JavaScript method to get the ASCII code corresponding to a character

The following editor will bring you an example of JS obtaining the ASCII code corresponding to the character. The editor thinks it’s pretty good, and now I want to give it to you and give it as a reference. Let’s follow the editor and take a look.

Sometimes you need to use the ASCII code of a character, and you may forget the number corresponding to the character and the ASCII code during debugging.

Recently, I like to use the browser console to run JS code directly. Paste this code directly to the browser console to debug (Google Chrome shortcut key ctrl+shift+j)

function GetAsciiCode(){
var str = prompt("请输入几个字符","");//接收字符串
var strAscii = new Array();//用于接收ASCII码
for(var i = 0 ; i < str.length ; i++ ){
strAscii[i] = str.charCodeAt(i);//只能把字符串中的字符一个一个的解码
}
var getAscii = "";//把这些ASCII码按顺序排列
for(var i = 0 ; i < strAscii.length ; i++ ){
getAscii += strAscii[i];
getAscii += " ";
}
alert("这些字符的ASCII码依次是："+getAscii);//输出结果给人看
}
GetAsciiCode()

ASCII codes corresponding to common characters

a-z 97-122
A-Z 65-90
0-9 45-57
