用表情符号替换字符串

给定是具有表示表情符号的代码的输入字段.我现在想用相应的表情符号替换此代码.

我的想法是用unicode替换值,但这对我的输入不起作用.只有当我将表情符号本身复制到代码中时,替换才有效.

例:

给定代码:[e-1f60e],
转换:&＃x1f60e;,
应该是:

我的问题:如何将给定的代码转换为Javascript中的表情符号？

$("#tauschen").click(function() {
  $('#blub').val(function(index, value) {
    return value.replace('[e-1f60e]', '&＃x1f60e;'); // Doesn't work
  });
});

$("#tauschen2").click(function() {
  $('#blub2').val(function(index, value) {
    return value.replace('[e-1f60e]', ''); // Works - but how to convert the given string to an emoji?!
  });
});

  Given are strings in an imout field like these, representing an emoji: [e-1f60e] 


 Now I want to display them "live" as emojis, instead of only the code: &＃x1f60e;

function convertEmoji(str) {
  return str.replace(/\[e-([0-9a-fA-F]+)\]/g, (match, hex) =>
    String.fromCodePoint(Number.parseInt(hex, 16))
  );
}

console.log(convertEmoji('[e-1f60e]')); //
