Я использую html5 dropzone для загрузки изображения с помощью javascript

var dropZone = $('#dropZone'), maxFileSize = 1000000, img_id = 0; // if (typeof (window.FileReader) == 'undefined') { dropZone.text('NO BROWSER SUPPORT!'); dropZone.addClass('error'); } // dropZone[0].ondragover = function () { dropZone.addClass('hover'); return false; }; // dropZone[0].ondragleave = function () { dropZone.removeClass('hover'); return false; }; // dropZone[0].ondrop = function (event) { event.preventDefault(); dropZone.removeClass('hover'); dropZone.addClass('drop'); var file = event.dataTransfer.files[0]; // if (file.size > maxFileSize) { dropZone.text('SO BIG FILE!'); dropZone.addClass('error'); return false; } // var xhr = new XMLHttpRequest(); xhr.upload.addEventListener('progress', uploadProgress, false); xhr.onreadystatechange = stateChange; xhr.open('POST', '/admin/admin.api.php'); xhr.setRequestHeader('X-FILE-NAME', file.name); xhr.send(file); }; // function uploadProgress(event) { var percent = parseInt(event.loaded / event.total * 100); dropZone.text('Загрузка: ' + percent + '%'); } // function stateChange(event) { if (event.target.readyState == 4) { if (event.target.status == 200) { dropZone.text('SUCCESS!'); } else { dropZone.text('FAIL!'); dropZone.addClass('error'); } } }
