Snack I have a bar chart application with filters. I have included a side menu in the app. I need for the bar chart to display on the main screen and filters to display in the side menu. Currently, my bar chart is overlayering the side menu, like this-
I am not sure how to organize content on the main screen or the side menu. Maybe I am using the wrong package? The filters interact with the bar graph, that's why they can't be written out in different functions.
If viewing the snack, Clicking anywhere on the screen opens the side menu.

QUESTION
I currently have a problem with Google's Invisible Captcha. It refuses to load properly despite all my attempts.
The situation: I have a form which is added to the DOM via jQuery when clicking on a button. The form is then displayed in an overlayer which covers the entire screen. At first, no worries but once the form is displayed, I try to render the captcha without success, which prevents doing the execute and thus using the captcha on the form.
Here is the insertion code of my form (which works):

event, i.e. the widget ID is an integer starting at 0 for the first widget rendered.
As render is explicit, I would take the approach of specifying all the parameters in the render

QUESTION
I'm trying to put together a page that has several maps (one that contains all of a group of routes and one each for each route), each in a different (Bootstrap) tab. I got it to work with the most repetitive code, by repeating and independently assigning to each map the click and pointermove events I would like, but ideally I would assign these in some kind of loop.
My attempt is what I've pasted below, which works, but only for the final map - if I change the order of the maps any of them will work, but only so long as it is the last. I wasn't able to find much direction on what I'm looking for, this other question being the closest, which mentions the same issue of only working on the last map, though I wasn't able to make much use of the answer provided. Is there a way to loop through these events and have them work over multiple views/maps?
Any direction is greatly appreciated!
Javascript:
...ANSWER
Answered 2020-Jun-07 at 21:14Like was said in the question you check, it is a problem of context.
In the handlers of every event, you are using variables that take value on the loop, elem
, olay
, view
. The problem is that when the events occur the value of these variables reference the last map, overlay, and view of their respective array.
There are several ways to solve this. I will propose you to use bind
method of function (JavaScript - function bind).
QUESTION
I'm looking for a way to render a hover feature vector only over that feature, to essentially render the hover vector over its feature without rendering over other features (specifically, LineString hovers not rendering over proximate markers)
I have hovering set up without issue as per the vector example, the features all rendering in the order I would like (LineStrings are below markers). The issue is that when a LineString is hovered over its hover feature is rendered not only over that LineString but also any marker that the LineString crosses under, and so there is a big streak of the LineString's hover over that marker. I can see how this makes sense just considering how the feature-overlaying vector works, but I can't see how to adjust it as I would like.
I've found several posts that seem to offer incongruous advice on setting a zIndex in the styles or using a renderOrder function, though none have seemed exactly applicable to this situation, or are beyond my n00b capacities. I have tried setting a zIndex on all concerned Styles as well as something along the lines of this renderOrder function, but not to the desired effect. Specifically with the latter, I couldn't figure out where to put the function so that the hover might render according to it.
Any advice is greatly appreciated!

The basic idea is you need separate hover layers for the route and the icons (top to bottom):
- Icon hover layer
- Icon layer
- Route hover layer
- Route layer
This will mean that say an unhovered icon will draw over the top of a hovered route.
ZIndex
You can't use the style zIndex as it applies only to features within a layer. That is, the layer zIndex has a higher precedence than the style zIndex. In your plunkr I couldn't get the layer zIndex to work at all, but it is implicit in the order the layers are added.
So, you need to:
- create separate hover layers
- setup the layers in the order I gave above
- when hovering a feature, move it to the appropriate hover layer
- when unhovering a feature, remove it from the appropriate hover layer
Style Cache
Another thing, your style cache implementation was rather dubious. In fact you do not need a style cache as your are using layer styles and they are only assigned/created once.

Java 8 and Mac OS (High Sierra) here. I have the following class TextOverlayer

QUESTION
I am trying to add new layers to the map using the leaflet. First I create the layers by a form then I put the elements related to their relationship. The problem is that to add a new layer to the overlayers object is using static code, and I wanted to use all the layers that I am creating and are downloaded from the database. Does anyone have an idea?
