问题：
用jquery.form.js异步提交表单时，接收的是JSON格式的数据，但是奇怪的是在IE中提示下载文件，其他浏览器中一切正常，下载后，里面的内容就是在控制器中返回的数据。
解决方案：
原返回值设定：context.Response.ContentType = "application/json";
尝试： context.Response.ContentType = "text/xml;"; 失败
后来试了下：context.Response.ContentType = "text/plain;charset=UTF-8";
例子
public ActionResult ShangChuanEmpPhoto()
{
WebImage pic = GetImageFromRequest();
//WebImage pic = new WebImage(Request.InputStream);
int MaxWidth = 600;
int MaxHeight = 400;
int MinWidth = 160;
int MinHeight = 160;
if (pic != null)
{
//string imageName = getTalentId();
string imageName = MyClasses.KwstuLib.ClassesLib.GetIdByTime();
string imageFormat = pic.ImageFormat;
if (pic.Width > MaxWidth || pic.Height > MaxHeight) pic.Resize(MaxWidth, MaxHeight, true, true);
if (pic.Width < MinWidth || pic.Height < MinHeight) pic.Resize(MinWidth, MinHeight, true, false);
pic.Save(getUploadPhotoPath() + "Temp＼＼" + imageName);
TouXiangInfo touxiang = new TouXiangInfo()
{
w_full = pic.Width,
h_full = pic.Height,
tempfilename = imageName + "." + imageFormat
};
return Json(new
{
List = touxiang
}, "text/html");
}
return Content("0");
}
视图中：
//上传照片
$("#uploadfile").change(function () {
var filepath = $("#uploadfile").val();
if (filepath == "") return false;
var extStart = filepath.lastIndexOf(".");
var ext = filepath.substring(extStart, filepath.length).toUpperCase();
if (ext != ".BMP" && ext != ".PNG" && ext != ".GIF" && ext != ".JPG" && ext != ".JPEG") {
alert("图片限于bmp,png,gif,jpeg,jpg格式");
return false;
}
$("#ShangChuanTuPianForm").submit();
});
$("#ShangChuanTuPianForm").ajaxForm({
beforeSend: function () {
$("#shangchuan").attr("disabled", "disabled").val("正在上传");
},
dataType: "html",//默认就是html类型，不写对火狐有影响
cache: false,
success: function (response) {
if (response != "0") {
responseText = JSON.parse(response); //把html转换成json类型
$.each(responseText, function (index, item) {
$("#TuPianImg").append("");
$("#tempfilename").val(item.tempfilename);
$("#w_full").val(item.w_full);
$("#h_full").val(item.h_full);
});
$("#TempImage").Jcrop({
//aspectRatio: 0.7692,
aspectRatio: 1,
setSelect: [0, 0, 160, 160],
onChange: changeCropInfo
}, function () {
JcropAPI = this;
});
$("#ShangChuanTuPianKongJian").hide();
$("#CaiJianTuPianKongJian").show();
}
}
});
