Managing Mutations Vuejs - vue.js

Is this correct way of managing mutations?
My HTML
<div class="form-group">
<label>Merchant Id No:</label>
<input type="text" class="form-control border-input" v-model="merchantId">
</div>
<div class="form-group">
<label>Name:</label>
<input type="text" class="form-control border-input" v-model="merchantName">
</div>
My Computed Properties:
merchantId: {
get(){
return this.merchant.merchant_id
},
set(value){
this.$store.commit('merchantId', value);
}
},
merchantName: {
get(){
return this.merchant.name
},
set(value){
this.$store.commit('merchantName', value);
}
},
My Mutations:
merchantName(state, merchantName){
state.merchant.name = merchantName
},
merchantId(state, merchantId){
state.merchant.merchant_id = merchantId
},
Is there a way to mutate only in the merchant? Because I need to do it one by one.
merchant(state, merchant){
state.merchant = merchant
},
Here is my merchant Object.

You can add a button at the end of your input fields and add a click listener to commit a mutation withe the payload of merchant object.
Example
<div class="form-group">
<label>Merchant Id No:</label>
<input type="text" class="form-control border-input" v-model="merchant.merchantId">
</div>
<div class="form-group">
<label>Name:</label>
<input type="text" class="form-control border-input" v-model="merchant.merchantName">
</div>
<div class="form-group">
<label>Name:</label>
<input type="email" class="form-control border-input" v-model="merchant.merchantEmail">
</div>
// more input fields...
<button #click.prevent="save">Save merchant<button>
script
export default{
data(){
return{
merchant:{
merchantId:'',
merchantName:'',
merchantEmail:''
//more properties binded to the v-model
}
}
},
methods:{
click(){
this.$store.commit('merchant', this.merchant);
}
}
}
And your mutation
merchant(state, merchant){
state.merchant = merchant
},

Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property

I am trying make form validation dynamically, all props from the JSON file here I am passing the props parent to child component and that props using for input v-model.
When enter a letter inside the text input, I am getting the following error

import Vue from 'vue';
export const EventBus = new Vue();
If the orderPlace.vue component is not active when you do the emit. It cannot receive the element.
You can try to register your order number, in the localStorage. Or call orderPlace.vue as a child component and pass the order number to the props

VueJS - how can I add a hidden input to a form?

I created a Vue component that has several forms that can be submitted by the user. On submit, the form will send some data to my backend. The problem is that my backend needs to know which form was submitted, and this input doesn't depend on the user, so I added a hidden input so that when the user send the data, my backend can also know which type of form was submitted. I tried the following:
<template>
<div>
<div v-if="order=='total'">
<form #submit="formSubmit">
<input type="hidden" v-model="order_type" value="form1">
<input type="text" class="form-control" v-model="amount">
<br>
<input type="text" class="form-control" v-model="price">
<br>
<button class="btn btn-primary">BUY</button>
</form>
</div>
<div v-else-if="order=='partial'">
<input type="hidden" v-model="order_type" value="form2">
<input type="text" class="form-control" v-model="amount">
<br>
<input type="text" class="form-control" v-model="price">
<br>
<button class="btn btn-primary">BUY</button>
</form>
</div>
<br>
</div>
</template>
<script>
import axios from 'axios'
export default {
props:{
order:{
type:String,
default:'total'
},
},
mounted() {
console.log('Component mounted.')
},
data() {
return {
name: '',
description: '',
output: ''
};
},
methods: {
formSubmit(e) {
e.preventDefault();
let currentObj = this;
axios.post('MYURL', {
order_type: this.order_type,
price: this.price,
amount: this.amount
})
.then(function (response) {
currentObj.output = response.data;
})
.catch(function (error) {
currentObj.output = error;
});
}
}
}
</script>
The problem with this code is that order_type doesn't get sent with the form. I have read somewhere that Vue doesn't allow hidden values, so is there any other way to do this?
You can pass a param to the method:
#submit.prevent="formSubmit("form1")"
And in the method:
formSubmit(value) {
let currentObj = this;
axios
.post("MYURL", {
price: this.price,
amount: this.amount,
order_type: value
})
.then(function(response) {
currentObj.output = response.data;
})
.catch(function(error) {
currentObj.output = error;
});
},
Your template becomes:
<template>
<div>
<div v-if="order=='total'">
<form #submit.prevent="formSubmit("form1")">
<input type="text" class="form-control" v-model="amount">
<br>
<input type="text" class="form-control" v-model="price">
<br>
<button class="btn btn-primary" type="submit">BUY</button>
</form>
</div>
<div v-else-if="order=='partial'">
<form #submit.prevent="formSubmit("form2")">
<input type="text" class="form-control" v-model="amount">
<br>
<input type="text" class="form-control" v-model="price">
<br>
<button class="btn btn-primary" type="submit">BUY</button>
</form>
</div>
<br>
</div>
</template>
SOLUTION 2
To avoid duplication you could also set a computed property:
orderType(){
if (this.order === "total") {
return "form1"
} else if (this.order === "partial") {
return "form2"
} else {
return null
}
With that in place you can simplify the template by removing the conditional and not needing to pass anything to the method:
<template>
<div>
<form #submit.prevent="formSubmit()">
<input type="text" class="form-control" v-model="amount" />
<br />
<input type="text" class="form-control" v-model="price" />
<br />
<button class="btn btn-primary" type="submit">BUY</button>
</form>
</div>
</template>
And in the method the value of order_type is calculated in the computed property:
formSubmit() {
let currentObj = this;
axios
.post("MYURL", {
price: this.price,
amount: this.amount,
order_type: this.orderType
})
.then(function(response) {
currentObj.output = response.data;
})
.catch(function(error) {
currentObj.output = error;
});
},

Vue 2 Vuex - update values via form or add new item

I have following template:
<template>
<div class="is-half">
<form #submit.prevent="save">
<input type="hidden" name="bookID" :value="book.id">
<div class="field">
<label class="label">Title</label>
<div class="control">
<input class="input" type="text" placeholder="Title" :value="book.title">
</div>
</div>
<div class="control">
<div class="select">
<select>
<option
v-for="author in this.$store.state.authors"
:value="author.name"
:selected="author.name == book.author"
>{{ author.name }}</option>
</select>
</div>
</div>
<div class="field">
<label class="label">Description</label>
<div class="control">
<textarea class="textarea" placeholder="Description" :value="book.description"></textarea>
</div>
</div>
<div class="control">
<button class="button is-primary">Submit</button>
</div>
</form>
</div>
</template>
<script>
export default {
data() {
return {
book : {
id: null,
title: '',
isbn: '',
author: '',
description: '',
added: ''
}
}
},
methods: {
save(book) {
console.log(this.book);
}
},
created() {
if(this.$store.state.book != 'undefined'){
this.book = Object.assign({}, this.$store.state.book);
}
},
computed: {}
}
</script>
<style></style>
I am trying to update the value of selected item, but whenever I press save, the object has the same values which it gets on load.
How can I update values if the I load new object, or insert new object if id is null?
If i understand your question, the problem is that when you type something in the input, it doesn't update the model.
The problem is you're using :value to bind the values and this is a one-way binding. For 2 way binding replace all :value with v-model: v-model="book.title"

How can I get value when button clicked ? Vue.js 2

My component vue is like this :
<template>
<div class="modal" tabindex="-1" role="dialog">
...
<div class="form-group">
<input type="file" id="change-image" name="replace">
</div>
<div class="form-group">
<input type="text" class="form-control" id="alt-image">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> Set
</label>
</div>
...
<button type="button" class="btn btn-success" #click="editImageProduct">
{{trans('store.modal.edit.button.save')}}
</button>
...
</div>
</template>
<script>
export default{
...
methods: {
editImageProduct(event) {
// get the data
}
}
}
</script>
When I click the button, I want get value from input type file, input type text and intput type checkbox
I know use javascript or jquery
But I want to get it use vue.js 2
How can I do it?
With checkbox and text input, you can use v-model.
With file input you can get data when user upload image, use event onChange
Example code:
new Vue({
el: '#app',
data: {
image: '',
altImage: '',
set: false,
},
methods: {
onUpload(e) {
this.image = e.target.files || e.dataTransfer.files;
},
editImageProduct() {
console.log('File object', this.image);
console.log('Image name', this.image[0].name);
console.log('Alt Image', this.altImage);
console.log('Set', this.set);
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.min.js"></script>
<div id="app">
<div class="form-group">
<input type="file" #change="onUpload">
</div>
<div class="form-group">
<input type="text" class="form-control" v-model="altImage">
</div>
<div class="checkbox">
<label><input type="checkbox" v-model="set"> Set</label>
</div>
<button type="button" class="btn btn-success" #click="editImageProduct">Save</button>
</div>
use v-model in your form
<input type="file" id="change-image" name="replace" v-model="file">
<input type="text" class="form-control" id="alt-image" v-model="text">
<input type="checkbox" v-model="checkbox">
export default {
data: function(){
return {
file: null,
checkbox: null,
text: null,
}
},
methods: {
editImageProduct() {
console.log(this.file, this.checkox, this.text);
}
}
}
EDITED:
try to look into this example for file inputs, hope it'll help you http://codepen.io/Atinux/pen/qOvawK/
