Question

我已经创建了一个简单的数据表，其中包括以下操作（编辑，删除）。

我已在模式中将确认删除添加到删除按钮。

问题是，当用户单击“是” 时，这表示删除，该行一直显示并且未被删除。这是模式的HTML代码：

<div id="myModal" class="modal fade">
  <div class="modal-dialog modal-confirm">
    <div class="modal-content">
      <div class="modal-header">
        <div class="icon-box">
          <i class="material-icons">&#xE5CD;</i>
        </div>
        <h4 class="modal-title">Are you sure?</h4>
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      </div>
      <div class="modal-body">
        <p>Do you really want to delete these records? This process cannot be undone.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-info" data-dismiss="modal">Cancel</button>
        <button type="button" class="btn btn-danger" id="btnDelteYes">Delete</button>
      </div>
    </div>
  </div>
</div>

这是删除按钮的jQuery代码：

$(document).ready(function() {
  $("form").submit(function(e) {
    e.preventDefault();
    var name = $("input[name='name']").val();
    var email = $("input[name='email']").val();

    $(".data-table tbody").append("<tr data-name='" + name + "' data-email='" + email + "'><td>" + name + "</td><td>" + email + "</td><td><button id='test5' class='btn btn-info btn-xs btn-edit'>Edit</button><button class='btn btn-danger btn-xs btnDelete' id='test6'>Delete</button></td></tr>");

    $("input[name='name']").val('');
    $("input[name='email']").val('');
  });
  $("body").on('click', '.btn.btnDelete', function() {
    var id = $(this).closest('tr').data('id');
    $('#myModal').data('id', id).modal('show');
  });


  $("body").on("click", function() {
    $("#btnDelteYes").parents("tr").remove();
    $('#myModal').modal('hide');
  });
});

我需要帮助来解决此问题并知道我在做什么错。任何帮助将不胜感激。

谢谢！

我对您的基础code做了以下更改（删除了一些与问题无关的代码）：

$(document).ready(function() {
  $("form").submit(function(e) {
    e.preventDefault();
    var name = $("input[name='name']").val();
    var email = $("input[name='email']").val();

    var trLen = $(".data-table").find("tr").length;

    $(".data-table tbody").append("<tr data-name='" + name + "' data-email='" + email + "'><td>" + name + "</td><td>" + email + "</td><td><button id='edit" + trLen + "' class='btn btn-info btn-xs btn-edit'>Edit</button><button class='btn btn-danger btn-xs btnDelete' id='delete" + trLen + "'>Delete</button></td></tr>");

    $("input[name='name']").val('');
    $("input[name='email']").val('');
  });
  
  $("body").on('click', '.btn.btnDelete', function() {
    var id = $(this).attr('id');
    $('#myModal').data('id', id).modal('show');
  });


  $("body").on('click', '#btnDelteYes', function() {
    var id = $('#myModal').data('id');
    $('#' + id).parents("tr").remove();
    $('#myModal').modal('hide');
  });
});

首先，您所有的按钮ID均相同，并且必须唯一。

第二，当您单击删除按钮时，id目标错误。因此将var id = $(this).closest('tr').data('id')更改为var id = $(this).attr('id');

第三，当您单击确认删除按钮时，尽管您正确地获得了id，但是您并未使用它。因此将$('#btnDelteYes').parents("tr").remove();更改为$('#' + id).parents("tr").remove();。

使用模式确认删除行
