toggling element with javascript is making the element appear too small until I resize the browser

edit
Since originally posting this question, I've gone down a couple more paths trying to solve the issue. It's still not solved, but now my questions are different. The original question is below, and then I'll add a section below that with updates.
original question
I'm working on a Rails 4 application and having some trouble with JavaScript and the Chartkick gem.
I have two JavaScript functions that make it so that a user can click an icon and an element will drop down below the icon/appear on the page, and the icon will switch from a right-pointing arrow to a down-pointing arrow. The code is this:
function ReverseDisplay(d)
{
if(document.getElementById(d).style.display == "none")
{
document.getElementById(d).style.display = "block";
}
else
{
document.getElementById(d).style.display = "none";
}
}
$(function() {
$('.toggle-icon').click(function() {
$(this).find('i').toggleClass('fa-arrow-circle-o-right fa-arrow-circle-o-down');
});
});
And the haml:
%a{href: "javascript:ReverseDisplay('toggle-stats#{item.id}')", class: 'toggle-icon'}
%i.fa.fa-arrow-circle-o-right
%div{id: "toggle-stats#{item.id}", style: "display: none;"}
= the items to be displayed
It works. However, I expect the items that drop down to take up the full width of the page, like so:
But instead, when I first click the toggle icon, they show up squished, like this:
If I then resize the browser just a tiny bit, the graph pops out to full-width, and it stays that way no matter what I do from there. I can't figure out how to get ahold of the generated mark-up, because this chart comes from Chartkick, as a gem. The generated html in the browser has this line:
<div dir="ltr" style="position: relative; width: 300px; height: 300px;">
Where the width: 300px is what's being changed to width: 1000px when I change the browser size. I don't have to change the browser size permanently or significantly. Once that width has changed to 1000px the first time it stays there - but the minute I refresh the page and click the icon to toggle the chart again, it's back to 300px. I don't know how to hook into this div, because it's generated by the gem and I don't know how to add a class to it. I've tried adding styling to a parent element that ensures all of that parent elements' children are width: 100%, but that doesn't do anything.
Anyway, I don't think that adding a class to it is the solution here. I just have no idea what is - I don't JavaScript incredibly well. I'm pretty much completely new to all front-end work as a whole. What's going on here, and how can I make these charts always be the full width of the page when they're toggled?
Notes: Am testing this in Chrome. I tested in Firefox and it does the same thing.
OK, I'm starting to wonder if this has something to do with the fact that I'm using a JavaScript function in order to capture dynamic item IDs - a page may have any number of these toggle-able charts, and so calling a jQuery function on each id seems impossible, because I don't know what ID is.
I removed the jQuery call, however, and the problem persists.
One of those times when rubber-ducking the Stack Overflow question box has not yet answered my question. So I guess I'll submit and hope for outside help here. :/
adjusted question
This question in the Github issues for Chartkick has lead me down a different path. The solution is not necessarily in attempting to restyle the charts at all. Instead, what I'm trying to do is trigger a resize event, because the chart automatically regenerates when the browser window is resized. This is both what's causing the problem and where the solution seems to lie.
My code:
.row
.col-sm-12
%h3.title-block.second-child
Stats by Video
.panel-groupd#faqList
- #claim.presenter.videos.each_with_index do |video, index|
.panel.panel-default
.panel-heading
%h4.panel-title
%a.chart{data: { toggle: "collapse", parent: "#faqList" }, href: "#video#{index}" }
= "'#{video.title}' at #{video.event.display_name} on #{display_date(video.recorded_at)}"
%div.panel-collapse.collapse{id: "#video#{index}"}
.panel-body
- if video.impressions.count > 0
%h4
Impressions by Hours (24 hours)
= line_chart video.impressions.group_by_day(:created_at, range: 1.day.ago...Time.now).count
...a couple more charts
:javascript
$(".chart").click(function() {
window.dispatchEvent(new Event('resize'));
});
So the intention here is that when I click the .panel-heading, this both drops down the .panel-body with the charts in it and resizes the window, which makes the charts resize correctly (or, rather, should).
It kind of works, in that, when I first click the .panel-heading trigger, it does not resize the charts, but when I click it again, the charts are resized perfectly for a split second... just before they become hidden from view again. :(
I've tried adding a time out to the javascript, like so:
:javascript
$(".chart").click(function() {
setTimeout(1000);
window.dispatchEvent(new Event('resize'));
});
But it doesn't appear to do anything at all.
So what I'm wondering here is how to get this resize event to work once the dropdown .panel-body is out so that the charts will resize appropriately on their own.
Here's a screen cast of the current problem, in case I didn't describe it clearly enough:

I don't know anything about Ruby or Chartkick, but in order to override that inline styling, you would have to use !importantin the css.
So, if you try that technique of giving all the children of the parent element width: 100% again, you might want to implement it something like this:
.importantRule { width: 100% !important; }
$( "parentElement > childElement" ).addClass('importantRule');
(First line goes in your CSS file, second line goes in JS)

Trouble with window.print after having altered page elements

I am in trouble with the print function offered by javascript: It doesn't print the current page.
From the beginning: The purpose of the page is to take input from the user, process it and display a result. In fact, it is a simple form with a couple of input fields. With the help of jquery the input given by the user is interpreted and a result is displayed. If the input is satisfactory, a plus sign on a green background in a div-container is displayed. If not, a minus sign on a red background is displayed.
Now, the problem: The user is offered a print-button. That is not 21st century, but a requirement. The printout looks pretty fine thanks to the print.css. But there is one problem: The div-containers only appear in their unprocessed shape. No matter what the input of the user was, the div-containers are printed in their initial state (meaning: gray background).
The div-containers are changed by using the jquery-function addclass() or removeclass(). On the screen, everything works fine. But a look at the source code after having processed the input of the user still reveals an unchanged div-container. Therefore the print result is short of its purpose.
How do I convince the browser to print the altered div container instead of the initial one (as it was at the time of loading the page)? What am I missing here?
For your help, lets have a look at the crucial parts of the source code:
a) how the css files are linked in:
<link rel="stylesheet" href="styles/standard.css">
<link rel="stylesheet" media="print" href="styles/print.css" />
b) how the print button is handled:
$('a#print').click(function(e){
e.preventDefault();
window.print();
});
c) how the div containers are altered:
$('div#result').addClass('res_red');
$('div#result').removeClass('res_green');
$('div#result').removeClass('res_zero');
Again: On the screen everything works fine. Just the print-out is in a mess...

i do not get that.
do you load print.css to all users? or just who clicks the "Print" button?
nothing is wrong in your code. im afraid its just css rules not applying right.
(maybe some !important or just override not strong enough*)
*override not strong enough example:
css:
div.container div.class-a:hover {
color: grey;
}
.container div:hover {
color: red;
}
the last class will not override the first one due to not strong enough selector.
so color remain grey on hover, although the last class written below.

Mootools slide not working in dropdown

I have an html5 page with a dropdown menu using mootools. It's working if I use the hide() and show() functions. But, I want the menu's to slide in and out, like this:
var m = e.getElement(".dropdown-menu, .sidebar-dropdown-menu");
if (e.hasClass('active')) {
m.hide();
e.removeClass('active');
} else {
m.show();
e.addClass('active');
}
Instead of hide and show I want slideIn and slideOut:
var m = new Fx.Slide(e.getElement(".dropdown-menu, .sidebar-dropdown-menu"));
if (e.hasClass('active')) {
m.slideOut();
e.removeClass('active');
} else {
m.slideIn();
e.addClass('active');
}
Working example: http://jsfiddle.net/wzzeZ/

It's not throwing errors; where do I look to fix it?

There are a few things going on here.
First of all, you're not seeing any errors because there are none. If you litter the code with console.log() calls, they all run.
It's a style issue that's preventing the menus from displaying.
The FX.Slide Class in Mootools doesn't seem to explicitly set the 'display' property of the element you're sliding to block. You still need to call .show() for it to work.
Next, if you check out the docs for FX.Slide, you'll notice that it creates a wrapper element to do the slide effect (the container is needed for the height animation, overflow: hidden, etc.)
Unfortunately that seems to be messing with the positioning of the menu, which is positioned relatively to its containing element - but the containing element has height and overflow: hidden styles which then hide the menu (not to mention, even if you could see it, it's in the right place).
To see what I'm talking about check out this updated Fiddle here: http://jsfiddle.net/37V53/2/
If you run that in Firefox with Firebug, and you hover your cursor over the element that's logged to the console, you'll see Firebug's blue hilight appearing where your element actually is being displayed - in the middle of the window, and hidden from view.
This is a combination of assumptions made in the MooTools Classes you're using working against each other; You'll probably be better off writing your own (simple) slide-out script using FX.Tween rather than FX.Slide.
I created a sample of how to do this based on the original Fiddle (that works) - http://jsfiddle.net/LkLgk/
Trick is to show the element to the browser but not the user (by setting visibility: hidden before display: block, grab the height, set height to 1px, visibility back to visible, then tween the height to the previously detected value.
Hope that points you in the right direction; remember, when in doubt, console.log everything!

HTML JS and CSS list marquee not properly displayed

I have modified a code that displays a marquee scrolling a simple HTML list. You can see it here:
I have 3 problems that I can't solve:
JS: I would like the marquee to show the text entering again through the right just after it disappears through the left, something like a continuous marquee, how could I do it ?
CSS: I am noticing (a) some artifacts in the marquee, I think this is due to the marquee text and the margins/paddings of divs not being properly set; and (b) the shadow of the lighter blue div cut over the marquee.. (I think it may be a z-indez problem?). (b) appears with any browser, (a) only with chrome, firefox looks ok. How could I fix it ?
Here's a screenshot:
I can successfully load data from my db and append it to the marquee. Now, I want to "refresh" the contents of the marquee every X seconds, would it be ok to remove the top element of the list when appending one in the bottom, or would it be better to fade-out, update everything, and fade-in again? Any other ways to do it ?

Here is a simple example to deal with scrolling them in from the opposite side. Also, if you adapt this method you can simply add or delete new items in the array as you need too. Watch this and about 2 or 3 times through it will add new items. One important thing to note is make sure the width of the div with id text is wider then the length of all visible items plus the length of the next in line.

How to respond to a click outside a certain area?

My document looks like this:
Basically the background is one full-screen, transparent div. There are couple problems...if I just create the background div and don't apply any z-index to it, it ends up being on top of everything, and I cannot click on the box. If I set the z-index of the background div to be below the box, I can't seem to click on the background. What I want to do, it to be able to click both on the box, and the background.
var x = document.getElementById("bg");
x.addEventListener("click",reset,false);
function reset() {
alert("reset was clicked");
}
CLARIFICATION: box is on the same node level as the bg. it is not inside the bg div.

Take a look at this jQuery plugin - even if it doesn't solve your particular question the code could provide insight into your dilemma.
jQuery clickoutside

You must post your code so every one can help you. My test work correctly on Firefox and Chrome. If I'm guessing right, the background in your code isn't expanded. Try to remove html, body { width:100%; height:100%; } in my example to see the problem.
On IE browser, you need to use a transparent gif image as background of the background div, otherwise the background div may be unable to receive mouse click event.
