javascript - Jquery - 需要使用选定的单词验证文本字段

Question

我需要验证使用以下值提交的输入文本:“PO BOX”、POBOX、“GPO BOX” 和 “GPOX”

如果有人在文本框中输入这些文字，请提醒他们“我们不会将产品运送到邮政信箱地址”。并删除整个文本。

我在下面构建了，

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').blur(function(){

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('PO BOX'),
$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('POBOX'), $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('GPO BOX'),

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('GPOX'),

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('po box'),

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('pobox'),

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('gpo box'),

$('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val() == $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val().match('gpox') {

          alert('We do not ship products to PO Box addresses');
          $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val('');
          $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').focus();
      }

  });     });

但问题是它只验证确切的单词，

我的意思是，如果添加 PO BOX 1145 和其他一些文本，它就不会验证。

尝试使用正则表达式。我不是正则表达式专家，但您只需要在字符串中查找包含“PO”后跟“BOX”的文本即可。

所以，这应该可以解决问题

var regex = new RegExp("PO");
var match = regex.exec($('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val());
if (match != null)
{
    alert('We do not ship products to PO Box addresses');
    $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').val('');
    $('#objCheckoutRegistration_PhysicalAddress_txtAddressLine1').focus();
}
