Stripe implementation in my own form in an Express app

I'm trying to get some value(total = total + itemJson.price * item.quantity) into my own form for stripe.
Every time I try to submit I get this error message:
"$ node server.js
C:\Users\Marcio\dsdrucker1\server.js:44 req.body.items.forEach(function(item) {
^
TypeError: Cannot read property 'forEach' of undefined
at C:\Users\Marcio\dsdrucker1\server.js:44:22
at FSReqCallback.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:63:3)".
Here below you can find my code I have written. What am I doing wrong?
app.post('/checkout', function(req, res) {
fs.readFile('items.json', function(error, data) {
if (error) {
res.status(500).end()
} else {
const itemsJson = JSON.parse(data)
const itemsArray = itemsJson.roupa
let total = 0
req.body.items.forEach(function(item) {
const itemJson = itemsArray.find(function(i) {
return i.id == item.id
})
total = total + itemJson.price * item.quantity
})
stripe.charges.create({
amount: total,
source: req.body.stripeTokenId,
currency: 'usd'
}).then(function() {
console.log('Charge Successful')
res.json({ message: 'Successfully purchased items' })
}).catch(function() {
console.log('Charge Fail')
res.status(500).end()
})
}
})
})

How to collect all value from HTML form?

I'm currently trying to use jQuery to collect information from a HTML form, but I'm stuck.
Every time I console.log payload its empty and didn't capture the input values.
Questions:
Why is payload empty at the end, after I input values into the form?
how to correct it?
Should I use document.ready for this or window.onload?
Please any help is appreciated.
Here is my last attempt jQuery:
$(document).ready(function() {
const ApplyOpeningPayloadBuilder = function() {
let payload = {
"fields": []
};
return {
withKeyValue: function(key, value) {
let param = {};
param.key = key;
param.value = value;
payload.fields.push(param);
return this;
},
withFile: function(key, encoded_data, filename) {
let value = {};
value.encoded_data = encoded_data;
value.file_name = filename;
this.withKeyValue(key, value);
return this;
},
build: function() {
return payload;
}
}
}
let encoded_file = "aGVsbG8gd29ybGQ=";
let apply_for_an_opening_payload_builder = new ApplyOpeningPayloadBuilder();
$(".applicantForm input[type=text]").each(function() {
apply_for_an_opening_payload_builder.withKeyValue(this.name, this.value);
});
$(".applicantForm input[type=email]").each(function() {
apply_for_an_opening_payload_builder.withKeyValue(this.name, this.value);
});
$(".applicantForm input[type=tel]").each(function() {
apply_for_an_opening_payload_builder.withKeyValue(this.name, this.value);
});
$(".applicantForm input[type=url]").each(function() {
apply_for_an_opening_payload_builder.withKeyValue(this.name, this.value);
});
apply_for_an_opening_payload_builder.withFile("resume", encoded_file, "resume.txt");
let payload = apply_for_an_opening_payload_builder.build();
console.log("Log payload:", payload)
});

Here is the structure of how the payload object should look like in the end:
let payload = {
"fields": [
{ "key" : "candidate_first_name", "value" : "John"},
{ "key" : "candidate_last_name", "value" : "Doe"},
{ "key" : "candidate_email", "value" : "john.doe#gmail.com"},
{ "key" : "candidate_phone", "value" : "1234567890"},
{ "key" : "resume", "value": {
"encoded_data" : "aGVsbG8gd29ybGQ=",
"file_name" : "resume.txt"
}
}
]
};
Note the payload structure is from this link, specifically the "Apply for a Opening" section.

You are running all the code at once (document.ready()), instead you need to run it inside form submit, like $('.applicantForm').on('submit', function(e){}).
Check the updated fiddle
var $ = jQuery;
$(document).ready(function() {
const ApplyOpeningPayloadBuilder = function() {
let payload = {

this.withKeyValue(key, value);
return this;
},
build: function() {
return payload;
}
}
}
let encoded_file = "aGVsbG8gd29ybGQ=";
$('.applicantForm').on('submit', function(e) {

Also, i want to know how i can send the value to my controller using ajax so that i can send it to model.

Unable to create array of object to save MongoDB from AngularJS

I have created html dynamically and want to save in MongoDB using Mongoose from AngularJS. But the problem is that, I'm unable to create that require object which I have created Mongoose schema.
model code
var SegmentSchema = new Schema({
name: String,
uiName:String,
type:String,
lower:Number,
upper:Number,
options:[{key:String,value:String}]
});
export default mongoose.model('Segment', SegmentSchema);
view code
<form class="form-horizontal" ng-submit="addSegment()">
<div class="form-group">
<label class="col-sm-2 control-label">Name</label>
<div class="col-sm-6">

<div class="form-group">

</form>
angularjs(controller) code:
angular.module('nrichApp')
.controller('SegmentCtrl', function ($scope,$http,segment) {
$scope.loading = true;
$scope.addSegmentDiv=false;
segment.get().success(function(data) {
$scope.segments=data;
});
$scope.loading = false;
})
.controller('AddSegmentCtrl', function ($scope,segment,$location,$compile) {
$scope.loading = true;
$scope.addSegmentBtn=false;
$scope.changeType=function(){
$scope.addSegmentBtn=true;
$scope.rangeShow=false;
$scope.selectOptionShow=false;
$scope.numOptionShow=false;
switch ($scope.segment.type) {
case 'range':

input+='<div class="form-group">';

}
var eleDiv=angular.element(document.querySelector('#segment-select-option'));
eleDiv.html(input);
$compile(eleDiv)($scope);
};
$scope.addSegment=function(){
$scope.loading = true;
var param = {'segment' : $scope.segment};
console.log(JSON.stringify(param));//it is output which show at below
segment.create(param)
.success(function(data) {
$scope.loading = false;
$location.path('/segment');
});
$scope.loading = false;
};
});
Output:
{
"segment":{
"type":"select",
"name":"range2",
"uiName":"Select 3",
"options":{
"0": { "key":"k3","value":"v2"},
"1": { "key":"k4","value":"v4"}
}
}
}
Desired Output:
{
"segment": {
"type":"select",
"name":"range2",
"uiName":"Select 3",
"options": [
{"key":"k3","value":"v2"},
{"key":"k4","value":"v4"}
]
}
}

Finally, i got solution. I just declare array data type for options variable i.e,
$scope.options=[]
Inside angular controller:
$scope.keyupOptionNumber=function(){
$scope.options=[];//Here, this line is missing
console.log($scope.numOption);
$scope.selectOptionShow=true;
var input ='';
for (var i = 0; i < $scope.numOption; i++) {
input+='<div class="form-group">';
input+='<label for="option_key" class="col-sm-2 control-label">Key</label>';
input+='<div class="col-sm-2"><input ng-model="segment.options[' + i + '].key" class="form-control" type="text" name="key" value=""></div>';
input+='<label for="option_value" class="col-sm-1 control-label">Value</label>';
input+='<div class="col-sm-3"><input ng-model="segment.options[' + i + '].value" class="form-control" type="text" name="value" value=""></div>';
input+='</div>';
}
var eleDiv=angular.element(document.querySelector('#segment-select-option'));
eleDiv.html(input);
$compile(eleDiv)($scope);
};

How to populate this form data and post it with jquery

I have a html form as follows:-
<form class="form-horizontal" role="form" method="post" action="" id="scheduler_form">{%csrf_token%}
<div class="form-group">

<button type="button" class="btn btn-default pull-right closediv" data-dismiss="setup_blk" aria-label="Close">CANCEL</button>
</form>
I have a generic method to make an Ajax call.
function makeAJAXRequest(_uri, _method, _data, _contenttype, _datatype, _context, _processdata, _successHandler, _errorHandler){
var _jqXHR = $.ajax({
url: _uri,
type: _method,
data: _data,
contentType: _contenttype,
dataType: _datatype,
context: _context,
processData: _processdata,
cache: true
});
_jqXHR.done( _successHandler );
_jqXHR.fail( _errorHandler );
}
Now I am binding create_schedule button as follows.
$('#create_schedule').on('click', function (event) {
// Call a function createScheduler to build json data for AJAX - POST call and get response.
createScheduler();
});
function createScheduler() {
var _schedulerData = {};
$.each($('#scheduler_form'), function () {
_schedulerData[this.name] = this.value;
console.log(_schedulerData);
});
makeAJAXRequest(
API_SCHEDULE,
'post', _schedulerData,
'',
'json', {},
true,
createUserScheduleSuccessHandler,
createUserScheduleErrorHandler);
function createUserScheduleSuccessHandler(_data) {
console.log(_data);
}
function createUserScheduleErrorHandler(jqXHR, textStatus, errorThrown) {
console.log('Error')
}
}
Now I am getting confused as how to populate the form data and make the post request. Any help here.

Change
<button type="submit" class="btn btn-warning pull-right" .... >
To
<button type="button" class="btn btn-warning pull-right" .....>
OR:
you can call the prevenDefault method when button click fired.
event.preventDefault();
console.log( $( '.form-horizontal' ).serialize() );
serializing the form will get all the data from form controls.
