Problem with recaptcha3 for .NET MVC website

I'm quite new in web development, have only couple of weeks of experience.
Currently working on C# website and can't get ReCaptchaV3 to work.
I have a subscribe form that shows up as a modal when user clicks on a "subscribe" button on the bulletin page.
In the form I have hidden input field: <input type="hidden" name="Google-captcha-token" id="GoogleCaptchaToken">
It generates the token when "Sign Up" button of the form is clicked.
My problem is - how to I get a hold of that value on the backend in C#? and then send it to google for verification? I also need to check if value I got from Google is within needed range and everything is good continue submitting the form.
This is where I stuck. I understand that I need to catch that value and work with it in the controller, but don't know how to do that.
Hope someone can help me out on this one.
This is how the code in the controller looks
public class BulletinController : _SharedController {
public ActionResult Index(int p = 0) {
var perPage = 10;
if (p < 1) {
p = 1;
}
var starting = (p * perPage) - perPage;
if (starting < 0) {
starting = 0;
}
var token = HttpContext.Request.Form["Google-captcha-token"];
var ns = new NewsServices();
var newsArticles = ns.GetNewsArticles(starting, perPage);
var count = ns.GetNewsArticlesCount();
ViewBag.Paging = Pagination.Generate(count, starting, perPage);
return View(newsArticles);
}
public ActionResult Details(int id) {
var article = new NewsServices().GetNewsArticleByID(id);
if (article == null) {
return HttpNotFound();
}
return View(article);
}
}
I watched a lot of videos on how it should be done, but none of them worked.
It seems to be a problem that view of the page is already using a model and that model is autogenerated. So looks like I can't use another model. Current model is also a list model (not sure what that exactly means though).
The other thing is that submission of the form is not going through the back-end and done through the constantcontact JavaScript sign up script.
Hope somebody will be able to help. Thanks.

How to get the page of an item of Kendo Grid using ServerOperation

I'm trying to retrieve the page index of a selected object of the grid that is using ServerOperation, but I don't know how would I do that without too much complication.
Currently, I'm receiving an Id from the URL (https://...?ObjectId=12) and I will select this item in the grid, but first I have to show the page it is, so I'm trying to get the page number of this row.
The problem is that I'm using ServerOperation(true). In addition, I'm retrieving the paged list without any filters.
function _displayDetailsModal(id, selectRow = true, focusSelected = true) {
$(document).ready(() => {
var url = `${urls.Details}/${id}`;
if (selectRow) {
// GET PAGE OF ITEM THEN
// CHANGE TO PAGE THEN
kendoGrid.selectById(id);
}
if (focusSelected) {
kendoGrid.focusSelected(); // Scrolls to selected row.
}
loadModal(url);
});
}

Is this the kind of thing you are after?
Dojo: https://dojo.telerik.com/iNEViDIm/2
I have provided a simple input field where you can set the page number and then a button which will change the page to the selected page for you.
All I am doing is setting the datasource's page via the page method and then it will go off and make a read to the remote datasource for you and then return that page of data.
$('#btnPage').on('click',function(e){
var page = $('#pageNumber').val();
$('#pageLabel').html('Page Selected Is: ' + page);
var ds = $('#grid').data('kendoGrid').dataSource;
ds.page(parseInt(page));
});
If you select a page higher than the last available then it will just show the last page.
More info can be seen here: https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/page
If you need any further info let me know:

I ended up doing it on the server. That is how I did it:
Controller.cs
Instead of sending just the usual ToDataSourceResult, I add two fiels (PageIndex and ObjectId), and send it to the front-end to change the page and select the row.
[HttpPost("List")]
public IActionResult List([DataSourceRequest] DataSourceRequest request, RequestActionViewModel requestAction)
{
// Getting the pageIndex of the ObjectId present in requestAction.
var objectIndex = elementList.FindIndex(el => el.Id == requestAction.ObjectId) + 1;
var objectPageIndex = Math.Ceiling((decimal)objectIndex / request.PageSize);
var dataSourceResult = elementList.ToDataSourceResult(request);
return Json(new {
Data = dataSourceResult.Data,
Total = dataSourceResult.Total,
AggregateResults = dataSourceResult.AggregateResults,
Errors = dataSourceResult.Errors,
// Extra fields
PageIndex = objectPageIndex,
ObjectId = requestAction.ObjectId
});
}
index.js
I Get from the server the page and the id of the element, select the change the page of the grid, and select the element.
function onGridRequestEnd(e) {
this.unbind("requestEnd", onGridRequestEnd);
if (e.PageIndex) {
kendoGrid.bind("dataBound", function temp() {
// Custom method.
kendoGrid.selectById(e.ObjectId, e.PageIndex);
// To avoid looping.
kendoGrid.unbind("dataBound", temp);
});
}
}

Jquery Chosen plugin. Select multiple of the same option

I'm using the chosen plugin to build multiple select input fields. See an example here: http://harvesthq.github.io/chosen/#multiple-select
The default behavior disables an option if it has already been selected. In the example above, if you were to select "Afghanistan", it would be greyed out in the drop-down menu, thus disallowing you from selecting it a second time.
I need to be able to select the same option more than once. Is there any setting in the plugin or manual override I can add that will allow for this?

I created a version of chosen that allows you to select the same item multiple times, and even sends those multiple entries to the server as POST variables. Here's how you can do it (fairly easily, I think):
(Tip: Use a search function in chosen.jquery.js to find these lines)
Change:
this.is_multiple = this.form_field.multiple;
To:
this.is_multiple = this.form_field.multiple;
this.allows_duplicates = this.options.allow_duplicates;
Change:
classes.push("result-selected");
To:
if (this.allows_duplicates) {
classes.push("active-result");
} else {
classes.push("result-selected");
}
Change:
this.form_field.options[item.options_index].selected = true;
To:
if (this.allows_duplicates && this.form_field.options[item.options_index].selected == true) {
$('<input>').attr({type:'hidden',name:this.form_field.name,value:this.form_field.options[item.options_index].value}).appendTo($(this.form_field).parent());
} else {
this.form_field.options[item.options_index].selected = true;
}
Then, when calling chosen(), make sure to include the allows_duplicates option:
$("mySelect").chosen({allow_duplicates: true})

For a workaround, use the below code on each selection (in select event) or while popup opened:
$(".chosen-results .result-selected").addClass("active-result").removeClass("result-selected");
The above code removes the result-selected class and added the active-result class on the li items. So each selected item is considered as the active result, now you can select that item again.

#adam's Answer is working very well but doesn't cover the situation that someone wants to delete some options.
So to have this functionality, alongside with Adam's tweaks you need to add this code too at:
Chosen.prototype.result_deselect = function (pos) {
var result_data;
result_data = this.results_data[pos];
// If config duplicates is enabled
if (this.allows_duplicates) {
//find fields name
var $nameField = $(this.form_field).attr('name');
// search for hidden input with same name and value of the one we are trying to delete
var $duplicateVals = $('input[type="hidden"][name="' + $nameField + '"][value="' + this.form_field.options[result_data.options_index].value + '"]');
//if we find one. we delete it and stop the rest of the function
if ($duplicateVals.length > 0) {
$duplicateVals[0].remove();
return true;
}
}

angularj ui grid searching

I'm looking for tutorial or example on how to implement a simple input text for searching
in the grid.
My attempt (but ng-keyup require angularjs > 1.1.3 and I've got
1.0.7)
<input type="text" ng-keyup="mySearch()" ng-model="searchText">
$scope.getPagedDataAsync = function (pageSize, page, searchText) {
setTimeout(function () {
var data;
if (searchText) {
var ft = searchText.toLowerCase();
$http.get('largeLoad.json?q='+encodeURIComponent(ft)).success(function (largeLoad) {
$scope.setPagingData(largeLoad,page,pageSize);
});
} else {
$http.get('largeLoad.json').success(function (largeLoad) {
$scope.setPagingData(largeLoad,page,pageSize);
});
}
}, 100);
};
$scope.mySearch = function(){
console.log($scope.searchText);
$scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage,$scope.searchText);
}
Bye
NB its a fake request against a json file just to make the example.
Update: I'm using ng-grid-1.3.2

Basically to solve this problem I think you can use a solution similar to what I've done below where I'm just watching the property of the model for changes and firing a function to do the filtering on the data set at that point.
The HTML for the text input
<input type="text" placeholder="Type to filter" ng-model="gardenModel.externalFilterText"/>
The JavaScript that filters the data set (also included the part I had a watch on a service to update the data in the first place too or if the data is refreshed to reapply the filter).
//This function is called every time the data is updated from the service or the filter text changes
$scope.filterGardens = function(filterText) {
//Basically everything in this function is custom filtering specific
//to the data set I was looking at if you want something closer to the
//real implementation you'll probably have to dig through the source (I believe they separated the search filter code into it's own file in the original project)
//Creating a temporary array so changes don't cause a bunch of firing of watchers
var tempToShow = [];
//doing case insensitive search so lower case the filter text
filterText = filterText.toLowerCase();
//If the filter text is blank just use the whole data set
if(!filterText || filterText == "")
{
$scope.gardenModel.shownGardens = $scope.gardenModel.gardens;
return;
}
//step through each entry in the main list and add any gardens that match
for (var i = 0; i < $scope.gardenModel.gardens.length; i++) {
var curEntry = $scope.gardenModel.gardens[i];
var curGarden = curEntry.curGarden;
if(curGarden["Garden Name"] && curGarden["Garden Name"].answer.toString().toLowerCase().indexOf(filterText)!=-1)
tempToShow.push(curEntry);
else if(curGarden["Address"] && curGarden["Address"].answer.toString().toLowerCase().indexOf(filterText)!=-1)
tempToShow.push(curEntry);
else if(curGarden["Ownership"] && curGarden["Ownership"].answer.toString().toLowerCase().indexOf(filterText)!=-1)
tempToShow.push(curEntry);
else if(curGarden.gardenId && curGarden.gardenId == filterText)
tempToShow.push(curEntry);
};
$scope.gardenModel.shownGardens = tempToShow;
}
//Watch for any changes to the filter text (this is bound to the input in the HTML)
$scope.$watch('gardenModel.externalFilterText', function(value) {
$scope.filterGardens(value);
});
//Watch for any changes on the service (this way if addition/edit are made and
//refresh happens in the service things stay up to date in this view, and the filter stays)
$scope.$watch( function () { return gardenService.gardens; }, function ( gardens ) {
$scope.gardenModel.gardens = gardens;
$scope.filterGardens($scope.gardenModel.externalFilterText);
});
Edit Cleaned up the code formatting a bit and added some comments.

Using custom jQuery radio buttons with CakePHP Form Helper

I'm using a custom jQuery plugin to convert radio buttons to actual images, and it works with basic checkboxes, but when using Cake's built-in input form helper, it acts more as a checkbox by not unchecking the already clicked options. Not only that, but it isn't populating $this->data (or sending anything when the form is submitted).
The js looks like this:
//##############################
// jQuery Custom Radio-buttons and Checkbox; basically it's styling/theming for Checkbox and Radiobutton elements in forms
// By Dharmavirsinh Jhala - dharmavir#gmail.com
// Date of Release: 13th March 10
// Version: 0.8
/*
USAGE:
$(document).ready(function(){
$(":radio").behaveLikeCheckbox();
}
*/
$(document).ready(function() {
$("#bananas").dgStyle();
var elmHeight = "15"; // should be specified based on image size
// Extend JQuery Functionality For Custom Radio Button Functionality
jQuery.fn.extend({
dgStyle: function()
{
// Initialize with initial load time control state
$.each($(this), function(){
var elm = $(this).children().get(0);
elmType = $(elm).attr("type");
$(this).data('type',elmType);
$(this).data('checked',$(elm).attr("checked"));
$(this).dgClear();
});
$(this).mouseup(function() {
$(this).dgHandle();
});
},
dgClear: function()
{
if($(this).data("checked") == true)
{
$(this).addClass("checked");
}
else
{
$(this).removeClass("checked");
}
},
dgHandle: function()
{
var elm = $(this).children().get(0);
if($(this).data("checked") == true)
$(elm).dgUncheck(this);
else
$(elm).dgCheck(this);
if($(this).data('type') == 'radio')
{
$.each($("input[name='"+$(elm).attr("name")+"']"),function()
{
if(elm!=this)
$(this).dgUncheck(-1);
});
}
},
dgCheck: function(div)
{
$(this).attr("checked",true);
$(div).data('checked',true).addClass('checked');
},
dgUncheck: function(div)
{
$(this).attr("checked",false);
if(div != -1)
$(div).data('checked',false).css({
backgroundPosition:"center 0"
});
else
$(this).parent().data("checked",false).removeClass("checked");
}
});
The PHP/Html looks like this:
<span id="bananas-cat" class="cat">
<?= $this->Form->radio('bananas',array(),array('legend' => false, 'id' => 'bananas', 'name' => 'category')); ?>
<label for="bananas">Bananas</label>
</span>
While it upon first inspection may look correct, when clicked, nothing gets passed within $this->data and it acts like a checkbox and doesn't unselect the value when I add an additional radio checkbox.
Although the radio functionality does work without CakePHP's html form helper like so:
<span id="animals-cat" class="cat">
<input type="radio" name="category" id="animals" />
<label for="animals">Animals</label>
</span>
If anyone can help me out here, I would be forever indebted. I've been trying to solve this for way too long now that I'm considering just scrapping the whole idea to begin with.

What I would suggest is see and compare the HTML output of example and one being generated by CakPHP, try to make it similar to example so that you can get your custom-radio-buttons working.
But if you can not do that I would highly recommend to override those helpers by some parameters so that you can get the exact HTML as an output and Javascript should work flawlessly.
Let me know if that does not work for you.
