How to test leaflet based maps using testcafe?

由 我们两清 提交于 2020-04-15 03:55:35
问题 We are building a series of tests using TestCafe. How do we test if a point or path in a leaflet control is rendered correctly? To be more specific we are trying to test the lat-lon data of a circle marker in the map. But, we do not have any leaflet map/marker object available in the scope of testcafe scripts. References: Unit testing leaflet maps 回答1: I created a simple example of an assertion for a path element in a leaflet control on the getting started demo page https://leafletjs.com

Disable horizontal repeating of world map with mapbox

问题 I'm quite new to JS, so maybe my problem will be easy to solve, though I already spent many hours on it. I'm using Mapbox with the leaflet api, and I would like to disable the repeating of horizontal world maps when zooming out. I already explored the maxBounds properties, but it is not satisfying, as I want to hide the map outside the bounds. Basically, I would like to have this result http://jsfiddle.net/zF6bf/ but instead of "canvas", I would like to have this map, stored on mapbox.com :

问题 I want to draw a curved polyline between two points on a map with the Mapbox SDK. I could not find any solution from the Mapbox SDK. The Turf library is not ready yet to use it on Android. 回答1: I found a solution with the google maps sdk so I converted it to use only the Mapbox sdk : Inspired by Can I draw a curved dashed line in Google Maps Android? public static List<LatLng> computeCurvedPolyline(LatLng from, LatLng to, double k) { //Calculate distance and heading between two points double

Loading 100-200K markers on google map

由 我怕爱的太早我们不能终老 提交于 2020-04-08 08:59:25
问题 At the moment I'm using Google Maps v.3 API for drawing markers on the map. I have around 500 markers in total. For displaying purposes I use markerCluster and group markers using this tool on the client side in the browser. However, I plan to expand the locations number and assume it can grow to 100K or even 200K quickly. I did some stress tests, and realized that current solution basically kills the browser and about 10-20K markers. So my question what is the best approach to draw that many

1 题目： Given a roman numeral, convert it to an integer. Input is guaranteed to be within the range from 1 to 3999. 2 思路 和上一道反过来，好吧，但是思路不一样。 我写的代码思路一样，要考虑一些特殊情况，比较复杂。 别人代码的思路倒是不错： 下面的那个思路，倒序遍历，如果大于5或50或500，那么就是减了，否则就是加。罗马数字小数字在左边是减，且仅限一位。 https://leetcode.com/discuss/2369/solution-for-this-question-but-dont-know-there-any-easier-way 这个是用 哈希函数实现的，我也想过用哈希函数，但是不是这样的，我想的是那个数组全部哈希一遍- -。 https://leetcode.com/discuss/23778/my-accepted-java-code-280-310ms 3 代码： 我的 public int romanToInt(String s) { String[] M = {"","M","MM","MMM"}; String[] C = {"","C","CC","CCC","D","CD","DC","DCC","DCCC","CM"}; String[
