How can I split the value of a textbox into an array containing each individual char and access that array?

I would like to split the textbox value in each character and replace each array value that is carried by the equivalent in the other array. The value in the text box can always have different lengths. But how can I do this? Do I need to create a new array?

eg:

if textbox value: AaBbCc

the new array should contain: A, a, B, b, C, c

var charsv = new Array();
charsv[" "] = 128; charsv["!"] = 01; charsv['"'] = 02; charsv["#"] = 03;     
charsv["$"] = 04; charsv["%"] = 05; charsv["&"] = 06; charsv["’"] = 07;
charsv["("] = 08; charsv[")"] = 09; charsv["*"] = 10; charsv["+"] = 11; 
charsv[","] = 12; charsv["-"] = 13; charsv["."] = 14; charsv["/"] = 15; 
charsv["0"] = 16; charsv["1"] = 17; charsv["2"] = 18; charsv["3"] = 19;
charsv["4"] = 20; charsv["5"] = 21; charsv["6"] = 22; charsv["7"] = 23; 
charsv["8"] = 24; charsv["9"] = 25; charsv[":"] = 26; charsv[";"] = 27; 
charsv["<"] = 28; charsv["="] = 29; charsv[">"] = 30; charsv["?"] = 31; 
charsv["@"] = 32; charsv["A"] = 33; charsv["B"] = 34; charsv["C"] = 35; 
charsv["D"] = 36; charsv["E"] = 37; charsv["F"] = 38; charsv["G"] = 39;
charsv["H"] = 40; charsv["I"] = 41; charsv["J"] = 42; charsv["K"] = 43; 
charsv["L"] = 44; charsv["M"] = 45; charsv["N"] = 46; charsv["O"] = 47; 
charsv["P"] = 48; charsv["Q"] = 49; charsv["R"] = 50; charsv["S"] = 51; 
charsv["T"] = 52; charsv["U"] = 53; charsv["V"] = 54; charsv["W"] = 55; 
charsv["X"] = 56; charsv["Y"] = 57; charsv["Z"] = 58; charsv["["] = 59; 
charsv["\\"] = 60; charsv["]"] = 61; charsv["^"] = 62; charsv["_"] = 63; 
charsv["`"] = 64; charsv["a"] = 65; charsv["b"] = 66; charsv["c"] = 67; 
charsv["d"] = 68; charsv["e"] = 69; charsv["f"] = 70; charsv["g"] = 71; 
charsv["h"] = 72; charsv["i"] = 73; charsv["j"] = 74; charsv["k"] = 75; 
charsv["l"] = 76; charsv["m"] = 77; charsv["n"] = 78; charsv["o"] = 79; 
charsv["p"] = 80; charsv["q"] = 81; charsv["r"] = 82; charsv["s"] = 83;  
charsv["t"] = 84; charsv["u"] = 85; charsv["v"] = 86; charsv["w"] = 87; 
charsv["x"] = 88; charsv["y"] = 89; charsv["z"] = 90; charsv["{"] = 91; 
charsv["|"] = 92; charsv["}"] = 93; charsv["~"] = 94; charsv["•"] = 99; 
charsv["š"] = 104; charsv["œ"] = 106;

the result should be: 33,65,34,66,35,67

Use split

and pass an empty string as a parameter

var text = "asdfghj";
var arr = text.split(""); // returns ["a", "s", "d", "f", "g", "h", "j"]

Then to convert each character to char code you can use map

for that



arr.map(function (char) { return char.charCodeAt(0); }); 
// returns [97, 115, 100, 102, 103, 104, 106]

EDIT: I noticed that your array charsv

does not map every character to ASCII code. However, even in this case, you can usemap 

arr.map(function (char) { return charsv[char]; }); 
// returns [65, 83, 68, 70, 71, 72, 74]

split

string and iterate with keys charsv

.
