Jade - Using Block inside script tag - templates

Hi there I'm trying using Jade's blocks and extends for a node.js project, and the ideia is to have something like this:
layout.jade:
head
script
$(document).ready(function() {
block js_doc_ready
//here goes the doc ready
});
index.jade:
block js_doc_ready
alert('hello!');
alert('one more js line code');
alert('end my js doc ready for this view');
This would give me a index.html like this:
...
<head>
<script type="text/javascript">
$(document).ready(function() {
alert('hello!');
alert('one more js line code');
alert('end my js doc ready for this view');
});
</script>
</head>
...
But when I see the result, the 'block js_doc_ready' is not considered a Jade block.
Also, even if it was considered a block, the "alert('hello!);' wouldn't be considered a, but a Jade tag.
This is something that I used to do in django template, but in jade with all this tags, and no liberty to do pure html I still find it a little too strange to make this things.

Jade do not translate what's inside 'style' and 'script' code. Never.
What will work is based on an answer I gave to another question (using a style element but that's basically the same).
!!!
head
title Hello jade
| <script type='text/javascript'>
| $(document).ready(function() {
block js_doc_ready
| });
| </script>
This way : jade will include the HTML 'script' tags and $.ready lines but will also include your block.

Can't get to add JS to front via $this->load->view

I'm developing a module for OpenCart 3.x and I'm trying to insert some JavaScript code into website's front via $this->load->view() method but cannot get it to work, as the JS code doesn't appear in the DOM.
Here's an excerpt of my code:
/catalog/controller/extension/module/mymodule.php
class ControllerExtensionModuleMyModule extends Controller {
public function index() {
$this->load->language('extension/module/mymodule');
$this->load->model('checkout/order');
$this->load->model('setting/setting');
$this->load->model('design/layout');
$this->load->model('catalog/category');
$this->load->model('catalog/manufacturer');
$this->load->model('catalog/product');
$this->load->model('catalog/information');
$data['js_output'] = "Some JS output";
return $this->load->view('extension/module/mymodule', $data);
}
}
catalog/view/theme/default/template/extension/module/mymodule.twig
<script type="text/javascript">
console.log('This is working!");
</script>
Am I missing something?
Add an external javascript file via controller like this:
$this->document->addScript('catalog/view/javascript/my-external-script.js');
But if it's a block of javascript code, you don't need to edit controller file, just add it to your view file (twig or tpl):
<script type="text/javascript">
console.log("This is working!");
</script>
Finally you may need to clear caches (vqmod, ocmod, twig etc ...).
EDIT
If you want to prepare your javascript code in the controller, follow this:
controller
$data['js_output'] =
'<script type="text/javascript">
console.log("This is working!");
</script>';
Twig
{{ js_output }}
I have finally fixed the issue. It was a problem with the install() method not correctly inserting and loading the design/layout ($this->model_design_layout->getLayouts()).
If your module needs to insert a layout into the layout_module table, make sure you have the correct layout_id, code(which must be your module name), position (i.e: 'content_bottom') and sort_order(which often times is > 90).

Play Framework 1.2.5 - adding to <script> tag

In my play framework app, I have a main.html, which at the very bottom includes this javascript tag:
<script>
$(function() {
// add js here
#{scripts /}
});
</script>
Now I would like to be able to add arbitrary javascript from other templates, which is then collected and added to the function body, so for example in view1.html, I'd like to add the function doCharts() to be called on jQuery's DOMReady:
#{append: 'scripts'}
doCharts();
#{/append}
This should then produce this output:
<script>
$(function() {
// add js here
doCharts();
});
</script>
Is this possible?
Yes this is possible
In your main file, after your script tag put
#{get 'moreScripts' /}
and in your other html files use
#{set 'moreScripts'}
<script type="text/javascript">
// put your script here
</script>
#{/set}
if you want to put another script in the same page you can put a get into the set like this
#{set 'moreScripts'}
#{get 'moreScripts' /}
<script type="text/javascript">
// put your script here
</script>
#{/set}

Getting the content rendered inside a #each ember template helper, without the #each content binding

/START description of why
I'm doing a 'load more' type of interaction: user gets at bottom of a page, I load more content.
As I'm using a plugin that formats content in a 'pinterest-style' (masonry), I need to take the output of a rest call, formatted using an ember view, and i'm doing something like:
<div id="list">
</div>
<div id="hidden" style="display:none">
{{#each item in App.itemsController}}
test {{item.id}}
<br />
{{/each}}
</div>
What I want to do is, load the content in the hidden div, and then pass its HTML generated content to the plugin to process in my formatted list view.
If I just copy the #hidden content, the Ember scripts get in, and on subsequent 'load more', content is inserted in the #list, in addition of going in the #hidden div.
That's because I copied the entire handlebars.
So I get rid of the container tag, the one I supposed was wrapping the controller content binding, but even when stripping it from the content I pass to #list, the #list still auto-updates when a 'load more' is called.
I know that's a dirty hackish thing, but in order to improve performance in the client I must take a similar route.
/END description of why
//ACTUAL QUESTION ;)
Given this background, the question is, stripping the container metamorph script tags (like the ones here below), and just take the content inside them, shouldn't get rid of the auto-updating content functionality?
<script id="metamorph-X-start" type="text/x-placeholder"></script>
//ALL THE CONTENT
<script id="metamorph-X-end" type="text/x-placeholder"></script>
Inside those, I just have the actual content generated, like:
<script id="metamorph-9-start" type="text/x-placeholder"></script>
test <script id="metamorph-59-start" type="text/x-placeholder"></script>2873<script id="metamorph-59-end" type="text/x-placeholder"></script>
<br>
<script id="metamorph-9-end" type="text/x-placeholder"></script>
<script id="metamorph-10-start" type="text/x-placeholder"></script>
test <script id="metamorph-60-start" type="text/x-placeholder"></script>2872<script id="metamorph-60-end" type="text/x-placeholder"></script>
<br>
<script id="metamorph-10-end" type="text/x-placeholder"></script>
The alternative is programmatically render the template inside a variable and process that, which is surely a better way of doing this, but I just wonder how the #each binding works internally as I thought the metamorph was doing that.
Have you looked into using a CollectionView and calling the plugin through the didInsertElement callback?
e.g.
MyList = Ember.CollectionView.extend({
itemViewClass: 'App.ListItem',
didInsertElement: function(){
view.$().jqueryPlugin({ ... })
}
})

Best method to use external templates with knockout

I have built a html page with some internal templates. See url jsfiddle:
http://jsfiddle.net/hoven002/jQTDH/
What is the best method to make the templates external and how?
Regards,
Kenneth
The best method, in my opinion, is to use this plugin: https://github.com/ifandelse/Knockout.js-External-Template-Engine.
It enables a new template engine that will pull templates from external files. It has some configuration options as well to determine where the templates are pulled from.
I've written a function that loads templates, without any dependency but jQuery. You must mark each <script> tags you want to be dynamically loaded with the attribute data-template-src and put there the path of your HTML file. Following is the code and an example.
Warning: since it uses AJAX to load templates, it needs an HTTP server (it won't work locally with file:// protocol)
/main.js
// Loads all the templates defined with the tag data-template-src.
// Returns a promise that fulfills when all the loads are done.
function loadTemplates() {
var templateLoads = [];
$('[data-template-src]').each(function () {
var templateElement = $(this);
var templateUrl = templateElement.attr('data-template-src');
// Load the template into the element and push the promise to do that into the templateLoads array
templateLoads.push(
$.get(templateUrl)
.done(function (data) {
templateElement.html(data);
})
);
});
return $.when.apply($, templateLoads);
}
// When all templates are loaded, apply bindings
loadTemplates().done(function () {
ko.applyBindings({}, document.getElementById("htmlDoc"));
});
/index.html
<html id="htmlDoc">
<body>
<div data-bind="template: { name: 'exampleTemplate' }"></div>
<script type="text/html" id="exampleTemplate" data-template-src="/assets/exampleTemplate.html"></script>
<script src="/jquery.js"></script>
<script src="/knockout.js"></script>
<script src="/main.js"></script>
</body>
</html>
/assets/exampleTemplate.html
<h1>Hello world</h1>
<div data-bind="template: { name: 'exampleSubTemplate' }"></div>
/assets/exampleSubTemplate.html

How to configure Mathjax in Python Django

I would like to know how to configure Mathjax in Django in a Q&A system where Questions and Answers will be based on LaTeX format.
I have tried to add:
<script type="text/javascript"
src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
into the html template where the questions and answers will be displayed to no avail.
Thanks.
If the page's content is dynamically created, you will need to call MathJax after the content has been loaded. See the documentation for details. The main idea is that you have to include
MathJax.Hub.Queue(["Typeset",MathJax.Hub]);
in the javascript that is executed after the content is in place.
fOR Dynamic content here's is the working solution. I used AsciiMath Input as the input format in mathjax that incorporates ASCIIMathML.
In the base.html add the following scripts:
<script>
MathJax = {
loader: {load: ['input/asciimath', 'output/chtml']}
}
</script>
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/startup.js"></script>
<script type="text/javascript" id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/tex-chtml.js">
and remember to enclose the dynamic text by back-ticks”, i.e., `...` So in the django-admin you can simply enter sqrt(50) as ` sqrt(50) ` or ` x^2 ` and the dynamic content which is passed from view to the template, in the template you surround {{e1}} by back-ticks
` {{ e1 }} `
instead of
{{ e1 }} where e1 is the dynamic content. So if e1 which was earlier displayed in plain text as 2*sqrt(2) will now be displyed as 2√2.
For more details: http://docs.mathjax.org/en/latest/input/asciimath.html#asciimath-support
see https://docs.mathjax.org/en/latest/web/configuration.html. For the demo indicated here to work you should also add ['\(', '\)'] to inlineMath:
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']]
},
svg: {
fontCache: 'global'
}
};
</script>
<script type="text/javascript" id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax#3/es5/tex-svg.js">
</script>
