I have a function for adding likes on the page
blade.php
<a href="/article/{{ $article->id }}?type=heart" class="comments-sub-header__item like-button">
<div class="comments-sub-header__item-icon-count">
{{ $article->like_heart }}
</div>
<a href="/article/{{ $article->id }}?type=finger" class="comments-sub-header__item like-button">
<div class="comments-sub-header__item-icon-count">
{{ $article->like_finger }}
</div>
js
$(function() {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
},
});
$('.like-button').on('click', function(event) {
event.preventDefault();
let href = $(this).attr('href');
$.ajax({
url: href,
type: 'POST',
success: function() {
window.location.reload();
},
});
});
});
But when I click on the like to update the data, I reload the page using window.location.reload();
Can this somehow be done without reloading the page?
This is how adding likes is implemented, they are added to cookies and stored for 24 hours
web routes
Route::post('article/{id}', 'App\Http\Controllers\ArticleController#postLike');
Article controller
public function postLike($id, Request $request) {
$article = Article::find($id);
if(!$article){
return abort(404);
}
$type = $request->input('type');
if ($article->hasLikedToday($type)) {
return response()
->json([
'message' => 'You have already liked the Article '.$article->id.' with '.$type.'.',
]);
}
$cookie = $article->setLikeCookie($type);
$article->increment("like_{$type}");
return response()
->json([
'message' => 'Liked the Article '.$article->id.' with '.$type.'.',
'cookie_json' => $cookie->getValue(),
])
->withCookie($cookie);
}
Article model
public function hasLikedToday(string $type)
{
$articleLikesJson = Cookie::get('article_likes', '{}');
$articleLikes = json_decode($articleLikesJson, true);
if (!array_key_exists($this->id, $articleLikes)) {
return false;
}
if (!array_key_exists($type, $articleLikes[$this->id])) {
return false;
}
$likeDatetime = Carbon::createFromFormat('Y-m-d H:i:s', $articleLikes[$this->id][$type]);
return ! $likeDatetime->addDay()->lt(now());
}
public function setLikeCookie(string $type)
{
$articleLikesJson = Cookie::get('article_likes', '[]');
$articleLikes = json_decode($articleLikesJson, true);
$articleLikes[$this->id][$type] = now()->format('Y-m-d H:i:s');
$articleLikesJson = json_encode($articleLikes);
return cookie()->forever('article_likes', $articleLikesJson);
}
Assuming those DIVs hold the number of hearts, if the response of the target page is the new number of hearts then:
success: function(data) {
targetElement.find(".comments-sub-header__item-icon-count").html(data)
}
elsewhere if you want to add +1 to current number regardless of server response:
success: function() {
var current= parseInt(targetElement.find(".comments-sub-header__item-icon-count").html());
targetElement.find(".comments-sub-header__item-icon-count").html(current+1)
}
Footnote: as the ajax request is nested inside the click function, the targetElement in my codes is the clicked element. You may get it in defferent ways e.g.
$('.like-button').on('click', function(event) {
var targetElement=$(this);
....
}
$(function() {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
},
});
$('.like-button').on('click', function(event) {
event.preventDefault();
let href = $(this).attr('href');
$.ajax({
url: href,
type: 'POST',
success: function(response) {
$(this).parent(".comments-sub-header__item-icon-count").html(
parseInt($(this).parent(".comments-sub-header__item-icon-count").html()) + 1
)
// or return like or heart count from server
$(this).parent(".comments-sub-header__item-icon-count").html(response)
},
});
});
});
This should work for you
$(function () {
$.ajaxSetup({
headers: {
"X-CSRF-TOKEN": $('meta[name="csrf-token"]').attr("content"),
},
});
$(".like-button").on("click", function (event) {
event.preventDefault();
const likeBtn = $(this);
$.ajax({
url: likeBtn.attr("href"),
type: "POST",
success: function () {
let currentCount = likeBtn.next().text();
likeBtn.next().text(parseInt(currentCount) + 1);
},
});
});
});
You can simply add the new count to the response from your controller.
return response()
->json([
'message' => 'Liked the Article '.$article->id.' with '.$type.'.',
'cookie_json' => $cookie->getValue(),
'new_count' => $article->{"like_{$type}"},
])
->withCookie($cookie);
Now you can use the updated count as new_count from the database.
$.ajax({
url: href,
type: 'POST',
success: function (response) {
$(this).next().text(response.new_count)
},
});

Never used ajax before and I'm quite new to Laravel as well.
I'm running a function where it gets the information from the form and i have no idea how to do the request with the information that I need.
function myFunction() {
var x = document.getElementById("frm1");
//console.log(x.elements.personSearch.value);
var details = x.elements.personSearch.value;
document.getElementById("personValidation").innerHTML = "";
if (
!details.match(
/\b[a-zA-Z ]*\\[a-zA-Z ]*\\[0-3][0-9][0-1][0-9][0-9]{4}\b/g
)
) {
document.getElementById("personValidation").innerHTML =
"Your search does not match the required format";
return;
}
$.ajax({
url: "/api/pnc/person",
type: "POST",
dataType: "json",
success:function(amount) {
console.log(amount);
}
});
``` Javascript
public function person(Request $request)
{
$request->validate([
'search' => 'required'
]);
return "test";
}
You need to Follow 3 steps for Ajax Request-
1. Setup Ajax Header bottom of your code. I mean before </html> add below code.
<script>
$.ajaxSetup({
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
</script>
2. If you don't use Header Then you can use.
<script>
$(document).ready(function () {
$("#your_form_id").submit(function(e) {
var details = $('#details_input_id').val();
if(your_condition){
$.ajax({
url: "api/url",
type: "post",
data: {"_token": "{{csrf_token()}}", 'details':details},
success:function(data){
//Your response
if(data){
consol.log("Print what you want to print");
}
}
});
}else{
alert("Your search does not match the required format")
}
});
});
</script>
3. Your Route will be like ajax url
Route::post('api/url', [YourController::class, 'functionName'])->name('functionName');
Currently grecaptcha.execute is being executed on page load as in the first JS example below. If reCAPTCHA challenge is triggered this happens when the page has loaded. Ideally this would happen when the form submit button is clicked instead.
So I've tried this by moving this into the submit event (second JS example) and put the axios function into a promise. It's submitting before grecaptcha.execute has finished executing.
What is it that I'm not understanding here?
My first experience with promises so am I not understanding how promises work? Is that not the best solution for this problem? Is is something else entirely?
HTML
<head>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit" defer></script>
</head>
JS
const form = document.querySelector('#subscribe');
let recaptchaToken;
const recaptchaExecute = (token) => {
recaptchaToken = token;
};
const onloadCallback = () => {
grecaptcha.render('recaptcha', {
'sitekey': 'abcexamplesitekey',
'callback': recaptchaExecute,
'size': 'invisible',
});
grecaptcha.execute();
};
form.addEventListener('submit', (e) => {
e.preventDefault();
const formResponse = document.querySelector('.js-form__error-message');
axios({
method: 'POST',
url: '/actions/newsletter/verifyRecaptcha',
data: qs.stringify({
recaptcha: recaptchaToken,
[window.csrfTokenName]: window.csrfTokenValue,
}),
config: {
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
},
}).then((data) => {
if (data && data.data.success) {
formResponse.innerHTML = '';
form.submit();
} else {
formResponse.innerHTML = 'Form submission failed, please try again';
}
});
}
JS
const onloadCallback = () => {
grecaptcha.render('recaptcha', {
'sitekey': 'abcexamplesitekey',
'callback': recaptchaExecute,
'size': 'invisible',
});
};
form.addEventListener('submit', (e) => {
e.preventDefault();
const formResponse = document.querySelector('.js-form__error-message');
grecaptcha.execute().then(axios({
method: 'POST',
url: '/actions/newsletter/verifyRecaptcha',
data: qs.stringify({
recaptcha: recaptchaToken,
[window.csrfTokenName]: window.csrfTokenValue,
}),
config: {
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
},
})).then((data) => {
if (data && data.data.success) {
formResponse.innerHTML = '';
form.submit();
} else {
formResponse.innerHTML = 'Form submission failed, please try again';
}
});
}
I'm using a web service, as I wanted a method that I could use in all pages.
Special attention to the fact you need to return false; and when the ajax request returns, do your post back.
<script type="text/javascript">
function CheckCaptcha()
{
grecaptcha.ready(function () {
grecaptcha.execute('<%#RecaptchaSiteKey%>', { action: 'homepage' }).then(function (token) {
$.ajax({
type: "POST",
url: "../WebServices/Captcha.asmx/CaptchaVerify",
data: JSON.stringify({ 'captchaToken' : token }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
__doPostBack('<%= RegisterButton.UniqueID%>', '');
//console.log('Passed the token successfully');
},
failure: function (response) {
//alert(response.d);
}
});
});
});
return false;
}
</script>
The way I resolved this is by changing the submit button into a dumb button, and handling everything in a js method:
#Html.HiddenFor(model => model.ReCaptchaToken);
<input type="button"
value="Submit"
onclick="onSubmit()"
/>
Then() method waits for the token, puts it in a hidden field, and only then manually submits the form:
<script>
if (typeof grecaptcha == 'object') { //undefined behind the great firewall
grecaptcha.execute('#Config.ReCaptchaSiteKey', { action: 'register' }).then(function (token) {
window.document.getElementById('ReCaptchaToken').value = token;
$('form').submit();
});
} else {
window.document.getElementById('ReCaptchaToken').value = -1;
$('form').submit();
}
</script>
Note: #Html.HiddenFor is MVC - you might not use that.
$('form') is JQuery - you don't necessarily need that - can use getElementById as well.
I have a link to the Tumblr share widget, and need to append some query string params to it before it opens (triggered by clicking on the link). However, the link opens before these params are appended, I think because it takes a few seconds-- I'm sending an image on the page to be hosted on imgur and returning that URL.
Is there any way to delay the new link from being opened until AFTER my new image url is returned??? I've tried using e.preventDefault(); and return false; but haven't had any luck.
My HTML is:
<button id='tumblrshare'>tumblr</button
$('body').on('click','#tumblrshare',function(e){
var svg = $("#svg")[0];
svg.toDataURL("image/png", {
callback: function(img) {
var img = img.replace("data:image/png;base64,", "");
var imgurTitle = $("meta[property='og:title']").attr("content");
$.ajax({
url: 'https://api.imgur.com/3/image',
headers: {'Authorization': 'Client-ID **********'},
type: 'POST',
data: {'image': img, 'type': 'base64', 'title': imgurTitle},
success: function(result) {
imageURL = result.data.link;
window.location = 'https://www.tumblr.com/widgets/share/tool?canonicalUrl=http://www.example.com&caption=mycaption&posttype=photo&content=' + imageURL;
},
error: function(){
console.log('error');
}
}); //ajax
}//callback
});//svg
}); //tumblrshare
Please help!!
Altering the 'href' attribute of a link won't change it's destination once it's already been clicked. Consider using window.location to redirect the user when your ajax call is complete.
$('body').on('click','#tumblrshare',function(e){
e.preventDefault(); // Stop the default behaviour
...
$.ajax({
success: function(result){
window.location = result.data.link;
},
...
});
...
});
function loadTumblr(){
var svg = $("#svg")[0];
svg.toDataURL("image/png", {
callback: function(img) {
var img = img.replace("data:image/png;base64,", "");
var imgurTitle = $("meta[property='og:title']").attr("content");
$.ajax({
url: 'https://api.imgur.com/3/image',
headers: {'Authorization': 'Client-ID **********'},
type: 'POST',
data: {'image': img, 'type': 'base64', 'title': imgurTitle},
success: function(result) {
imageURL = result.data.link;
window.location.href = 'https://www.tumblr.com/widgets/share/tool?canonicalUrl=http://www.example.com&caption=mycaption&posttype=photo&content=' + imageURL;
},
error: function(){
console.log('error');
}
}); //ajax
}//callback
});//svg
}
$("a.alate").on("click",function(event){

I have similar issue like this one.
I'm trying to make AJAX login using Laravel 5.3 Auth.
Here's what I got so far:
var login = function()
{
var data = {};
data["email"] = $('#email').val();
data["password"] = $('#password').val();
if($('#remember').is(':checked'))
data["remember"] = "on";
$.ajax({
type: "POST",
url: '/login',
data: JSON.stringify(data),
// data: data,
headers : { 'Content-Type': 'application/json' },
success: function(data) {
console.log(data);
// window.location.href = "/dashboard";
}
});
};
I'm sending CRSF token as X-CSRF-TOKEN header.
The problem is that when I successfully login, I say on the same page,
but in Network tab I can see that /dashboard page is loaded by I'm not
redirected.
In the same manner, when I pass wrong credentials, I stay on the same page,
but I can see that /login page is loaded in the separate call with an error message that should be actually displayed.
Also, I've tried without headers : { 'Content-Type': 'application/json' },
and sending data as: data = data, but I get the same thing.
Why the browser doesn't redirect to that page since it is loading it in the "background"?
Edit: I'm getting correct page as request response as well, I can see it
in console (console.log(data);).
//Login FORM
$(document).on('submit', 'form#FormID', function(e) {
e.preventDefault();
var forms = document.querySelector('form#FormID');
var request = new XMLHttpRequest();
var formDatas = new FormData(forms);
request.open('post','/login');
request.send(formDatas);
request.onreadystatechange = function() {
if (request.readyState === 4) {
if (request.status === 200) {
if (request.responseText == 'success') {
setTimeout(function() {
window.location.href = "/dashboard";
}, 5000);
}else{
};
}
}
}
});
//Controller
public function authUser(Request $request){
$data = $request->except('_token');
$validate = \Validator::make($data, [
'email' => 'email'
]);
if ($validate->fails())
return 'Invalid email format for username.';
if (\Auth::attempt($data)) {
return 'success';
}else{
return 'Invalid username or password';
}
}
//Route
Route::post('/login', 'YourController#authUser');
The problem might be with the response AJAX request is expecting before redirect.
Try the above code.
in the controller method
function login(Request $request){
if(\Auth::attempt($request)){
return response()->json('success');
}else{
return response()->json('wrong username or pass', 401);
}
}
in ajax
$.ajax({
type: "POST",
url: '/login',
data: JSON.stringify(data),
// data: data,
headers : { 'Content-Type': 'application/json' },
success: function(data) {
console.log(data);
window.location.href = "/dashboard";
},
error : function(data){
alert(data);
}
});
Here's an interesting solution.
/**
* Get the failed login response instance.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
protected function sendFailedLoginResponse(Request $request)
{
if ($request->ajax()) {
return response()->json([
'error' => Lang::get('auth.failed')
], 401);
}
return redirect()->back()
->withInput($request->only($this->username(), 'remember'))
->withErrors([
$this->username() => Lang::get('auth.failed'),
]);
}
And this:
var loginForm = $("#loginForm");
loginForm.submit(function(e) {
e.preventDefault();
var formData = loginForm.serialize();
$('#form-errors-email').html("");
$('#form-errors-password').html("");
$('#form-login-errors').html("");
$("#email-div").removeClass("has-error");
$("#password-div").removeClass("has-error");
$("#login-errors").removeClass("has-error");
$.ajax({
url: '/login',
type: 'POST',
data: formData,
success: function(data) {
$('#loginModal').modal('hide');
location.reload(true);
},
error: function(data) {
console.log(data.responseText);
var obj = jQuery.parseJSON(data.responseText);
if (obj.email) {
$("#email-div").addClass("has-error");
$('#form-errors-email').html(obj.email);
}
if (obj.password) {
$("#password-div").addClass("has-error");
$('#form-errors-password').html(obj.password);
}
if (obj.error) {
$("#login-errors").addClass("has-error");
$('#form-login-errors').html(obj.error);
}
}
});
});
I have a registration form. After it is submitted, the page refreshes and I get some information back based on request.user. Sometimes request.user.is_authenticated() is returning True and everything works fine.... and sometimes False seemingly randomly.
I appreciate any insight into why this might be happening.
Registration form code
$('#reg_form').submit(function(e) {
e.preventDefault();
e.stopPropagation();
var serializedData = $(this).serializeArray();
var names = serializedData.map(function(r) {
return r.name;
});
var index_user = names.indexOf("regusername");
var index_pass = names.indexOf("regpassword1");
var index_email = names.indexOf("regemail");
var data2 = {};
data2["username"] = serializedData[index_user].value;
data2["password1"] = serializedData[index_pass].value;
data2["password"] = serializedData[index_pass].value;
data2["password2"] = serializedData[index_pass].value;
data2["email"] = serializedData[index_email].value;
console.log(data2);
var serializedFormData = $(this).serialize();
$.ajax({
url: window.url_root + '/accountsjson/register/',
type: 'POST',
dataType: 'json',
data: data2,
success: function(data) {
console.log(data); //remove
if (data.hasOwnProperty('success')) {
console.log("successful registration detected!!");
utils.loginAfterRegister(data2);
$('.register').slideUp();
$('.frame').hide();
} else {
utils.showRegister();
}
},
error: function() {
console.log("ERROR posting registration request. Abort!");
},
});
Function called from loginAfterRegister which has the refresh
function sendRating(rating, reload_on_return) {
$.ajax({
type: "POST",
dataType: 'json',
url: window.url_root + "/savecommentrating/1/" + rating.cid + "/",
data: {
"rating": rating.r2 / 100.0
},
success: function(data) {
if (data.hasOwnProperty('success')) {
console.log("data was sent!");
if (reload_on_return) {
location.reload();
}
}
},
error: function() {
console.log("rating didn't get sent!!");
}
