用HTML的emoji unicode替换输入值

Question

我有以下聊天应用，我想替换包含'&#1F600;'的任何字符串 if ($('#m').val().match(/(\:\))/g)) { $('#m').val() = $('#m').val().replace(/(\:\))/g, '&#1F600;') } ，以便它变成表情符号

到目前为止我所做的并不奏效。我相信我的正则表达式是正确的。

            $('#m').val('');
            return false;

        socket.on('chat message', function (msg) {
            $('#messages').append($('<li>').text(msg));
        });

    });
