Question

我有多个具有相同名称的输入，我只想选择一个选项。

但是如果未选中该复选框，则此选项应为null。当用户选择复选框选择一个选项然后取消选中时，我遇到了问题。该选项仍处于选中状态。当我取消勾选复选框时，我想删除所有带有该名称的选项。

所以我尝试$('input[name="customerUIBranch"]').val(null);，但它没有帮助

$('#hasCustomerUITab').hide();


$('#customerUI').change(function () {
        if ($(this).is(":checked")) {
            $('#hasCustomerUITab').show();
        }
        else {
            $('#hasCustomerUITab').hide();
            $('input[name="customerUIBranch"]').val(null);
        }
    });
   
   $('#submit').click(function() {
    console.log($('input[name="customerUIBranch"]').val());
   
   });

试试这个

$('#hasCustomerUITab').hide();


$('#customerUI').change(function () {
        if ($(this).is(":checked")) {
            $('#hasCustomerUITab').show();
        }
        else {
            $('#hasCustomerUITab').hide();
            //this
            $('input[name="customerUIBranch"]').prop('checked', false);
            //or
            $('input[name="customerUIBranch"]').attr("checked", false);
        }
    });

   $('#submit').click(function() {
    console.log($('input[name="customerUIBranch"]').val());

$('#hasCustomerUITab').hide();


$('#customerUI').change(function () {
        if ($(this).is(":checked")) {
            $('#hasCustomerUITab').show();
        }
        else {

            $('input[name=customerUIBranch]').removeAttr('checked');
        }

   });

Answer 3

你应该改变这一行

$('input[name="customerUIBranch"]').val(null);

这一行

$('input[name="customerUIBranch"]').prop('checked', false);

Answer 4

试试这个：

<script>
  jQuery('#hasCustomerUITab').hide();
  $('#customerUI').change(function () {
  var ischecked= $(this).is(':checked');
  if(ischecked){
    $('#hasCustomerUITab').show();
  }
  else {
    $('#hasCustomerUITab').hide();
    $('input[name="customerUIBranch"]').val(null);
    $(":radio").removeAttr("checked");
  }
});

$('#submit').click(function() {
  console.log($('input[name="customerUIBranch"]').val()); 
});

删除所有选定的选项
