angular-perfect-scrollbar | update, scroll to bottom, or alternative - angularjs

I just installed angular-perfect-scrollbar.
I used the jQuery perfect-scrollbar Plugin but since angular it was thrown out.
Question:
is there a way to update the angular-perfect-scrollbar like $('#container').perfectScrollbar('update'); in jQuery ?
how can I scroll to bottom of container (on content change) with that angular plugin?
If thats not possible with this angular plugin are there alternatives that includes the features above ?

as I tested, you need to add <include-padding='true'> to html tag then it could scroll to bottom(in fact this will change the scroller length, therefore)
it looks like
<perfect-scrollbar include-padding='true'>
<..your stuff..>
</perfect-scrollbar>
cheers

OnsenUI loads page in text, via a splitter

I have previously created a web app, and now I would like to integrate it with OnsenUI to enable my app to be used on all mobile devices as well as the web.
I am using a splitter in a toolbar which will be the header of all pages, and it will redirect the user to other pages when they click an item in it. Clicking the home item successfully redirects to the home page (index, which is already loaded correctly). However, clicking any of the other items in the splitter redirects me to the requested page, but shows the content of the file in text format instead of actually rendering the page. It looks like the following, except it's all jumbled together with no spaces:
searchForTrainer.jade:
//-ons-template(id='searchForTrainer.jade')
ons-page(ng-controller='SearchController' ng-init='showme = false; getAllTrainers();')
ons-toolbar
.left
ons-toolbar-button(ng-click='mySplitter.left.open()')
ons-icon(icon='md-menu')
.center
| Search Trainer
// ***** I cut off the rest of the file for simplicity
// ***** I should still be able to see the toolbar if the page loads correctly
Here is the content of index.jade:

Has anyone successfully built an Onsen app using Jade?
UPDATE
When I leave the code in html instead of jade, everything works correctly. When I convert it back to jade it shows up as text again.
UPDATE 2
Using Solution 1 from the selected answer, I realized and solved my problem with the guidance from the selected answer on my other post:
Answer
By the looks of it you seem to be using Jade on the server side.
To solve the problem I see a couple possible solutions.
Solution 1:
Make sure that whatever Onsen UI is receiving is pure HTML. You're free to use Jade, but as it stands Onsen does not have Jade bundled inside, so there is no way for it to support it out of the box. However as long as Onsen sees only html it should be fine.
The reason why the ons-template(id='index.jade') works initially is actually because when you serve the page you are actually serving actual html, so when onsen starts the contents of that template are actually pure html.
In searchForTrainer.jade it seems that you are giving it raw jade, which it does not know how to handle. You can handle this on the server side, making sure that the request for the searchForTrainer returns html. Returning jade.renderFile('searchForTrainer.jade') from the server instead of the jade file itself should solve the issue.
Solution 2:
As you noticed as long the contents are inside the initial page everything will be fine. So you could just put all your ons-templates inside the initial page.
If you want to retain your current file structure you can just do
include searchForTrainer.jade
while having an ons-template tag in the file itself. That way in the end the result will be a page with the template already converted into html.
Solution 3:
The final option is to give the raw jade files, but help Onsen understand Jade, so that it can use them properly. To do that you need to include jade.js and modify Onsen UI so that it uses it.
However since Onsen does not currently provide an official API for switching template engines whatever hack we use now might break in the future. It's possible that in the near future a feature like that may be implemented, but in order to do it now we need to wrap some of onsen's internal functions.
Here's a simple example to do it.
module.run(function($onsen) {
var old = $onsen.normalizePageHTML;
ons._internal.normalizePageHTML = $onsen.normalizePageHTML = function(html) {
return old(jade.render(html, {}));
};
});
And here's also a working Demo showing this solution in action.
Note: that demo actually checks for a comment // jade at the beginning just to be safe.
Which solution to choose?
Solution 1 - I think this makes most sense as it retains a clear separation of concerns. If you want to change the templating engine it should be handled only in one place. Onsen does not need to know what you're using on the server as long as it gets what it wants.
Solution 2 - Not the best way to solve the problem, but it may be the easiest to use if you just want things to work. One minus is that with it you would load all the templates at the beginning, which may not be very good.
Solution 3 - While this solution can work I would suggest avoiding it as handling jade on the frontend would result in poor performance. It's could be an option if you actually decide not to rely on the server.

ng-srcset images initially not displaying in IE11 intermittently

The page loads without any of the images displaying on IE11 only, but refreshes them accordingly when we resize the browser intermittently (1/3 loads). We cannot replicate this with any of the other browsers. srcset works fine by itself with static content.
Here is a Plunker example of it not working in IE11.
Or quick and easy, the actual img html we're using:
<img data-ng-srcset="{{::image.url}}, {{::image.url2x}}" alt="{{::image.name}}"/>
The images or surrounding divs do not have any transitions, shadows or opacity applied.
The html renders fine with angular passing over and rewriting the srcset attribute correctly. The images just do not appear, only the alt tag. Wondering if this could be a call stack issue due to the intermittence of it, maybe a race condition with Picturefill loading before angular finishes a digest or something.
Cheers in advance!
A work around if you use PictureFill in a loop and in a specific case (not on all images of your application), is calling a function that launch PictureFill directly from HTML, after last item loaded (this is not the best practice but fix the IE11 problem) :
<picture><!-- Your image --></picture>
<span ng-if="$last">
{{ controllerAlias.launchPictureFill() }}
</span>
Came across this as a solution: http://tech.endeepak.com/blog/2014/05/03/waiting-for-angularjs-digest-cycle/
var waitForRenderAndDoSomething = function() {
if($http.pendingRequests.length > 0) {
$timeout(waitForRenderAndDoSomething); // Wait for all templates to be loaded
} else {
$window.picturefill();
}
}
$timeout(waitForRenderAndDoSomething);
The only issue that the blog post describes is here, so if anyone has anything better please let me know:
The $http.pendingRequests supposed to be used for debugging purpose only. If angular team decides to remove this, you can implement the same using http interceptors as suggested in this link.

Why keyboard accessibility doesn't work for Bootstrap dropdown?

I am trying to make the Bootstrap dropdown keyboard accessible in my page. But I don't know why keydown/up doesn't work. Please see the my jsfiddle demo
And I also have some questions on Bootstrap accessibility. Please help to review it.
According the Issue 931. It seems the keyboard accessibility wasn't added until v3.0.0-rc1. Right?
Why missing href in the anchor element would disable keyup/down accessibility for dropdown?
The problem lies in the following source code of bootstrap's dropdown.js that is using to find index of focused element:
var index = $items.index($items.filter(':focus'))
the problem is that the $items.filter(':focus') don't returns correct element and in this case index will be -1 each time.
I don't know how jQuery's :focus exactly works but this problem can be solved with the following code: var index = $items.index($(document.activeElement)). But anywhere it's not good thing to change something in source code of 3rd-party library.

How do I make the whole of a DNN 7 Container/HTML Module a link?

I have a DNN skin that has some nice containers. I can drop an HTML module onto the page and apply the container to it. I can put a link in the content of the HTML Module, but what I would really like to do is make the whole container/module area a link to another page - in effect as if it were a great big button. How do I do this?
Of course as soon as I posted the question I found a way, but would still be interested to know if this is the "right" way or even a "good" way.
My solution was to take a copy of the container .ascx and add an "onlick" to the outer DIV, which in turn uses JQuery to locate the first tag and to navigate to the href.
<div class="Container-1 Container-1-color1"
onclick="window.location.href = $('a:first',this).attr('href')">
Note: Use window.location.href, not JQuery .click() or .trigger('click') as this creates an infinite loop.
I then added some CSS to show that an action was available when the mouse was over the container:
.Container-1:hover
{
opacity:0.8;
filter:alpha(opacity=80); /* For IE8 and earlier */
border:1px solid gray;
}

Twitter Bootstrap2 100% height responsive

I want to make a responsive layout with twitter's bootstrap v2, with a column and a map.
The idea is to build a UI like that from maps.google.com, but using a responsive design with bootstrap2.
I want to have a style for desktop with
navbar on top
1 left column (as sidebar)
height: 100% minus navbarHeight, with a scrollbar
width: .span3
content that fills the rest of the screen
Then for the responsive mobile design I want the parts that have the full height to have a height depending on the content.
I made a sketch to explain better
EDIT: Looking to do something like this but responsive, and only with north (navbar), west (sidebar), and center (content)
EDIT2: I finally made it with jquery, but I want a CSS solution. If someone asks, I will put the solution as an answer.
EDIT3: Ok, here is the solution I found using JQuery (I think it's easy to do with plain js)
$(window).bind('resize', function() {
if ( $(window).width() > 980 ) {
$("#content").height(($(window).height()-40)+"px")
$("#sidebar").height(($(window).height()-58)+"px")
$("body").css("padding-top","40px")
}
else {
$("#content").height(($(window).height()-50)+"px")
$("#sidebar").height(($(window).height()-68)+"px")
$("body").css("padding-top","0px")
}
$("#sidebar").css("overflow", "auto")
$("body").css("padding-bottom","0px")
$(".navbar").css("margin-bottom","0px")
});
The $(selector).css() functions and the conditional if could be replaced with plain css and the media queries from CSS3 http://twitter.github.com/bootstrap/scaffolding.html#responsive
But the problem is that $(window).height() is calculated runtime. That should be replaced maybe by something like a height:100% in CSS, and that could do the trick, but I couldn't find the right place to put that 100% height.
EDIT4: Here I found what it could be a CSS-only solution! If I make progress, I'll post the answer!
http://blog.stevensanderson.com/2011/10/05/full-height-app-layouts-a-css-trick-to-make-it-easier/
From my investigations this week (I'm trying to accomplish the same thing), it seems like bootstrap and a 100%-height design are incompatible from a pure CSS perspective (unless you want to make changes to bootstrap). I'd be interested in seeing your jquery solution.
I'm not sure that I totally understand what you are looking for, but take a look at http://reactivewebdesign.net/Chicago/Traffic which has a top menu (adding the bootstrap navbar should be easy).
The left column spans 3 columns and the map occupies 9 columns. There is also a link in the left menu named "Where Am I" that also uses a Google map. The css for the map is at the top of the page. If you are looking to squeeze the map into three columns, merely reverse the 3 & 9 to 9 & 3 - it should still work.
Hope this helps.
