What is Chromecast? what function does Chromecast have?
Chromecast is the new connection device that Google released on July 25, 2013. The device runs a simplified version of the chrome operating system, which can be plugged into the TV HDMI interface. In the same WiFi environment, users can push a YouTube video broadcast on a cell phone or tablet to the TV via
and display of the page can not be changed, unless you change the HTML code.
Different transfer speeds
The transmission speed of the Web page is different, it must be due to the different transmission modes. Dynamic Web pages need to be based on the user's request for a dynamic compilation process, that is, the page is not ready-made, but dynamic generation, which requires a number of reading process, each time the interaction of data will greatly reduce the user's access speed. I
official support for Chromecast. In this way, developers only need to use the Google Cast SDK to integrate Chromecast into existing mobile or Web applications and publish it on the Google Cast developer console, this allows users to control the content displayed on large devices, such as televisions, through smartphones and tablets.
For the brand new Google Drive Android API, Google said that in addition
NewS){HOUR=NEWH;MINUTE=NEWM;Second=news;}void Clock::showtime (){cout}Note: The function name is preceded by the class to which it belongs, to indicate which class it belongs to.This completes the declaration of the clock class. First, the class name is declared with the keyword class, and then the data members and function members of the clock class are described, the access control properties of the class members are explained by public and private

Js object-oriented object creation methods. For more information about how to create an object, see create an object:
1. Object literal volume.
The Code is as follows:
Var clock = {Hour: 12,Minute: 10,Second: 10,ShowTime: function (){Alert (this. hour + ":" + this. minute + ":" + this. second );}}Clock. showTime (); // call
2. Create an Object instance
The Code is as follows:
Var clock = new Object

Method
In fact, settimeout and setinterval have the same syntax. They all have two parameters, one is the code string that will be executed, and one is the time interval in milliseconds, and the code will be executed after that time period.However, these two functions are different, setinterval after the execution of the code, after the fixed time interval, it will also automatically repeat the code, and settimeout only one time to execute the code.Althou
Both methods can be used to execute JavaScript after a fixed period of time. However, they have different application scenarios. Method
In fact, setTimeout and setinterval have the same syntax. Both of them have two parameters. One is to be executed.CodeString, and a time interval in milliseconds. After that time period, the code will be executed.
However, there are differences between the two functions. After the setinterval code is executed, it automatically repeats the code after the fixed

Although it appears that settimeout can only be applied to on-off actions, you can repeat the call to settimeout by creating a function loop:File:settimeout_setinterval.js
ShowTime ();function ShowTime (){var today = new Date ();Alert ("The time is:" + today.tostring ());SetTimeout ("ShowTime ()", 5000);}O
