如何在mvc的编辑器模板中只插入唯一值

Question

我只想在我的编辑器模板中输入唯一的Machine_serial_no，用户可以通过浏览文件添加Machine_serial_no或者可以手动输入如下代码所示，我只是想确保用户不应允许两次输入相同的值。随时欢迎您提出建议 ..提前致谢..

Answer 1

我认为这是你想要验证的客户端

   $(function (){
            $('#partialViewtextbox_Id').change(function (){
              var partial = $('#partialViewtextbox_Id').val();
              var main = $('#maintextbox_Id').val();
                  if(partial == main)
        {
                alert("value already available");
        }

                });       

        });

Answer 2

假设您想在用户输入非唯一值时立即提醒用户，那么您需要处理文本框的 .change() 事件，并且由于文本框是动态添加的，因此您需要使用事件委托

$('#td_serial').on('change', '.serial1', function() {
  var isvalid = true;
  var inputs = $('.serial1').not($(this));
  var text = $(this).val();
  $.each(inputs, function(index, item) {
    if ($(this).val() && $(this).val() === text) {
      isvalid = false;
      return false;
    }
  });
  if (!isvalid) {
    alert('not unique!');
  }
});

请注意 alert('not unique!') 仅用于测试目的 - 不清楚您希望如何通知用户 - 例如包含一个 div 和一条错误消息，您可以 show/hide 根据需要

接下来你的部分包括 @Html.ValidationMessageFor(x => x.Machine_serial_no) 表明你有验证属性。为了对动态创建的元素进行客户端验证，您需要在添加新元素时重新解析验证器。将您的脚本修改为

for (i = 0; i < count; i++) {
  $.ajax({
    type: 'GET',
    data: { mid: $('#machineTypes_MTId').val(), modelName: $('#searchid').val(), modelId: $('#searchValue').val() },
    url: '@Url.Action("AddMachineSerial","Import")',
    success: function (response) {
      $('#ShowModel').show();
      $('#td_serial').prepend(response);
      $('#count').val(0);
      // Reparse the validator
      $('form').data('validator', null);
      $.validator.unobtrusive.parse(form);
    }
  });
}

旁注 - 考虑对此进行修改，以便仅在所有 ajax 调用完成后才重新解析

另请注意，您应该只有一个 @Html.ValidationSummary(true)（您目前正在为每个部分添加一个）并且您需要从部分中删除脚本 - 您应该只在主视图
