asp.net - Upload file using jQuery and post it to Controller -

-

i'm wondering if possible @ upload file posting controller action in asp.net mvc. dialog upload form dynamically generated , inside jquery dialog in case.

i'm aware of file input element i'm not sure how send file controller action, not sure how set action parameter

your action should this:

[httppost] public actionresult upload(httppostedfilebase file) {    if (file.contentlength > 0) {     var filename = path.getfilename(file.filename);     var path = path.combine(server.mappath("~/app_data/uploads"), filename);     file.saveas(path);   }    return redirecttoaction("index"); }

then using jquery dialog file upload:

$dialog.dialog("option", "buttons", {     "save": function () {         var dlg = $(this);         var formdata = new formdata($("#" + formname)[0]);         $.ajax({             url: /controller/upload,             type: 'post',             data: formdata,             processdata: false,              contenttype: false,             success: function (response, textstatus, xhr) {             ...                 }             },             error: function (xhr, status, error) {                 ....             }         });     },     "cancel": function () {         $(this).dialog("close");         $(this).empty();     }  });
