jQuery – 如何计算具有rowspan属性的表行

嗨,我正在动态地创建一个表结构.当我单击一个包时,我将子行插入到表中,并添加了一个具有子值计数的rowspan值.现在我必须编号行我使用的行的索引,但是当有行跨度时应该考虑整行,因为1,下一个数字必须是2.当我单击删除时,我需要删除所有行跨行的子行.
这是一个我已经实现的代码,

var rowspans;
  var servicecount;
  var cnt;
  var ser = [];
  var refForEmployee = new Firebase("https://kekranmekrandubai.firebaseio.com/package");

  refForEmployee.on("value",function(snapshot) {
    var data = snapshot.val();
    var list = [];

    for (var key in data) {
      if (data.hasOwnProperty(key)) {
        name = data[key].image ? data[key].image : '';
        emp_name = data[key].package_name ? data[key].package_name : '';
        service = data[key].service ? data[key].service : '';
        servicecount = service.length;

        console.log("service data");
        console.log(service);
        console.log(servicecount);
        if (name.trim().length > 0) {
          list.push({
            image: name,emp_name: emp_name,services: service
          })
        }
      }
    }
    // refresh the UI
    refreshUI(list);


  });
  function refreshUI(list) {
    var lis = '';
    for (var i = 0; i < list.length; i++) {
      var empname = list[i].emp_name;
      var serc = [];
      serc = list[i].services;
      lis += '<div class="outlining"><div class="customize"><img class="employeeimages" src="' + list[i].image + '"></img><img src="img/bookingemployeeid.png" class="employee_id_display"><p class="firstname">' + list[i].emp_name + '<p class="lastname">Last name</p><p class="emps_id">1001</p><p class="arrays">' + serc + '</p></div></div>';

    };

    document.querySelector('#employee_list').innerHTML = lis;
  };
  $('body').on('click','.employeeimages',function() {
    var name = $(this).closest('.customize').find('.firstname').text();
    var service = [];
    service = $(this).closest('.customize').find('.arrays').text();
    console.log(service);

    //var myString = "Mr. Jack Adams";
    // Create a variable to contain the array
    var mySplitResult;
    // Use the string.split function to split the string
    mySplitResult = service.split(",");
    for (i = 0; i < mySplitResult.length; i++) {

      console.log(mySplitResult[i]);
      $("#booktable").append('<tr><td><div class="maindiv"><div class="productdiv"><p class="select_product">Select Items</p></div><div class="employeediv"><p>' + mySplitResult[i] + '</p></div><div class="pricediv">Price</div></div></td></tr>');

    }
    rowspans = mySplitResult.length;
    get_values(name,table_selected_index);

    $(".select_employee_div").css("display","none");

  });
  //booking main table
  //add row to booking table
  $(".useradd").click(function() {
    var rows = $('#booktable tr').length;
    var rowcount = rows + 1;

    $("#booktable").append('<tr><td id=' + rowcount + ' class="f">' + rowcount + '</td><td><div class="maindiv"><div class="productdiv"><p class="select_product">Select Items</p></div><div class="employeediv"><input type="button" class="select_employee" value="Select Employee"></div><div class="pricediv">Price</div><div class="actiondiv"><input type="button" value="x" class="remove"/></div></div></td></tr>');
  });

  //remove row and dynamically changing the index value of the removed row

  $("body").on("click",".remove",function(event) {
    event.preventDefault();
    var table = 'booktable';
    var row = $(this).closest('tr');

    setTimeout(function() { // Simulating ajax
      var siblings = row.siblings();
      row.remove();
      siblings.each(function(index) {
        $(this).children().first().text(index + 1);
      });
    },100);
  });

  $('#booktable').on('click','.select_employee',function() {
    $(".select_employee_div").css("display","block");
    var indexOfTheChangedRow = $(this).closest("tr").index();
    table_selected_index = indexOfTheChangedRow;

  });

  function get_values(val,rowIndex) {
    console.log("inside get_values function");

    console.log(val);

    $('#booktable tr:eq(' + rowIndex + ')').find(".select_employee").val(val);
    $('#booktable tr:eq(' + rowIndex + ')').find(".f").attr("rowspan",rowspans + 1)

  };

这是我需要的表结构




这是一个我已经实现的小提琴演示.我很惊讶改变行索引并删除action.Fiddle Demo请帮助我的代码.先谢谢你.

解决方法

您可以使用下面的代码来删除rowspan上的行,再重新输入剩余的行：

$('body').on('click','.remove',function(e) {
    e.preventDefault();
    var row=$(this).closest('tr');
    var rowspan=parseInt(row.children().first().attr('rowspan'));

    //remove row
    if (isNaN(rowspan)) {
        row.remove();
    } else {
        $('#booktable tr').slice(row.index(),row.index() + rowspan).remove();
    }


    //reindex
    var newIndex = 0;
    $('#booktable tr').each(function(i) {
        if ($(this).children().first().attr('id') !== undefined) {
            newIndex++;
            $(this).children().first().text(newIndex);
        }
    });
});
