The study found that in the vehicle spontaneous combustion caused large areas of casualties, many of the seven or eight or even more than 10 people were burned in the vicinity of the car door died, which means that many passengers choose to rush to the door, but because of overcrowding, so that everyone can not escape. In addition, in the event o
This article describes the escape function to solve JS in the Ajax transfer of Chinese garbled problem, to share with you for your reference. The specific methods are as follows:
First, the problem description:

Escape () method
In the MSDN JScript Reference:
The escape method returns a string value (in Unicode format) that contains the contents of [the argument]. all spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with % xx encoding, where xx is equivalent to the hexadecimal number representing the character. for example, a space is returned as "% 20."
Simple translation:
In Unix, there is a special type of character called metacharacters. They indicate special meanings in the system. For example, * and? The operating system considers these metacharacters as wildcards. If these metacharacters exist in the path, file name, or command parameters, the operating system may be misunderstood. Therefore, some methods should be used in the system to enable the operating system to treat these metacharacters as common characters. In Unix systems, the conversion and referen

The famous game developer Bill Volk once wrote an equation "interface + product element = Game" to the game design, which clearly shows the importance of the page in the game design. For mobile game developers, the need to let players in a short time to start, quickly attracted by the game, the game's page design is very important, it should be concise and quick display of the game contains content and operating norms. Like the recen

There have been many symbols of regular expressions before, this article will give you a summary of all the common symbols. All symbols explain the character description \ marks the next character as a special character, or a literal character, or a backward reference, or an octal escape character. For example, ' n ' matches the character "n". ' \ n ' matches a line break. The sequence ' \ \ ' matches "\" and "\ (" Matches "(". ^ matches the starting
Escape (), encodeuri () and encodeuricomponent () are three common methods used to encode strings in Javascript, but their similarities and differences have plagued many JavaScript beginners, today, I will analyze and compare these three methods in detail.
Escape () method
In the msdn JScript reference:
The escape method returns a string value (in unicode format)
It is estimated that many front-end engineers do not know the difference between Escape,encodeuri, encodeURIComponent, or when to use which method, and why these methods should be used, and I will mainly explain the differences and usage of these three methods.Escape Method:Reference MSDN JScript:The Escape method returns a string value (in Unicode format) that contains the contents of [the argument].

Closures only distinguish between escape closures and non escaping closures when they are parameters in a function
After Swift 3, when transitive closures into functions, the system defaults to the non-escape closure type (nonescaping Closures) @noescape, and there must be escape closures for non-escape closure types e

If you randomly hold ten new users at the gate of the Computer City and ask them what they want to buy a new computer, I believe more than half of them will answer "Play Games ". Especially for a large number of students and computers, the time used to play games far exceeds the time used to learn and organize materials. Even for family users, there are also many people playing cards or Mahjong together, or

@autoclosure (Automatic closure) 1: Automatic closure, as the name implies is an automatically created closure, used to wrap the function parameters of the expression, can be said to be a simple syntax. 2: Automatic closures do not accept any parameters and are invoked to return the value of the expression being wrapped in it. 3: The benefit of automatic closures is that you can delay the evaluation because the code snippet will not be executed until you call the closure, so you can control when
