We know that each key on the keyboard corresponds to a code, tapping the keyboard, in fact, the computer hardware through the logic gate circuit to generate binary digits to represent this code, and then passed to the CPU. The following is a summary of the char codes supported by javascript: Key Code Backspace 8 tab 9

create and send an HTTP Request] What is an HTTP status code? The HTTP status code is used by the Web server to tell the client what happened. The status code is located in the first line of HTTP Response. A "three-digit status code" and a "status message" are returned ". "Three-digit status code" facilitates program processing, and "status message" is easier to understand. For example, when a client requests a nonexistent URL, the Web server returns "HTTP/1.1 404 Not Found" to the browser clie

When using C ++ to develop a Windows program, we often see the following judgment: Copy codeThe Code is as follows: HRESULT hr =: RegCreateKeyEx (hk, szKeyPath, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_QUERY_VALUE, NULL, hk, NULL ); If (SUCCEEDED (hr )) { In the code, use the SUCCEEDED macro to determine the return value of the RegCreateKeyEx () function.Some Programmers think that when RegCreateKeyEx returns 0, it is successful, and S_ OK is 0. Therefore, it is customary to use the SUCCEEDED macr

HTTP and Status Codes HTTP is a hypertext transfer protocol. The browser communicates with the Web server over HTTP (some other software, such as Im, uses the HTTP protocol to transmit data), transmits our request (HTTP request) to the server, and the server responds to this request, return the HTTP Response and the data we need. This is basically what it looks like. If we request something, the server will return something, so HTTP status

Reading directory: 1. Introduction 2. the type code is replaced by the logical behavior enumeration, constant, and Entity subclass of the object) 3. the type code is abstracted from the logical behavior of the affected object, which is solved by polymorphism) 4. You cannot directly abstract the type code and use the policy mode to solve the problem) 1. Introduction When it comes to type codes, we will be very impressed. In a certain Entity, there

distinguish between the types of data, in fact, a lot of simple, and HTTP status codes is used to pass HTTP processing state, if you use this way to pass the custom processing state, so that HTTP Content can be very simple to pass data, so that the data format is not limited to JSON, can also use other formats (text, XML, HTML), and XMLHttpRequest itself has the ability to handle HTTP Status

First, you need to know what the HTTP status code is: the HTTP status code is a three-digit code used to indicate the HTTP response status of the Web server. When a client sends an HTTP request to the Web server, the server returns a response code. These response codes are mainly divided into five types: 100 status codes, 200 status

as a program developer, you should know the meaning of the HTTP status returned by some servers, and only make sure that the status code one by one is clear and that the various problems encountered in the work can be handled with ease. So let's take a look at the more common HTTP status codes now! 2** Opening (successful request) indicates that the request's status code was successfully processed. 200 (success) The server has successfully processed t

BCD code is often used in PLC Data conversion. What is BCD code and compressed BCD code? What is the difference between the two? In a digital system, all kinds of data must be converted to binary code for processing. People are used to using decimal numbers. Therefore, the input and output of the digital system still use decimal numbers, in this way, a four-digit binary number is used to represent a single-digit decimal number. The binary code used to represent a decimal number is called binary
