How to submit a value by clicking on a div?

I'm working on Asp.net Mvc news website like (yahoo, BBC ...).
I have loads of divs that contains the feed title,text and image.What I want to achieve is to make these divs that contains these 3 elements clickable no matter where I clicked (title,text or feed image)and to post the value of the feed ID to my controller method.
I've done this already like this:
In my feed table I have : FeedID-FeedText-FeedPath
View:
#foreach (Feeds item in Model.FeedViewModel)
{
<div class="col-4">
#using (Html.BeginForm("goToFeed", "Home"))
{
<h3>#item.title</h3>>
<button type ="submit" name="FeedID" value="#item.FeedID"
style="background:none; border:none" href="#">#item.FeedText</button>
<img src="#Url.Content(#item.FeedPath)">
}
</div>
}
And in my controller I'm taking the "FeedID"
Controller:
[HttpPost]
public ActionResult goToFeed(int FeedID)
{
//some code here
}
I guess there should be a way to post the FeedID inside this div without making it a button.
I've checked these posts already but none of them helped me.
Form submit by click on a div element without JS
submiting form on div click with js
Thanks for any help...

You should not use a POST request to read data. The correct HTTP verb in this case would be GET. POST should mainly be used to create new entries. See Using HTTP Methods for RESTful Services.
This has not only academic reasons. If you use POST, and your users use the backwards/forwards buttons of the browser to navigate, they would see "Are you sure you want to resubmit the form?" messages.
To use GET, your CSHTML could look like this. Use CSS marker classes js-feed and js-feedId so you can later access these elements using jQuery.
#foreach (Feeds item in Model.FeedViewModel) {
<div class="col-4 js-feed">
<h3>#item.title</h3>>
<span>#item.FeedText</span>
#Html.HiddenFor(m => item.FeedID, new { #class = "js-feedId" })
</div>
}
The URL to the GET action is configured in the JS part. Extract the FeedId from the clicked div, replace the placeholder in the configured URL with this FeedId, and then redirect to this action by setting window.location.href, which will reload the page.
If you do not want to reload the entire page, use $.ajax instead.
<script type="text/javascript">
$(document).ready(function() {
var getUrl = '#Url.Action("goToFeed", "Home", new { FeedID = "To_Be_Replaced_By_JS" })';
$('.js-feed').on('click', function() {
var feedId = $('.js-feedId', $(this)).val(); // search only inside clicked element
var feedUrl = getUrl.replace('To_Be_Replaced_By_JS', feedId);
window.location.href = feedUrl;
});
});
</script>
The target controller action should be attributed with [HttpGet].
[HttpGet]
public ActionResult goToFeed(int FeedID) {
//some code here
}

Change this:
#foreach (Feeds item in Model.FeedViewModel)
{
<div class="col-4">
#using (Html.BeginForm("goToFeed", "Home"))
{
<h3>#item.title</h3>>
<button type ="submit" name="FeedID" value="#item.FeedID"
style="background:none; border:none" href="#">#item.FeedText</button>
<img src="#Url.Content(#item.FeedPath)">
}
</div>
}
To this:
#foreach (Feeds item in Model.FeedViewModel)
{
<div class="feed col-4">
#using (Html.BeginForm("goToFeed", "Home"))
{
#Html.HiddenFor(m => item.FeedID)
<h3>#item.title</h3>>
<button type ="submit" name="FeedID" value="#item.FeedID"
style="background:none; border:none" href="#">#item.FeedText</button>
<img src="#Url.Content(#item.FeedPath)">
}
</div>
}
Then add this to your page:
<script
src="https://code.jquery.com/jquery-3.3.1.min.js"
integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
crossorigin="anonymous"></script>
<script type="text/javascript">
$(function() {
$('.feed').click(function() {
return $(this).closest("form").submit();
});
});
</script>

Having a field is required when posting a razor form to the server so having the FieldID hidden will allow this to be sent. Having a div surrounding the area adding the onclick attribute with a submit function to post the above form document.forms[0].submit() can also be used.
#foreach (Feeds item in Model.FeedViewModel)
{
<div class="col-4">
#using (Html.BeginForm("goToFeed", "Home"))
{
<div onclick="this.parentNode.submit()">
#Html.HiddenFor(m => item.FeedID)
<h3>#item.title</h3>>
<button type ="submit" name="FeedID" value="#item.FeedID"
style="background:none; border:none" href="#">#item.FeedText</button>
<img src="#Url.Content(#item.FeedPath)">
</div>
}
</div>
}

Javascript issue in Laravel 5

I'm learning laravel 5 about one month, and now i having a problem with javascript.
I add an form click on blade file to delete the post.
But now i don't want to use form, i replace that by javascript.
How can i detect when use touch the delete'button.
#extends ('layouts.master')
#section ('head.title')
Blog
#stop
#section ('body.content')
<div class="container">
<div class="row">
<div class="col-sm-6 col-sm-offset-3">
</div>
</div>
<form class="form-show">
<div class="row">
<div class="col-sm-6 col-sm-offset-3">
<h2> {{ $article->title}} </h2>
<p> {{ $article->content}} </p>
</div>
<div class="row">
<div class="col-sm-6 col-sm-offset-3">
Cập nhật
<button type="submit" class="btn btn-primary">Xoa</button>
</div>
</div>
</div>
</form>
</div>
<script src="jshow.js"></script>
#stop

Add id to button so it is easily locatable in Javascript
<button id="delete-button" type="submit" class="btn btn-primary">Xoa</button>
Next add this javascript
var deleteButton = document.getElementById("delete-button");
deleteButton.onclick = function() { delete(); return false; }
Process the deleting in delete() method

Try this :
<!DOCTYPE html>
<html>
<body>
<button onclick="myFun()">Click me</button>
<p id="demo"></p>
<script>
function myFun() {
console.log('Clicked');
}
</script>

Since HTML forms can't make PUT, PATCH, or DELETE requests, you will need to add a hidden _method field to spoof these HTTP verbs
Also, don't forget to add csrf-token as well which is needed in order to validate a POST request.
First add this meta tag inside your <head>.
<meta name="csrf-token" content="{{ csrf_token() }}">
Then place this code at the top of your JS file.
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
Now, you can make use of data-* attribute to hold the route of that article for AJAX.
<button data-route="{{ route('article.destroy', $article->id) }}" class="btn btn-danger deleteArticle">Delete</button>
In your JS
document.querySelector('.deleteArticle').addEventListener('click', function() {
var route = this.dataset.route;
if (confirm("Are you sure you wish to delete this article?")) {
$.ajax({
method: 'POST',
url: route,
data: {
"_method": 'DELETE',
},
success: function() {
// handle success here
},
error: function() {
// handle error here
},
});
}
});

Redirecting to specific slug from textfield in ember

I am totally new to ember so please be nice :)
I have an Ember app where i want to redirect to a specific slug taken from an textfield input. In my .hbs i have the following code:
<div class="liquid-container">
<div class="liquid-child">
<div class="desktop-layout-scroll-container">
<div class="overlay-info-layout">
<div class="overlay-info-layout-content">
<h1 class="expired-overlay-status">{{t 'code.title'}}</h1>
<h2 class="expired-overlay-explanation">
{{t 'code.description'}}<br>
</h2>
<div class="row">
<div class="col-xs-offset-3 col-xs-6">
<input name="txtSlug" type="text" id="txtSlug" class="field" />
<input type="submit" name="btnGo" value="" id="btnGo" class="btn" onclick="javascript:SubmitForm()" />
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<script type="text/javascript">
function SubmitForm(){
var Slugtxt = document.getElementById("txtSlug").value;
window.location = "http://www.google.com/" + Slugtxt;
}
</script>

You should never embed JavaScript in an Ember .hbs file. This code should really go in your controller for this class. First, generate your controller:
ember g controller <name_of_route>
Then inside your controller, you want to define two things. The slugtxt variable, and the redirecting as an action. That would look something like this:
import Ember from 'ember';
export default Ember.Controller.extend({
slugtxt: '',
actions: {
redirect() {
window.location = "http://www.google.com/" + this.get('slugtxt');
}
}
}
Then, back in your template, you would want to change your input to be mapped to the slugtxt variable from your controller, and set the action of the button to the redirect action that you defined in your controller. That would look something like this:
{{input value=slugtxt}}
<button {{action "redirect"}}>Submit</button>
No need to worry about using the <input> tag, you generally wont be using form data with ember.

Get the HTML Class Name inside Partial View in JavaScript or jQuery

I have the following markup inside my .cshtml Partial View and it is placed in the Views/Shared folder:
_Modal.cshtml
<div class="loadingOverlay">
<button class="btn loading-button" disabled><i class="fa fa-spinner fa-pulse fa-2x fa-fw"></i></button>
</div>
And also the External JavaScript (different file from the Partial View .cshtml):
Modal.js
var Modal;
Modal = Modal || (function () {
var loadingDiv = $('.loadingOverlay');
return {
Loading: function () {
loadingDiv.css('display', 'block');
$('body').prepend(loadingDiv);
},
LoadingDismiss: function () {
loadingDiv.fadeOut('500');
},
};
})();
And I call from my page like below:
Index.cshtml
<!DOCTYPE html>
<html>
<head>
#Styles.Render("~/Content/font-awesome", "~/Content/css")
</head>
<body>
<div class="container-fluid">
<div class="container">
<div class="row">
<button id="showOverlay" class="btn btn-default"></button>
</div>
</div>
</div>
#Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
$(document).ready(function () {
$('#showOverlay').click(function () {
Modal.Loading();
});
})
</script>
</body>
</html>
My problem is: whenever I clicked the button, nothing happens. But it works when I put the html element not inside _Modal.cshtml (Refer to the below code).
My question is: how can I get the class name in the _Modal.cshtml using JavaScript or JQuery?
I can do this in the Modal.js (Note that it is same as I put that into _Modal.cshtml) but that would be hard to maintain and I would like to put all of the content in the Partial View, and call it when needed by class name, instead of write string that will converted to JavaScript Object:
var loadingDiv = $('<div class="loadingOverlay"><button class="btn loading-button" disabled>'
+ '<i class="fa fa-spinner fa-pulse fa-2x fa-fw"></i></button></div>');
Your answer much appreciated.
Edit:
Question on 31st of May 2016:
What's the difference between #Html.Partial("_Modal") with #Html.Partial("~/Views/Shared/_Modal.cshtml"). is it just to better understand for where the compiler get the partial views from?
Answered on 1st of June 2016 by #Guruprasad Rao:
There is nothing difference between two except the mentioning of partialview name. The one I suggested was providing fully qualified path which helps compiler from where to fetch the partialview. To one you use will search in all the directories under the View folder. So the one I mentioned will be good in the aspect of performance.
Thanks for the #Guruprasad Rao for the answer and the explanation.
Cheers~

You should import the partialview first from server to client browser first and then you can manipulate it with jquery. Otherwise there would be no element with the selector you are trying to find. User, #Html.Partial or #Html.RenderPartial to import it, hide it at initial state and show it on click. Take a below example:
<body>
<div class="container-fluid">
<div class="container">
<div class="row">
<button id="showOverlay" class="btn btn-default"></button>
</div>
</div>
</div>
#Html.Partial("~/Views/Shared/_Modal.cshtml")
<!--I assume that the content inside this will be initially in hidden state-->
#Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
$(document).ready(function() {
$('#showOverlay').click(function() {
Modal.Loading();
});
})
</script>
</body>
Modal.js changes
var Modal;
Modal = Modal || (function () {
var loadingDiv = $('.loadingOverlay');
return {
Loading: function () {
loadingDiv.css('display', 'block');
//$('body').prepend(loadingDiv);
//No need to prepend here since we are importing it through partial method
},
LoadingDismiss: function () {
loadingDiv.fadeOut('500');
},
};
})();

load js file to view in ci bonfire

I have a Module call ftp_data. Also I have a js file inside my Module Assets folder bonfire/modules/ftp_data/assets/js/ftp_data.js.
Now I want to load this file to my view
Inside View
<!-- Edit by Yesh -->
<div class="container-fluid">
<form method="POST" id="url_finder" name="url_finder">
<div class="span4">
<h3>Search URL : <input type="search" id="search_url" name="search_url" placeholder="www.example.com"></h3>
</div>
<div class="span3">
<button id="url_btn" name="url_btn" class="btn" type="submit">Search</button>
</div>
</form>
</div>
<!-- Edit by Yesh -->
inside ftp_data.js
$(function(){
$('#search_url').keyup(function(){
var s = new RegExp(this.value.toLowerCase());
$('.result_table .result_row').each(function() {
if(s.test(this.innerHTML.toLowerCase())){
$(this).show();
}else{
$(this).hide();
}
});
});
});

To load js/css file in you View module you should use constructor method. You can simply copy my code i have added below.
code like :
public function __construct()
{
parent::__construct();
Assets::add_module_js('ftp_data', 'ftp_data.js');
}
add_module_js() : first parameter defines the name of the module to be use and second parameter define the files to be load.

Put this code on your view file
<script src="assets/js/ftp_data.js"></script>

Finally I found the solution. This is what I found. I hope it will help you too.
public function index()
{
//---functions will goes here
//--Add this code before closing public function index
Assets::add_module_js('ftp_data', 'ftp_data.js');
//--ftp_data is the Module name.
//--ftp_data.js is the name of the js file that is inside the module/assets/js/
}
