.
