<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script>
        var reg = new RegExp("\w{6,12}");
        var reg2 = /^\w{6,12}$/;

        // alert(reg)
        // alert(reg2)

        var username = "zhangsan";
        var flag = reg2.test(username);
        alert(flag);

    </script>
</head>
<body>
