How to get values from input boxes and save to database with button click angular

I'm still learning to programme on AngularJS.
I want to get values from the input box and then click on the button I want to save them in the database.
My database table is called "user". I have columns like id, username, password, name.
I have two checkbox.When I click on first checkbox(Edit) it displaying "div myVar",when i click on second checkbox(Add new user) it displaying "div myVar1".
I want to activate this button "Add" to add input box values to database MySQL. Please help me.
I have this html code:
<label><input type="checkbox" ng-model="myVar">Edit</label>
<label><input type="checkbox" ng-model="myVar1">Add new user</label>
<div ng-show="myVar">
<div class="form">
<form ng-submit="saveItem(userForm.$valid)" name="userForm">
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="database_address">User</label>
<input type="text" class="form-control" required ng-model="activeItem.username" placeholder="Потребителско Име..." />
</div>
<div class="form-group">
<label for="password">Password</label>
<input type="text" class="form-control" required id="password" ng-model="activeItem.password" />
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label for="username">Operator</label>
<input type="text" class="form-control" required id="username" ng-model="activeItem.name" />
</div>
</div>
</div>
<button class="btn btn-primary" ng-disabled="userForm.$invalid" type="submit">Save</button>
<!--<button class="btn btn-primary" ng-disabled="userForm.$invalid" type="submit">Добавяне на нов</button>-->
</form><form ng-submit="createUser(userForm.$valid)" name="userForm1">
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<label for="database_address">User</label>
<input type="text" class="form-control1" ng-model="usernamee" placeholder="Потребителско Име..." />
</div>
<div class="form-group">
<label for="password">Password</label>
<input type="text" class="form-control1" ng-model="passwordd"required id="password" />
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label for="username">Operator</label>
<input type="text" class="form-control1" ng-model="namee" required id="username" />
</div>
</div>
</div>
<button class="btn btn-primary" ng-click="createUser();" type="submit">Add user</button>
<!--<button class="btn btn-primary" ng-disabled="userForm.$invalid" type="submit">Добавяне на нов</button>-->
</form>
And Angular code:
$scope.createUser=function()
{
//console.log($scope.activeItem);
//delete $scope.activeItem.hash_method
var objectToSave = {
username: $scope.usernamee,
password: $scope.passwordd,
name: $scope.namee,
id: $scope.id
};
{
defaultAdapter.query('INSERT INTO users(username,password,name,id) VALUES(username = :usernamee, password = :passwordd,name = :namee WHERE id =:id)',
{ replacements: objectToSave, type: Sequelize.QueryTypes.UPDATE }
).then(projects => {
console.log(projects);
$scope.editMode = false;
$scope.activeItem = false;
$scope.refresh();
});
}
}

jQuery form validation fails only on a specific input

I have a fairly straightforward validation function that only checks if input is empty or not. I'm using it across a half dozen different forms and it seems to be working everywhere except one specific input id="driver_first_name" . Can't figure out why it fails there.
If I leave all fields empty I get errors on all of them, and is generally correct across any combination I have tried except driver_first_name In the case that I fill out everything except driver_first_name the form submits anyways.
Any insight on what might be going on here?
Thank you!
My Validation function is this:
function validateForm(form, fields) { //add exit anbimation and reset the container state
$(".form-input-error").remove();
var result=false;
$.each( fields.rules, function( key, value ) {
if(!$("#"+key+"").val()){
$("#"+key+"").addClass("form-error");
$( "<div class='form-input-error'>"+value.message+"</div>" ).insertBefore("#"+key+"");
result = false;
//console.log(this.val());
}
else{
$("#"+key+"").removeClass("form-error");
result = true;
}
});
return result;
}
I am calling my validation on my submit triggers, generally like this for fields that should not be empty:
$(".app-canvas").on('click', ".submitNewDriver", function () {//list all drivers trigger
var checkInputs = {
rules: {
driver_first_name: {
message: "First Name is Required"
},
driver_last_name: {
message: "Last Name is Required"
},
driver_address_street: {
message: "street is Required"
}
}
};
if(validateForm($("#addDriverForm"),checkInputs) == true){
console.log("form submit");
addNewDriver();
}
else{
console.log("form errors");
}
});
My full form HTML is

Your validation logic is a little messed up. This is what's happening:
#driver_first_name is validated as invalid... result is set false
#driver_last_name is validated as valid... result is set true
#driver_address_street is validated as valid... result is set true
After all that the code thinks the form is valid. You're only preventing the form from being submitted if the last field as validated as not-valid.
Change your logic to assume the form is valid from the beginning. Then set it to false if any of the fields are invalid.
I also don't see anything in your code that actually prevents the form submition, so I also added e.preventDefault()
function validateForm(form, fields) { //add exit anbimation and reset the container state
$(".form-input-error").remove();
var result = true;
$.each(fields.rules, function(key, value) {
if (!$("#" + key + "").val()) {
$("#" + key + "").addClass("form-error");
$("<div class='form-input-error'>" + value.message + "</div>").insertBefore("#" + key + "");
result = false;
//console.log(this.val());
} else {
$("#" + key + "").removeClass("form-error");
}
});
return result;
}
$(".app-canvas").on('click', ".submitNewDriver", function(e) { //list all drivers trigger
var checkInputs = {
rules: {
driver_first_name: {
message: "First Name is Required"
},
driver_last_name: {
message: "Last Name is Required"
},
driver_address_street: {
message: "street is Required"
}
}
};
if (validateForm($("#addDriverForm"), checkInputs) == true) {
console.log("form submit");
} else {
e.preventDefault();
console.log("form errors");
}
});

Convert mutlidimensional inputs to JavaScript object

I've been trying to solve this one for several days now and it's driving me nuts. I have some data that needs to be submitted by Ajax. It is dynamic, so I don't know how many fields it has. On top of that the names of the fields are multidimensional and also dynamic. For example one might have inputs with the name data[name] and data[title] whilst another larger one might have data[images][0][src], data[images][0][alt], data[images][0][description], data[images][1][src], data[images][1][alt], data[images][1][description] with an unknown number of elements to the array. My problem is that I need to get an object I can submit via Ajax whilst maintaining the structure of the data.
I've tried serialising the data, but that just comes up with a string of name = value. I've tried serialise array as well, but that just gives me an array of [name, value]. I've managed to generate the object manually using a regex to split it up, but I can't find a way to merge the resultant objects together. The latest version of my code is:
$('.modal-content').find('input[name^="data"]').each(function () {
var found = $(this).attr('name').match(re).reverse();
var temp = $(this).val();
$.each(found, function ()
{
str = this.substr(1, this.length - 2);
var t = {};
t[str] = temp;
temp = t;
});
data = $.each({}, data, temp);
});
Unfortunately it doesn't merge them, it overwrites what is in data with what is in temp. If data has data.images[0].src = "mysrc" and temp has data.images[0].alt = "myalt" then I just end up with data.images[0].alt = "myalt" and src is no longer there.
There has to be a simple way to do this, hell at this point I'd even take a complicated way to do this. Can someone please help me with this?

Although there is already an accepted answer. Here are my 5 cents:
IMHO working with regex should be avoided when possible. So my suggestion would be to change the HTML a bit, adding some classes to the div that contain the image and change the name attribute of the inputs:
<li class="col-xs-12 col-sm-6 col-md-4 col-lg-3 gallery-image ui-sortable-handle">
<div class="my-image">
<img src="http://localhost:8000/img/example.jpg">
<input type="hidden" name="src" value="img/example.jpg">
<div class="form-group">
<label for="title-0">Title:</label>
<input type="text" name="title" class="form-control" id="title-0" value="Default Example Image 1" placeholder="Title">
</div>
<div class="form-group">
<label for="description-0">Description:</label>
<input type="text" name="description" class="form-control" id="description-0" value="A default example image." placeholder="Description">
</div>
<div class="form-group">
<label for="alt-0">Alt tag (SEO):</label>
<input type="text" name="alt" class="form-control" id="alt-0" value="fluid gallery example image" placeholder="Alt tag">
</div>
<div class="form-group">
<label for="order-0">Order:</label>
<input type="number" name="order" class="form-control image-order" id="order-0" value="0">
</div>
<button type="button" class="btn btn-danger remove-gallery-image-btn">× Delete</button>
</div>
</li>
<li class="col-xs-12 col-sm-6 col-md-4 col-lg-3 gallery-image ui-sortable-handle">
<div class="my-image">
<img src="http://localhost:8000/img/example.jpg">
<input type="hidden" name="src" value="img/example.jpg">
<div class="form-group">
<label for="title-1">Title:</label>
<input type="text" name="title" class="form-control" id="title-1" value="Default Example Image 2" placeholder="Title">
</div>
<div class="form-group">
<label for="description-1">Description:</label>
<input type="text" name="description" class="form-control" id="description-1" value="A default example image." placeholder="Description">
</div>
<div class="form-group">
<label for="alt-1">Alt tag (SEO):</label>
<input type="text" name="alt" class="form-control" id="alt-1" value="fluid gallery example image" placeholder="Alt tag">
</div>
<div class="form-group">
<label for="order-1">Order:</label>
<input type="number" name="order" class="form-control image-order" id="order-1" value="1">
</div>
<button type="button" class="btn btn-danger remove-gallery-image-btn">× Delete</button>
</div>
</li>
Then build the object matching this class:
var obj = {
data: {
images: []
}
}
var groups = $('.my-image');
groups.each(function(idx, el) {
var child = {}
$(el).find('input').each(function(jdx, info){
var $info = $(info);
child[$info.attr('name')] = $info.val();
});
obj.data.images.push(child);
});
We would have the same result, but it might be less error prone. Here is a plunker.

You can loop all inputs with each() loop, create array from name attributes using split() and then use reduce to add to object
var result = {}
$('input').each(function() {
var name = $(this).attr('name');
var val = $(this).val();
var ar = name.split(/\[(.*?)\]/gi).filter(e => e != '');
ar.reduce(function(a, b, i) {
return (i != (ar.length - 1)) ? a[b] || (a[b] = {}) : a[b] = val;
}, result)
})
console.log(result)

dynamically add form in HTML

I'm trying to code this form in sharing.html so that when one is done putting in information and want to add more contacts, they can click on "add another contact" but when I tried to write out the code, the dreamweaver I was using said that there's a error in Javascript. I don't know how I can fix this error: (the script is almost at the bottom)
<div class="recordsbox">
<h1>Sharing Center</h1>
<p>Please enter the contact information that you want to share.</p>

</div>
<div class="notifyfield">
<label>Email Address:</label>
<input type="email" >
</div>
<div class="notifyfield">
<label>Phone Number:</label>
<input type="tel" >
</div>
</form>
</div>
';
document.getElementById(divName).appendChild(newform);
shareform++;
}
</script>
<div class="nextbutton">
Next
</div>
</div>
I based this code on that tutorial: http://www.randomsnippets.com/2008/02/21/how-to-dynamically-add-form-elements-via-javascript/.
Also you can check out full code at http://hamzakhan.name/dev/eric/options_innerpage/sharing.html
For a quicker look, here is the script in question:
<script>
var shareform = 0;
function addForm(divName) {
shareform++;
var newform = document.createElement('div');
newform.innerHTML = '<div id="shareform'+shareform+'">
<form id="share" method="POST">
<div class="notifyfield">
<label>Who is this person?</label>
<input type="text">
</div>
<div class="notifyfield">
<label>Email Address:</label>
<input type="email" >
</div>
<div class="notifyfield">
<label>Phone Number:</label>
<input type="tel" >
</div>
</form>
</div>
';
document.getElementById(divName).appendChild(newform);
shareform++;
}
</script>

Here is the new code:
var shareform = 0;
function addForm(divName) {
shareform++;
var newform = document.createElement('div');
newform.innerHTML = '<div id="shareform'+shareform+'"><form id="share" method="POST"><div class="notifyfield2"><div class="sharefield"><label>Who is this person?</label><input type="text"></div></div><div class="notifyfield"><label>Email Address:</label><input type="email" ></div><div class="notifyfield"><label>Phone Number:</label><input type="tel" ></div></form><hr class="greenline"></div>';
document.getElementById(divName).appendChild(newform);
shareform++;
}
You need to delete all invisible characters. You can't "newline" string.

Javascript hide/show questions depending on user input values

I am trying to hide and/or show form elements when a user selects certain values.
For example, if the user selects "yes" to the consent question, I need it to show a few questions, However, if they change their response to the consent question, I need it to hide those questions.
Here is what I have come up with so far...
$(document).ready(function () {
var input = document.getElementById('consent');
var consent_responses = [{ "0": hideConsent },{ "1": showConsent }];
input.addEventListner('click', function () {
var consent_response;
if (consent_responses[this.value]) {
content_response = consent_responses[this.Function()]
}
else {
content_response = consent_responses[this.Function]
}
});
function showConsent(){
$("#date").show(),
$("#referrer").show(),
$("#f_name").show(),
$("#phone_num").show(),
$("#leave_msg").show(),
$("#email").show(),
};
function hideConsent(){
$("#date").hide(),
$("#referrer").hide(),
$("#f_name").hide(),
$("#phone_num").hide(),
$("#leave_msg").hide(),
$("#email").hide(),
}; });

You could do it like this: JSFiddle
Basically I only fixed a few typos (did you actually try your code before you posted here?) and added event listeners to the radio buttons with
document.getElementById(...).addEventListener(...)
I also gave your radio buttons unique IDs.

This can be simplified:
var input = document.getElementById('consent');
// Let's use the value as key, and the functions as values
var consent_responses = {
"0" : hideConsent,
"1" : showConsent
};
input.addEventListener("click", function () {
// Get the appropriate function given the value, and invoke it
consent_responses[this.value]();
});
function hideConsent() {
// ...
}
function showConsent() {
// ...
}

It's better to envelop your questions (that needs to be hidden) by a div with a class ".hidden" or style "display: none;". And simplify your code by simply asking that div to show() or hide() when needed.
Like so:
<form id="screening">
<div class="col-md-12 col-sm-12 col-xs-12 nopad" id="create">
<div class="form-group text-center">
<b>Do you agree to answer the screening questions?</b><br />
<div class="radio" id="consent">
<label>
<input type="radio" name="consent" id="consent" value="1">
Yes, I consent
</label>
</div><br />
<div class="radio">
<label>
<input type="radio" name="consent" id="consent" value="0">
No, I do not consent
</label>
</div>
</div>
<!-- simplify by using this -->
<div id="questions" style="display: none;">
<div class="form-group" id="date">
<label for="date">What is today's date?</label>
<input type="date" class="form-control" id="date" name="date" />
</div>
<div class="form-group" id="referrer">
<label for="referrer">How did you hear about us/our studies?</label>
<select class="form-control" name="referrer" id="referrer">
<option></option>
<option value="1">Flyers</option>
<option value="2">Print Media</option>
<option value="3">A friend</option>
<option value="4">Online (e.g., Craigslist)</option>
<option value="5">Other</option>
</select>
</div>
<div class="form-group" id="other_explain">
<label for="other_explain">Please specify other source.</label>
<textarea class="form-control" rows="3" id="other_explain" name="other_explain"></textarea>
</div>
<div class="form-group" id="f_name">
<label for="f_name">What is your first name?</label>
<input type="text" class="form-control" id="f_name" name="f_name" />
</div>
<div class="form-group" id="phone_num">
<label for="phone_num">What is a phone number at which you can be contacted? </label>
<input type="tel" class="form-control" id="phone_num" name="phone_num" />
</div>
<div class="form-group" id="leave_msg">
<label for="leave_msg">If we call and you are not available, may we leave a message?</label><br />
<div class="radio">
<label>
<input type="radio" name="leave_msg" id="leave_msg" value="1">
Yes
</label>
</div><br />
<div class="radio">
<label>
<input type="radio" name="leave_msg" id="leave_msg" value="0">
No
</label>
</div>
</div>
<div class="form-group" id="email">
<label for="email">What is an e-mail at which you can be contacted?</label>
<input type="email" class="form-control" id="email" name="email" />
</div>
</div>
</div>
</form>
and in your javascript instead of using this:
function showConsent(){
$("#date").show(),
$("#referrer").show(),
$("#f_name").show(),
$("#phone_num").show(),
$("#leave_msg").show(),
$("#email").show(),
};
you use:
function showConsent(){
$("#questions").show(),
};
