C# Submitting http post request to fill a form

I am trying to submit a form using C# to my website. On my website I have a petition form where I have a few text boxes and a submit button, I can do this completely fine on the browser, but I want to do it from C#.
Here is the following javascript code it's very simple:
(function($) {
"use strict";
var $button = $('#sign-petition');
$button.submit(function(e){
e.preventDefault();
var $country = '';
var $state = '';
var $zip = '';
var $city = '';
var $terms = '';
var $newsletter = 0;
var $bio = '';
if( $( 'select[name="country"]', this ).length > 0 ) {
$country = $( 'select[name="country"]', this ).val();
}
if( $( 'input[name="state"]', this ).length > 0 ) {
$state = $( 'input[name="state"]', this ).val();
}
if( $( 'input[name="zip"]', this ).length > 0 ) {
$zip = $( 'input[name="zip"]', this ).val();
}
if( $( 'input[name="city"]', this ).length > 0 ) {
$city = $( 'input[name="city"]', this ).val();
}
if( $( 'input[name="terms"]', this ).length > 0 ) {
if( $( 'input[name="terms"]', this ).prop('checked') ){
$terms = $( 'input[name="terms"]', this ).val();
}
}
if( $( 'input[name="newsletter"]', this ).length > 0 ) {
if( $( 'input[name="newsletter"]', this ).prop('checked') ){
$newsletter = 1;
}
}
if( $( 'textarea.bio', this ).length > 0 ) {
$bio = $( 'textarea.bio', this ).val();
}
var data = {
'action': 'sign_petition',
'email' : $( 'input[name="email"]', this ).val(),
'fname' : $( 'input[name="fname"]', this ).val(),
'lname' : $( 'input[name="lname"]', this ).val(),
'bio' : $bio,
'signature' : $( '#signature', this ).val(),
'country' : $country,
'state' : $state,
'zip' : $zip,
'city' : $city,
'terms' : $terms,
'newsletter' : $newsletter
};
$.post( petition.ajaxurl, data, function( response ) {
//console.log(response);
response = JSON.parse(response);
if( typeof(response.errors) !== "undefined" && response.errors !== null ){
if( $( '#petition-errors' ).html() !== '' ){ $( '#petition-errors' ).html(''); }
$('#sign-petition .error').each(function (){
$(this).removeClass('error');
});
$.each( response.errors, function( key, error ){
$( '.' + key, '#sign-petition' ).addClass( 'error' );
$( '#petition-errors' ).append( '<li>' + error[0] + '</li>' );
});
} else{
$( '<p>' + response.success + '</p>' ).insertBefore( '#sign-petition' );
$('#sign-petition').hide();
}
});
});
})(jQuery);
I've used Microsoft's provided example and this is what i have so far, but it's not working.
string uriString = "https://example.org/";
// Create a new WebClient instance.
WebClient myWebClient = new WebClient();
// Create a new NameValueCollection instance to hold some custom parameters to be posted to the URL.
NameValueCollection myNameValueCollection = new NameValueCollection();
myNameValueCollection.Add("signature", "15c8c9a392");
myNameValueCollection.Add("email", "tom#appleseed.com");
myNameValueCollection.Add("fname", "Tom");
myNameValueCollection.Add("lname", "Appleseed");
myNameValueCollection.Add("country", "US");
myNameValueCollection.Add("state", "WA");
myNameValueCollection.Add("zip", "98174");
myNameValueCollection.Add("city", "Seattle");
var responseArray = myWebClient.UploadValues(uriString, myNameValueCollection);
var response = Encoding.ASCII.GetString(responseArray);
var outputFilePath = Environment.CurrentDirectory + "\\petition\\" + DateTime.Now.ToString("yyyy-MM-dd--HH-mm-ss") + ".html";
try
{
File.WriteAllText(outputFilePath, response);
}
catch (Exception e) { Console.WriteLine(e); }
Also here is the html code:
<form id="sign-petition" method="post">
<input type="hidden" id="signature" name="signature" value="15c8c9a392">
<input type="hidden" name="_wp_http_referer" value="/">

<option value="US" label="United States">United States</option>
</select>
</div>
<div class="form-group">

<textarea class="form-control bio" placeholder="comments" rows="3"></textarea>
</div>
<ul id="petition-errors"></ul>
<button type="submit" class="btn btn-primary">Sign Petition!</button>
</form>
Any help is appreciated
Thanks.

What about using an HttpClient and just posting the data? Something like this.
var data = new
{
action = "sign_petition",
signature = "15c8c9a392",
email = "tom.appleseed.com",
fname = "Tom",
lname = "Appleseed",
country = "US",
state = "WA",
zip = "98174",
city = "Seattle"
};
using (var client = new HttpClient())
{
var uriString = "https://example.org";
var result = client.PostAsync(uriString, new StringContent(JsonConvert.SerializeObject(data), Encoding.UTF8, "application/json")).Result;
if (!result.IsSuccessStatusCode)
{
//Handle the error
}
else
{
//Do something else
}
}

How to retrieve old text and subtract from total - JS

This is a follow up question on an existing question. I am able to get total sub-price tof products that i selected and add up to get the grand total. Now, when an item is deselected, i want to subtract the price of the item being deselected from the existing grand total?
How do i get that done please?
When i try to get the oldtext, it is always 0 .. why is this happening?
HTML
<div class="panel" id="panel">
<div>
<div >
<p> class="mygoods" >Total: <span ></span></p>
</div>
JS
<script type="text/javascript">
function order(food)
{
var ad = JSON.parse(food.dataset.food);
if(food.checked == true) {
$('.panel').append(
'<div class="container" style=" font-size:14px; "> '+
'<p class="total" ><span class="sub-total" name="total" id="total"></span></p>'+
'<input size="50" type="text" class="form-control quantity" id="qty" placeholder=" qty " name="quantity[]" required/>'+
'</div>'
)
}
else{
var total = $(".panel .container [data-id=" + ad.id + "]").parent().find(".total").text();
$(".panel .container [data-id=" + ad.id + "]").parent().remove();
if (total) {
$('.mygoods span').text(function(oldtext) {
console.log('this is my old text '+oldtext)
return oldtext ? oldtext - total : oldtext;
});
}
}
}
$('.panel').on('keyup','.quantity',function()
{
var sum;
container = $(this).closest('div');
quantity = Number($(this).val());
price = Number($(this).closest('div').find('.price').data('price'));
container.find(".total span").text(quantity * price);
sum = 0;
$(".sub-total").each(function(){
sum = sum + Number($(this).text());
})
$('.mygoods span').text(sum);
});
</script>

$( '.mygoods span' ).text( function( oldtext ) {
console.log( 'this is my old text ' + oldtext )
return oldtext ? oldtext - total : oldtext;
} );
the .text method returns the parameters index and text - you only are retrieving one. Therefore the index is being stored in the oldtext variable, not the text.
Type: Function( Integer index, String text ) => String A function
returning the text content to set. Receives the index position of the
element in the set and the old text value as arguments.
http://api.jquery.com/text/
You can fix this by simply adding another parameter.
$( '.mygoods span' ).text( function(index, oldtext ) {
console.log( 'this is my old text ' + oldtext )
return oldtext ? oldtext - total : oldtext;
} );
I tried copying a snippet over to show you, but the code you provided is not enough to build anything. The attempted build is below.
function order( food ) {
var ad = JSON.parse( food.dataset.food );
if ( food.checked == true ) {
$( '.panel' ).append( '<div class="container" style=" font-size:14px; "> ' +
'<p class="total" ><span class="sub-total" name="total" id="total"></span></p>' +
'<input size="50" type="text" class="form-control quantity" id="qty" placeholder=" qty " name="quantity[]" required/>' +
'</div>' )
} else {
var total = $( ".panel .container [data-id=" + ad.id + "]" ).parent().find(
".total" ).text();
$( ".panel .container [data-id=" + ad.id + "]" ).parent().remove();
if ( total ) {
$( '.mygoods span' ).text( function( index, oldtext ) {
console.log( 'this is my old text ' + oldtext )
return oldtext ? oldtext - total : oldtext;
} );
}
}
}
$( '.panel' ).on( 'keyup', '.quantity', function() {
var sum;
container = $( this ).closest( 'div' );
quantity = Number( $( this ).val() );
price = Number( $( this ).closest( 'div' ).find( '.price' ).data( 'price' ) );
container.find( ".total span" ).text( quantity * price );
sum = 0;
$( ".sub-total" ).each( function() {
sum = sum + Number( $( this ).text() );
} )
$( '.mygoods span' ).text( sum );
} );

javascript Alert to confirm if value entered twice

I have a form:
// 10 times
<input type="text" name="cityname" class="autocompletecity">
<input type="text" name="cityID" class="autocompletecityID">
When I enter the city name, it autocompletes the city name and the cityID from database with this code:
<?php for ($i = 0; $i < 10; $i++) { /*in the field class add $i */ ?>
$(function() {
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 1 );
}
$( ".autocompletecity<?php echo $i ?>" ).autocomplete({
source: "/*path to json*/",
select: function( event, ui ) {
var item = ui.item;
if(item) {
$(".autocompletecityID<?php echo $i ?>").val(item.cityID);
$(this).val(item.value +' ' + item.country);
return false;
}
}
//code from J.D.
select: function( event, ui ) {
var item = ui.item;
if(item) {
$('input[name="cityID"]').each(function(index, element) {
var $element = $(element);
if ($element.value() == item.cityID) {
alert('This city has already been selected');
}
});
}
}
})
.autocomplete( "instance" )._renderItem = function( ul, item ) {
return $( "<li>" )
.append( "<a>" +item.value + " " +item.country + "</a>" )
.appendTo( ul );
};
});
<?php } ?>
After it autocompletes the cityID, I would like to show an alert box if same cityID has alredy been entered: Click OK to confirm or Cancel to clear the cityname and cityID with repeated entry.
I tried to search in the jqueryui, but no luck...
Thanks!!

Try this:
select: function( event, ui ) {
var item = ui.item;
if(item) {
$('input[name="cityID"]').each(function(index) {
var $element = $(this);
if ($element.value() == item.cityID) {
alert('This city has already been selected');
}
});
}
}

Uncaught TypeError: undefined is not a function

I am newbie to js, I have copied a script from jqueryui.com for the dialog widget and pasted it in my Yii project, but I got an error: Uncaught TypeError: undefined is not a function, which is the function of $( "#dialog-form" ).dialog, so what is the error, and how I can fix it, here is the code:

Did you include something like
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"></script>

the problem is solved, its because I loaded a default jquery package instead of the customized Jquery package that contains the dialog widget.

Js/jQuery - How to hide/show an input created on the fly?

This code creates a group of elements (four inputs) on the fly. Once you create an element (four inputs) you can select/deselect, when you select an element will bring up the editor for the corresponding element. I've made a function to hide only the first element. The problem is that I can not make it comeback without affecting the other elements.
Instructions:
Click on the "Price" link, an element will be created on the fly (four nested inputs)
Select the element (four nested inputs) to bring up the editor ( one input and a brown little square).
Click on the little brown square to hide the first input of the element (four nested inputs) and that will hide the first input.
I need the little brown square to hide and show the same input.
Go here to see the full code:
To see the problem you have to create more than one element to find out.

This is the JS/jQuery code, for the full code go to the link above.

.appendTo(list).children('.n').text(num)
.siblings('.p').text(set.val());
set.val('');
}
