PDFTron XOD 查看器未在 ASP.NET Core MVC 6 Razor 视图上加载 XOD 文件。检查浏览器控制台显示错误:“浏览器链接:无法调用返回值回调:TypeError:无法获取未定义或空引用的属性'文件'”。
浏览器显示消息:“请”代替 WebViewer 控件。我看到这来自代码部分的 PDFTron WebViewer.js 文件,如下所示:
else {
var supportErrorArray = new Array();
supportErrorArray.push("Please");
if (allowHTML5) {
supportErrorArray.push("use an HTML5 compatible browser");
if (allowSilverlight || allowFlash) {
supportErrorArray.push("or");
}
me.selectedType is none
从WebVeiwer.js
我在WebViewer.js
文件中发出警报时开始。PDFTron XODViewer 不支持 ASP.NET Core MVC 6 吗?
我使用一种解决方法通过检查来更正WebViewer.js
脚本:
if(me.selectedType == null)
{
if (this.options.html5Options) {
$.extend(this.options, this.options.html5Options);
}
me._createHTML5();
}
MVC 6 Razor View (Document/Index.cshtml) 标记如下:-
@model XODViewer.Models.Document
@{
ViewBag.Title = "Document";
}
<script src="@Url.Content("~/lib/jquery/dist/jquery.js")"></script>
<script src="@Url.Content("~/lib/WebViewer.js")"></script>
<style>
#viewer {
width: 1024px;
height: 600px;
}
</style>
<script>
$(function () {
var docName = '@Html.Raw(Model.DocumentName)';
var viewerElement = document.getElementById('viewer');
var myWebViewer = new PDFTron.WebViewer({
path: '../../lib',
type: '../../lib/html5',
documentType: "xod",
initialDoc: "../../XodFiles/GettingStarted.xod",
config: '',
streaming: false,
enableAnnotations: false,
enableOfflineMode: false,
enableReadOnlyMode: true
}, viewerElement);
});
</script>
@Html.Raw(ViewBag.Message)
<div id="viewer" style="padding:10px; word-wrap:break-word;">
</div>
ASP.NET Core MVC 6 解决方案如随附的屏幕截图所示。
我已经为 XOD 设置了如下内容类型:-
// Set up custom content types -associating file extension to MIME type
var provider = new FileExtensionContentTypeProvider();
// Add new mappings
provider.Mappings[".json"] = "application/json";
provider.Mappings[".woff"] = "application/font-woff";
provider.Mappings[".res"] = "text/plain";
provider.Mappings[".nmf"] = "text/plain";
provider.Mappings[".pexe"] = "text/plain";
provider.Mappings[".mem"] = "text/plain";
provider.Mappings[".brotli"] = "text/plain";
provider.Mappings[".xod"] = "application/vnd.ms-xpsdocument";
// Remove MP4 videos.
//provider.Mappings.Remove(".mp4");
app.UseStaticFiles(new StaticFileOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "XodFiles")),
RequestPath = new PathString("/XodFiles"),
ContentTypeProvider = provider
});
最后,在运行解决方案时,不会显示 XOD Viewer 或 XOD 文档。运行页面和浏览器控制台的解决方案截图如下所示。
