如何使用用户输入的文本值追加一行动态添加的行？

Question

我有一个输入字段和一个引导模式框，我想将值附加到动态添加的行中，

例如，如果我单击添加行并单击输入字段打开弹出窗口并输入一些值，例如“Joe”，每当我单击添加行时，该值 (Joe) 会附加到每一行。

如果我想编辑一行数据只想更改的行，例如现在我只需添加一行并输入一些文本（此处为一些文本），然后我添加 4 行相同的文本（此处为一些文本) 将附加到 4 行，然后如果我编辑第 3 行输入文本，我只想更改第 3 行文本。不适用于所有行..

我希望我的问题得到理解。

这里是例子..

Answer 2

主要问题在这一行：$("#acc_narrat0").val($("#cash_text:first").val()) 它总是指第一个元素。要解决此问题，您可以设置一个变量，该变量在聚焦后引用输入。

此外，您可以使用hide.bs.modal 事件在模态文本区域关闭后对其进行清理。您可以shown.bs.modal 将 textarea 集中在显示上。

$(document).ready(function() {
  let inputElment = null;
  $("table").on("focus", "input[type='text']", function() {
    inputElment = jQuery(this);
  });

  $('#narratModal').on('hide.bs.modal', function() {
    $('#narratModal textarea').val("");
  });

  $('#narratModal').on('shown.bs.modal', function() {
    $('#narratModal textarea').focus();
  });


  $("#ok_button").on("click", function() {
    inputElment.val($("#cash_text:first").val());
  });

  $("#add_Row").on("click", function() {
    var counter = 0;
    var idVal = $('#tab_logic tr:last').find('td:first').html();
    var matches = idVal.match(/\d+/g);
    if (matches != null) {
      counter = Number(matches) + counter + 1;
    }
    var newRow = $("<tr>");
    var cols = "";

    cols += '<td><input value="' + $("#cash_text:first").val() + '" type="text" class="form-control required price" name="narr" placeholder="Enter your text here" id="acc_narrat' + counter + '" data-toggle="modal" data-target="#narratModal" onchange="unname(this.id, this.value)"/></td>'

    cols += '<td><button type="button" class="adRow ibtnDel" style="width:70%;">x</button></a></td>';

    newRow.append(cols);


    var defVal = $("select[name=acctname]").find(":selected").val();
    if (defVal) {
      $("select[name=accountName]").find(`option[value=${defVal}]`).hide();
    }
    $("table.order-list").append(newRow);
    setValCashVal('accountName'.concat(counter));
    bindScript();
    counter++;

  });
  $("table.order-list").on("click", ".ibtnDel", function(_event) {
    $(this).closest("tr").remove();
    if ($("#tab_logic tbody tr").length == 1)
      $("#cash_text:first").val('');
    evaluateTotal();

  });
});

/* Apend value to all row */
$("#ok_button").on('click', function() {
  let val = $("#cash_text").val();
  $("#pay_narrat, #acc_narrat").val(val);
});
