JavaEE_Mybatis_SpringMVC (异步上传)SpringMvc文件上传 通过ajaxupfileload.js
最近博主又去研究文件上传了
这次的文件上传是通过ajax上传文件。(看了下ajaxupfileload.js,主要是通过 iframe 提交的数据。)
需求就是在新增用户的时候通过异步上传表单和图片, 功能如图所示：

最终历经了千辛万苦终于研究了出来,主要用到了 ajaxupfileload.js 插件。
ajaxupfileload.js 提交数据的时候需要以JSON格式提交表单数据，由于原生的 javaScript,Jquery 不支持将表单数据转换成JSON格式的数据，博主又用了另一个插件，将表单数据转换为JSON格式进行提交。
ajaxupfileload.js 里面需要用到 JQuery.handleError 函数，该函数在JQuery高版本中被移除了，我将其放到 ajaxupfileload.js，作为jquery的扩展函数
主要用到的插件下载地址 http://pan.baidu.com/s/1slnAdMt
1.异步提交数据 ajaxupfileload.js
2.将表单转换为JSON formToJson.js
主要步骤
1.将表单数据转换为JSON格式
2.利用ajaxupfileload.js 将数据异步提交到服务器上
3.后台接收数据并处理 参考文章 SpringMVC后台接收数据 http://blog.csdn.net/u010003835/article/details/51000077
前端js --- 通过js提交数据
ajaxupfileload + 表单转JSON
/*添加或者更新结果*/
function saveOrUpdateForm(){
var checkImageFlag = checkImageFileType(); //校验图片是否是正确的格式
var flag = $("#addOrUpdateModalForm").validationAjax(); //对表单数据的校验
flag = checkImageFlag && flag;
//alert(flag);
if(flag){
var postUrl = appCtx+"userInfo/insertOrUpdate.do";
var params = $("#addOrUpdateModalForm").serializeJson(); //将表单数据转换为JSON
//alert(params.name);
$("#loading").modal("show");
function ajaxFileUpload() {
$.ajaxFileUpload
(
{
url: postUrl, //用于文件上传的服务器端请求地址
secureuri: false, //是否需要安全协议，一般设置为false
fileElementId: 'userImage', //文件上传域的ID
dataType: 'json', //返回值类型 一般设置为json
data: params, //需要传递JSON对象如这种 {'name':'hahah'}
success: function (data, status) //服务器成功响应处理函数
{
//alert('上传成功');
},
error: function (data, status, e)//服务器响应失败处理函数
{
//alert(e);
doSuccess();
//成功后，模态框的状态
successModalStatus(oneRowModalCloseBtn,oneRowModalSaveBtn,oneRowModalUpdateBtn,oneRowModal,oneRowModalTitle,oneRowModalBody);
//成功后，刷新表单
succesListFormReflush();
}
}
)
return false;
}
ajaxFileUpload(); //将头像和表单数据同时上传
$("#loading").modal("hide");
}
}
由于需要上传图片，前端对于图片的校验：
/*校验上传文件的数据类型，前端校验，检查文件的文件类型*/
function checkImageFileType(){
var correctType = new Array("png","jpeg","gif","jpg","bmp"); //正确的图片格式
var oldImageUrl = $("#imageUrl").get(0).value;
var fileName = $("#userImage").get(0).value;
//如果是之前有图片,现在不上传新图片,不需要校验
if((oldImageUrl!=null||oldImageUrl!="")&&(fileName==null||fileName=="")){
return true;
}
//对上传的图片进行校验
var fileType = fileName.substr(fileName.lastIndexOf(".")+1);
var fileTypeLow = fileType.toLowerCase(); //将图片格式的名字转换为小写
for(index in correctType){
if(fileTypeLow == correctType[index]){
//alert("正确的图片格式");
return true;
}
}
//错误信息的提示
var infoParent = document.getElementById("checkImageInformation");
var tips = document.createElement("div");
tips.id = "checkImageTypeTips";
tips.style.width = "200px";
tips.style.color = "red";
tips.innerHTML = "数据类型不满足要求,请上传 png,jpeg,gif,jpg,bmp类型的图片";
infoParent.appendChild(tips);
return false;
}
