如何在charCodeAt中记录多个字符

Question

对于下面的代码，它显然只会记录＆＃34; m＆＃34;在“＆＃34; man＆＃34;因为＆＃34; 0＆＃34;。如何记录所有三个字母？

var userChoice = prompt("let me encode something!");
var userChoice = (userChoice.charCodeAt(0) );
console.log (userChoice);

Answer 1

使用普通循环（向后兼容旧版浏览器）循环遍历userChoice

中的所有字符

var userChoice = prompt("let me encode something!");
for (var i = 0; i < userChoice.length; i++) {
  console.log (userChoice.charCodeAt(i));
}

Answer 2

怎么回事？

var userChoice = prompt("let me encode something!");
for (i = 0; i < userChoice.length; i++) {
    console.log(userChoice.charAt(i));
}


var userChoice = prompt("let me encode something!");
for (i = 0; i < userChoice.length; i++) {
    console.log(userChoice.charCodeAt(i));
}
