i have ajax code below
$.ajax({
type: "POST",
url: "shoppingcart_service.asmx/RegisterSubscriber",
data: "email=" + SubscriberEmail, // the data in form-encoded format, ie as it would appear on a querystring
//contentType: "application/x-www-form-urlencoded; charset=UTF-8", // if you are using form encoding, this is default so you don't need to supply it
dataType: "text", // the data type we want back, so text. The data will come wrapped in xml
success: function (data) {
$("#searchresultsA").html(data); // show the string that was returned, this will be the data inside the xml wrapper
},
error: function (request, status, error) {
}
});
}
how do i add an onbegin function to begin spining the button that calls this function, and end it using onend ajax function,
i am using font-awesome as gylphicon (http://fontawesome.info/website-lists-and-examples-using-font-awesome-icon-css/fa-arrow-circle-right), and i need to show the rotating
<i class="fa fa-arrow-circle-right fa-2x fa-spin"></i> when call begins, there by replacing
<i class="fa fa-arrow-circle-right"></i>
here is the buttons' html
</i></i>Subscribe
Example uses the jQuery JavaScript library.
First, create an Ajax icon using the AjaxLoad site.
Then add the following to your HTML:
<img src="/images/loading.gif" id="loading-indicator" style="display:none" />
And the following to your CSS file:
#loading-indicator {
position: absolute;
left: 10px;
top: 10px;
}
Lastly, you need to hook into the Ajax events that jQuery provides; one event handler for when the Ajax request begins, and one for when it ends:
$(document).ajaxSend(function(event, request, settings) {
$('#loading-indicator').show();
});
$(document).ajaxComplete(function(event, request, settings) {
$('#loading-indicator').hide();
});
Taken from source.
One Liner
<i class="fa fa-refresh fa-spin"></i>
More of it here.
Use the following as in FA docs
<i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>

I have a form with an input of type file hidden. An image tag works as the clickable trigger to select the file itself, with js to trigger it (that works), but I want to automatically make a PUT request as one chooses an image instead of having to click a submit button on the form, every time the image is changed on the input field. I'm using ajax for that, but at the controller endpoint that processes the request, I don't seem to have any file. If I put other fields such as textual they seem to pass into the controller through the request just fine, though.
My route:
Route::put('/coins/image/{key}', [CoinController::class, 'image'])->name("coins.image");
My controller (no actual image-updating code yet; just what I'm doing to check for the file):
public function image(int $key)
{
dump(request()->file('file'));
dump(request()->file);
dump(request());
}
My HTML and JS in the following snippet:
function promptImageForUpload(elemId)
{
$('#' + elemId).click();
}
function uploadImage(event, imgId, key)
{
event.preventDefault();
var inputElem = event.target;
var imageFile = inputElem.files[0];
var imgElem = $('#' + imgId);
var form = $(inputElem).parent();
var formData = new FormData(form[0]);
formData.append('file', imageFile);
$.ajax({
url: "/coins/image/" + key,
type: "PUT",
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
data: formData,
enctype: 'multipart/form-data',
processData: false,
contentType: false,
success: function(response) {
var reader = new FileReader();
reader.onload = function(e) {
imgElem.attr("src", e.target.result);
};
reader.readAsDataURL(imageFile); // convert to base64 string
}
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card-body">
<form data-key="0" id="coin-header-0_form" method="POST" action="#" enctype="multipart/form-data">
<input type="file" name="file" id="coin-header-0_file" style="z-index:-1; width: 100%; height: 100%; display: none;" onchange="uploadImage(event, 'coin-header-0_preview', 0)">
<input type="hidden" name="_method" value="PUT">
<meta name="csrf-token" content="7c3s2NmosdK9qzrS10xGAB0rYXw5g41azRjcmPQC">
<img src="http://snapbuilder.com/code_snippet_generator/image_placeholder_generator/60x40/007730/DDDDDD/this%20pict" width="50px" height="50px" alt="icon" id="coin-header-0_preview" onclick="promptImageForUpload('coin-header-0_file');">
</form>
</div>
For now, I am force-updating the preview of the image on the ajax success instead of retrieving it from the updated entity upon successful update, to avoid a second query.
I have the method set to PUT for spoofing in the ajax request and the xsrf token set the headers as well.
Enctype is set to multipart/form-data for files too. I have no clue as to why I don't see the uploaded file anywhere in the request.
Using Laravel Framework 8.25.0, jquery 3.5.1.
Please let me know if any more info is needed, anyone.
I couldn't find any solution on any stackoverflow entry or elsewhere that regards this subject.
Any help is greatly appreciated since I don't really how else to look at this in a debugging approach.
HTML forms do not support PUT, PATCH or DELETE actions. So, when defining PUT, PATCH or DELETE routes that are called from an HTML form, you will need to add a hidden _method field to the form. The value sent with the _method field will be used as the HTTP request method:
<form action="/foo/bar" method="POST">
<input type="hidden" name="_method" value="PUT">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
</form>
You may use the method_field helper to generate the _method input:
{{ method_field('PUT') }}
In the same way, this check may also affect ajax forms. Then in your form switch to the POST method and set the PUT parameter for it to work.
i wrote some code to view my all showing events details using bootstrap modal popup when click read more button. but when i click read more button every response repeats same id.
this is my laravel code
#if(!empty($event))
#foreach($event as $value)
<!-- Single Blog Post -->
<div class="single-blog-post d-flex" id="event_tag">
<div class="post-thumbnail">
<img src="{{asset('images/'.$value->image)}}" alt="">
</div>
<div class="post-content">
<a class="post-title">
#if(strlen($value->title) <= 35)
{{$value->title}}
#else
{{substr($value->title, 0, 35) . '...'}}
#endif
</a>
<div class="post-meta d-flex justify-content-between">
<center><button id="event_button" class="post-cata cata-sm cata-success text_white" data-toggle="modal" data-target="#myModal">Read More</button></center>
</div>
</div>
<input type="hidden" name="event_id" id="event_id" value="{{$value->id}}"></div>
#endforeach
#endif
and this is javascript code to get id and show every id detail.
<script>
$(document).on("click", "#event_button", function() {
var id = $("event_id").val();
console.log(id);
$.ajax({
url: "/event/" + id + "/show",
dataType: "json",
success: function(html) {
$("#event_title").html(html.data.title);
}
});
})
</script>
every time repeats id no 2 when click each event read more button. how can i fix this?
Your code has some mistakes in html too. For example, has fixes ids in html.
'event_id'
'event_button'...
Try this...
<button id="event_button-{!! $value->id !!}" data-target="event_id-{!! $value->id !!}"
<input type="hidden" name="event_id" id="event_id-{!! $value->id !!}"
The code above will fixed the id issue.
Now let's to the JS code... Change the click event:
$(document).on("click", "button.post-cata", function() {
var id = $("#" . $(this).data("target").val();
...
Do you need to associate tags to work with the right value. Avoid to put fixes ids inside a php loop. The html id element must be unique in document.
So, has many ways to do this. In this case, the input hidden fild is not necessary. you can put the id in a attribute in the button tag too.
<button data-id="{!! $value->id !!}...
So in the jquery click event do:
var id = $(this).data('id');
It's more ease and clean.
give class name to button and add attribute to button
<button class="event_button post-cata cata-sm cata-success text_white" data-eventid="{{$value->id}}">Read More</button>
so no need to use hidden input id
now using jQuery :
$(document).on('click','.event_button',function(){
var event_id = $(this).attr("data-eventid");
$("#myModal").modal("show");
$.ajax({
url: "/event/" + event_id+ "/show",
dataType: "json",
success: function(html) {
$("#event_title").html(html.data.title);
}
});
});
I am trying to upload a photo and get a preview of the uploaded image using Spring and Ajax.
I have the following code:
<h3>File Upload</h3>
<ul>
<li>
<form id="upload-form" method="post" enctype="multipart/form-data">
Select a file: <input type="file" name="uploadfile" size="45" accept="*" />
<br>
<input id="submit-button" type="submit" value="Upload" />
</form>
</li>
<li><p>Result: <br><span id="result"></span></p></li>
</ul>
<h3>Show Image</h3>
<ui>
<li>original:<img id="image-o" src="#" alt="original image" /></li>
<li>small: <img id="image-s" src="#" alt="small image" /></li>
<li>medium: <img id="image-m" src="#" alt="medium image" /></li>
<li>large: <img id="image-l" src="#" alt="large image" /></li>
<li>extra large: <img id="image-xl" src="#" alt="extra large image" /></li>
</ui>
<script type="text/javascript">
$(document).ready(function () {
$("#submit-button").on("click", function (event) {
event.preventDefault();
// create an FormData object
var data = new FormData($('#upload-form')[0]);
// disabled the submit button
$("#submit-button").prop("disabled", true);
// post data
$.ajax({
type: "POST",
enctype: 'multipart/form-data',
url: "image/api/upload",
data: data,
processData: false,
contentType: false,
cache: false,
timeout: 600000,
success: function (data) {
// shows server's response
// $("#result").text(data);
console.log("SUCCESS: ", data);
enableSubmitButton();
updateImages(data);
},
error: function (e) {
// shows server's response
// $("#result").text(e.responseText);
console.log("ERROR: ", e);
enableSubmitButton();
updateImages(e.responseText);
}
});
});
});
function enableSubmitButton() {
$("#submit-button").prop("disabled", false);
}
function updateImages(data) {
var url = 'http://localhost:9001/image/api/' + data;
$('#image-s').attr('src',url + '?size=s');
$('#image-m').attr('src',url + '?size=m');
$('#image-l').attr('src',url + '?size=l');
$('#image-xl').attr('src',url + '?size=xl');
$('#image-o').attr('src',url + '?size=o');
}
</script>
And my Java code:
#POST
#Path("/upload")
#Consumes(ExtendedMediaType.MULTIPART_FORM_DATA)
#Produces(ExtendedMediaType.APPLICATION_JSON_UTF8)
#Transactional
public ResponseEntity<Void> uploadImage(#RequestParam("uploadfile") MultipartFile file) {
if (file.getSize() < maxFileSize && validExtensions.contains(file.getContentType())) {
Image image = Image.builder().id(file.getSize()).build();
imageServiceConfigMapper.saveImage(image);
/* FormDataContentDisposition fileDetail = null;
ImageMetadata imageMetadata = buildImageMetadata(fileDetail, image);
imageServiceConfigMapper.saveMetadata(imageMetadata);*/
}
return new ResponseEntity<>(HttpStatus.OK);
When I choose a photo from my PC, it is accepted - see screenshot below:
When I click in upload, my browser gives the following answer:
The JSON looks like this:
BUT the selected picture is not showing:
Am I using a wrong URL?
The address of the site where I got the above screen ends is the one with index.html at the end, but I defined /api/upload as a relative path...
If I open the relative path, I got the following:
Or is it something wrong with the code responsible for the preview?
Sorry, I know there is a tones of similar issues but I could not found anything that hepled. I am quite a beginner...
Sorry for the long post and thanks for the help in advance!
Spring Content can do this and has a getting started guide and git repo with an angularjs based front-end that demonstrates exactly what you are trying to do. The getting started guide is here.
I've searched for an answer but could not find any. Maybe someone here can point me to the right direction.
I have a simple modal form (bootstrap). It's meant to work like this.
You enter the form and click Send. The form-info is sent to e-mailadress. When mail is sent new modal with confirmation is displayed.
I've tried to implement this solution: Bootstrap Modal ajaxified
So far i have this:
The modal:
<div class="hide fade modal" id="input-modal">
<form class="form-horizontal well" data-async data-target="#input-modal" action="/some-endpoint" method="POST">
<fieldset>
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Modal header</h3>
</div>
<div class="modal-body">
<label>Name</label>
<input id="name" type="text" placeholder="Type your name...">
</div>
<div class="modal-footer">
Cancel
<button type="submit" class="btn btn-primary" value="send"/>Send</button>
</div>
</fieldset>
</form>
The Javascript:
jQuery(function($) {
$('body').on('submit','form[data-async]', function(event) {
alert('submit Event');
var $form = $(this);
var $target = $($form.attr('data-target'));
$.ajax({
type: $form.attr('method'),
url: $form.attr('action'),
data: $form.serialize(),
success: function(data, status) {
$target.html(data);
}
});
event.preventDefault();
});
});
But I need help with sending the input by mail and also sent info back to modal as a confirmation.
I've tried to solve this by myself for several days now, but now I've given up.
If you're using jQuery >= 1.5 look at the documentation here. This will provide you with a place to handle your new modal when the AJAX call returns. So your code would look something like this.
jQuery(function($) {
$('body').on('submit','form[data-async]', function(event) {
alert('submit Event');
var $form = $(this);
var $target = $($form.attr('data-target'));
$.ajax({
type: $form.attr('method'),
url: $form.attr('action'),
data: $form.serialize()
}).done(function(data){
//pop your modal here
$('#your-new-modal').modal('show')
});
event.preventDefault();
});
This is assuming you plan to send the email server side as you can't send it from Javascript. In your example you would have changed the HTML content of the tag to the data returned from the AJAX call instead of opening a new modal. You can find documentation on opening the new modal via Javascript here.
Did not run this so there may be typos.
I am stuck with the following: I have a simple form on index.phpwith one input field. On button click the form makes a jquery ajax request to lookup.php which returns some data. This data is shown on index.php. So far nothing special and it works when i use the keyboard.
Now when i use the barcode scanner it doesn't work, with some trial and error it looks like the barcode scanner uses the "submit" handler. But in my case the ajax request is handled by
$("#btnSubmit").on("click",
and button btnSubmit is of the type=button and not submit.
How can i fix this so the barcode scanner is also making the ajax request?
jquery submit with $.ajax doesn't seem to work
If you have a simple form like:
<div id="status"></div>
<form action="">
<input id="foo"/>
<input type="submit" value="Submit">
</form>
You can do:
$("form").submit(function(e) {
e.preventDefault();
$.ajax({
url: "lookup.php",
type: "POST", // Can change this to get if required
data: { foo: $("#foo").val(); },
success: function(data) {
$("#status").html(data);
},
error: function(jqXHR, textStatus, errorThrown) {
$("#status").text(textStatus);
}
});
});
