How to pass multiple input text value to method in controller

I having 3 textbox and I want to send value enter over there to controller method
<input class="form-control" type="text" id="id" name="id">
<input class="form-control" type="text" id="id1" name="id1">
<input class="form-control" type="text" id="id2" name="id2">
#Html.ActionLink("Send", "MethodNameInController", "ColtrollerName", new { id= $('#id').val(),
id1= $('#id1').val(), id2= $('#id2').val()})
and in controller
public ActionResult MethodNameInController(int id, string id1, string id2)
{
//some text here
}
but it's sending null value

If you want to stay on the same view or redirect to another url after, instead of using #Html.ActionLink() try passing the values to the controller using an ajax call.
function submitAjax(){
//purely for readability
var id = $('#id').val();
var id1 = $('#id1').val();
var id2 = $('#id2').val();
//ajax call
$.ajax({
url: "/ControllerName/MethodNameInController",
data: { id: id, id1: id1, id2: id2 },
success: function (result) {
//handle something here
}
});
};
<input class="form-control" type="text" id="id" name="id">
<input class="form-control" type="text" id="id1" name="id1">
<input class="form-control" type="text" id="id2" name="id2">
<button type="button" onclick="submitAjax()">submit</button>
If the method does some processing and then returns you to a different view, you could do a form submit.
function submitForm(){
var $form = $("#idForm");
//optional validation
$form.submit();
};
<form id="idForm" class="form-horizontal" asp-controller="ControllerName" asp-action="MethodNameInController" >
<input class="form-control" type="text" id="id" name="id">
<input class="form-control" type="text" id="id1" name="id1">
<input class="form-control" type="text" id="id2" name="id2">
<!-- type="button" prevents the from from submitting so you can do validation checks in the js -->
<button type="button" onclick="submitForm()">submit</button>
</form>

I got the solution using ajax just want to know is there any direct solution
$(function () {
$('#receipt').unbind('click');
$('#receipt').on('click', function () {
$.ajax({
url: "/Controller/Method",
type: 'POST',
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: JSON.stringify({
fromDate: $("#fromDate").val(),
toDate: $("#toDate").val(),
id: $("#id").val()
}),
async: false
});
});
});

Jquery ajax not working in firefox

My code is working in chrome,safari but its not working in firefox.
Here is my code
<script>
$(document).ready(function () {
$("#loginform").on('submit',(function(e) {
e.preventDefault();
$('#loading').html("Loading....");
$.ajax({
url: "login.php",
type: "POST",
data: new FormData(this),
contentType:false,
cache: false,
processData:false,
async:false,
success: function(data)
{
$('#loading').hide();
$("#message").html(data);
}
});
return false;
}));
});
</script>
Can anyone solve this issue??? I have one more same script in the same page only url is different but its working fine,but this script is not working .Iam getting empty data .But in chrome,safari its working fine.
My Html Code :
<form role="form" method="post" id="loginform" action="">
<div class="form-group">
<label for="username">Username</label>
<input type="text" class="form-control" id="username" name="username" placeholder="Enter Username" required>
</div>
<div class="form-group">
<label for="password"> Password</label>
<input type="password" class="form-control" id="password" name="password" placeholder="Enter password">
</div>
<div class="checkbox">
<label><input type="checkbox" value="" name="user_rememberme" checked>Remember me</label>
</div>
<div id="loading"></div>
<div id="message"></div>
<button type="submit" name="login" class="btn btn-success pull-right">Login</button>
</form>

Never use async:false in ajax call unless you knows specifically wat you are doing.The problem is that async:false freezes the browser until ajax call is complete (either error or success).set it to true or remove it (by default it is true).Implement error block too and check if its an error from server side
success: function(data)
{
$('#loading').hide();
$("#message").html(data);
},error:function(data){
console.log(data)
}

Try this:
<script>
$(document).ready(function () {
$("#loginform").on('submit',(function(e) {
dta = $(this).serialize();
e.preventDefault();
$('#loading').html("Loading....");
$.ajax({
url: "login.php",
type: "POST",
data:dta,
success: function(data)
{
$('#loading').hide();
$("#message").html(data);
}
});
return false;
}));
});
</script>

Inserting Data into MySQL without calling PHP file inside HTML

I have a form:
<form method="post" action="insert.php">
<input type="text" name="firstname" placeholder="Vorname" required>
<br>
<input type="text" name="lastname" placeholder="Nachname" required>
<br>
<input type="text" name="nickname" placeholder="Spitzname" required>
<br>
<input type="email" name="email" placeholder="Email" required>
<br>
<input type="submit" value="Speichern">
</form>
As you can see my action is action="insert.php" so that calls my insert.php. A new url is created and it is opened in the browser.
But what if i dont want that? I want to stay on the same site where the form is and i would prefer not to call any php directly. i would prefer to call a javascript function. For example, my select i do with ajax:
function getData() {
$.ajax({
url: "queries.php",
data: {action: "retrieve_data"},
dataType: "json",
type: "post",
success: function(output) {
// do stuff
}
});
}
Can i also do something like that with the insert?

<html>
<body>
<form method="post" action="insert.php" id="insertForm">
<input type="text" name="firstname" placeholder="Vorname" required>
<br>
<input type="text" name="lastname" placeholder="Nachname" required>
<br>
<input type="text" name="nickname" placeholder="Spitzname" required>
<br>
<input type="email" name="email" placeholder="Email" required>
<br>
<input type="button" id="insertData" value="Speichern">
</form>
<script type="text/javascript" src="lib/js/jquery-2-1-3.min.js"></script>
<script type="text/javascript">
$(function () {
$('#insertData').click({ inputs:$('#insertForm :input') }, getData);
});
function getData(o) {
var values = {};
o.data.inputs.each(function() {
values[this.name] = $(this).val();
});
$.ajax({
url: "queries.php",
data: {action: "retrieve_data", firstname: values['firstname'], lastname: values['lastname'], nickname: values['nickname'], email: values['email']},
dataType: "json",
type: "post",
success: function(output) {
// do stuff
}
});
}
</script>
</body>
</html>
Here you go, you can always edit is as you want, or what values are optional and such.
Remember i've used a type="button" so the page doesn't reload, so the action could just stay empty.

Since you seem to be using jQuery, this is easy; as explained in the documentation. If you give your form id=insertForm this should work:
$("#insertForm").submit(function(e){
$.ajax({
url: "/insert.php",
type: "post",
data: $(this).serialize();
});
e.preventDefault();
});

run php script with ajax shows no result

I'm trying to run a php script using ajax after a form submission.
this is the form
<form id="form" class="form">
<input id="email" type="email" required name="email" placeholder="Email" onchange="myUpdateFunction()" value="">
<textarea id="message" type="text" value="" name="message" onchange="myUpdateFunction()" required placeholder="Comments" style="border:none;border-bottom:1px solid #424242; width:530px;"></textarea>
<input id="submit" type="submit" class="submit" name="send_request" value="Submit" >
</form>
this is my script
$('.submit').on('click', function() {
$.ajax({
url: "send.php",
method:'post',
data: {'email': $('#email').val(), 'message': $('#message').val()}
}).done(function() {
alert('Message Sent.');
});
});
and this is my send.php file
<?php
if(isset($_POST['send_request'])){
//send email
}
?>
but it doens't work, the page is reloaded, the email is not sent and no "alert message" is displayed
there is no problem in php because if I delete the javascript and I add action="send.php" method="POST" as attributes in the form it works, so I think that the problem is the javascript

You shouldn't use the onchange or the click event for this kind of stuff, but the submit event (preventing the default behaviour of submit button).
<form id="form" class="form">
<input id="email" type="email" name="email" placeholder="Email" required>
<textarea id="message" type="text" value="" name="message" placeholder="Comments" required></textarea>
<input id="submit" type="submit" class="submit" name="send_request" value="Submit">
</form>
$("#form").on('submit', function(e) {
e.preventDefault();
$.ajax({
url: "send.php",
method:'post',
data: $( this ).serialize()
}).done(function() {
alert('Message Sent.');
});
});
or (both ways are good)
$(document).ready(function () {
$('#submit').click(function () {
$.ajax({
url: "send.php",
method: 'post',
data: $(this).serialize()
}).done(function () {
alert('Message Sent.');
});
return false;
});
});
Also, about the backend, you should make this kind of check:
if (
isset($_POST["email"]) &&
!empty($_POST["email"]) &&
isset($_POST["message"]) &&
!empty($_POST["message"])) {
//send email
}

Sending values to the action script continuously. How to do that?

I want to repeatedly send values of username and password to the php script. How do I do this ? Like to send the values to the action script, we use submit button but how can I send the values automatically to the script and that too continuously ?
<form method="post" action="processor.php">
<input type="username" value="suhail" />
<input type="password" value="secret_code" />
<input type="submit" />
</form>

Using the jQuery form plugin you can do the following:
setInterval(function() {
$('form').ajaxSubmit();
}, 1000);
Another solution is to target the form to an iframe so if you submit the form, it doesn't reload the page:
HTML:
<form id="myform" method="post" action="processor.php" target="frm">
<input type="username" value="suhail" />
<input type="password" value="secret_code" />
<input type="submit" />
</form>
<iframe name="frm" id="frm"></iframe>
JS:
var form = document.getElementById('myform');
setInterval(function() {
form.submit();
}, 1000);

try something like this
JAVASCRIPT
<script language=javascript>
var int=self.setInterval(function(){send_data()},1000);
function send_data()
{
document.getElementById('my_form').submit()
}
</script>
HTML
<form method="post" id="my_form" action="processor.php">
<input type="username" value="suhail" />
<input type="password" value="secret_code" />
</form>

<form id="myform" method="post" action="processor.php">
<input type="username" value="suhail" />
<input type="password" value="secret_code" />
<input type="submit" />
</form>
<script type="text/javascript">
var count=100,i=0;
for(i=0;i<count;i++) {
document.getElementById('myform').submit();
}
</script>
This will submit the form 100 times

Use Ajax, it's really easy with jQuery. To send the form data to the processor.php script:
var sendForm = function () {
$.ajax({
type: 'post',
url: 'processor.php',
dataType: 'JSON',
data: {
username: $('#username').val(),
password: $('#password').val()
},
success: function (data) {
// do something with the answer from server?
},
error: function (data) {
// handle error
}
});
}
So, sendForm is a function that sends the form data to the server. Now, wee need to set a timer that will invoke it repeatedly:
window.setInterval(sendForm, 1000); // sends form data every 1000 ms

You may you $.post or $.get or $.ajax request repeatedly to send continuous request.
$(document).ready(function(){
setInterval(function() {
var username = $("#username").val();
var password = $("#password").val();
var dataString = 'username='+username+"&password="+password;
$.post('login.php',dataString,function(response){
//your code what you want to do of response
alert(response);
});
}, 1000);
});
and html code is like following
<form method="post" action="processor.php">
<input type="username" value="suhail" id="username"/>
<input type="password" value="secret_code" id="password"/>
<input type="submit" />
</form>

This is a full HTML file doing what you want, read the comments.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<form method="post" action="processor.php">
<input type="username" id="username" value="suhail" />
<input type="password" id="password" value="secret_code" />
<input type="submit" />
</form>
<script>
function send_request(username, password) {
var dataString = 'username='+username+"&password="+password;
$.post('login.php',dataString,function(response){
// You can check if the login is success/fail here
console.log(response);
// Send the request again, this will create an infinity loop
send_request(username, password);
});
}
// Start sending request
send_request($('#username').val(), $('#password').val());
</script>

Try this,
JS:
$(document).ready(function(){
var int=self.setInterval(function(){statuscheck()},1000);
function statuscheck()
{
var username = $("#username").val();
var password = $("#password").val();
$.ajax({
type:"post",
url:"processor.php",
dataType: "html",
cache:false,
data:"&username="+username+"&password="+password,
success:function(response){
alert(response);
}
});
}
});
HTML:
<form method="post" action="processor.php">
<input type="username" value="suhail" id="username"/>
<input type="password" value="secret_code" id="password"/>
<input type="submit" />
</form>
