您可以使用formdata更新代碼或任何jquery文件上傳插件https://stackoverflow.com/a/204271/876739

您可以看到這篇文章https://stackoverflow.com/a/41458116/876739

 $(document).on('click', '#upload', function(e) { e.preventDefault(); var fd = new FormData(); var file = $('#my_file')[0].files[0]; fd.append('file', file); fd.append('userId', $('#userid').val()); console.log("hi"); $.ajax({ url: 'UploadPic', data: fd, type: "POST", contentType: false, processData: false, success: function(dd) { alert("sucessfully Uploaded") } }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="file" id="my_file"> <input type="hidden" id="userid" /> <input type="button" id="upload" value="Upload" />
