JS encoding text involves 3 functions: Escape,encodeuri,encodeuricomponent, corresponding 3 decoding functions: Unescape,decodeuri,decodeuricomponent
1, the transfer of parameters need to use encodeuricomponent, so that the combination of the URL will not be # and other special characters truncated.
For example:
2, the URL jump can be used as a
Escape () method:
The specified string is encoded using the ISO Latin character set. All spaces, punctuation, special characters, and other non-ASCII characters will be converted into%XX-formatted character encodings (XX equals the encoded 16 digits of the character in the character set table). For example, spaces's corresponding encoding is%20. The Unescape method is the opposite. Characters that will not be encoded by this method: @ */+

Label:If you want to query in SQL like with an underscore ' _ ' or a '% ' equivalent of a record, write directly to like ' xxx_xx ', then ' _ ' will be treated as a wildcard character like. The escape clause is provided in SQL to handle this situation, and escape can specify what escape character is used in like, and the character after the
JVM Escape Analysis
The JVM is composed of stacks, heaps, method areas, local stacks, etc.
Stack: Each method is executed at the same time to create a stack frame for storing local variable table, Operation Stack, dynamic link, method exit and other information. Each method is called until the completion of the process, corresponding to a stack frame in the virtual machine stack from the stack to the process of the stack.
Heap: When instantiating a
Escape () method, which is used to escape any character that cannot be sent correctly in clear text. For example, a space in a phone number is converted to character% 20, which allows the characters to be passed in the URL.Http://localhost:8080/a?name= "+escape (" AA ") +" password= "+escape (" People's Republic of Chi

For example, in a data table there is a field called
orderis specifically used for sorting, and my statement may have to be written like this.
$sth = $pdo->prepare (' SELECT * FROM table_name ORDER by order ASC '); $sth->execute ();
But because order itself is a keyword, then in the execution of the time will be reported syntax error, I know in PDO in the field can be used :column_name to dynamically bind, it will automatically handle the quotation marks and other problems, but also can be used

This article mainly introduces the differences between escape (), encodeURI (), and encodeURIComponent (). For more information, see the following three functions in JavaScript that can encode strings: escape, encodeURI, and encodeURIComponent. Three decoding functions are involved: unescape, decodeURI, and decodeURIComponent.

Escape analysis in English for escape analyses. In the principle of computer language compiler optimization, escape analysis refers to the method of analyzing pointer dynamic range, which is associated with pointer analysis and shape analysis of compiler optimization principle.

In front-end development work, it is often necessary to escape the left and right angle brackets of HTML into solid form.

Escape analysis is an analytical technique that provides the basis for other optimization methods, and its basic behavior is to analyze the object's dynamic scope: When an object is defined in a method, it may be referenced by an external method, such as a call parameter passed to another method, called a method escape. It is even possible to be accessed by external threads, such as assignment to class vari
