This article mainly explains "JavaScript how to achieve binary conversion", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "JavaScript how to achieve binary conversion" bar!

JavaScript to achieve binary conversion methods: 1, the use of parseInt () function, syntax "parseInt (value, to parse the value of the cardinality)"; 2, the use of toString () function, syntax "decimal number .toString (need to convert the base)".

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

I. grammatical explanation

1. ParseInt ()

ParseInt: convert strings to integers

ParseInt (string, radix)

The string to be parsed by string.

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

If the parameter is omitted or its value is 0, the number is parsed on the basis of 10.

If it starts with "0x" or "0X", it will have a base of 16.

If the parameter is less than 2 or greater than 36, parseInt () returns NaN.

2. ToString ()

The toString () method belongs to the Object object, which is overridden by many of JavaScript's built-in objects to better suit its own functional needs.

The type behavior description Array converts each element of Array into a string and concatenates them in turn, concatenating the two elements with an English comma as a delimiter. Boolean returns "true" if the Boolean value is true. Otherwise, "false" is returned. Date returns a text representation of the date. Error returns a string containing the relevant error information. Function returns a string in the following format, where functionname is the name of a function whose toString method is called: "function functionname () {[native code]}" Number returns a string representation of the numeric value. You can also return a string in the specified base, please refer to Number.toString (). String returns the value of the String object. Object (default) returns "[object ObjectName]", where ObjectName is the name of the object type.
