穿精又带淫゛_ 提交于 2019-12-08 15:26:30
BOM概念   BOM是Browser Object Model的缩写,简称浏览器对象模型。这个对象就是window BOM提供了独立于内容而与浏览器窗口进行交互的对象 BOM由一系列相关的对象构成,并且每个对象都提供了很多方法与属性 BOM缺乏标准,JavaScript语法的标准化组织是ECMA,DOM的标准化组织是W3C BOM最初是Netscape浏览器标准的一部分 由于BOM主要用于管理窗口与窗口之间的通讯,因此其核心对象是window。 window对象介绍,内置对象(location/history/navigator)及方法: // 什么是window对象,window对象是浏览器内置的一个对象,相当于BOM的一个抽象 // window对象是js中全局对象的寄存地。 window对象的常见方法: alert(要显示的文本); //弹出信息框 prompt(提示对话框信息); //弹出输入框,点击确定,返回字符串,点击取消,返回null confirm(提示文字); //点击确定返回true,点击取消返回false close(); //关闭浏览器(火狐不支持!),但都支持通过别的网页打开的新的网页关闭 //不允许关闭非脚本打开的页面 open(url,name,feature,replace); //open('http://www.baidu.com','

Ask for location permission during runtime in Android

别说谁变了你拦得住时间么 提交于 2019-12-08 14:01:53
问题 I have a very simple app which takes location data from Google's fused location provider API and displays it. Now, for Android M+, I want to ask for location permission during run-time. Below is some relevant code from my MainActivity.java file: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); if(checkAndRequestPermissions()) { // carry on the normal flow, as the case of permissions granted.

Unity3D - Get smooth speed and acceleration with GPS data

倾然丶 夕夏残阳落幕 提交于 2019-12-08 13:43:29
I'm using Unity3D and I created simple distance, speed and acceleration calculator using latitude and longitude of last position. I'm calculating last distance, speed and acceleration in each GPS update (approximately once per second). But sometimes (2-3 second interval) latitude and longitude values changes rapidly (in clear weather and no obstacles). That's why speed and acceleration values gets unreal results. For example, at stable 40 km/h speed, speed value becomes 60 km/h and returns to 40 km/h within 2-3 second. I'm here to ask how can I avoid this inaccurate and rapid GPS data changes?

Android: I want to obtain location using GPS in the background for use with a directions tool in my app, how?

问题 One of the activities for my company's app has a directions utility that allows the user to input their postcode, choose one of our offices, and Maps will route from the given postcode to one of our offices. Leaving the postcode field blank results in Maps defaulting to 'your location', however you need to click 'Go' in the Maps app for it to work, while providing a postcode will automatically do the routing without having to make that extra click. This is a small but necessary thing that

Trouble connecting to GooglePlayServices on AVD

情到浓时终转凉″ 提交于 2019-12-08 13:23:59
问题 I am currently trying to access the GooglePlayServices. The internet for all the other functions on the AVD (API 23) works fine, however I am not quite sure what the problem is on my actual app. Everytime I try to connect, it says that Connection has failed. I believe I have set up the GoogleAPIClient correctly, though in the ConnectionRequest, I have not customised any of the settings (for simplicity's sake). This is some of my app's code to provide some information. Manifest.xml <?xml

Xe5 locationsensor distance doesn't work?

问题 I use in my app TLocationSensor on Android but I have a problem with Distance property. If I set 10 meters and I don't move OnLocationChange is fired. What should I set and how to make it work ? 回答1: Probably the XE5's location sensor component does work - it is just the device incapable of providing Delphi accurate enough data under given circumstances. You can take some mapping software like MapSoft Navigator and record a track for few hours. If that track would show the significant
