After converting a string input into a split array, I now need to convert that split array into ASCII for evaluation. Can someone provide guidance on how to do this?
After converting a string input into a split array, I now need to convert that split array into ASCII for evaluation. Can someone provide guidance on how to do this?
Technically, a string input is equivalent to an array of characters.
Here are the steps to achieve this:
characterCodes = [];
for (var i = 0; i < userInput.length; i ++)
characterCodes.push(userInput[i].charCodeAt(0));
Is it supposed to be like this?
let websiteUrl = document.URL;
let asciiValues = websiteUrl.split('').map(function(item){
return item.charCodeAt(0);
});
let formattedAsciiValues = asciiValues.map(function(value, index){
return '#'+index+'=0x'+value.toString(16)+' ('+String.fromCharCode(value)+')';
}).join('\n');
alert('Original URL='+ websiteUrl+'\nASCII codes:\n'+formattedAsciiValues);
/* output:
Original URL=http://localhost/webworks/ghost.html
ASCII codes:
#0=0x68 (h)
#1=0x74 (t)
#2=0x74 (t)
#3=0x70 (p)

// [67, 111, 100, 105, 110, 103, 32, 105, 115, 32, 102, 117, 110]In this code snippet, an array is initialized to match the length of a given string. Each character in the string is then mapped to its corresponding Unicode value:
let str = 'ABCD1234560';
let arr = Array(str.length).fill().map((_, i) => str.charCodeAt(i));
console.log(arr);This method allows for easy extraction of a subset of characters from the string. For instance, only taking the first 4 characters:
let str = 'ABCD1234560';
let arr = Array(4).fill().map((_, i) => str.charCodeAt(i));
console.log(arr);Alternatively, you can iterate directly over the string and push each character's Unicode value into an array:
let str = 'ABCD1234560';
let arr = [];
for (let i = 0; i < str.length; i++)
arr.push(str.charCodeAt(i));
