使用jQuery上传多部分文件

Question

有没有办法在JSP + java中使用jQuery上传multipart文件.在jQuery AJAX中执行时出错.

$.ajax({
    type: "POST",
    url: "${pageContext.request.contextPath}/users/imageUpload/" + $imageUpload + "/" + $userId??,
    contentType: "multipart/form-data",
    processData: false,
}).done(function(data) {}).fail(function(data) {
    alert("Ooopss..! Something Bad Happened.!");
});

Answer 1

$("input:file").change(function(objEvent) {
    var objFormData = new FormData();
    // GET FILE OBJECT 
    var objFile = $(this)[0].files[0];
    // APPEND FILE TO POST DATA
    objFormData.append('userfile', objFile);
    $.ajax({
        url: 'Here Your Server-Url'
        type: 'POST',
        contentType: false,
        data: objFormData,
        //JQUERY CONVERT THE FILES ARRAYS INTO STRINGS.SO processData:false
        processData: false,
        success: function(data) {}
    });
});
