How would I render an async script tag in hiccup?
<script src="demo_async.js" async></script>
I think you should just code it as
(use 'hiccup.core)
(html
[:script {:src "demo_async.js" :async "async"} ] )
=> <script src="demo_async.js" async="async" ></script>

Iam trying to use Graphos with my Django html template to grab data from csv, and display a graph. I tried from the documentation https://pypi.org/project/django-graphos/, but the template isnt showing anything.
In my views i did this
from graphos.sources.csv_file import CSVDataSource
def graphos_chart(request):
csv_file = open("order_dashboard/Book1.csv")
data_source = CSVDataSource(csv_file)
return render(request, 'order_dashboard/home.html', {'chart': data_source})
template
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
</script>
{{ data_source|safe }}
Book1.csv
,January,February,March,April,May,June,July
Temperature,7,7,10,15,20,23,26
Precipitation,8.1,14.9,41.0,31.4,42.6,57.5,36.0
Something is missing in above method?
Or please suggest any alternate Graph plotting library to look for.
I have my app using gmaps4rails working for a while after Google moved to GIT.
Here is what I am using in the application.htm.erb
<script src="https://maps.google.com/maps/api/js?v=3.23&libraries=geometry;&key=AIzaSyAncOJnAgKEjrv2PY__Z0gYy3zJyTznUQ0" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/googlemaps/js-rich-marker/gh-pages/src/richmarker-compiled.js" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/googlemaps/v3-utility-library/master/infobox/src/infobox_packed.js" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/googlemaps/v3-utility-library/master/markerclustererplus/src/markerclusterer_packed.js" type="text/javascript"></script>
And in the Gemfile I have these lines
gem 'geocoder'
gem 'gmaps4rails'
gem 'underscore-rails'
In the application.js I have this line
//= require gmaps/google
Here is the page supposed to render the map.
<div class="row-fluid">
<div id="map" style='width: 100%; height: 500px; border: 1px solid black;'></div>
</div>
<script type="text/javascript">
buildMap (<%=raw #hash.to_json %>);
</script>
And the associated coffee script is
class RichMarkerBuilder extends Gmaps.Google.Builders.Marker #inherit from builtin builder
#override create_marker method
create_marker: ->
options = _.extend #marker_options(), #rich_marker_options()
#serviceObject = new RichMarker options #assign marker to #serviceObject
rich_marker_options: ->
marker = document.createElement("div")
marker.setAttribute 'class', 'marker_container'
marker.innerHTML = #args.title
_.extend(#marker_options(), { content: marker })
infobox: (boxText)->
content: boxText
pixelOffset: new google.maps.Size(-140, 0)
boxStyle:
width: "400px"
# override method
create_infowindow: ->
return null unless _.isString #args.infowindow
boxText = document.createElement("div")
boxText.setAttribute("class", 'marker_info_box') #to customize
boxText.innerHTML = #args.infowindow
#infowindow = new InfoBox(#infobox(boxText))
#buildMap = (markers)->
handler = Gmaps.build 'Google', { builders: { Marker: RichMarkerBuilder} } #dependency injection
#then standard use
handler.buildMap { provider: {}, internal: {id: 'map'} }, ->
markers = handler.addMarkers(markers)
handler.bounds.extendWith(markers)
handler.fitMapToBounds()
None of this code was recently changed (in the last week or so).
I only executed a bundle update today that upgraded the gems jbuilder from 2.4.1 to 2.5.0 and autoprefixer from 6.3.6.1 to 6.3.6.2.
The app was working having the map rendered until now when the map is not shown anymore.
I reverted these two gems to the previous versions but still no map rendered.
Don't know how to make it working again?
I just changed the order of the scripts to be loaded and now the map is rendered again, here is the code:
<script src="//maps.google.com/maps/api/js?v=3.23&libraries=geometry;&key=AIzaSyAncOJnAgKEjrv2PY__Z0gYy3zJyTznUQ0" type="text/javascript"></script>
<script src="//cdn.rawgit.com/googlemaps/js-rich-marker/gh-pages/src/richmarker-compiled.js" type="text/javascript"></script>
<script src="//cdn.rawgit.com/googlemaps/v3-utility-library/master/infobox/src/infobox_packed.js" type="text/javascript"></script>
<script src="//cdn.rawgit.com/googlemaps/js-marker-clusterer/gh-pages/src/markerclusterer.js" type="text/javascript"></script>
<script src="//cdn.rawgit.com/googlemaps/v3-utility-library/master/markerclustererplus/src/markerclusterer_packed.js" type="text/javascript"></script>
Problem solved.
I have this html snippet. I want parse that snippet and emit html without javascript tags
<html>
<body>
<div class="content">lorem ipsum</div>
<script src="/js/jquery.js" type="text/javascript"></script>
<script src="/js/bootstrap.min.js" type="text/javascript"></script>
</body>
</html>
become this
<html>
<body>
<div class="content">lorem ipsum</div>
</body>
</html>
I couldn't found enlive helper function to remove tags.
I have found the solution thanks for the example. So I write this code and the js disappeared
(html/deftemplate template-about "../resources/public/build/about/index.html"
[]
[:script] (fn js-clear [& args] nil)
)
My usual approach when I need to conditionally remove some tags of the rendered page is to use a nil returning function.
For instance
(html/defsnippet upgrade-plan "page_templates/upgrade-plan.html" [:#upgradePlanSection]
[pending-invoice ... ]
...
[:#delayedPlanWarning] #(when pending-invoice
(html/at %
[:#delayedPlanWarning] (html/remove-attr :style)
[:.messagesText] (html/html-content (tower/t :plans/pending-invoice
(:id pending-invoice)))))
...
In that particular case if pending-invoice is nil the delayedPlanWarning element is removed from the rendered html since the function returns nil.
If you don't mind the extra parsing and emitting, the following would do nicely:
(def orig (html-resource (java.io.StringReader. "<html>
<body>
<div class=\"content\">lorem ipsum</div>
<script src=\"/js/jquery.js\" type=\"text/javascript\"></script>
<script src=\"/js/bootstrap.min.js\" type=\"text/javascript\"></script>
</body>
</html>")))
(def stripped (transform orig [(keyword "script")] (substitute "")))
(apply str (emit* stripped))
When removing whole tags, you only need to use nil as your transformation.
(deftemplate tester1
(java.io.StringReader. "<html><body><div class=\"content\">...")
[]
[:script] nil)
(template1)
In your case, you would replace the StringReader with the resource you are using.
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}
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>
