We use Simple Upload jQuery plugin to upload the file using the plugin. Here is full code sample example with the plugin.

How to install plugin in your project

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

How to use plugin:

First, bind the plugin to your HTML file element.

$('input[type=file]').change(function(){

            $(this).simpleUpload("YOUR_BACKEND_URL", {

                allowedExts: ["jpg", "jpeg", "jpe", "jif", "jfif", "jfi", "png", "gif"],
                allowedTypes: ["image/pjpeg", "image/jpeg", "image/png", "image/x-png", "image/gif", "image/x-gif"],
                maxFileSize: 10000000, //10MB in bytes

                start: function(file){
                    //upload started
                    this.block = $('<div class="block"></div>');
                    this.progressBar = $('<div class="progressBar"></div>');
                    this.cancelButton = $('<div class="cancelButton">x</div>');
                    var that = this;

                    this.cancelButton.click(function(){
                        that.upload.cancel();
                        //now, the cancel callback will be called
                    });

                    this.block.append(this.progressBar).append(this.cancelButton);
                    $('#uploads').append(this.block);

                },
                progress: function(progress){
                    //received progress
                    this.progressBar.width(progress + "%");
                },
                success: function(data){
                    //upload successful
                    this.progressBar.remove();
                    this.cancelButton.remove();
                    this.block.remove();
                    var data = JSON.parse(data);
                    if (data.status == 'success') {
                        var htm = '';
                        htm += '<div class="col-md-3 mg-t-30 ui-state-default" id="image_'+data.imageId +'" data-id="'+data.imageId +'">'+
