MVC js动态生成from提交数据然后生成文件下载

前台： 点击触发下面事件

var turnForm = document.createElement("form"); //一定要加入到body中！！ document.body.appendChild(turnForm); turnForm.method = 'post'; turnForm.action = 'GetCSV'; turnForm.target = '_blank'; //创建隐藏表单 var newElement = document.createElement("input"); newElement.setAttribute("name", "csvFrom"); newElement.setAttribute("type", "hidden"); newElement.setAttribute("value", JSON.stringify(saveSiteArray)); turnForm.appendChild(newElement);

turnForm.submit();

 

后台接收：

public ActionResult GetCSV(FormCollection form) { try { List<AspSiteList> urlList = JsonToObj(form["csvFrom"], typeof(List<AspSiteList>)) as List<AspSiteList>; List<string> newUrlList = new List<string>();

foreach (var item in urlList) { string newUrl = item.ClientId + " " + item.UneiUserName + " " + item.AsId + " " + item.AsNm + " " + item.Url; newUrlList.Add(newUrl); } string newString = string.Join("\r\n", newUrlList);

 Encoding encoder = Encoding.UTF8;

byte[] bytes = encoder.GetBytes(newString);

Response.Charset = "UTF-8";

Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8"); Response.ContentType = "application/octet-stream";

Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode("demo.csv")); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); return new EmptyResult(); } catch (Exception) {

throw; } }
