ASP.NET MVC中的Ajax FileUpload和JQuery formData

您可以使用Jquery Ajax代替

 <script> function SubmitButtonOnclick() {      var formData= new FormData();     var imagefile=document.getElementById("imageFile").files[0];     var coverfile=document.getElementById("coverFile").files[0];     formData.append("imageFile",imageFile);     formData.append("coverFile",coverFile);     var xhr = new XMLHttpRequest();     xhr.open("POST", "/Profile/EditProfile", true);     xhr.addEventListener("load", function (evt) { UploadComplete(evt); }, false);     xhr.addEventListener("error", function (evt) { UploadFailed(evt); }, false);     xhr.send(formData); }      function UploadComplete(evt) {        if (evt.target.status == 200)      alert("Logo uploaded successfully.");        else       alert("Error Uploading File");        }    function UploadFailed(evt) {        alert("There was an error attempting to upload the file.");    } </script>

这对我有用！

您的脚本有变化

 function SubmitButtonOnclick() {        var formData = new FormData();        var file = document.getElementById("imageFile").files[0];        var file1 = document.getElementById("coverFile").files[0];        formData.append("imageFile", file);        formData.append("coverfile", file1);        $.ajax({ type: "POST", url: '@Url.Action("EditProfile","Default1")', data: formData, dataType: 'json', contentType: false, processdata: false, success: function (response) {     $('#GeneralSection').html(response.responseText); }, error: function (error) {     $('#GeneralSection').html(error.responseText); }        });    }
