How does one convert a string to decimal by using JavaScript in hexadecimal conversion?

JS is a magical language. Many internal functions can help us convert data (in;

Javascript can be directly in hexadecimal notation;

Var a = 0xff; // 255.

Convert any hexadecimal string to decimal, such as binary, octal, and hexadecimal. If the second digit is not written, it is the most commonly used integer decimal;

The Code is as follows:

ParseInt ("11", 2); // 3 2 hexadecimal to 10 hexadecimal

ParseInt ("77", 8); // 63 convert the hexadecimal value to the hexadecimal value

ParseInt ("af", 16); // 175 hexadecimal to 10 hexadecimal

Converts a 10-hexadecimal string to a binary, octal, or hexadecimal string.

Object. toString (n): (n) represents the hexadecimal format, as shown in figure

The Code is as follows:

(152). toString (2) // "10011000"; Use brackets to convert "package" to an object, or write the following statement;

152 .. toString (2) // here the first point is to convert 152 to float decimal places, and the second point is the method of extracting objects;

152 .. toString (16) // "98": Convert decimal to hexadecimal

152 .. toString (32) // "4o": 10 hexadecimal to 32 hexadecimal

Similarly, Javascript supports a maximum hexadecimal value of 36 (26 letters + 10 digits)

35 .. toString (36) // "z": supports the maximum encoding "Z", case insensitive

If you need to complete the conversion process. You can use the following method:

The Code is as follows:

/**

* @ Param num the 16 to be filled is a number

* @ Param len the number of digits to be filled. Here is

* @ Returns string after completion

**/

Function format (num, len ){

Var l = num. length;

If (num. length <len ){

For (var I = 0; I <len-l; I ++ ){

Num = "0" + num;

}

}

Return num;
