QUESTION
I have a particular css setup - not really ideal but the "main" element selector is dedicated to having this background-color: white;
and I can't change this.
I can edit the rest and add more css if necessary. Below is a minimised example of the issue using div
in place of body
so I can show both versions in one snippet.
I apply a background image with my div
element and then I need the main
element within it to have a different background-color (i.e. overrule the main
selector)
So I used an id #num1
with the different background colour applied. Works fine.
On the second example, why does none
not work? Why does a colour application overrule but none
just reverts back to the white colour?
ANSWER

isn't a colour, it is an image (or lack of one) and a valid value for the background-image
property.
transparent
is a colour.
You might be getting confused because the background
shorthand property will default to transparent
if you don't specify a colour and none
if you don't specify an image making background: none
equivalent to background-image: none; background-color: transparent
.
That said the element with the id
num2
doesn't have a background colour specified, so it is already transparent
.
There is no colour you can set on it that will make it punch a hole through the background colour of the main
element it is inside.

I'm using React and I have the following situation.
I have one parent div with onClick
event, which takes full width and inside that div I have an image. I want to be able to know where it is clicked. Thus, I want to know if image (child) or div(parent) is clicked.
My code is as follows:
...ANSWER
Answered 2021-Apr-13 at 10:04You have pointerEvents
set to none
in your img
's inline style
object. Remove that. Can remove zIndex
as well.
From CSS-Tricks:-
pointer-events:none
prevents all click, state and cursor options on the specified HTML element
You don't need e.stopPropagation()
here. Just set the event handler only on parent like so (this is known as event delegation) :-
QUESTION
I'm trying to create a slide show (2-3 images) using the Alexa authoring tool.I have managed to do this using the APL Pager which displays a series of components one at a time. The thing is that in order to switch from image A to image B..C I have to touch the screen and swipe left/right. i want to make this happen automatically and have alexa swicth the images within a certain time, and it seems that this can be achieved using APL autopage but for some reason this is not working 😩
What I've done- Set up the APL using the APL pager
- Added the auto page to the APL document
- Component Id
- duration
- delay
After trying the simulation and directly in an echo show 5 it still only triggers when the display is touched.
Also tried:
- Adding the standard command (auto pager) directly in the handler of alexa but same response.
Does it matter if i put the commands in the APLdocument.json[1] file or directly in the handler when i call .addDirective[2]..the only difference i see if i want the content or duration to be dynamic i should put it directly in the backend code(index.js) right?

I am trying to render the image over existing image or over existing panel, but I am getting an error.
According to documentation renderTo:
could be followed by the id of the element, a DOM element or an existing Element that this component will be rendered into.
However, I am always getting error. Here is my code:

Answered 2021-Jan-13 at 15:41Try to avoid access HTML from ExtJs. The framework hides it from developers. The panel is not rendered at the moment when you are initialising the your panel, you must put appropriate logic in the afterrender event handler:

This bug applies to this particular Lightningchart JS example found here.
Steps to reproduce:
Go to line 134 of the provided source code.
Replace lines 134 to 136 with the code below. This code simply generates 30 days' worth of OHLC data in 15 min intervals.

ANSWER
Answered 2020-Dec-18 at 11:48This is a bug and it's going to be fixed in a future release.
The issue comes from inconsistent default value for series max point count, which defines how much data is kept for visualisation. All other series have the max point count set to 0
which means the feature is disabled.
As a workaround you can call setMaxPointCount(0)
on the area series.

Hi all, I'm trying to let this ECG (https://www.arction.com/lightningchart-js-interactive-examples/edit/lcjs-example-0150-ecg.html) work without nodejs or nmp. I've seen that is possible to use IIFE js version. Implementing the IIFE version on the website i find an error running the above command, I'm not able to execute in in my webserver. How can i run it? Is there an IIFE version of xydata? What script do i have to include and how? Thanks
...ANSWER
Answered 2020-Nov-05 at 13:47xydata
can be run directly in browser by using the .iife.js
version of the xydata build. You can either download the @arction/xydata
package from npm and use the xydata.iife.js
file from there or alternatively you can use a CDN like UNPKG.
