QUESTION
Happy new year everyone! So I'm building a Calorie Calculator and I'm having a slight issue.
I have basically 4 Variables that I want to sum up and display:
- Total Calories #total
- Carbs
- Fats
- Proteins
I'm successful in 2/3/4, however, I get an error for 1. Can't figure out why. Only the "main dish" part of the calculator works, so please click on it, and then the "bases" will roll down. Once you select a menu item from there, you'll see the issue.
Also, this is not a must but would be appreciated, I would like to place a + sign overlay on the menu items when you hover over their image right in the middle. I can't seem to get it right with CSS. If any veterans have an idea that would be appreciated. (I was playing around with the position and top properties but I couldn't get it right)
So here's the code:

I am aware about combineLatest()
to combine the last values in two to six Flux instances (Combining Publishers in Project ). However, assume I have a List> listOfFlux
. Is it somehow possible to combine all of them into one, like e.g. listOfFlux.combineAllLatest( (a,b) -> a + b) )
?

QUESTION
i was going through the algorithm for converting hsv to rgb color space & found this on wikipdia. https://en.wikipedia.org/wiki/HSL_and_HSV. I found on eimplementation for this algorithm here.https://axonflux.com/handy-rgb-to-hsl-and-rgb-to-hsv-color-model-c.
but as far as i can see how are two related and what is the math behind arriving these calculations.
here is the code
...ANSWER
Answered 2018-Jul-06 at 10:10The easy way it is to design it by yourself (and then check the differences), and it is easier to do the inverse way: from RGB to HSV. Your formula should be just the mathematically inverse operation (do it with floating point, or you will lose information). In following explaination I'll use values from 0 to 1 (so scale by dividing with 255, if you are using 8-bit RGB).
Value is just defined as the maximum value of RGB (just to keep thing simpler), if you need brightness, you should weight the 3 channels and sum them. With this definition (of value), we can have the brightest Blue, Red, and Green with same value, which it is handy for colour picker. OTOH we know that a complete blue screen (full with [0,0,255]) is darker then a completely green screen [0,255,0].
Hue indicates the pure colours (if fully saturated), the colour on a colour wheel. These are done by mixing just two components of R,G,B (the third component should be 0). Why this? Take a typical CIE xy figure (e.g. on https://en.wikipedia.org/wiki/SRGB). Pure hues are the spectral colours, so with just one wavelength (the outer colours) plus the line of purples (the lower line), so mixing deeper violet with deeper red. With RGB we can display just the content of triangle (+ the colours on the missing z (or Y) axis). So the most similar and purer colours are the colour on the edge of the triangle between the R, G, B points. And points on a triangle have just one or two components. [CIE xy figures is nice because mixing two colours should be in the line between the two colours].
One of the property of good colour wheel (for mixing, not perceptual) is:by mixing one colour with the opposite (on the wheel), one get grey. So opposite colours are opposite also on the wheel. So we have 6 colours: red [255,0,0], yellow [255,255,0], green [0,255,0], cyan [0,255,255], blue [0,0,255], and magenta [255,0,255]. These are the six cases, 60 degrees apart. So if you have [255, 20, 0] you are 20/255 from red to yellow (where 255/255 is 60 degrees). If you write down all cases, you see that you can eventually simplify calculations [which is usually done in common libraries]
Saturation: Full saturation is like hue (so one component is zero) and full unsaturated colours are greys (or black or white) so with all components with the same value. So the differences of maximum component with minimum component is a saturation.
Why not taking the minimum, as in some formula? This is also a good definition (and maybe more precise), and used on some places. But a darken colour is seems also unsaturated (so "mixing" black or white should have similar bahaviour, so the differences instead of minimum). Ihis manner (difference), saturation is independent of value, and it is more intuitive for a colour picker. The saturation is than divided by maximum component value. Also this is just to have a 0 to 1 number for every case.
Exceptions: then there are some expection (you will see if you implement the calculations, e.g. if all component values are equal, the hue is defined as zero (it do no matter: full unsaturated colours do not have hue). Saturation of black cannot be calculated (zero divided by zero), but it is unsaturated colour, so we set it as 0.
If you derive the inverse, you see your formula.
Note: these calculation are usually done for RGB (so they are not real hue or saturation, or lightness), and for colour picker, so standardized value from 0 to 1 (or 100, or 360 for hue). In reality minimum saturation (so maximum colorfulness) depends in hue. Saturation should depend on brightness, etc. So a more physical color picker should not be a circle (cylinder, double cone), but a figure with more complex form. Which is not efficient for storage (lost of information e.g. by putting in integer: not all combination are valid), and often less intuitive.
QUESTION
I have a calorie calculator working here:
http://www.padthai.decorolux.com/Calorie/
Thing is, it works fine, but when I try to filter on a calorie with an iphone 6 / 6 plus, it registers my click events in the wrong place. Meaning I can't unfilter my diet preferences.
Any idea as to what might be causing this?

QUESTION
I'm building a calorie calculator and ran into some issues. I want to filter based on certain diets. The elements that do not fit the description get greyed out, and become unclickable. All works fine on desktop, none of these however take effect on mobile. I have no idea why, I tried playing around with opacity, fadeout and css settings but nothing seems to do the trick.
here's the js:
...ANSWER
Answered 2018-Apr-13 at 11:01The problem is : you have some elements on a top/z-index of the buttons like #vegetarianDescription, #glutenFreeDescription, #noAddedSugarDescription, #lactoseFreeDescription, #veganDescription
with opacity
and #dietDescriptionTexts
as well .. you need to use display : none;
for them or use z-index : -1
or max-width :0
when you trying to hide them

I'm trying to animate buttons with jquery. On the desktop they are fine, but on mobile the buttons dissappear after two clicks.
I can't figure out how to tell it that if the class is only "fa" then automatically add "fa-plus" to the class. Can someone point me in the right direction?

QUESTION
ANSWER
Answered 2018-Mar-27 at 04:26You would need to split your path into two parts (ie. one for the top part, and one for the second part after the turn) to make it stay on top when it folds under.
Or you could turn off auto rotation completely, so it stays upright (see below).

I'm trying to build a dropdown menu.
- Opens when clicked on.
- Stays open when submenu item is clicked on.
Closes when I click anywhere else on the screen.
Is OK.
- Not OK.
- Is OK.
I can't find the fault in the logic I used, any help is appreciated!
Thanks!

QUESTION
I'm in pain. :)
I'm creating a calorie calculator which has a dropdown for certain dietary preferences. I have it set up so that when a user clicks on the button, the dropdown appears. When a user clicks outside the button, it disappears.
I want two things that I seem to be unable to achieve.
Clicking on the button again makes the class "show" disappear from "#myDropdown"
When the dropdown is "show" I want to associate the 'fa-plus-down' next to the button, when it's 'closed' I want the 'fa-plus-up' icon next to it.
// 1. is the most problematic, I can't see where the logic is help. Any input is appreciated. //
...ANSWER
Answered 2018-Mar-07 at 13:50Since you are using jQuery, I wrote you the functions in it.
The first function opens and closes the dropdown menu on a click on .dropbtn
using slideToggle()
for the dropdown and toggleClass()
for the icon (note that it toggles two classes).
