　　在JavaScript中，将Unicode值转字符的方法：

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8">

    <meta http-equiv="X-UA-Compatible" content="IE=edge">

    <title>JavaScript39</title>

    <link rel="stylesheet" href="">

</head>

<body>

    <input type="text" id="input1">

    <p id="demo2"></p>

    <button onclick="fromCharCode()">Unicode转换为字符串</button>

    <script>

        function groupArray(str){

            var result = new Array();

            for (var i = 0; i < str.length/2; i++) {

                var aa = str.slice(i*2, (i+1)*2);

                result.push(aa);

            }

            return result;

        }

        function fromCharCode(){

            var m =document.getElementById("input1").value;    //获取输入框的值

            console.log(m);

            var strArray = groupArray(m);    //将输入框的值进行分组存放到数组里

            console.log(strArray);

            var charStr = "";

            for (var i = 0; i < strArray.length; i++) {

                var istr = strArray[i];

                charStr = charStr.concat(String.fromCharCode(istr));    //将数组里的Unicode值转成字符串并连接起来

            }

            console.log(charStr);

            document.getElementById("demo2").innerHTML = charStr;        //将连接起来的值

        }

    </script>

</body>

</html>
