I would like to insert this script to nuxtJS project and I want it to load dynamically by page.

The important thing is tagId: 'xxxxx' this should be change dynamically by page. for example,
wwww.sample.com/shop1 will load tagId: 'shop_tag1'
wwww.sample.com/shop2 will load tagId: 'shop_tag2'
What kind of tracker is this ? If it does not have any way of setting it app-wise, I guess that you need to have a middleware that is running your function and grabbing the dynamic part from each page.
This can be helpful: https://nuxtjs.org/docs/2.x/directory-structure/middleware/
Also, I did found some issues on using a middleware in a layout, but maybe it's just me, if it does work on your side, you could just dump your js there too.
I like to display images in a content in vue. The content ist stored in the db.
I use vue-auth-image
If i put the code <img v-auth-image="api/media/1"> in to the template section, it works well.
But whit the following code, it doesn't work:
<div v-html="issue.body" >
</div>
The response from the ajax call is "body": "<img src='api/media/17'>",
How can i display the image in the content?
I have a partial view rendered with an Html.Action() that I want to refresh on a button click. I've tried AJAX requests, but the data I'm passing back and forth exceeds the maximum length for JSON.
The basic structure of the page looks like:
<html>
<head>
...
</head>
<body>
<div>
#Html.Action("DisplayBox")
</div>
<div>
<input type="button" id="RefreshButton" value="Refresh Box" />
</div>
</body>
</html>
The reason why I'm asking for a method other than an AJAX request is that the partial I'm rendering is a PDF object:
#model byte[]
#{
String base64EncodedPDF = System.Convert.ToBase64String(Model);
Layout = null;
}
<object data="data:application/pdf;base64,#base64EncodedPDF"
width="900" height="900" type="application/pdf"></object>
Thus, the data passed to the partial view for rendering is too big to put in an AJAX request. On button click, I want to be able to execute the controller action and have the results update the partial with new data. Is there any way of doing this?
You have to load the HTML with the link to the controller that generate the PDF or generate the file on the server side, host it and return the URL of this PDF, then, javascript can redirect user to that file.
I don't think that returning file trough AJAX is really not a good practice!
I've created an Web API controller in my MVC project. Whenever I try to POST to this controller, it try's to initiate a File download, and I am not sure why. It happens if I navigate to the API controller via URL or if it's done via a Form post.
It's a very simple scenario where an File is to be uploaded via a post.
Here is the controller code. Any ideas?
public class UploadController : ApiController
{
public async Task<List<string>> Post()
{
// Verify that this is an HTML Form file upload request
if (!Request.Content.IsMimeMultipartContent("form-data"))
{
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
// Create a stream provider for setting up output streams that saves the output under c:\tmp\uploads
// If you want full control over how the stream is saved then derive from MultipartFormDataStreamProvider
// and override what you need.
MultipartFormDataStreamProvider streamProvider = new MultipartFormDataStreamProvider("c:\\tmp\\");
var task = await Request.Content.ReadAsMultipartAsync(streamProvider);
return new List<string>();
}
Here is the client code:
<!DOCTYPE HTML>
<html>
<head>
<title>HTML5 Multiple File Upload Sample</title>
</head>
<body>
<form action="http://localhost:8080/api/upload" enctype="multipart/form-data" method="POST">
What is your name?
<input name="submitter" size="40" type="text"><br>
What files are you uploading?
<input name="data" type=file multiple>
<br>
<input type="submit" />
</form>
</body>
</html>
I suspect that you are using Internet Explorer to test this example, aren't you? But this browser always prompts for download when the server sends JSON (yeah IE sucks like hell, we all know that, please use a real web browser when you are doing web development). Your controller action returns JSON that IE is incapable of displaying inline and it asks you to save it on the client. I don't know what else did you expect? Your controller action returns an empty array as JSON. You have an HTML form to upload a file and the result of this file upload is an empty JSON array that IE doesn't know how to handle.
If you use an HTML client form you probably wanna return HTML from this API controller action, right?
I got the DurandalJS StarterKit template on VS2012... All works great...
But in some views I need to do something like that:
#if (Roles.IsUserInRole("Administrators"))
{
<p>Test</p>
}
However with durandal all my views are '.html' files... Is that possible to use '.cshtml' files to access some information like that?
Or is there any other way to do that with durandal?

I am doing it like this:
Create a generic controller for Durandal views:
public class DurandalViewController : Controller
{
//
// GET: /App/views/{viewName}.html
[HttpGet]
public ActionResult Get(string viewName)
{
return View("~/App/views/" + viewName + ".cshtml");
}
}
Register a route:
routes.MapRoute(
name: "Durandal App Views",
url: "App/views/{viewName}.html",
defaults: new { controller = "DurandalView", action = "Get" }
);
Copy Views/web.config to /App/views/web.config (so Razor views work in this location).
This lets me use the normal Durandal conventions (even the html extension for views), and put durandal views as cshtml files in their normal location without adding any more server code.
If you also have static html views, you can also place the cshtml views in a subfolder or use the normal MVC /Views folder.
I wouldn't recommend using ASP.NET MVC with Durandal.
What you are probably looking to do is use the Razor view engine (to get the benefits of a compiler, strong typing etc.) which exists independently from ASP.NET MVC. Just WebAPI for data I/O is more than enough to very efficiently create a Durandal.js application.
If you are interested in using Razor/CSHTML with Durandal and Knockout there is an open source option out there called FluentKnockoutHelpers that may be exactly what you are looking for. It offers much of the 'nice' parts of ASP.NET MVC allowing you to use the awesome abilities of Durandal and Knockout with almost no downfalls.

Live demo using Durandal.js
In a nutshell it provides a bunch of features which makes doing Durandal/Knockout development just as easy as ASP.NET MVC. (You simply provide a C# type that your JavaScript model is based off of for most of the features.) You only have to write JavaScript and un-compiled markup for complicated cases which is unavoidable and no different than MVC! (Except in MVC your code would also likely end up would also be a big jQuery mess which is why you are using Durandal/Knockout in the first place!)
Features:
Painlessly generate Knockout syntax with strongly typed, fluent, lambda expression helpers similar to ASP.NET MVC
Rich intellisense and compiler support for syntax generation
Fluent syntax makes it a breeze to create custom helpers or extend whats built in
OSS alternative to ASP.NET MVC helpers: feel free to add optional features that everyone in the community can use
Painlessly provides validation based on .NET types and DataAnnotations in a few lines of code for all current/future application types and changes
Client side JavaScript object factory (based on C# types) to create new items in for example, a list, with zero headaches or server traffic
Example without FluentKnockoutHelpers
<div class="control-group">
<label for="FirstName" class="control-label">
First Name
</label>
<div class="controls">
<input type="text" data-bind="value: person.FirstName" id="FirstName" />
</div>
</div>
<div class="control-group">
<label for="LastName" class="control-label">
Last Name
</label>
<div class="controls">
<input type="text" data-bind="value: person.LastName" id="LastName" />
</div>
</div>
<h2>
Hello,
<!-- ko text: person.FirstName --><!-- /ko -->
<!-- ko text: person.LastName --><!-- /ko -->
</h2>
Provide FluentKnockoutHelpers with a .NET type and you can do this in style with Intellisense and a compiler in Razor / CSHTML
#{
var person = this.KnockoutHelperForType<Person>("person", true);
}
<div class="control-group">
#person.LabelFor(x => x.FirstName).Class("control-label")
<div class="controls">
#person.BoundTextBoxFor(x => x.FirstName)
</div>
</div>
<div class="control-group">
#person.LabelFor(x => x.LastName).Class("control-label")
<div class="controls">
#person.BoundTextBoxFor(x => x.LastName)
</div>
</div>
<h2>
Hello,
#person.BoundTextFor(x => x.FirstName)
#person.BoundTextFor(x => x.LastName)
</h2>
Take a look at the Source or Live Demo for an exhaustive overview of FluentKnockoutHelper's features in a non-trivial Durandal.js application.
Yes, you can absolutely use cshtml files with Durandal and take advantage of Razor on the server. I assume that also means you want MVC, so you can do that too and use its routing.
If you don;t want the routing then you can set the webpages.Enabled in the web.config, as the other comments suggest.
<add key="webpages:Enabled" value="true" />
I don't recommend that you use .cshtml files as views directly. You're better off placing the .cshtml files behind a controller.
For example, take the HotTowel sample, edit /App/main.js, and replace the function definition with the following:
define(['durandal/app',
'durandal/viewLocator',
'durandal/system',
'durandal/plugins/router',
'durandal/viewEngine',
'services/logger'],
function (app, viewLocator, system, router, viewEngine, logger) {
Note that we added a reference to the Durandal viewEngine. Then we need to replace
viewLocator.useConvention();
with
viewLocator.useConvention('viewmodels', '../../dynamic');
viewEngine.viewExtension = '/';
The first argument to viewLocation.useConvention sets the /Apps/viewmodels/ directory as the location for the view models js files, but for the view location, uses the URL http://example.com/dynamic/, with an extension of '/'. So that if Durandal is looking for the view named 'shell', it will reference http://example.com/dynamic/shell/ (this is because the view directory is mapped relative to the viewmodels directory, hence /App/viewmodels/../../dynamic will give you simply /dynamic).
By convention, this previous URL (http://example.com/dynamic/shell/) will be mapped to the controller DynamicController, and the action "Shell".
After this, you simply add a controller - DynamicController.cs, like this:
// will render dynamic views for Durandal
public class DynamicController : Controller
{
public ActionResult Shell()
{
return View();
}
public ActionResult Home()
{
return View();
}
public ActionResult Nav()
{
return View();
}
public ActionResult Details()
{
return View();
}
public ActionResult Sessions()
{
return View();
}
public ActionResult Footer()
{
return View();
}
}
Create .cshtml files for each of the above actions. This way you get to use controllers, server side IoC et al to generate dynamic views for your SPA.
DurandaljS is a client framework which forms mainly a solid base for single-page apps (SPA).
I assume you are using asp.net web API as your server technology. In that case, you can determine the user's role inside your API controller and based on that return data to the client. On the client you can use Knockout "if" binding in order to show / hide certain areas of your page.
What you perhaps can do is placing this code in the Index.cshtml.
Following link shows how to customize moduleid to viewid mapping
http://durandaljs.com/documentation/View-Location/
by convention durandal tries to find view url in following steps
1) Checke whether object has getView() function which returns either dom or a string ( url for the view)
2) If object does not have getView function then checks whether object has viewUrl property
3) If above two steps fails to produce url or a DOM view drundal falls to default convention
which maps moduleid xyz.js to view xyz.html using view url ( path of Views folder ) defined in main.js
so for moduleid xyz.js path of the view will be views/xyz.html
you can overwrite this default mapping behavior by overwriting convertModuleIdToViewId function.
So there are many ways you can customize your view url for specific model (.js object)
I made an extension to Durandal which gives you the ability to place an applicationContent div in your cshtml file together with the applicationHost div. In applicationContent you can now use both ASP .Net MVC syntax together with knockout bindings.
Only thing I did was put some extra code in the viewLocator.js file which looks for an applicationContent div:
locateViewForObject: function(obj, area, elementsToSearch) {
var view;
if (obj.getView) {
view = obj.getView();
if (view) {
return this.locateView(view, area, elementsToSearch);
}
}
if (obj.viewUrl) {
return this.locateView(obj.viewUrl, area, elementsToSearch);
}
view = document.getElementById('applicationContent');
if (view) {
return this.locateView(view, area, elementsToSearch);
}
var id = system.getModuleId(obj);
if (id) {
return this.locateView(this.convertModuleIdToViewId(id), area, elementsToSearch);
}
return this.locateView(this.determineFallbackViewId(obj), area, elementsToSearch);
},
Your original cshtml file can now do something like this:
<div class="row underheader" id="applicationContent">
<div class="small-5 columns">
<div class="contentbox">
#using (Html.BeginForm("Generate", "Barcode", FormMethod.Post, Attributes.Create()
.With("data-bind", "submit: generateBarcodes")))
{
<div class="row formrow">
<label for="aantalBijlagen">#Translations.Label_AantalBijlagen</label>
</div>
<div class="row">
<select name="aantalBijlagen" class="small-6 columns">
<option>0</option>
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
</select>
</div>
<div class="row">
<button class="button right" type="submit" id="loginbutton"><span class="glyphicon glyphicon-cog"></span> #Translations.Action_Generate</button>
</div>
}
</div>
</div>
<div class="small-7 columns" data-bind="if: hasPdfUrl">
<div class="contentbox lastcontent">
<iframe data-bind="attr: {src: pdf_url}"></iframe>
</div>
</div>
You can find my fork of the durandal project here and a small blogpost of what and how I did this here.
I'm not very familiar with DurandalJS but because it's a client-side system, it should make no difference what technology is used on the server to generate the HTML markup. So if you use Razor CSHTML files to generate the HTML on the server, DurandalJS should work just fine with it.
If you're getting a particular error then please share that error, but I can't think of any reason why it wouldn't work.
