google maps js api blocks ui when adding markers

由 生来就可爱ヽ(ⅴ＜●) 提交于 2020-05-16 22:41:06
问题 I have a problem with google maps on mobile browsers. The project I'm working on requires about 500 markers to be shown on a map, but when adding them, the ui freezes. I'm using markerclusterer to add markers, and performance is fine once the markers are on the page. Is there a way to add the markers asynchronously, or to pause adding markers once the user starts scrolling? This is the code we're using: var mcOptions = { gridSize: 50, maxZoom: 15, zoomOnClick: false }; var mc = new

I've successfully stopped the usual context menu from appearing by overriding it as follows: window.oncontextmenu = function (event) { event.preventDefault(); event.stopPropagation(); return false; }; I've also

I am developing an application to detect the lesion area, for this I am using the grabcut to detect the ROI and remove the background from the image. However in some images it is not working well. He ends up not identifying the borders of the region of interest well. The watershed can better identify the edges for this type of work, however I am

Locking down a REST API to one app. How?

由 别来无恙 提交于 2020-03-25 17:11:34
问题 I have a small one page browser based app which consumes a REST API. Users are authenticated via a shortish lived token based system. I'm likely going to expand this to also include mobile apps (either native or hybrid) which will also consume the same API. I do have one concern though - how can I 'lock' my API so that only my apps can consume it? In other words, how can I stop someone else building an app that uses my API? 回答1: You need some sort of authentication, and if you're going to do
