从复选框显示多个数据

Question

如何从复选框获取多个数据到另一个模式？如果我单击一个按钮，则会出现一个带有一些数据的引导模式。数据有复选框。我想在表格中的另一个模式上打印选定的数据。我正在尝试推送值，但它只是打印复选框值，我想打印 name 和 connected to。

我的代码

$(document).ready(function() {
        $("#checkBtn2").click(function() {
            var favorite = [];
            $.each($("input[name='case']:checked"), function() {
                favorite.push($(this).val());
            });
            $('#myModal2').modal('show').on('shown.bs.modal', function() {
                $("#checkid").html(favorite.join(", "));
            });
        });
    });

Answer 1

你可以得到最接近checkbox checked 的tr 并将其作为json object 提供给favorite 变量。然后您可以使用for-loop 在模态中检索它。这样会更有条理。

$(document).ready(function() {
        $("#checkBtn2").click(function() {
            var favorite = [];
            $.each($("input[name='case']:checked"), function() {
                var tr = $(this).closest('tr');
                var data1 = $(tr).find('td').eq(0).text();
                var data2 = $(tr).find('td').eq(1).text();
                var data = {data1: data1, data2: data2};
                favorite.push(data);
            });
            $('#myModal2').modal('show').on('shown.bs.modal', function() {
                $("#checkid").html("");
                for(var i=0;i < favorite.length; i++){
                  $("#checkid").append('<div>'+favorite[i].data1 +',' + favorite[i].data2 +'</div>');
                }
            });
        });
    });

Answer 2

试试：

$(document).ready(function() {
  $("#checkBtn2").click(function() {
    var favorite = [];
    $.each($("input[name='case']:checked"), function() {
      var elem = $(this);
      var parent = elem.parents("tr:first");
      var name = parent.find("td:first").text();
      var connectedTo = parent.find("td:eq(1)").text();
      favorite.push(name + ":" + connectedTo);
    });
    $('#myModal2').modal('show').on('shown.bs.modal', function() {
      $("#checkid").html(favorite.join(", "));
    });
  });
});

您的代码的问题是输入在 html 中没有“connectedTo”数据。要么从 td 元素中获取它，要么修改 html 以便您可以在输入的数据属性中存储相同的数据。
