javascript - 如何接受仅添加媒体文件(视频和照片)和“无所有文件”部分

Question

我在 html 页面有这个

<input type="file" id="ajax-upload-id-1508413400253" name="Media" accept="video/*,image/*" 
style="position: absolute; cursor: pointer; top: 0px; width: 100%; height: 
100%; left: 0px; z-index: 100; opacity: 0;">

在 .js

 manageMedia_Uploader = $("#fileuploader").uploadFile({
            url: "/Ajax/JsonProvider?Method=SaveMedia",
            fileName: "Media",
            autoSubmit: false,
            multiple: false,
            acceptFiles: "video/*,image/*",
            dynamicFormData: function () {
                return { MediaFriendlyName: $("#ManageMedia-MediaFriendlyName").val(), MediaID: mediaID }
            },


SaveMedia: function (mediaID) {

        if (mediaID == 0) {
            manageMedia_Uploader.startUpload();
        } else {
             //util
        }
    },

我的问题是我只想添加图片和视频而不添加其他内容。感谢这段代码在选择文件时给了我两个选项。自定义文件和所有文件。

acceptFiles: "video/*,image/*",

如何阻止“所有文件”部分？只会出现自定义文件？

首先您需要添加 input type="file"属性，以接受媒体文件，您可以这样做:HTML

<input type="file" id="ajax-upload-id-1508413400253" name="Media" accept="audio/*,video/*,image/*" 
style="position: absolute; cursor: pointer; top: 0px; width: 100%; height: 
100%; left: 0px; z-index: 100; opacity: 0;">

JS

manageMedia_Uploader = $("#fileuploader").uploadFile({
            url: "/Ajax/JsonProvider?Method=SaveMedia",
            fileName: "Media",
            autoSubmit: false,
            multiple: false,
            acceptFiles: "image/*, video/*",
            dynamicFormData: function () {
                return { MediaFriendlyName: $("#ManageMedia-MediaFriendlyName").val(), MediaID: mediaID }
            },


SaveMedia: function (mediaID) {

        if (mediaID == 0) {
            manageMedia_Uploader.startUpload();
        } else {
             //util
        }
    },
