2、); uploadAndSubmit(product); var div = document.getElementById(preview + product); var fileName = file.value; /upload(); if (file.files) var i = 0; var funAppendImage = function () var _file = file.filesi; if (_file) var reader = new FileReader() reader.onload = function (evt) fileName = _;

3、 div.innerHTML += div class=col-xs-6 col-md-3a style=float:right;cursor:pointer; onclick=del(this)X/adiv class=thumbnailimg id=imghead + product + fileName + /div/div; var img = document.getElementById(imghead + product + fileName); img.src = evt.target.result; i+; funAppendImage(); reader.readAsDat

4、aURL(_file); ; funAppendImage(); $(#coverBg).show(); $(#coverDiv).show(); /$(#uploadFrm + product).submit(); 上傳： var access_token = *; var baseUrl = function uploadAndSubmit(product) console.log(start uploadAndSubmit); if (typeof FileReader = undefined) alert(你的掃瞄器不支持FileReader接口！); var taskName = $

5、(#txtTask).val() + - + $(#txtTask2).val(); var form = document.formsuploadFrm + product; console.log(form: + form); var fileCtrl = filectrl + product; console.log(filectrl: + fileCtrl); /if (formfileCtrl.files.length 0) console.log($(#filectrl + product)0); if ($(#filectrl + product)0.files.length 0

6、) for (var i = 0; i $(#filectrl + product)0.files.length; i+) var file = formfileCtrl.filesi; console.log(); var filePath = %2fapps%2fwp2pcs%2f + taskName + %2f + ; console.log(add exif info to db); getExifIinfo(taskName, file, product, filePath); /document.getElementById(bytesRead

7、).textContent = file.size; console.log(start XMLHttpRequest); var xhr = new XMLHttpRequest(); console.log(access_token); var url = baseUrl + file?method=uploadpath=%2fapps%2fwp2pcs%2f + taskName + %2f + + access_token= + access_token + ondup=overwritecount= + i; console.log(url); xhr.open(

8、POST, url, true); var formData = new FormData(); formData.append(file, file); console.log(onreadystatechange); xhr.onreadystatechange = function () console.log(onreadystatechange start); /console.log(xhr.status); if (xhr.readyState = 4) if (xhr.status = 200) console.log(upload complete); console.log

9、(response: + xhr.responseText); var result = $.parseJSON(xhr.responseText); if (result.hasOwnProperty(path) $(#reusltMsg).append(div class=alert alert-success role=alert 上傳勝利./div); else $(#reusltMsg).append(div class=alert alert-danger role=alert 上傳失敗./div); else $(#reusltMsg).append(div class=alert alert-danger role=alert 上傳失敗(200)./
