unable to send data from html div to flask server - javascript

I have a div element with data. I want to pass the div to flask but I'm getting Badrequestkeyerror:400 bad request: keyerror:'yourdiv'
Please find the below html code:

AJAX form submission in Django

I keep receiving 'Not Ajax' as a response during my form submission. I have to be missing something small but I cannot see it...
class VideoLikeView(View):
def post(self, request):
if request.is_ajax():
message = 'Ajax'
else:
message = 'Not Ajax'
return HttpResponse(message)
The AJAX code looks like this:
$(function () {
$("#like-form").submit(function (event) {
$.ajax({
type: "POST",
url: form.attr('action'),
headers: {'X-CSRFToken': '{{ csrf_token }}'},
data: {'pk': $(this).attr('value')},
success: function(response) {
alert('Video liked');
},
error: function(rs, e) {
alert(rs.responseText);
}
}
});
});
});
And my HTML:
<form id="like-form" action="{% url 'video-like' %}" method="post">
{% csrf_token %}
<input name="like"
type="hidden"
value="{{ video.id }}">
<button type="submit">
<span class="video-options ml-auto fas fa-heart fa-2x m-2"></span>
</button>
</form>
One question to add to this; how can I use an <input> in my form without using a <button>? I would like to use fontawesome icons but it seems I have to use a button to get the form to submit.
I found one answer on the internet that seems to work but I don't understand what the issue was. Seems like some type of serialization needed (?)... Anyways, here is what worked:
var frm = $('#like-form');
frm.submit(function () {
$.ajax({
type: frm.attr('method'),
url: frm.attr('action'),
data: frm.serialize(),
success: function (data) {
console.log('success');
},
error: function(data) {
console.log('failed');
}
});
return false;
});
Would love to hear from people why this works and not the previous..
try change your btn type button and add ID for event click :
since putting the submit button goes directly to view.py without going through AJAX
<form id="like-form" action="{% url 'video-like' %}" method="post">
{% csrf_token %}
<input name="like"
type="hidden"
value="{{ video.id }}" id="id_pk">
<button type="button" id="id_btn">
<span class="video-options ml-auto fas fa-heart fa-2x m-2"></span>
</button>
in your script
$("#id_btn").click(function() {
$.ajax({
url:window.location.origin + 'your url'
type: 'POST',
data: {'pk':$(#id_pk).val(), 'accion':'guardar'},
success: function (data) {
console.log('success');
},
error: function(data) {
console.log('failed');
}
});
});
and your view.py
def post(self, request):
if 'guardar' in request.POST['accion']:
print("")

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

Laravel csrf token mismatch on ajax post a second time

im trying to submit an ajax post in laravel but im having some problem regarding the form's csrf token. In my form, if the conditions i set in my ajax post url has been met the first time the form has been submitted. However if i submit the form and purposely failed the conditions i set in my ajax post url in the first try, If i submit the form again i get a token mismatch exception in my ajax error log. Do i need to refresh the csrf_token every ajax post?
Below is my code
JS
$(document).on('submit','.registration-form',function(e){
e.preventDefault();
var form = $(this);
var form_url = $(this).attr("action");
var form_values = $(this).serialize();
$.ajax({
url:form_url,
type:'POST',
data:form_values,
dataType: 'json',
async:false,
success: function(result){
console.log(result);
if(result['status']==true){
location.href = result['redirect'];
}
else{
form.find(".form-details").show().html(result['message']);
}
},
error: function(ts) {
console.log(ts.responseText)
}
});
});
HTML
<form action="{{ url('login') }}" method="POST" class="registration-form">
{{ csrf_field() }}
<input type="text" name="username" class="input" placeholder="Email">
<input type="password" name="password" class="input" placeholder="Password">
<button class="button is-redbox is-flat is-fullwidth">Login</button>
</form>
Are u sure that each time that is send in ajax?
data: {
"_token": "{{ csrf_token() }}",
}
$("#cform")[0].reset();
or in plain javascript:
document.getElementById("cform").reset();
public function regenerateToken(){
session()->regenerate();
return response()->json([
'msg'=>'success',
'token'=>csrf_token()
]);
}
$('#form').submit(funtion(event) {
event.preventDefault(event);
// Submit the form using AJAX.
$.ajax({
type: 'POST',
url: form.attr('action'),
data: formData
})
.done(function(response) {
// Make sure that the formMessages div has the 'success' class.
if (response.msg === 'success') {
$('#token').val(response.token);
console.log($('#token').val());
}
}
$('input[type="text"],input[type="email"] ,textarea, select').val(''); $(this).trigger('reset');
});

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;
});
});

post html form in json format using ajax to Django

I have the below html form, which I would like to post to a url using ajax in JSON format,
I am unable to receive the response in Django (backend), please advise where I am going wrong.
Here is my html form.
<form id ="addressform" >
<input type="text" name="DoorNo" id="text-basic" value="" placeholder="Door no.">
<input type="text" name="BuildingName" id="text-basic" value="" placeholder="Building/Road Name">
<button type="submit" onclick="addressform()" >Submit</button>
</form>
Here is my jQuery
function addressform() {
var data = $('#addressform').serializeArray();
$.post('/suggestions', data);
}
Here is my function in views.py in Django (backend).
def suggestions(request):
data = json.loads(request.body)
#print data
return HttpResponse( json.dumps({"status" : 1}) )
Can you add the URL above that you direct to?
function addressform() {
$.ajax({
url : "{% url 'app:your_view' %}",
type: "POST",
data: { ... },
success : function(json) {
//success!
console.log(json);
},
error : function(xhr,errmsg,err) {
// what to do it there is an error
}
});
};
})
Also depending on the version of python you are using. You could use
return JsonResponse(data_you_want)
I'm a little confused as to what you're doing in your view...
