QUESTION
I'm trying to increase page speed by loading my Google Maps two seconds after page load. While doing so, I keep on getting "Cannot read property 'extend' of undefined". I know there is some asynchronous loading going on but I'm not sure how to get it in proper order to get this map to load 2 seconds after the page is done. Any help is greatly appreciated.

Answered 2021-Jun-11 at 14:09The initial https://maps.googleapis.com/maps/api/js?key=key
loads additional scripts that are not being captured by your implementation. The package, https://www.npmjs.com/package/@googlemaps/js-api-loader, enables the following pattern and is probably what you want:

I'm using the Angular Material google maps component for integrating Maps in to an Ionic/Capacitor application.
https://github.com/angular/components/tree/master/src/google-maps
The map functionality works perfectly fine when I'm developing the application. When I try to run the test file for the component that implements the Google Map, I get this error:

Answered 2021-Jan-22 at 05:48I can at least show you how I do this using Angular Google Maps. I have an archived repository and website that used to use a Google map with a marker on it here.

QUESTION
When you hover on the provences on the map below, you'll see the name of the provence. How to imitate this behavior with amCharts on mobile? It would be nice if the label appears on mobile when you tap once. Only one label can be visible at the same time.
I've been looking endlessly to find the answer. I couldn't find the answer in the docs either, for example at https://www.amcharts.com/docs/v4/concepts/touch/
Eventually I would like to be able to link to another page when you tap the same province again. So if you tab a provence, and if a label is visible in that provence, then you'll go to another page. The biggest provence on the left (xinjiang) already links to google.com. But I haven't even got a clue on how to listen for the first tap event.
Does anybody, maybe someone with a bit AmCharts experience, have an idea on how to solve this problem?
...ANSWER
Answered 2021-Mar-08 at 14:45The hover state of each province can be toggled by setting event.target.isHover
to true
/false
(this works best when polygonTemplate.hoverOnFocus
is set to false
). The over
event is triggered for each tap, so the hover state can be enabled there (staying that way until the user interacts again). Checking event.touch
allows the behaviour of mouse events on non-touch screens to be unaffected.
The tricky part is that the corresponding out
event does not seem to trigger for touch events. Without this, it's difficult to know whether a tap is the first or second tap on a given province. To work around this, a document.ontouchend
event can be used instead. In this function, check to see if the target
is the last province tapped, so that it can behave as an out
event (this is better, as it will even trigger for a tap outside the chart).
By keeping track of the last tapped province (tapProvince
), this can be compared in subsequent over
events to check for an initial or repeat tap. Finally, by setting event.target.url
to an empty string or the intended URL, it is possible to control navigation.
QUESTION
I have a map with 3 countries which when clicked, display a popup with links and their name. I would like to avoid the popup for the country without links to be displayed.
How can I check the empty array and prevent the popup only for the countries that don't have any information either in the "link"
or "linkName"
?
The popup happens here:

QUESTION
In my current code I have two countries that display a popup when clicked and in the popup you can see some links. Links are mapped correctly but my problem is with the links name.
The way I wrote the code so far, is good for displaying the name of link for a country with one link. I'm calling the link name with ev.target.dataItem.dataContext.linkName
in the code below:
ANSWER
Answered 2021-Feb-04 at 12:23You need to use the index
provided by the .map
to access the nth element in the
linkName
array.
QUESTION
I have some countries on the map that are displaying some links when clicked. They are stored as objects in an array of objects like you can see below.
...ANSWER
Answered 2021-Feb-04 at 10:09The problem was in the loop. I had to take out the following lines out of the loop:
QUESTION
In my JavaScript array of objects, I have a problem displaying multiple links from the objects corresponding to each country on a separate line for each of them.
The current loop takes all the links corresponding to the countries and displays the name of country.
The problem with links is that if a country has multiple links, I can't have them displayed separately.
For example, those three DE links are displayed in tooltip as one single link:
https%3A%2F%2Fwwww.example1.com%2Chttps%3A%2F%2Fwwww.example2.com%2Chttps%3A%2F%2Fwwww.example3.com
and I want each link on a separate line.
How can I write the loop better in order to achieve what I want?
The loop currently looks like this:
...ANSWER
Answered 2021-Jan-27 at 17:31Use map()
to iterate over the link
property and make each URL a separate line in the tooltipHTML
property.
QUESTION
I'm trying to encode some object properties with links in an HTML tag but what I got so far is not a working encoding. If you click on a country, you see some links displayed but they aren't encoded properly.
This is what I tried to do to encode the links from the object but something is missing.
...ANSWER
Answered 2021-Feb-03 at 11:58The links were not encoded properly because .link doens't exist in url.link. I was already in the .link for the mapping.
So, the code would be:
QUESTION
I have a map, where I want to have on hover color change and then on click fixing a color. It glitches in a way that it sometimes starts to activate the on "hit" color even when only hovering (black instead of blue).
It specifically happens when you click on one region and then hover over a neighbor.
FYI you might see it better in fullscreen.
Can you please tell me what is wrong with my code? Thanks
...ANSWER
Answered 2021-Jan-30 at 23:00You had two hit
event handlers. Even if that is not the issue, it is a good thing to have only one... For code readability.
The issue was about the polygon.setState("default");
To be honnest, I don't really know what it does... lol
But what you want to do is to remove the active
"state" on all the polygons... So why not just do:
QUESTION
I am wondering why my 404 page is getting conflicted with my map even though there is no map on my 404 page. I have the following code for my Maps.js
:
ANSWER
Answered 2021-Jan-14 at 05:33This is because you are never unmounting your Map
component and when you navigate to another page (no matter that is 404, it would happen with everyone) it's complaining about that line. Because all the components share the routing, and the code of your map is not being rendered inside the component, it's never unmounted when the component is disposed.
There are a few things in your code, among the issue. You are attacking directly the DOM, however, the reason why you are using React, is to generate a virtual DOM to avoid that kind of high-performance operations. Real DOM operations have a high-impact on web performance as jQuery does. You can achieve the same result using some hooks.
Change your Map component to something like this:
