Convert the string to decimal by using JavaScript in hexadecimal notation.

Convert the string to decimal by using JavaScript in hexadecimal notation.

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;

Copy codeThe 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

Copy codeThe 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:

Copy codeThe 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;
}

Create a JavaScript program and use the type conversion function to convert the string to the decimal, octal, and hexadecimal values.

Not all strings are English letters and numbers.
Do you want to convert only English letters and numbers?
If so, it's an ASCII code! Write it according to the corresponding rule!
Problem Hi me!

How to use javascript to convert decimal to hexadecimal

Function dec2hex (num) {if (typeof num! = 'Undefined') {return Number (num). toString (16 );}}
