This article mainly introduces how to convert JavaScript from octal to decimal, which is very detailed and has certain reference value. Friends who are interested must finish reading it!

In JavaScript, you can use the parseInt () function to convert octal numbers to decimal numbers. This function is used to parse strings, and the returned result is a parsed integer. When the parameter is set to 8, you can convert octal to decimal with the syntax of "parseInt (string,8)".

How to realize Octal to Decimal in JavaScript

The parseInt () function parses a string and returns an integer.

When the value of the parameter radix is 0, or when it is not set, parseInt () determines the cardinality of the number based on string.

When the parameter radix is omitted, the cardinality of the default number for JavaScript is as follows:

If string starts with "0x", parseInt () parses the rest of the string into hexadecimal integers.

If string starts with 0, ECMAScript v3 allows an implementation of parseInt () to parse subsequent characters into octal or hexadecimal numbers.

If string starts with a number from 1 to 9, parseInt () parses it to a decimal integer.

ParseInt (string, radix)

String is required. The string to be parsed.

Radix is optional. Represents the cardinality of the number to parse. The value is between 2 and 36.

Examples are as follows:

123 [xss_clean] (parseInt ("12", 8))
