JavaScript Window - 浏览器对象模型 浏览器对象模型 (BOM) 使 JavaScript 有能力与浏览器"对话"。 浏览器对象模型 (BOM)： 浏览器对象模型（Browser Object Model (BOM)）尚无正式标准。 由于现代浏览器已经（几乎）实现了 JavaScript 交互性方面的相同方法和属性，因此常被认为是 BOM 的方法和属性。 Window 对象： 所有浏览器都支持 window 对象。它表示浏览器窗口。 http://www.iis7.com/a/lm/gjcpmcx/ 所有 JavaScript 全局对象、函数以及变量均自动成为 window 对象的成员。 全局变量是 window 对象的属性。 全局函数是 window 对象的方法。 甚至 HTML DOM 的 document 也是 window 对象的属性之一。 语法：window.document.getElementById("header") == document.getElementById("header") Window 尺寸： 有三种方法能够确定浏览器窗口的尺寸。 对于Internet Explorer、Chrome、Firefox、Opera 以及 Safari： window.innerHeight - 浏览器窗口的内部高度(包括滚动条)。 window

I have an android app that uses location. But I noticed that if users disable the 'Access to my location' in Settings > Location access, nothing works anymore. How can I check that it's enabled? In case it's disabled, how to open those settings from my app? Thanks SOLVED : String locationProviders = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED); if (locationProviders == null || locationProviders.equals("")) { ... startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)); } Prakhar may be this will be useful check this site it discusses

I am working on an android application that determines user location in osm maps. I am being able to show user location on the map, but if the location change the whole map is reloaded, what’s wrong with that? Also how I can increase the accuracy of the user location? And how can I make a circle that increase and decrease according to the accuracy(as shown in Google one)? code : public class OsmDemoActivity extends Activity implements LocationListener, MapViewConstants { private MapView mMapView; private MapController mapController; private LocationManager mLocMgr; private ItemizedOverlay

在Linux中不同的用户都可能用到Nginx，如果不同的用户无法达成一个对nginx.conf编写标准，势必会导致nginx.conf里的内容变的相当混乱，极难维护。所以这里建议新建一个文件夹，这个文件夹中分放不同用户所需要反向代理的配置文件。 nginx.conf 文件尽量不做修改，只需在最末尾加上 include conf.d/*.conf; nginx.conf #user nobody; worker_processes 1; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; #pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"';

In a long tiredsome quest to speed up my site, I have figured out something is wrong with the redirection: currently my index.php handles all the homepage redirections via PHP header location 301 Redirect Permanently: website.com >> website.com/en/home and website.de >> website.de/de/home etcettera etcettera (around 20 for this multilingual website) it takes anywhere from 200ms to 6000ms to do the redirecting. Check out the waterfall! After that, the page loads in a thunderbolt's blink of an eye! What a waste of time wouldn't you say? What is the server doing all this time? After careful

I am writing my own background location updates for interval of every 5 minutes in android. I would like to know the difference between setInterval and setFastestInterval When I setInterval to 5 mins and setFastestInterval to 2 mins. The location update is called every 2 mins. I would like to know the difference. I couldn't understand what exactly is written in the developer page for this https://developer.android.com/reference/com/google/android/gms/location/LocationRequest.html Also: Is there an inbuilt function to check the location updates only if the distances of the first update are more

According to the Android documentation: The Google Location Services API, part of Google Play Services, provides a more powerful, high-level framework that automatically handles location providers, user movement, and location accuracy than the platform location API in android.location . But using the fused location provider (from location APIs in Google Play services) I do not know how to check if the user has the location enabled or disabled. Using the old android.location it was easy: locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); locationManager.isProviderEnabled

JSON基础 现代的web应用一般都面临大量的JSON（JavaScript Object Notation）格式的数据操作。为此Play提供了 JSON 库。 JSON是一种轻量级的数据交换格式，一个典型的JSON结构如下所示： { "name" : "Watership Down", "location" : { "lat" : 51.235685, "long" : -1.309197 }, "residents" : [ { "name" : "Fiver", "age" : 4, "role" : null }, { "name" : "Bigwig", "age" : 6, "role" : "Owsla" } ] } 点击 这里 查看有关JSON的更多信息。 Play的JSON库 play.api.libs.json 包中提供了构造JSON数据的数据结构及转换数据的工具类。此package提供了如下功能： 自动转换 ：从case class和json相互转换的模板代码。可以从这里入手来快速开始。 自定义逻辑校验 自动解析 ：从request body中解析JSON，遇到异常的JSON格式或者不正确的content-type头时会自动产生错误。 此JSON库也可以脱离Play框架独立使用。只需要在sbt文件中加入：libraryDependencies += "com

I have a database of user submitted latitude/longitude points and am trying to group 'close' points together. 'Close' is relative, but for now it seems to ~500 feet. At first it seemed I could just group by rows that have the same latitude/longitude for the first 3 decimal places (roughly a 300x300 box, understanding that it changes as you move away from the equator). However, that method seems to be quite lacking. 'Closeness' can't be significantly different than the distance each decimal place represents. It doesn't take into account that two locations may have different digits in the 3rd
