jquery ajax form submit with edit values

I have a datatable where I have the detail column with an edit button. When the user clicks on the edit am passing the id as a parameter. I am fetching all the values for that id and displaying in the form. Now when I edit the values and submit the form using PUT method it is getting inserted in the table, the values are passing as a parameter and it shows the empty form. How to solve this issue.
HTML:
<form class="container" id="myform" name="myform" novalidate>
<div class="form-group row">
<label for="position" class="col-sm-2 col-form-label fw-6">Position</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="position" name="position" placeholder="Position" required>
</div>
</div>
<div class="form-group row">
<label for="location" class="col-sm-2 col-form-label fw-6">Location</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="location" name="location" placeholder="Location" required>
</div>
</div>
<div class="form-group row">
<div class="col-sm-10">
<button type="submit" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
PUT Method Script:
<script type='text/javascript'>
$(document).ready(function(){
$("#myform").submit(function(e) {
var parms = {
position : $("#position").val(),
location : $("#location").val()
};
var par_val;
var param_id = new window.URLSearchParams(window.location.search);
par_val = param_id.get('id');
console.log(par_val);
var par_url = par_val;
$.ajax({
url: "http://localhost:3000/joblists/"+par_val,
method: 'PUT',
async: false,
dataType : "json",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(parms),
success: function(data){
console.log('Submission was successful.');
console.log(data);
},
error: function (data) {
console.log('An error occurred.');
console.log(data);
},
})
});
});
</script>
GET method script:
<script type="text/javascript">
$(document).ready(function(){
var id_val;
var params = new window.URLSearchParams(window.location.search);
id_val = params.get('id');
console.log(id_val);
var url1=id_val;
$.ajax({
url: "http://localhost:3000/joblists/"+id_val,
type: "GET",
dataType: "json",
success: function (data) {
// alert(JSON.stringify(data));
console.log(typeof(data));
$("#position").val(data.position);
$("#location").val(data.location);
},
error: function(data) {
console.log(data);
}
});
});
</script>
After submitting the form the page should remain the same with edit form values. only the edited values should be inserted. How to achieve this.

$('#myform').on('submit', function (e) {
e.preventDefault();
..........

I have checked your code in my editor. There are some changes which i made in ajax request, and it now works for me. here is the code. Try it
<script type='text/javascript'>
$(document).ready(function(){
$("#myform").submit(function(e) {
e.preventDefault();
var parms = {
position : $("#position").val(),
location : $("#location").val()
};
var par_val;
var param_id = new window.URLSearchParams(window.location.search);
par_val = param_id.get('id');
console.log(par_val);
var par_url = par_val;
$.ajax({
url: "http://localhost:3000/joblists/"+id_val,
method: 'POST', //or you can use GET
dataType : "json", //REMOVED CONTENT TYPE AND ASYNC
data: {send_obj:JSON.stringify(parms)}, //ADDED OBJECT FOR DATA
success: function(data){
console.log('Submission was successful.');
console.log(data);
},
error: function (data) {
console.log('An error occurred.');
console.log(data);
},
})
});
});
</script>

Adding prevent default in form submit handle is enough. You're handling the post request by ajax call.
e.preventDefault();

There are 2 changes in your code.
This code will prevent your page from reloading and also you are not sending the data in proper format.
$("#myform").submit(function(e) {
e.preventDefault(); // 1. Dont reload the page
var parms = {
position : $("#position").val(),
location : $("#location").val()
};
var par_val;
var param_id = new window.URLSearchParams(window.location.search);
par_val = param_id.get('id');
console.log(par_val);
var par_url = par_val;
$.ajax({
url: "http://localhost:3000/joblists/"+par_val,
method: 'PUT',
async: false,
dataType : "json",
contentType: "application/json; charset=utf-8",
data: parms, // 2. Just send the parms object bcoz you already defined the dataType as json so it will automatically convert it into string.
success: function(data){
console.log('Submission was successful.');
console.log(data);
},
error: function (data) {
console.log('An error occurred.');
console.log(data);
},
})
});

Form submission using AJAX in Laravel 5.5

I am trying to submit a form using ajax in Laravel 5.5
The problem is the page is refreshing and not submitting data in the database. I need to store data in the database without refreshing the page.
Here is my code:
Controller
public function new_timing_table(Request $request)
{
if (Request::ajax()) {
$timing_tables = new Timing_Table;
$timing_tables->timing_tables_name = $request->timing_tables_name;
$timing_tables->save();
$msg = "yes";
} else {
$msg = "yes";
}
return ['msg'=> $msg];
}
View
<form id="timeForm" class="form-horizontal form-material" >
<div class="form-group">
{{ csrf_field() }}
<div class="col-md-12 m-b-20">
<label> Table Name</label>
<input type="text" id="timing_tables_name" class="form-control"
name="timing_tables_name" />
</div>
<div class="modal-footer">
<input type="button" value="Replace Message" id='btnSelector'>
</div>
</div>
</form>
Ajax script
const xCsrfToken = "{{ csrf_token() }}";
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': xCsrfToken
}
});
jQuery(document).ready(function() {
jQuery('#btnSelector').click(function(e) {
event.preventDefault();
getMessage();
});
});
var getMessage = function() {
var timing_tables_name = $("input[name=timing_tables_name]").val();
$.ajax({
type: 'post',
url: '/new_timing_table',
dataType: 'json', //Make sure your returning data type dffine as json
data: timing_tables_name,
//data:'_token = <php echo csrf_token() ?>',
success: function(data) {
console.log(data); //Please share cosnole data
if (data.msg) //Check the data.msg isset?
{
$("#msg").html(data.msg);
}
}
});
}
Router
Route::post('/new_timing_table','Timing_TableControoler#new_timing_table');

You got a typo or a mistake in your script.
jQuery('#btnSelector').click(function(e){
// An error here - it should be e.preventDefault();
event.preventDefault();
getMessage();
});

My code is working now after adding beforeSend: function (request) in Ajax script
var getMessage = function(){
var timing_tables_name = $("#timing_tables_name").val();
console.log(timing_tables_name);
$.ajax({
type:'GET',
url:'/new_timing_table', //Make sure your URL is correct
dataType: 'json', //Make sure your returning data type dffine as json
data:
{
timing_tables_name
},
beforeSend: function (request) {
return request.setRequestHeader('X-CSRF-Token', $("meta[name='csrf-
token']").attr('content'));
},
success:function(data){
console.log(data); //Please share cosnole data
if(data.msg) //Check the data.msg isset?
{
$("#msg").html(data.msg); //replace html by data.msg
}
}
});
}
and editing the controller to be simple as this one
public function new_timing_table(Request $request){
$timing_tables = new Timing_Table;
$timing_tables->timing_tables_name = $request->timing_tables_name;
$timing_tables->save();
$msg = "This is a simple message.";
return ['msg'=> $msg];
}
Thank you all for your help

Image is not inserted with data using ajax jquery in asp.net MVC

I'm trying to insert data to database using ajax with Jquery. My data is inserted without ajax perfectly but when i use ajax, there is something wrong with image. it get the file null in the controller in post method.
This is my Form in the View.
<form id="InsertForm" name="InsertForm" enctype="multipart/form-data">
<div class="form-group">
<label for="Name">Name</label>
<input type="text" class="form-control" name="StudentName" id="name" />
</div>
<div class="form-group">
<label for="LastName">Last Name</label>
<input type="text" class="form-control" name="StudentLastName" id="last" />
</div>
<div class="form-group">
<label for="Address">Address</label>
<input type="text" class="form-control" name="StudentAddress" id="address" />
</div>
<div class="form-group">
<label for="Gender">Gender</label>
<input type="text" class="form-control" name="Gender" id="gender" />
</div>
<div class="form-group">
<label for="Image">Image</label>
<input type="file" class="form-control" id="StudentImage" name="StudentImage" />
</div>
<button id="saveclick" type="submit" name="save">Save</button>
</form>
This is my Script in the View for inserting data with image.
<script>
$(document).ready(function () {
$("#saveclick").click(function (e) {
var student = {
StudentName: $("#name").val(),
StudentLastName: $("#last").val(),
StudentAddress: $("#address").val(),
Gender: $("#gender").val(),
StudentImage: $("#StudentImage").val().split('\\').pop()
};
//var formdata = new FormData($('InsertForm').get(0));
//var Student= $("#InsertForm").serialize();
var jsonData = JSON.stringify(student);
alert(jsonData);
$.ajax({
type: "POST",
url: '#Url.Action("Insert", "Student", null)',// Insert Action Method in Student Controller.
contentType: "application/json; charset=utf-8",
dataType: "json",
enctype: 'multipart/form-data',
data: jsonData,
success: function (data) {
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
return false;
});
});
</script>
This is my Controller action Method in Student Controller.
[HttpPost]
public JsonResult Insert(Student student)
{
if (ModelState.IsValid)
{
Student stu = new Student();
stu.StudentName = student.StudentName;
stu.StudentLastName = student.StudentLastName;
stu.StudentAddress = student.StudentAddress;
stu.Gender = student.Gender;
HttpPostedFileBase file = Request.Files["StudentImage"];
file.SaveAs(HttpContext.Server.MapPath("~/Images/") + file.FileName);
stu.StudentImage = file.FileName;
db.Students.Add(stu);
db.SaveChanges();
return Json(student);
}
else
{
ModelState.AddModelError("", "Inavlid Data Inserted");
}
return Json(student);
}
Thanks if you solve my this problem.

try following
<script type="text/javascript">
$(document).ready(function () {
$("#saveclick").click(function (e) {
var data = new FormData();
var files = fileUpload.files;
fileData.append("StudentImage", files[0]);
fileData.append("StudentName",$("#name").val());
/* add all values as above one by one for LastName,Gender,Address*/
$.ajax({
type: "POST",
url: '#Url.Action("Insert", "Student", null)',// Insert Action Method in Student Controller.
contentType: "application/json; charset=utf-8",
processdata: false,
data: data,
type:"POST"
success: function (data) {
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
return false;
});
});
</script>

Here is the solution that solve my great problem. We need to append the ForamData in any variable.
<script>
$(document).ready(function () {
$("#saveclick").click(function (e) {
// Create FormData object
var fileData = new FormData();
var fileUpload = $("#StudentImage").get(0);
var files = fileUpload.files;
// Looping over all files and add it to FormData object
//for (var i = 0; i < files.length; i++) {
// fileData.append(files[i].name, files[i]);
//}
fileData.append("StudentImage", files[0]);
fileData.append("StudentName", $("#name").val());
fileData.append("StudentLastName", $("#last").val());
fileData.append("StudentAddress", $("#address").val());
fileData.append("Gender", $("#gender").val());
$.ajax({
type: "POST",
url: '#Url.Action("Insert", "Student", null)',
data: fileData,
processData: false,
contentType: false,
success: function (data) {
if (data.success) {
alert(data.message);
}
},
error: function (xhr) {
alert('error');
}
});
return false;
});
});
</script>

AJAX call display response from php script in html

I have a html file where users can input a value.
I wrote a script in PHP that checks if this value is present in the databse. If it's present it returns
{"active":true}
Now my goals is that when the user inputs their value and submit they will be redirected to a certain page if this active is true. If it's false they should see an error message.
So here's what I've tried with my AJAX call:
$("document").ready(function(){
$(".checkform").submit(function(e){
e.preventDefault();
$.ajax({
type: "GET",
dataType: "json",
url: "api/check.php",
data: data,
success: function(data) {
if(data.active=="true"){
alert("success");
location.href="where_you_want";
}else{
alert("failure");
}
}
});
return false;
});
});
Here is my HTML:
<form action="api/check.php" id="requestacallform" method="GET" name="requestacallform" class="formcheck">
<div class="form-group">
<div class="input-group">
<input id="#" type="text" class="form-control" placeholder="Jouw subdomein" name="name"/>
</div>
</div>
<input type="submit" value="Aanmelden" class="btn btn-blue" />
</form>
For some reason I get an error:
Uncaught ReferenceError: data is not defined
I am new to AJAX and I am not sure if what I am trying is correct.
Any help would be greatly appreciated!
Thanks in advance.

Can you try:
$(".aanmeldenmodal").submit(function(e){
e.preventDefault();

I am updating my answer in whole
<html>
<body>
<form action="api/check.php" id="requestacallform" method="GET" name="requestacallform" class="formcheck">
<div class="form-group">
<div class="input-group">
<input id="txt1" type="text" class="form-control" placeholder="Jouw subdomein" name="name"/>
</div>
</div>
<input type="submit" value="Aanmelden" class="btn btn-blue checkform" />
</form>
</body>
</html>
jQuery part is like
$("document").ready(function () {
$("body").on("click", ".checkform", function (e) {
e.preventDefault();
var request = $("#txt1").value;
$.ajax({
type: 'GET',
url: 'ajax.php',
data: {request: 'request'},
dataType: 'json',
success: function (data) {
if(data.active==true){
alert("success");
}else{
alert("failure");
}
}
});
});
});
ajax.php should be like this
if(isset($_GET['request'])){
//check for the text
echo json_encode($arr);
}

In api/check.php
You can pass data in json format
$json = json_encode($data);
retrun $json;
You can also not share any data so You can remove data from jQuery.
data:data
Your Jquery look like this:
$("document").ready(function(){
$(".checkform").submit(function(e){
e.preventDefault();
$.ajax({
type: "GET",
dataType: "json",
url: "api/check.php",
success: function(data) {
if(data.active=="true"){
alert("success");
location.href="where_you_want";
}else{
alert("failure");
}
}
});
return false;
});
});

I am having undefine index : images

Go through this code, it may help
var data = new FormData();
data.append("Avatar", file.files[0]);
$.ajax({
url: "http://192.168.1.1:2002/,
type: "POST",
data:data,
contentType: false,
cache: false,
processData:false,
success: function(data)
{
console.log(data);
}
});

Its posible that the file is not upload becouse of some error. You should review the parameters related to file upload as UPLOAD_MAX_SIZE, etc.
You can use var_dump($file) to see the $_FILE content.

You need to be sending your data through FormData().
Try something like this:
var images = $("#images").get(0).files;
var formData = new FormData();
$.each(images, function(i, image) {
data.append("images[]", image);
});
Then send formData as your $.ajax data.
