在JavaScript中將字符轉換爲ASCII

Question

我首先獲取一個字符串輸入並將其更改爲拆分數組，然後我需要更改該拆分數組中的ASCII以進行評估。我怎麼做？

Answer 1

字符串輸入在技術上已經是一個字符數組。

你可以做以下

asciiKeys = []; 
for (var i = 0; i < string.length; i ++) 
    asciiKeys.push(string[i].charCodeAt(0)); 

Answer 2

這樣嗎？

var str= document.URL; 
var ascii= str.split('').map(function(itm){ 
    return itm.charCodeAt(0); 
}); 
var str2=ascii.map(function(itm, i){ 
    return '#'+i+'=0x'+itm.toString(16)+' ('+String.fromCharCode(itm)+')'; 
}).join('\n'); 


alert('original string='+ str+'\nascii codes:\n'+str2);
