我有一张与数据库行关联的HTML表格。我想为每一行添加一个“删除行”链接,但是我希望在此之前先与用户确认。
是否可以使用Twitter Bootstrap模态框来实现这个功能?

对于这个任务,您可以使用已经可用的插件和Bootstrap扩展程序。或者您可以使用只有3行代码的自己的确认弹出窗口。请查看。
假设我们有这些链接(注意使用data-href
而不是href
)或按钮,我们希望进行删除确认:
<a href="#" data-href="delete.php?id=23" data-toggle="modal" data-target="#confirm-delete">Delete record #23</a>
<button class="btn btn-default" data-href="/delete.php?id=54" data-toggle="modal" data-target="#confirm-delete">
Delete record #54
</button>
在这里#confirm-delete
指向您HTML中的模态弹出式div。 它应该配置一个像这样的“确定”按钮:
<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
...
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<a class="btn btn-danger btn-ok">Delete</a>
</div>
</div>
</div>
</div>
现在,您只需要这个小 JavaScript 来使删除操作可确认:
$('#confirm-delete').on('show.bs.modal', function(e) {
$(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});
在show.bs.modal
事件中,删除按钮的href
被设置为具有相应记录ID的URL。

我意识到在某些情况下需要执行POST或DELETE请求而不是GET。这仍然非常简单,几乎没有太多的代码。使用以下方法查看下面的演示:
// Bind click to OK button within popup
$('#confirm-delete').on('click', '.btn-ok', function(e) {
var $modalDiv = $(e.delegateTarget);
var id = $(this).data('recordId');
$modalDiv.addClass('loading');
$.post('/api/record/' + id).then(function() {
$modalDiv.modal('hide').removeClass('loading');
});
});
// Bind to modal opening to set necessary data properties to be used to make request
$('#confirm-delete').on('show.bs.modal', function(e) {
var data = $(e.relatedTarget).data();
$('.title', this).text(data.recordTitle);
$('.btn-ok', this).data('recordId', data.recordId);
});
// Bind click to OK button within popup
$('#confirm-delete').on('click', '.btn-ok', function(e) {
var $modalDiv = $(e.delegateTarget);
var id = $(this).data('recordId');
$modalDiv.addClass('loading');
setTimeout(function() {
$modalDiv.modal('hide').removeClass('loading');
}, 1000);
// In reality would be something like this
// $modalDiv.addClass('loading');
// $.post('/api/record/' + id).then(function() {
// $modalDiv.modal('hide').removeClass('loading');
// });
});
// Bind to modal opening to set necessary data properties to be used to make request
$('#confirm-delete').on('show.bs.modal', function(e) {
var data = $(e.relatedTarget).data();
$('.title', this).text(data.recordTitle);
$('.btn-ok', this).data('recordId', data.recordId);
});

这里是我回答 Bootstrap 2.3 模态框问题时所做的原始代码版本。
$('#modal').on('show', function() {
var id = $(this).data('id'),
removeBtn = $(this).find('.danger');
removeBtn.attr('href', removeBtn.attr('href').replace(/(&|\?)ref=\d*/, '$1ref=' + id));
});
http://bootboxjs.com/ - 最新版适用于Bootstrap 3.0.0
最简单的示例:
bootbox.alert("Hello world!");
来自该网站:
该库公开了三种方法,旨在模仿它们本地的 JavaScript 等效方法。它们的确切方法签名是灵活的,因为每个方法都可以接受各种参数来自定义标签并指定默认值,但最常见的调用方式是这样的:
bootbox.alert(message, callback)
bootbox.prompt(message, callback)
bootbox.confirm(message, callback)
这是它在实际操作中的一小段代码(点击下面的“运行代码片段”):
$(function() {
bootbox.alert("Hello world!");
});

我知道这是一个非常老的问题,但是今天我想寻找一种更有效的处理Bootstrap模态框的方法。经过一些研究,我发现了比上面展示的解决方案更好的东西,可以在这个链接中找到:
http://www.petefreitag.com/item/809.cfm
首先加载jQuery。
$(document).ready(function() {
$('a[data-confirm]').click(function(ev) {
var href = $(this).attr('href');
if (!$('#dataConfirmModal').length) {
$('body').append('<div id="dataConfirmModal" class="modal" role="dialog" aria-labelledby="dataConfirmLabel" aria-hidden="true"><div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="dataConfirmLabel">Please Confirm</h3></div><div class="modal-body"></div><div class="modal-footer"><button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button><a class="btn btn-primary" id="dataConfirmOK">OK</a></div></div>');
}
$('#dataConfirmModal').find('.modal-body').text($(this).attr('data-confirm'));
$('#dataConfirmOK').attr('href', href);
$('#dataConfirmModal').modal({show:true});
return false;
});
});
然后只需向 href 提出任何问题/确认即可:
<a href="/any/url/delete.php?ref=ID" data-confirm="Are you sure you want to delete?">Delete</a>
通过这种方式,确认模态框更具普适性,因此可以轻松地在您网站的其他部分重复使用。
感谢@Jousby的解决方案,我也成功地让我的工作起来了,但我发现我必须改进他的Bootstrap模态标记一点,才能像官方示例演示的那样正确呈现。
所以,这是我对通用的confirm
函数进行修改后的版本,可以正常工作:
/* Generic Confirm func */
function confirm(heading, question, cancelButtonTxt, okButtonTxt, callback) {
var confirmModal =
$('<div class="modal fade">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<a class="close" data-dismiss="modal" >×</a>' +
'<h3>' + heading +'</h3>' +
'</div>' +
'<div class="modal-body">' +
'<p>' + question + '</p>' +
'</div>' +
'<div class="modal-footer">' +
'<a href="#!" class="btn" data-dismiss="modal">' +
cancelButtonTxt +
'</a>' +
'<a href="#!" id="okButton" class="btn btn-primary">' +
okButtonTxt +
'</a>' +
'</div>' +
'</div>' +
'</div>' +
'</div>');
confirmModal.find('#okButton').click(function(event) {
callback();
confirmModal.modal('hide');
});
confirmModal.modal('show');
};
/* END Generic Confirm func */
btnType =“btn-primary”
,然后更改OK按钮的代码以包含class =“btn'+ btnType +'”
。这样,您可以传递一个可选参数来更改OK按钮的外观,例如使用btn-danger
进行删除。 - IamNaN我发现这个工具既有用又易于使用,而且看起来很漂亮:http://maxailloud.github.io/confirm-bootstrap/。
要使用它,将.js文件包含在您的页面中,然后运行:
$('your-link-selector').confirmModal();
您可以应用各种选项来使其在进行确认删除操作时看起来更好,我使用:
$('your-link-selector').confirmModal({
confirmTitle: 'Please confirm',
confirmMessage: 'Are you sure you want to delete this?',
confirmStyle: 'danger',
confirmOk: '<i class="icon-trash icon-white"></i> Delete',
confirmCallback: function (target) {
//perform the deletion here, or leave this option
//out to just follow link..
}
});
我可以轻松地使用bootbox.js库处理这种类型的任务。首先,您需要包含bootbox JS文件。然后,在您的事件处理程序函数中,只需编写以下代码:
bootbox.confirm("Are you sure to want to delete , function(result) {
//here result will be true
// delete process code goes here
});

以下解决方案比bootbox.js更好,因为:

dfsq 的回答非常好。我稍微修改了一下以适应我的需求:实际上,我需要一个模态框,以便在单击后,用户还可以导航到相应的页面。异步执行查询并不总是所需的。
使用 Blade
,我创建了文件 resources/views/includes/confirmation_modal.blade.php
:
<div class="modal fade" id="confirmation-modal" tabindex="-1" role="dialog" aria-labelledby="confirmation-modal-label" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4>{{ $headerText }}</h4>
</div>
<div class="modal-body">
{{ $bodyText }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<form action="" method="POST" style="display:inline">
{{ method_field($verb) }}
{{ csrf_field() }}
<input type="submit" class="btn btn-danger btn-ok" value="{{ $confirmButtonText }}" />
</form>
</div>
</div>
</div>
</div>
<script>
$('#confirmation-modal').on('show.bs.modal', function(e) {
href = $(e.relatedTarget).data('href');
// change href of button to corresponding target
$(this).find('form').attr('action', href);
});
</script>
<a data-href="{{ route('data.destroy', ['id' => $data->id]) }}" data-toggle="modal" data-target="#confirmation-modal" class="btn btn-sm btn-danger">Remove</a>
这里没有太多变化,模态框可以像这样包含:
@include('includes.confirmation_modal', ['headerText' => 'Delete Data?', 'bodyText' => 'Do you really want to delete these data? This operation is irreversible.',
'confirmButtonText' => 'Remove Data', 'verb' => 'DELETE'])
仅通过放置动词,它就被使用了。这样,CSRF 也被利用。
对我有帮助,或许对其他人也有帮助。
我希望通过以下方式自己实现-
然后,在弹出窗口中,将有2个确认按钮。
