本文介绍了一个HTML页面中的输入字段验证功能，包括限制中文输入，并实现手机号的严格校验。

<html>
<head><title>Sample</title>
<meta http-eqquiv="content-type" content="text/html; charset=utf-8">
<script type="text/javascript">
    function checkinput(obj) {
        var value = obj.value;
        if (value.match(/[^\u3447-\uFA29]/ig)) {
            alert("此欄位只能輸入中!");
            obj.value = "";
            obj.focus();
        }
    }
</script>
</head>
<body>
<input type="text" onkeyup="checkinput(this)">
</body>
</html>

function checkMobileStrict(v) {
var yd = ['134', '135', '136', '137', '138', '139', '150', '151', '152', '157', '158', '159', '187', '188'];

var dx = ['133', '153', '180', '189']; 
var whole = []; whole = whole.concat(yd, lt, dx);
if (v == '') return 1; 
if (v.length != 11) { return 2; } 
if (isNaN(v)) { return 2; } 
  var phone_sect = v.substr(0, 3);
var find = false; 
var i = 0; 
for (i = 0; (i < whole.length); i++) 
{ if (phone_sect == whole[i]) { find = true; break; } } 
  if (find) return 0; else return 2;
  }
