如何使用mask插件验证我们的邮政编码？

Question

我不想让第一个字母全部为零来邮编。

$('#zipcode').mask("Y0000", { 
 
    'clearIfNotMatch': true, 
 
    'translation': { 
 
    Y: { 
 
     pattern: /[1-9]/ 
 
    } 
 
    } 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.10/jquery.mask.js"></script> 
 

 
<input name="zipcode" id="zipcode" class="form-control" type="text" required>

动态口罩应帮助：

var options = { 
 
    'onKeyPress': function(cep, e, field, options){ 
 
    var masks = ['00000', '0000Z']; 
 
    mask = (cep == '0000') ? masks[1] : masks[0]; 
 
    $('#zipcode').mask(mask, options); 
 
    }, 
 
    'clearIfNotMatch': true, 
 
    'translation': { 
 
     'Z': { 
 
     pattern: /[1-9]/ 
 
     } 
 
    } 
 
}; 
 

 
$('#zipcode').mask("00000", options);
