Question

#dialog-form包含两个单选按钮。从下拉对话框中选择“奥迪”值时，将出现一个表格。选择“是”并单击“保存”时，我希望将yes值作为新td附加到我们选择值的行，但此脚本将附加到所有行。

我也尝试使用$.closest tr，但这对我没用。

$(document).ready(function() {
    $("#dialog-form").dialog({
        autoOpen: false,
        modal: true,
        buttons: {
            "Save": addUser,
            Cancel: function() {
                $("#dialog-form").dialog( "close" );
            }
        }
    });
    $(".d1").on('change', function() {
        if ($(this).val() == 'audi') {
            $("#dialog-form").dialog("open");
        }
    });

    function addUser(){
        var selected = $("#dialog-form input[type='radio']:checked");
        
        if(selected.length > 0 && selected.val() == "Yes") {
            $('.mainTable tr').append("<td>" + selected.val() + "</td>");
            $("#dialog-form").dialog("close");
        }
    }
});

Answer 2

您可以将所选选项分配给变量，然后选择最近的＆＃34; tr＆＃34;并追加新的＆＃34; td＆＃34;进入它。

**var that = '';**
  $("#dialog-form").dialog({
        autoOpen: false,
        modal: true,
        buttons: {
           "Save": addUser,
        Cancel: function() {
          $("#dialog-form").dialog( "close" );
        }
      }
            });
   $(".d1").on('change', function() {
   if ($(this).val() == 'audi') {
            **that = $(this);**
             $("#dialog-form").dialog("open");

                    }
                      }); 

    function addUser(){
    var selected = $("#dialog-form input[type='radio']:checked");

    if(selected.length > 0 && selected.val()=="Yes"){


        **that.closest("tr").append("<td>" + selected.val() + "</td>");**
        $("#dialog-form").dialog("close");
    }
    }

  $(document).ready(function() {
  var selectElement;
  $("#dialog-form").dialog({
        autoOpen: false,
        modal: true,
        buttons: {
        Save: function() {
          var selected = $("#dialog-form input[type='radio']:checked");
          if(selected.length > 0 && selected.val()=="Yes"){
              selectElement.closest("tr").append("<td>" + selected.val() + "</td>");
          }
          $("#dialog-form").dialog( "close" );
        },
        Cancel: function() {
          $("#dialog-form").dialog( "close" );
        }
      }
            });
   $(".d1").on('change', function() {
      selectElement = $(this);
   		if ($(this).val() == 'audi') {
      		$("#dialog-form").dialog("open");
      }
   }); 

    function addUser(){
