Question

我有一个表单，其中包含基于一个下拉列表的一系列字段，以下输入字段需要更改其有效性。

一个示例，我通过以下方法对此进行设置：

$("#Identifier").attr("pattern", "[0-9]{11}");
$("#Identifier").attr("oninvalid", "setCustomValidity('Must be 11 digits.')");

然后依次显示：

<input type="text" pattern="[0-9]{11}" name="Identifier" id="Identifier" required="" oninvalid="setCustomValidity('Must be 11 digits.')">

但是，无论我何时输入该字段，它始终会在该字段上显示错误。

我不确定如何获得积极的结果或我缺少的东西。

这是我的完整代码：

<body>
<form id="form1" runat="server">
<div id="main-bg">
<table width="960" border="0" cellspacing="0" cellpadding="0">
  <tr>

    <td align="left" valign="top" class="style67">
    <div id="main"><div class="style9" style="width: 701px">

        <br />

        <br />
        <span class="auto-style1">
        <div id="main-title" class="style54" style="width: 475px">

    <% IF strWebCountry = "" Then
Response.Write("<input name=Submit type=submit value=""Maturity Instructions"" /></form></p>")  
        else

<script type="text/javascript">

});
</script>



<script type="text/javascript">
$('#Identifier').on('focus', function(){
   console.log($('#IdentifierSelect').val());
    $('#IdentifierSelect12').html('');
    if($('#IdentifierSelect').val()=="Belgian National Number"){
        $("#Identifier").attr("pattern", "[0-9]{11}");
        $("#Identifier").attr("oninvalid", "setCustomValidity('Must be 11 digits.')");
        $("#Identifier").attr("required");
    }
    });
</script>

提交时进行HTML验证-始终返回false
