Javascript TinyMCE-本地图像上载

每次将本地图像上传到TinyMCE表单时，我都会遇到一个奇怪的错误-页面重新加载。使用TinyMCE 4.7.13和ASP MVC

我的代码：

tinymce.init({
    selector: '.formatedtext',
    branding: false,
    plugins: 'code,emoticons,lists,advlist,autolink,autoresize,autosave,codesample,textcolor,colorpicker,fullscreen,hr,image,link,media,preview,searchreplace,table,textpattern,wordcount,imagetools',
    toolbar: 'image,code,emoticons,bulllist,numlist,restoredraft,codesample,forecolor,backcolor,fullscreen,preview,searchreplace',
    width: '100%',
    language: 'cs',
    browser_spellcheck: true,
    image_advtab: true,
    paste_data_images: true,
    automatic_uploads: true,
    file_picker_types: 'image',
    images_upload_url: '/TinyMce/TinyMceUpload'
});

TinyMce控制器中的操作：

[HttpPost]
public ActionResult TinyMceUpload(HttpPostedFileBase file) {
    //Response.AppendHeader("Access-Control-Allow-Origin", "*");

    string loc = SaveFile(Server.MapPath("~/Uploads/UsersContent/"), file);

    return Json(new {
        location = loc
    });
}

其中定义了SaveFile并正在使用

问题是图像已加载并成功保存，但一旦加载，页面将重新加载。

Index.cshtml

    <script>
        tinymce.init({
            selector: "textarea",
            theme: "modern",
            paste_data_images: true,
            plugins: [
                "advlist autolink lists link image charmap print preview hr anchor pagebreak",
                "searchreplace wordcount visualblocks visualchars code fullscreen",
                "insertdatetime media nonbreaking save table contextmenu directionality",
                "emoticons template paste textcolor colorpicker textpattern"
            ],
            toolbar1: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image",
            toolbar2: "print preview media | forecolor backcolor emoticons",
            image_advtab: true,
            file_picker_callback: function (callback, value, meta) {
                if (meta.filetype == 'image') {
                    $('#upload').trigger('click');
                    $('#upload').on('change', function () {
                        var file = this.files[0];
                        var reader = new FileReader();
                        reader.onload = function (e) {
                            callback(e.target.result, {
                                alt: ''
                            });
                        };
                        reader.readAsDataURL(file);
                    });
                }
            },

        });

    </script>

并直接显示在Base64编码器的textarea图像中，如果上载图像

否，则取消文件选择器回调
