I want to generate an array in jQuery/JS, which contains "code"+[0-9] or [a-z]. So it will look like that.
code0, code1 ..., codeA, codeB
The only working way now is to write them manually and I am sure this is a dumb way and there is a way to generate this automatically.
If you give an answer with a reference to some article where I can learn how to do similar stuff, I would be grateful.
Thank you.
For a-z using the ASCII table and the JavaScript fromCharCode() function:
var a = [];
for(var i=97; i<=122; i++)
{
a.push("code" + String.fromCharCode(i));
}
For 0-9:
var a = [];
for(var i=0; i<=9; i++)
{
a.push("code" + i);
}
I'm using the unicode hexcode to loop through the whole symbols from 0-z:
var arr = [];
for (var i = 0x30; i < 0x7b;i++){
// skip non word characters
// without regex, faster, but not as elegant:
// if(i==0x3a){i=0x41}
// if(i==0x5b){i=0x61}
char = String.fromCharCode(i);
while(!/\w/.test(char)){char = String.fromCharCode(i++)};
// generate your code
var res = "code"+char;
// use your result
arr.push(res);
}
console.log(arr);
Here goes your example.

JS Array and it's methods
you can generate array in javascript by using following code.
var arr = [];
for (var i = 0; i < 5; i++) {
arr.push("code"+ i);
}
please refer following links.

a = [];
for(i = 48; i < 91; i++) {
if (i==58) i = 65
a.push("code" + String.fromCharCode(i));
}
alert(a.join(',')) // or cou can print to console of browser: console.log(a);
