I have a JSON file that has some simple fields and content. I want to make a 2sxc app that simply lists out the content of the JSON file using C# Razor. (Ultimately this json file will be hosted elsewhere).
Ideally, the content will be rendered as simple HTML in the page that I can see when I click view source in the browser so I know it's SEO friendly.
Is this possible? What kind of code would I need to do this?
I was able to figure it out using this example: https://2sxc.org/dnn-tutorials/en/razor/json/home
So my code looked something like this:
#inherits ToSic.Sxc.Dnn.RazorComponent
#inherits Custom.Hybrid.Razor12
#{
var someJson = System.IO.File.ReadAllText(App.PhysicalPath + "/json/UseCases.json");
var thing = AsDynamic(someJson);
}
#foreach(var useCase in thing.UseCases) {
#useCase.URLPart
<h3>Name: #useCase.Name</h3>
<h4>#useCase.Domain</h4>
<p>#useCase.ShortDescription</p>
#Html.Raw(useCase.Highlights)
}

I want to show PDFs in my angular application. It should be possible to show multiple pages at once and to search inside the PDF.
I tried angularjs-pdf to do so, but it lacks these features. Is there a angular wrapper for pdf.js that can do this? Or can somebody get me startet on how to implement pdf.js in my angular application without a wrapper?
Assuming this statement:
"I want to show PDFs in my angular application"
Anyone searching for this, could ought to check out ng2-pdf-viewer, for more information on this module, can check this out ng2-pdf-viewer PdfShowcase
Basically, this module could somewhat allow one to display more than one PDF in a single screen.
app.component.ts
// Declare the pdf as an empty array
pdfs = [];
// Assuming requesting PDFs from server through MVC style
getPdfs(){
this.getPdfService.getPdfs().subscribe(response => {
response.body.forEach((value, index) => {
this.pdfs.push({
id: index,
obj: window.URL.createObjectURL(value);
});
});
});
}
app.component.html
<div *ngFor="let pdf of pdfs, index as i;">
<div *ngIf="pdf[i]">
<pdf-viewer
[rotation]="0"
[original-size]="true"
[show-all]="true"
[fit-to-page]="true"
[zoom]="0"
[zoom-scale]="'page-width'"
[stick-to-page]="true"
[render-text]="false"
[external-link-target]="'blank'"
[autoresize]="true"
[show-borders]="true"
[src]="pdf.obj"
(after-load-complete)="onPdfComplete($event)"
(error)="onPdfError($event)"
style="width: 100%; height: 800px;">
</pdf-viewer>
</div>
</div>
If this library is not suitable for your use case, you may try with other libraries which uses iframe or similar strategy. Refer here is a useful source worth checking it out.
I know I'm a little bit late for this post but thought of posting here might help some folks who is looking for the same thing. Hope it helps.
From ng2-pdf viewer page, it recommends your desire "angular wrapper for pdf.js", There are a ton of built in functionality Mozilla's viewer supports; such as print, download, bookmark, fullscreen, open file, zoom, search,......
If you need to display multiple PDF files simultaneously and if you don't mind using iFrames, I recommend ng2-pdfjs-viewer. https://www.npmjs.com/package/ng2-pdfjs-viewer
I'm trying to use react.js in Hugo. I know Go template variables are accessible in HTML file.
My question is how to access them in javascript. or is there a workaround?
thanks in advance.
UPDATE：
currently my workaround is to use meta tags in HTML and load Go template variables like this:
<meta name="title" content={{.Title}} />
and then in javascript,
function getMetaTitle() {
var metas = document.getElementsByTagName('meta');
for (i=0; i<metas.length; i++) {
if (metas[i].getAttribute("name") == "title") {
return metas[i].getAttribute("content");
}
}
return "failed to access...";
}
var metaTitle = getMetaTitle();
but this way is inconvenient when the number of meta tags growing, is there a more concise way to do this?
I doubt Hugo and React is a good pair but that's off topic and I might be wrong about that. You are asking, how to get Hugo variables into website's JavaScript. My answer:
Hugo is static website engine, so it only converts templates and markup documents (with your content) into HTML files. Now, when you upload your files onto your server, your JS cannot see anything Hugo — only your files.
The question becomes, how to transfer Hugo variables into some files of your website.
As you suggested, it's best to write variables into your HTML (or JSON) using Hugo, then read them by JS. If it's small amount, use attributes or tags. If there's a lot and it doesn't differ per-page, use a separate JSON file.
For example, personally I have a multilingual site which a) requires different language titles to appear dynamically via JS; b) uses JS which queries different Lunr.js search indexes in JSON format.
For both I use data-<name> attributes:
<section class="section-search" data-index="{{ .Site.BaseURL }}searchIndex.json" id="section-search">
<input type="search" id="search-input" placeholder="{{ ( index $.Site.Data.translations $.Site.Params.locale ).dataloading }}" data-loaded="{{ ( index $.Site.Data.translations $.Site.Params.locale ).dataloaded }}">
<!-- search button goes here -->
</section>
For example, on English templates (rendered into /public/), data-loaded attribute would be in English, but for Lithuanian templates (rendered into /public/lt/), data-loaded attribute would be in Lithuanian.
I wouldn't worry about "growing meta tags", but you could maybe write variables into a JSON file and then read it in JS if you are concerned about HTML bloat?
I'm building custom JSON first as HTML, then minifying/renaming it into JSON when building indexes for Hugo Lunr search as per this recipe. Instead of "baking in" the content with range as in mentioned recipe, you could simply list all the variables.
By the way, I'm using npm scripts as a build runner (instead of Grunt/Gulp) so I use json-minify:
"index:prepare": "json-minify public/json/index.html > public/site-index.json",
You could "bake" JSON files with any content (including Hugo template variables) via Hugo this way. Hope it helps.
You can specify a custom output format for Javascript within your config.toml so that Hugo then treats those particular formats and file extensions like it's content files where it replaces the template variables with adequate values.
So, an entry such as below in your config.toml will treat javascript files as one of the media type it needs to consider for its custom output formats:
[mediaTypes]
[mediaTypes."application/javascript"]
suffix = "js"
You can read more about it here
You can, of course, inline your JS in your layout files, but that is probably not what you want.
There have been some discussions about improvements in this area on the Hugo discussion site, but nothing concrete yet.
I'm trying to figure out how to link an html picture element back to the database entry that was originally used to generate the picture link.
I am using Meteor:
- I have a database that contains photosets data from Flickr API
- In the HTML, I have a handlebar "each" script that iterates through each photoset in the database and then uses this info to generate the html for the photoset cover picture links.
- When the html renders, the photoset cover pictures are downloaded from Flickr and displayed to the screen.
I would like to be able to click on the photoset cover picture and then automatically generate the links to the pictures in the photoset. But I don't understand how to dynamically link the html picture elements back to their respective database entries that were originally used for generating the picture links. I need to be able to find the original database entries so that I can load the info needed for generation of subsequent links.
As a newb to all of this I'm not really sure where to start looking or what to try. I've wondered about creating an object with custom key pairs to 'memorise' the identity of each photoset picture. Is this the way to go, or is there an easier way that I am overlooking?
Thanks.
Say you have your pictures being put out this way:
Template.mytemplate.helpers({
picture:function() {
return pictures.find()
}
});
You can also do this instead, which is pretty much the same thing:
Template.mytemplate.picture = function() {
return pictures.find();
}
With the html
<template name="pictures">
{{#each picture}}
<img src="{{src}}" class="pictureselector"/>
{{/each}}
</template>
You can use events which can get data from that particular picture document/record
Template.mytemplate.events({
'click .pictureselector':function(event,template) {
console.log(this._id); //Should give you the `_id` of the picture that was clicked
}
});
this is the data context of the element that was clicked & generate the link you want using the data inside this.
Be careful if you use something with a callback inside the click like Meteor.call, you will have to relay the message down via var self = this otherwise the context of this would become the one of Meteor.call
Implementing EasyCaptions on my WordPress blog and I’ve hit a brick wall. Any help would be appreciated. I’m using SWFobject to embed videos. I’ve pasted this code: http://pastebin.com/0ZMSr0Bz into my header.php and this embed code in my posts:
<video id="video-html5" width="480" height="320" controls="controls"
source src="[url to video]" />
</video>
The problem is the implementation only works for the video defined here:
var flashvars = { file:'[video url]', ...
All other videos embeds do not work. I've tried using a playlist but that did not solve the problem. How do I solve this? Do I need additional JS or PHP code to add to the file parameter?
[edited post]
I just re-read your question and looked at the pastebin. The video URL you're using is an HTML file: http://vidbull.com/embed-iqkhawkkx1rn-640x318.html. You can't load an HTML file as a video.
Try it again using a proper video URL (MP4, F4V, OGG, etc).
-- UPDATED based on comment from OP --
The issue is that you're hard-coding the video URL in your WordPress header. What you'll need to do is use a variable instead. I suggest using WordPress' "shortcode" API, which will enable you to pass variables via a custom shortcode.
Define your shortcode in WordPress, something like:
//[easycaptions]
function embed_easycaptions( $atts ){
//your custom PHP code here, using the passed $atts
}
add_shortcode( 'easycaptions', 'embed_easycaptions' );
Then when authoring your WordPress blog post, you add the custom shortcode where desired, such as
[easycaptions url='http://localhost/wordpress1/wp-content/uploads/2012/10/Sheldon-in-a-Dress.mp4']
Check out the Shortcode API page for instructions and examples. It's a pretty powerful system.
The solution lies in NOT hard-cording the video url in the header.php. Here is what worked to solve this. I first created a custom field in wordpress, named it thinema, and then set the value of the custom field to be the embedded video url in the post. Then edited this code into my header.php
flashvars = { file: '<?php echo get_post_meta(get_the_ID(), thinema, true); ?>'...
I've updated the code in pastebin. Hope this is of use to someone! You can view the implementation here.
I've managed to build a page that will display data from the database dynamically. However, this code which is saved in the database:
<p>This is the content for the radio page.</p>
Displays like this:
<p>This is the content for the radio page.</p>
The HTML tags aren't rendered. I understand that Symfony (for security purposes) renders any HTML code like this for security reasons. I want Symfony (obviously) to render these HTML tags. How can I achieve this just for this purpose only, so that Symfony still sanitises any HTML tag that is saved to the database elsewhere on the site?
For your information as well, this is the code that I am using to pull the data from the database:
public function mainpageAction($slug)
{
$content = $this->getDoctrine()
->getRepository('SiteMainBundle:Content')
->find($slug);
if (!$content) {
throw $this->createNotFoundException('No product found for slug '.$slug);
}
return $this->render('SiteMainBundle:Default:page.html.twig', array('content' => $content, 'slug' => $slug));
}
Also, just so I can learn more about Symfony, is the rendering of the HTML tags just the sole job of PHP or could it be rendered properly using Twig?
Many thanks!
If you want to do that, you need to use the raw filter in the twig template. Like described in the twig documentation, the raw filter marks the value as safe which means that in an environment with automatic escaping enabled this variable will not be escaped if raw is the last filter applied to it.
In your case, it's : {{ content | raw }}
