I have below ajax which I am calling currenlty on form submit. Based on the return result I am showing an alert message only. What I need to do - show a progressbar for some seconds on body load and at the end of the timer call below ajax and based on the return results hide the progressbar and show a success/error msg. How to do this

I am trying to make the change from jQuery to Vue.js and am having some difficulty running an Ajax Call using vueresource. Below is a sample script I am using, with both jQuery and Vuejs. Both trying to access the same ajax call. The jQuery call works, the vuejs call doesn't. The sendAjax method is being called because the first 2 alerts show - then nothing.
Edit - this is only causing an error while running the Ajax call through Wordpress. Outside of WP, it does work. Any ideas??

});
$("#jQueryAjax").click(function() {
alert("jQueryAjax");
alert(JSON.stringify(postData));
alert(AjaxUrl);
$.ajax({
type: 'POST',
url: AjaxUrl,
data: postData,
dataType: 'json',
success: function(data) {
alert(JSON.stringify(data));

error: function (xhr, ajaxOptions, thrownError) {
alert("Error");
}

You AJAX call probably encounters an error and you handle only the successful calls. Please extend your sendAjax function like this:
this.$http.post(AjaxUrl, postData).then(res => {
alert(JSON.stringify(res));
}, err => {
alert(err);
});
Now an error should be alerted.
BTW: It is better to use console.log() instead of alert(), it is much more readable and you won't have to confirm every alert.
After #mbuechmann pointing me to be able to see the actual error, I was able to determine that the issue I was having was actually to do with Wordpress. In order to use the Wordpress Ajax handler, you need to send an action to the REQUEST header. To do this, you need to send FormData, and without sending headers.
This code was found in this question : Custom Shortcode AJAX 400 Bad Request and enabled me to get my Fetch working with Wordpress.
var data = new FormData();
data.append( 'action', 'aj_ajax_demo' ); data.append( 'nonce', aj_ajax_demo.aj_demo_nonce );
fetch(aj_ajax_demo.ajax_url, {
method: 'POST',
body: data, }).then(response => {
if (response.ok) {
response.json().then(response => {
console.log(response);
});
} });
I am trying to submit an AJAX form with Laravel using the code shown below. After I submit the form, all the data is saved in the database as expected apart from the following field which is displayed as NULL in the database.
<textarea name="content" id="editor"></textarea>
<script type="text/javascript">
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$(".btn-submit-add-video").each(function(){
$(this).on("click",function(e){
e.preventDefault();
let form = $(this).closest('form');
$.ajax({
type:'POST',
url: form.attr('action'),
data: form.serialize(),
success:function(data){
alert(data.successful);
}
});
})
});
</script>
public function addVideo(Request $request)
{
$addVideo = new cms_videos;
$addVideo->VideoStatus = $request->VideoStatus;
$addVideo->VideoTitle = $request->VideoTitle;
$addVideo->VideoStrapline = $request->VideoStrapline;
$addVideo->VideoURL = $request->VideoURL;
$addVideo->VideoDescription = $request->content;
$addVideo->VideoTags = $request->VideoTags;
$addVideo->MetaActName = $request->MetaActName;
$addVideo->MetaRegion = $request->MetaRegion;
$addVideo->MetaGenre = $request->MetaGenre;
$addVideo->MetaVenue = $request->MetaVenue;
$addVideo->VideoCoverPhoto = $request->VideoCoverPhoto;
$addVideo->save();
return response()->json(['successful'=>'Video successfully added']);
}
After doing some research I was told to add the following code to the top of the code shown above:
CKEDITOR.instances.SurveyBody.updateElement();
Now all the data is submitted to the database as expected. However when I now submit the form instead of an alert popping up saying "Successful" I am now redirected to the form action URL where it displays "Successful". How can I stop this redirection and display the alert on the page the form was submitted?
I'm not sure but I think the issue is here when you do e.preventDefault() because it works for the button click not for form submission. Try this out and hope it will help you.
Notice: you have to add upload_video class to your forms
<script type="text/javascript">
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
// If the button is type of submit you can remove this part of code
$(".btn-submit-add-video").each(function(){
$(this).on("click",function(e){
e.preventDefault();
let form = $(this).closest('form.upload_video');
form.submit();
})
});
//
$("form.upload_video").on('submit',function(e){
e.preventDefault();
let form = $(this),data=form.serialize();
//
let content=FCKeditorAPI.GetInstance('content').getData();
data['content']=content;
//
$.ajax({
type:'POST',
url: form.attr('action'),
data: data,
success:function(data){
alert(data.successful);
}
});
});
</script>
This part
let content=FCKeditorAPI.GetInstance('content').getData();
May not be true because I don't work with CKEDITOR right now and i can't test it but you can console.log() it before you send the ajax request and make sure the content exists in the variable as you expected.
EDIT
Ok, so I can login fine but when I enter false info I'm redirected to the login page, what I need is to stay on the same page and show the error message e.preventDefault(); doesn't seem to work.
$(function() {
$("#login-form").submit(function(e) {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
error:function(){
$('.fail').show();
e.preventDefault();
},
success: function(){
document.location = '/';
}
});
return false;
});
});
Your not actually doing anything with the form, ill try commenting your code to talk you through whats happening.
I'm guessing your using PHP server side for this code.
In PHP you want to check the user credentials and then tell the browser. If the login was successful send back "y", and if it failed "n".
<script type="text/javascript">
$(function() {
$("#login-form").submit(function() {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
error:function(){
$('.fail').show();
},
success: function(data) {
if (data == "y") {
//Login was successful. Redirect statement here?
} else {
//Failed login message here
}
}
});
return false;
});
});
</script>
Edit
Try adding this in your success function. Please let me know what you get for a successful login and a failed login.
success: function(data) {
console.log(data);
}
Edit 2
This is because your ajax call is successful, just that the login failed. This is why your success handler is called.
To sort this you'll need to see what is being returned from the server, is it nothing? In which case try:
success: function(data) {
if (data == "") {
e.preventDefault();
} else {
//Login successful, redirect user.
}
}
You should add:
success: function(data){
/* Validation data here, if authentication answer is correct */
if(data == 'ok')
document.location = '/';
else
/* show error here */
}
the success occur when URL is found and accessible.
and error occur when URL is not found.
if you want check the callback MSG you must print it in the URL page & check data in success.
like this:
<script type="text/javascript">
$(function() {
$("#login-form").submit(function() {
$('.fail').hide();
$.ajax({
url:"/login",
type: "post",
data: $(this).serialize(),
success:function(data){
if(data=="true"){
alert("success");
}else{
alert("faild")
}
}
});
return false;
});
});
</script>
in login.php
<?php
//check if for true...
echo "true";
//and if it is not true...
echo "false";
?>
the data parameter in success is a string which get back the html content of "/login"
I have the following url in codeigniter.
Add to wishlist
and I have the following jquery function
<script>
$(document).ready(function(){
$('body').on('click', 'a.wishlist_item', function(e){
$.ajax({
url:"../add-item-to-wishlist",
data : "the query string",
success: function(result){
// success code.
}
});
e.preventDefault();
});
});
</script>
how do I get the query string value and pass to the above url ? the add-to-wishlist route redirect to a controller function which take exactly two parameters.
function add_to_wishlist($itemID,$wishlistID = NULL)
What I want to do is call this function using ajax but I dont know how do I call this using ajax
change your anchor URL to the controller method
href = "add_to_wishlist/5/21"
Then you can do a get request with the full URL
<script>
$(document).ready(function(){
$('body').on('click', 'a.wishlist_item', function(e){
e.preventDefault();
var obj = $(this);
$.ajax({
type:'get',
url:obj.attr('href'),
success: function(result){
// success code.
}
});
});
});
</script>
I have made an Ajax function but i am getting a big prolem in that.
I was displaying the contents on click of the link..
The links are fetched from the database and also the url of the links are fetched from the datbase.
I have wriiten ajax to call the contents dynamically on click of the link
<script type="text/javascript">
$(document).ready(function () {
$('a').click(function (e) {
e.preventDefault();
var filename = $(this).text();
var Hobbyurl = '#Url.Action("FetchUrlByHobbyName")';
$.ajax({
type: "POST",
url: Hobbyurl,
data: { data: filename },
success: function (returndata) {
$('iframe').attr('src', returndata);
}
});
});
});
</script>
Now FetchUrlByHobbyName is the function called from the Controller thart returns the url
//Ajax routine to fetch the hobbyinfo by hobbyname
[HttpPost]
public ActionResult FetchUrlByHobbyName(string data)
{
HobbyMasters hobbymaster = new HobbyHomeService().FetchHobbyMasterByHobbyName(data);
string url = hobbymaster.InformationUrl;
if (HttpContext.Request.IsAjaxRequest())
return Json(url);
return View();
}
And in my View i have written the link like this:
#foreach (var item in Model)
{
<li >#Html.ActionLink(item.HobbyName, "Hobbies")
</li>
}
i tried this :
#Html.ActionLink(item.HobbyName, "Hobbies", null, new { id = "alink" })
and then calling Ajax on click of 'alink' but with this my ajax function doesnot get called.
Now the problem is the ajax function is getting called on click of every link on the page..
I want to assign a unique Id to it but i am not understanding how to do that
please Help me...
For that specific link, assign an id. E.g
<a id="someID" href="url">Link</a>
and than bind the click only with that link.
$('#someID').click(function (e)) ....
If I understood you correctly this helps you
The text of the link
<script type="text/javascript">
function myAjaxFunction(){
e.preventDefault();
var filename = $(this).text();
var Hobbyurl = '#Url.Action("FetchUrlByHobbyName")';
$.ajax({
type: "POST",
url: Hobbyurl,
data: { data: filename },
success: function (returndata) {
$('iframe').attr('src', returndata);
}
});
</script>
Try to give a css class selector to you action link like this...
#Html.ActionLink("some link", "Create", "Some_Controller", new { }, new { #class = "test" })
then User jquery for it..
<script type="text/javascript">
$(document).ready(function () {
$('.test').click(function (e) {
e.preventDefault();
var filename = $(this).text();
var Hobbyurl = '#Url.Action("FetchUrlByHobbyName")';
$.ajax({
type: "POST",
url: Hobbyurl,
data: { data: filename },
success: function (returndata) {
$('iframe').attr('src', returndata);
}
});
});
});
</script>
