我有一个HTML表的行绑定到数据库行。我希望每行都有一个“删除行”链接,但我想事先与用户确认。
有没有办法使用Twitter引导模式对话框来做到这一点?

多亏了@Jousby的解决方案,我设法让我的工作也很好,但我发现我必须改进他的解决方案的Bootstrap模式标记,使其像官方示例中演示的那样正确呈现。
所以,这是我修改后的泛型确认函数,它工作得很好:
/* 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 */

如果你想用最简单的快捷方式,你可以用这个插件。
但是这个插件是一个使用Bootstrap Modal的替代实现。真正的Bootstrap实现也很容易,所以我不喜欢使用这个插件,因为它会在页面中添加多余的JS内容,这会减慢页面加载时间。
Idea
我喜欢用这种方式来实现它
如果用户单击按钮从列表中删除一个项目,那么JS调用将把项目ID(或任何更重要的数据)放在模态的表单中。 然后在弹出窗口中,会有2个确认按钮。 Yes将提交表单(使用ajax或直接提交表单) 不,会忽略情态动词
代码将像这样(使用Bootstrap)-
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <script> $(document).ready(function() { $("button").click(function() { //Say - $('p').get(0).id - this delete item id $("#delete_item_id").val( $('p').get(0).id ); $('#delete_confirmation_modal').modal('show'); }); }); </script> <p id="1">This is a item to delete.</p> <button type="button" class="btn btn-danger">Delete</button> <!-- Delete Modal content--> <div class="modal fade" id="delete_confirmation_modal" role="dialog" style="display: none;"> <div class="modal-dialog" style="margin-top: 260.5px;"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal">×</button> <h4 class="modal-title">Do you really want to delete this Category?</h4> </div> <form role="form" method="post" action="category_delete" id="delete_data"> <input type="hidden" id="delete_item_id" name="id" value="12"> <div class="modal-footer"> <button type="submit" class="btn btn-danger">Yes</button> <button type="button" class="btn btn-primary" data-dismiss="modal">No</button> </div> </form> </div> </div> </div>
你应该根据你的要求改变表单动作。
快乐编码:)
当涉及到一个相关的大项目时,我们可能需要一些可重复使用的东西。这是我在SO的帮助下得到的东西。

最简单的例子:
bootbox.alert("Hello world!");
来自网站:
该库公开了三种用于模拟原生JavaScript等价物的方法。它们确切的方法签名是灵活的,因为每个方法都可以接受各种参数来定制标签和指定默认值,但它们通常是这样被称为:
bootbox.alert(message, callback)
bootbox.prompt(message, callback)
bootbox.confirm(message, callback)
下面是运行中的代码片段(点击下面的“运行代码片段”):
$(function() { bootbox.alert("Hello world!"); }); <!-- required includes --> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet"/> <!-- bootbox.js at 4.4.0 --> <script src="https://rawgit.com/makeusabrew/bootbox/f3a04a57877cab071738de558581fbc91812dce9/bootbox.js"></script>
得到的配方
对于这个任务,您可以使用已经可用的插件和引导扩展。或者你也可以用3行代码弹出确认窗口。来看看。
假设我们有这样的链接(注意data-href而不是href)或按钮,我们想要对它们进行删除确认:
<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>
这里#confirm-delete指向HTML中的一个模态弹出div。它应该有一个“OK”按钮,配置如下:
<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>
现在你只需要这个小javascript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'));
});
因此,在show.bs.modal event delete button上,href被设置为带有相应记录id的URL。

帖子食谱
我意识到在某些情况下可能需要执行POST或DELETE请求,而不是GET请求。它仍然很简单,没有太多的代码。看看下面使用这种方法的演示:
// 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); }); .modal.loading .modal-content:before { content: 'Loading...'; text-align: center; line-height: 155px; font-size: 20px; background: rgba(0, 0, 0, .8); position: absolute; top: 55px; bottom: 0; left: 0; right: 0; color: #EEE; z-index: 1000; } <script data-require="jquery@*" data-semver="2.0.3" src="//code.jquery.com/jquery-2.0.3.min.js"></script> <script data-require="bootstrap@*" data-semver="3.1.1" src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script> <link data-require="bootstrap-css@3.1.1" data-semver="3.1.1" rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" /> <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"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> <h4 class="modal-title" id="myModalLabel">Confirm Delete</h4> </div> <div class="modal-body"> <p>You are about to delete <b><i class="title"></i></b> record, this procedure is irreversible.</p> <p>Do you want to proceed?</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button> <button type="button" class="btn btn-danger btn-ok">Delete</button> </div> </div> </div> </div> <a href="#" data-record-id="23" data-record-title="The first one" data-toggle="modal" data-target="#confirm-delete"> Delete "The first one", #23 </a> <br /> <button class="btn btn-default" data-record-id="54" data-record-title="Something cool" data-toggle="modal" data-target="#confirm-delete"> Delete "Something cool", #54 </button>

引导2.3
这是我为Bootstrap 2.3模态回答这个问题时所做的代码的原始版本。
$('#modal').on('show', function() {
var id = $(this).data('id'),
removeBtn = $(this).find('.danger');
removeBtn.attr('href', removeBtn.attr('href').replace(/(&|\?)ref=\d*/, '$1ref=' + id));
});
演示:http://jsfiddle.net/MjmVr/1595/
我意识到这是一个非常古老的问题,但自从我今天想知道一个更有效的方法来处理引导情态动词。我做了一些研究,发现了一些比上面显示的解决方案更好的方法,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;
});
});
然后向href询问任何问题/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,确认模式更加通用,因此可以很容易地在网站的其他部分重复使用。
