How can I add success message to the user after clicking Send message button? For example "Message sent"
I have a perfectly working form I can insert data into database and through the form, writing data into text file. using axios after form validation. I am just struggling to show a success message after user clicks the button.
Thank you
You can do something after the Promise is returned, like :
await http.post("/message", {firstName: this.firstName, lastName: this.lastName, message: this.message, numbers: this.checkedNumbers}).then((response) => {
// Do something with the response
})
Then, you can pop a swal from SweetAlert documentation with the message you want to show.

I'm working with DOM and web API to POST some information about the company like name, worker's name.
But when I write something in the input DOM can't reach the value and return empty so I post an empty object.
That looks like :
adress: ""
companyName: ""
contactName: ""
contactTitle: ""
My form block:
<form>
<div class="form-group">
<label for="">Company Name</label>
<input
type="text"
class="form-control"
id="companyName"
placeholder="Company Name!"
/>
</div>
<div class="form-group">
<label for="">Contact Name</label>
<input
type="text"
class="form-control"
id="contactName"
placeholder="Contact Name!"
value=""
/>
</div>
<div class="form-group">
<label for="">Contact Title</label>
<input
type="text"
class="form-control"
id="contactTitle"
placeholder="Contact Title!"
/>
</div>
<div class="form-group">
<label for="">Country</label>
<input
type="text"
class="form-control"
id="inputCountry"
placeholder="Country!"
/>
</div>
</form>
And my JS code:
'use strict';
let inputCompanyName = document.getElementById('companyName');
let inputContactName = document.getElementById('contactName');
let inputContactTitle = document.getElementById('contactTitle');
let country = document.getElementById('inputCountry');
const btnSubmit = document.getElementById('submit');
let newCompany = {
companyName: inputCompanyName.value,
contactName: inputContactName.value,
contactTitle: inputContactTitle.value,
adress: country.value,
};
btnSubmit.addEventListener('click', e => {
e.preventDefault();
axios
.post('https://northwind.vercel.app/api/suppliers', newCompany)
.then(res => {
console.log('Response', res.data);
alert('Success!');
});
});
I tried innerHTML and innerText and form method but I cant solve this problem.
You're reading the values immediately upon loading the page, long before the user has had a chance to enter any values.
Instead, read the values in the click event:
btnSubmit.addEventListener('click', e => {
let newCompany = {
companyName: inputCompanyName.value,
contactName: inputContactName.value,
contactTitle: inputContactTitle.value,
adress: country.value,
};
// the rest of the click handler logic...
});
Hi and sorry for the Newbie-Question
I am trying to push a HTML-Input into an existing array on Button-click, but i cannot find my mistake.
Can anyone spot the mistake? The console.log(user) stays undefined and I don't know why the let newUser() I create does not get pushed into the array.
<template>
<div>
<form #submit.prevent="customSubmit">
<label>Name</label>
<input type="text" required name="name" id="name">
<label>E-mail:</label>
<input type="email" required name="email" id="email">
<label>Mobile Number</label>
<input type="number" required name="number" id="number">
</form>
<button type="submit" class=buttonSignup #click="customSubmit">Submit</button>
</div>
</template>
<script>
export default {
data() {
return{
user:[{
name: '',
email:'',
number:''
}]
};
},
methods: {
customSubmit(){
let newUser = {
name: document.getElementById('name').value,
email: document.getElementById('email').value,
number: document.getElementById('number').value
}
this.user.push(newUser)
console.log(this.user.value)
},
}
}
</script>
With Vue, you use v-model instead of directly accessing the DOM. For example, you can re-write your code by:
Change name=name to v-model=user.name
Use user and users. user collects one user's data and users collects all user input into an array. This is reflected in the modified customSubmit.
Reset user after each input.
There are more elegant ways to do this but this is the clearest and close enough to your original code.
<template>
<div>
<form #submit.prevent="customSubmit">
<label>Name</label>
<input type="text" required v-model="user.name" id="name">
<label>E-mail:</label>
<input type="email" required v-model="user.email" id="email">
<label>Mobile Number</label>
<input type="number" required v-model="user.number" id="number">
</form>
<button type="submit" class=buttonSignup #click="customSubmit">Submit</button>
<br/>
You typed:<br/>
name: {{user.name}}<br/>
email: {{user.email}}<br/>
number: {{user.number}}
</div>
</template>
<script>
export default {
data() {
return {
users: [],
user: {
name: '',
email: '',
number: ''
}
};
},
methods: {
customSubmit() {
// do some checking here
this.users.push(this.user)
this.user = {name:'', email:'', number:''};
console.log(this.users)
},
}
}
</script>
First of all I would like to apologize if the answer to my question is obvious, however since I'm still pretty new to Vue.js, I'm getting really stuck here and I need help.
I got an authentication system and if the user wants to register without putting in an username, I would like to show an bootstrap alert. The code looks like this right now:
<template>
<div class="container">
<div class="row">
<div class="col-md-6 mt-5 mx-auto">
<form v-on:submit.prevent="register">
<h1 class="h3 mb-3 font-weight-normal">Register</h1>
<div class="form-group">
<label for="username">Username</label>
<input
type="text"
v-model="username"
class="form-control"
name="username"
placeholder="Please choose your username"
>
</div>
<div class="form-group">
<label for="email">Email Address</label>
<input
type="email"
v-model="email"
class="form-control"
name="email"
placeholder="Please enter your email address"
>
</div>
<div class="form-group">
<label for="password">Password</label>
<input
type="password"
v-model="password"
class="form-control"
name="password"
placeholder="Please choose your password"
>
</div>
<button class="btn btn-lg btn-primary btn-block" type="submit">Register</button>
</form>
<div>
<b-alert variant="success" show>Example alert</b-alert>
</div>
<div>
<b-alert variant="danger" :show="showAlert">Example Alert!</b-alert>
</div>
</div>
</div>
</div>
</template>
<script>
import axios from "axios";
import router from "../router";
export default {
data() {
return {
username: "",
email: "",
password: "",
showAlert: false };
},
methods: {
register() {
axios
.post("/user/register", {
username: this.username,
email: this.email,
password: this.password
})
.then(res => {
if (!res.data.username) {
// show an alert, I would like to do something similar to "showAlert = true;"
} else {
// redirect to login
}
})
.catch(err => {
console.log(err);
});
}
}
};
</script>
<style scoped>
#import "../assets/css/reglog.css";
#import "../assets/css/modal.css";
</style>
However I'm not sure how to access the showAlert variable neither how to change its value in the if-statement. The only thing that I know here is that if I change the showAlert manually in the code (line 9 counting from the script tag) from false to true, the page does react and shows the alert when wanted.
I'm sorry if you need more information or if something is unclear, I'm a bit tired and stuck with this for some hours, not gonna lie.
You can access showAlert variable following: this.showAlert = true
.then(res => {
if (!res.data.username) {
this.showAlert = true; // update showAlert
} else {
// redirect to login
}
})
i I want to insert my my in database.axios is perfect and enter data in db but I want a message 'data is entered' for the user ->
how it is important to insert the message.
thanks

<script>
import axios from 'axios'
export default {
name: 'hello',
data() {
return {
msg: 'Welcome to Your Vue.js App',
User: { first_name: '', last_name: '', email: '' }
}
},
methods: {
addToAPI() {
let newUser = {
first_name: this.User.first_name,
last_name: this.User.last_name,
email: this.User.email
}
console.log(newUser)
axios.post('http://localhost:3000/(localaccess)',newUser)
.then(response => {
console.log('success:', response)
})
.catch(error => {
console.log('error:', error)
})
}
}
}
</script>
Add a data object where you will store the message, like:
<script>
import axios from 'axios'
export default {
name: 'hello',
data() {
return {
msg: 'Welcome to Your Vue.js App',
User: { first_name: '', last_name: '', email: '' },
message: ''
}
},
methods: {
addToAPI() {
let self = this;
let newUser = {
first_name: this.User.first_name,
last_name: this.User.last_name,
email: this.User.email
}
axios.post('http://localhost:3000/(localaccess)',newUser)
.then(response => {
self.message = 'Data is entered'
})
.catch(error => {
self.message = 'Error'
})
}
}
}
</script>
And now add it to some place ih your template - {{message}}.
This is my first bigger form with validations and etc.
I've created a Registration form and I'm using ng-messages for validation. The problem is that I need to validate the username, does it already exist in the JSON server that we are using or it's available. Of course, if it's taken the warning pops out in the HTML where the username input is, if it's available the submit button is no more disabled (because the form will be $valid) and the user can register. I want to use angular-sanitize because I found this (I don't know if they are related):
ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
var value = modelValue || viewValue;
// Lookup user by username
return $http.get('/api/users/' + value).
then(function resolved() {
//username exists, this means validation fails
return $q.reject('exists');
}, function rejected() {
//username does not exist, therefore this validation passes
return true;
});
};
Here is the code I use now (reg form, controller and service):
// Controller:
export default class registerPageController {
constructor(userService, authenticationService, $location) {
this.register = "Register";
this.userService = userService;
this.$location = $location;
this.authenticationService = authenticationService;
this.hasLoggedIn = false;
}
onSubmit(user) {
let self = this;
let {
name,
age,
email,
username,
password
} = user;
self.userService.register(name, age, email, username, password).then((res) => {
self.userService.login(username, password).then(function (response) {
let data = response.data;
if (data.length) {
let user = data[0];
self.hasLoggedIn = true;
self.authenticationService.setCredentials(username, password);
self.$location.path('/');
}
});
})
.catch(err => {
// WHAT TO PUT HERE AFTER THE USERNAME EXIST VALIDATION ?
})
}
}
// Service:
export class UserService {
constructor($http) {
this.$http = $http;
}
login(username, password) {
return this.$http({
method: 'GET',
url: 'http://localhost:3000/users',
params: {
username: username,
password: password
}
});
}
register(name, age, email, username, password) {
return this.$http({
method: 'POST',
url: 'http://localhost:3000/users',
data: {
name: name,
age: age,
email: email,
username: username,
password: password
}
});
}
// SHOULD I PUT HERE THE USERNAME EXIST VALIDATION LOGIC ?
}

Important is to know that I have being told explicitly to write it in ES6.
I have problem with the logic so look at my code and please fill it for me so I can use it and most important - learn it :S
Thank you so so much in advance!
I have implemented a directive for different kind of validations (sync Async), and it supports warning as well.
