File upload progress bar with jQuery

I've done this with jQuery only:

$.ajax({ xhr: function() { var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt) { if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; percentComplete = parseInt(percentComplete * 100); console.log(percentComplete); if (percentComplete === 100) { } } }, false); return xhr; }, url: posturlfile, type: "POST", data: JSON.stringify(fileuploaddata), contentType: "application/json", dataType: "json", success: function(result) { console.log(result); } }); 

I have used the following in my project. you can try too.

ajax = new XMLHttpRequest(); ajax.onreadystatechange = function () { if (ajax.status) { if (ajax.status == 200 && (ajax.readyState == 4)){ //To do tasks if any, when upload is completed } } } ajax.upload.addEventListener("progress", function (event) { var percent = (event.loaded / event.total) * 100; //**percent** variable can be used for modifying the length of your progress bar. console.log(percent); }); ajax.open("POST", 'your file upload link', true); ajax.send(formData); //ajax.send is for uploading form data. 

check this out: http://hayageek.com/docs/jquery-upload-file.php I've found it accidentally on the net.

If you are using jquery on your project, and do not want to implement the upload mechanism from scratch, you can use https://github.com/blueimp/jQuery-File-Upload.

They have a very nice api with multiple file selection, drag&drop support, progress bar, validation and preview images, cross-domain support, chunked and resumable file uploads. And they have sample scripts for multiple server languages(node, php, python and go).

Demo url: https://blueimp.github.io/jQuery-File-Upload/.

Here is a more complete looking jquery 1.11.x $.ajax() usage:

<script type="text/javascript"> function uploadProgressHandler(event) { $("#loaded_n_total").html("Uploaded " + event.loaded + " bytes of " + event.total); var percent = (event.loaded / event.total) * 100; var progress = Math.round(percent); $("#uploadProgressBar").html(progress + " percent na ang progress"); $("#uploadProgressBar").css("width", progress + "%"); $("#status").html(progress + "% uploaded... please wait"); } function loadHandler(event) { $("#status").html(event.target.responseText); $("#uploadProgressBar").css("width", "0%"); } function errorHandler(event) { $("#status").html("Upload Failed"); } function abortHandler(event) { $("#status").html("Upload Aborted"); } $("#uploadFile").click(function (event) { event.preventDefault(); var file = $("#fileUpload")[0].files[0]; var formData = new FormData(); formData.append("file1", file); $.ajax({ url: 'http://testarea.local/UploadWithProgressBar1/file_upload_parser.php', method: 'POST', type: 'POST', data: formData, contentType: false, processData: false, xhr: function () { var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", uploadProgressHandler, false ); xhr.addEventListener("load", loadHandler, false); xhr.addEventListener("error", errorHandler, false); xhr.addEventListener("abort", abortHandler, false); return xhr; } }); }); </script> 

This solved my problem

var url = "http://localhost/tech1/index.php?route=app/upload/ajax"; $.ajax({ xhr: function() { var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt) { if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; percentComplete = parseInt(percentComplete * 100); var $link = $('.'+ids); var $img = $link.find('i'); $link.html('Uploading..('+percentComplete+'%)'); $link.append($img); } }, false); return xhr; }, url: url, type: "POST", data: JSON.stringify(uploaddata), contentType: "application/json", dataType: "json", success: function(result) { console.log(result); } }); 

Kathir's answer is great as he solves that problem with just jQuery. I just wanted to make some additions to his answer to work his code with a beautiful HTML progress bar:

$.ajax({ xhr: function() { var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt) { if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; percentComplete = parseInt(percentComplete * 100); $('.progress-bar').width(percentComplete+'%'); $('.progress-bar').html(percentComplete+'%'); } }, false); return xhr; }, url: posturlfile, type: "POST", data: JSON.stringify(fileuploaddata), contentType: "application/json", dataType: "json", success: function(result) { console.log(result); } }); 

Here is the HTML code of progress bar, I used Bootstrap 3 for the progress bar element:

<div class="progress" style="display:none;"> <div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" style="width:0%"> 0% </div> </div> 

this is a simple way............

/* ajax progresss */ $(document).on('submit', '#sync', function () { $.ajax({ type: 'POST', url: site_url + "sync/import_past_data", data: {}, beforeSend: function(XMLHttpRequest) { console.log('2'); //Upload progress XMLHttpRequest.upload.addEventListener("progress", function(evt){ if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; $( ".jquery-uploadbar-selector" ).progressbar({ value: percentComplete }); //jquery progress bar for upload //incase you wanted an upload bar } }, false); //Download progress XMLHttpRequest.addEventListener("progress", function(evt){ if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; $( ".jquery-downloadbar-selector" ).progressbar({ value: percentComplete }); //jquery progress bar for download or in other words The real answer for question } }, false); }, success: function(data){ //Here goes the end of what you have done.. I would just type.. console.log('1'); } }); }); /* end of progress */
