我需要帮助将数字转换为单词[重复]

Question

我需要将数字更改为 1=A,2=B 之类的单词。当我输入类似12 的输入时，结果应该是AB，如果只在P 标签内输入2 结果必须是B。

<input type="text" id="nums">
<button id="btn"></button>
<p id="words"></p>

<script type="text/javascript">

    script here...

</script>

Answer 1

<input type="text" id="nums">
        <button id="btn" onclick="run()">run</button>
        <p id="words"></p>
        <script>
        function run(){

            var alfa='abcdefghijklmnopqrstuvwxyz';
            var alfa_array = alfa.split(""); //this creates an array which contain whole characters 
            var num=document.getElementById("nums").value;
            var number_array = num.split(""); //this creates an array which contain whole numbers in input

//then you can go through each number inside number_array and use that number as key in alfa_array.this gives you matching character for each number.then join all characters together.

            var result='';
            for(var i in number_array){            
            result+=alfa_array[parseInt(number_array[i])-1];
            }

        document.getElementById("words").html=result;
        }
        </script>

这样就可以了。
