使用Bootstrap 3模态框确认删除

Question

我需要使用Bootstrap 3模态框（是/否）来确认删除。我该如何创建？

HTML代码：

<form action="blah" method="POST">
    <button class='btn' type="submit" name="remove_levels" value="delete">
        <span class="fa fa-times"></span> Delete
    </button>
</form>

Answer 1

你需要在HTML中使用模态框。当单击删除按钮时，它会弹出模态框。还很重要的是要防止该按钮的点击提交表单。当确认被点击时，表单将被提交。

   

 $('button[name="remove_levels"]').on('click', function(e) {
      var $form = $(this).closest('form');
      e.preventDefault();
      $('#confirm').modal({
          backdrop: 'static',
          keyboard: false
      })
      .on('click', '#delete', function(e) {
          $form.trigger('submit');
        });
      $("#cancel").on('click',function(e){
       e.preventDefault();
       $('#confirm').modal.model('hide');
      });
    });

<link href="http://getbootstrap.com/2.3.2/assets/css/bootstrap.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://getbootstrap.com/2.3.2/assets/js/bootstrap.js"></script>
<form action="#" method="POST">
  <button class='btn btn-danger btn-xs' type="submit" name="remove_levels" value="delete"><span class="fa fa-times"></span> delete</button>
</form>

<div id="confirm" class="modal">
  <div class="modal-body">
    Are you sure?
  </div>
  <div class="modal-footer">
    <button type="button" data-dismiss="modal" class="btn btn-primary" id="delete">Delete</button>
    <button type="button" data-dismiss="modal" class="btn">Cancel</button>
  </div>
</div>

这个很好用，但有一个需要注意的地方：如果我先点击取消，再点击删除，然后再次点击删除，在我的情况下，提交会被发送两次。它应该只提交一次。 - Khrys

@Khrys，你应该验证是否包含了 e.preventDefault()。 - Nathan Koop

这里有一个问题。请注意，如果您正在使用此功能来确认删除某个带有ID的内容。问题在于，如果您点击“取消”，事件仍将附加到模态框上。如果您之后再点击另一个要删除的内容，它将同时删除两个。 - Pedro Lourenço

针对之前评论中提到的问题，Pedro指出$('#confirm').unbind()可以帮助解除绑定的事件。 - shivg

@NigelAngel 如果我点击“取消”按钮的次数为n，则.one('click', '#delete', function(e) {})调用n次。如果我在前三次点击“取消”按钮，然后点击“删除”按钮，我的.one({})会执行4次。请检查。 - Chinmay235

Answer 2

您可以使用Bootbox对话框。

$(document).ready(function() {

  $('#btnDelete').click(function() {
    bootbox.confirm("Are you sure want to delete?", function(result) {
      alert("Confirm result: " + result);
    });
  });
});

今天我遇到了同样的问题。这是我的解决方案（我认为更好更简单）：

<!-- Modal dialog -->
<div class="modal fade" id="frmPrenotazione" tabindex="-1">
    <!-- CUTTED -->
    <div id="step1" class="modal-footer">
      <button type="button" class="glyphicon glyphicon-erase btn btn-default" id="btnDelete"> Delete</button>
    </div>
</div>

<!-- Modal confirm -->
<div class="modal" id="confirmModal" style="display: none; z-index: 1050;">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body" id="confirmMessage">
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" id="confirmOk">Ok</button>
                <button type="button" class="btn btn-default" id="confirmCancel">Cancel</button>
            </div>
        </div>
    </div>
</div>

在我的 .js 文件中：

$('#btnDelete').on('click', function(e){
    confirmDialog(YOUR_MESSAGE_STRING_CONST, function(){
        //My code to delete
    });
});

function confirmDialog(message, onConfirm){
    var fClose = function(){
        modal.modal("hide");
    };
    var modal = $("#confirmModal");
    modal.modal("show");
    $("#confirmMessage").empty().append(message);
    $("#confirmOk").unbind().one('click', onConfirm).one('click', fClose);
    $("#confirmCancel").unbind().one("click", fClose);
}

在使用 one 函数之前，使用 unbind 函数可以防止下次打开对话框时调用删除函数。

我希望这能有所帮助。

以下是一个完整的示例：

var YOUR_MESSAGE_STRING_CONST = "Your confirm message?";
      $('#btnDelete').on('click', function(e){
      confirmDialog(YOUR_MESSAGE_STRING_CONST, function(){
       //My code to delete
          console.log("deleted!");
      });
     });

        function confirmDialog(message, onConfirm){
         var fClose = function(){
         modal.modal("hide");
         };
         var modal = $("#confirmModal");
         modal.modal("show");
         $("#confirmMessage").empty().append(message);
         $("#confirmOk").unbind().one('click', onConfirm).one('click', fClose);
         $("#confirmCancel").unbind().one("click", fClose);
        }

      <div id="step1" class="modal-footer">
    <button type="button" class="glyphicon glyphicon-erase btn btn-default" id="btnDelete"> Delete</button>
  </div>
</div>

  <!-- Modal confirm -->
<div class="modal" id="confirmModal" style="display: none; z-index: 1050;">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-body" id="confirmMessage">

            <button type="button" class="btn btn-default" id="confirmCancel">Cancel</button>

使用模态框的简单方法是使用eModal！

来自github的示例：

1. 链接到eModal.js <script src="//rawgit.com/saribe/eModal/master/dist/eModal.min.js"></script>

    var options = {
            message: "The famouse question?",
            title: 'Header title',
            size: 'sm',
            callback: function(result) { result ? doActionTrue(result) :    doActionFalse(); },
            subtitle: 'smaller text header',
            label: "True"   // use the possitive lable as key
            //...
        };
                     
    eModal.confirm(options);

使用id="confirmation"在HTML中创建模态对话框，并使用showConfirmation函数。

同时请记住，在隐藏模态对话框后，您应该取消绑定(cancel和success按钮)。如果您不这样做，将会出现双重绑定的情况。 例如：如果您打开对话框一次，按下“取消”，然后再次打开对话框并按下“确定”，您将获得两个成功回调的执行。

showConfirmation = function(title, message, success, cancel) {
    title = title ? title : 'Are you sure?';
    var modal = $("#confirmation");
    modal.find(".modal-title").html(title).end()
        .find(".modal-body").html(message).end()
        .modal({ backdrop: 'static', keyboard: false })
        .on('hidden.bs.modal', function () {
            modal.unbind();
        });
    if (success) {
        modal.one('click', '.modal-footer .btn-primary', success);
    }
    if (cancel) {
        modal.one('click', '.modal-header .close, .modal-footer .btn-default', cancel);
    }
};

// bind confirmation dialog on delete buttons
$(document).on("click", ".delete-event, .delete-all-event", function(event){
    event.preventDefault();
    var self = $(this);
    var url = $(this).data('url');
    var success = function(){
        alert('window.location.href=url');
    }
    var cancel = function(){
        alert('Cancel');
    };
    if (self.data('confirmation')) {
        var title = self.data('confirmation-title') ? self.data('confirmation-title') : undefined;
        var message = self.data('confirmation');
        showConfirmation(title, message, success, cancel);
    } else {
        success();
    }
});

$('button[name="remove_levels"]').on('click', function(e) {
  var $form = $(this).closest('form');
    e.preventDefault();
    $('#confirm').modal({
    backdrop: 'static',
    keyboard: false
  })
  .on('click', '#delete', function(e) {
    $form.trigger('submit');
  });
  $("#cancel").on('click',function(e){
    e.preventDefault();
    $('#confirm').modal.model('hide');
  });
});

<link href="http://getbootstrap.com/2.3.2/assets/css/bootstrap.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://getbootstrap.com/2.3.2/assets/js/bootstrap.js"></script>

<form action="#" method="POST">
  <button class='btn btn-danger btn-xs' type="submit" name="remove_levels" value="delete"><span class="fa fa-times"></span> delete</button>
</form>
<div id="confirm" class="modal">
  <div class="modal-body">
    Are you sure?
  </div>
  <div class="modal-footer">
    <button type="button" data-dismiss="modal" class="btn btn-primary" id="delete">Delete</button>
    <button type="button" data-dismiss="modal" class="btn">Cancel</button>
  </div>
</div>

这段代码无法正常工作，需要进行以下更改：

1. 需要在取消按钮上定义id="cancel"

    <button type="button" data-dismiss="modal" id="cancel" class="btn">取消</button>
   

2. 取消点击事件更改如下

    $('button[name="remove_levels"]').on('click', function(e) {
      var $form = $(this).closest('form');
      e.preventDefault();
      $('#confirm').modal({
          backdrop: 'static',
          keyboard: false
      })
      .on('click', '#delete', function(e) {
          $form.trigger('submit');
        })
      .on('click','#cancel', function(e){
       e.preventDefault();
       $('#confirm').modal.model('hide');
      });
    });

以下解决方案比bootbox.js更好，因为：

• 它可以做到bootbox.js所能做的一切；
• 使用语法更简单；
• 它允许您通过“error”、“warning”或“info”优雅地控制消息的颜色；
• Bootbox有986行代码，而我的只有110行。

digimango.messagebox.js:

const dialogTemplate = '\
    <div class ="modal" id="digimango_messageBox" role="dialog">\
        <div class ="modal-dialog">\
            <div class ="modal-content">\
                <div class ="modal-body">\
                    <p class ="text-success" id="digimango_messageBoxMessage">Some text in the modal.</p>\
                    <p><textarea id="digimango_messageBoxTextArea" cols="70" rows="5"></textarea></p>\
                </div>\
                <div class ="modal-footer">\
