【中文标题】自定义 rails 确认框(带有 $.rails.confirm 覆盖)【英文标题】:Custom rails confirm box (with $.rails.confirm override) 【发布时间】:2011-11-18 03:34:49 【问题描述】:我一直在修补这个问题很长时间。
我想用我自己滚动的东西劫持默认的 JS 确认对话框。我想使用完全自定义的布局(引导程序(来自 twitter)对话框面板)。
我所拥有的不起作用。它显示得很好,我可以单击按钮,它会消失。文档说你应该在 Ok 的情况下返回 true,在 Cancel 的情况下返回 false。这很可爱,但它不起作用。看起来我需要一个回调或对最初调用该函数的对象的引用。甚至后者也是不可能的,因为 $.rails.confirm 只传递消息。
(this 问题的第一个答案非常有趣。我需要一种方法使其成为模态,以便等待自定义对话框的返回。)
那么有人可以指点我正确的方向吗?我感觉我要拍东西了。难的!! jQuery UI 只是一个选项,我可以让我的对话框看起来和我现在的完全一样。
这是我所拥有的:
这是放在我的application.erb中
<div id="modal-confirm" class="modal">
<div class="modal-header">
<h3>Are you sure?</h3>
<a href="#" class="close">×</a>
</div>
<div class="modal-body">
<p>VALUE</p>
</div>
<div class="modal-footer">
<a id="modal-accept" href="#" class="btn primary">OK</a>
<a id="modal-cancel" href="#" class="btn secondary">Cancel</a>
</div>
</div>
javascript.js:
function bootStrapConfirmDialog(message)
// get a handle on the modal div (that's already present in the layout).
d = $("#modal-confirm");
// replace the message in the dialog with the current message variable.
$("#modal-confirm div.modal-body p").html(message);
// offset the dialog so it's nice and centered. we like that ;)
// d.offset( top: 400, left: (document.width - d.width) / 2 );
d.center();
// show the dialog.
d.toggle(true);
console.log("popped open");
$(document).ready(function()
// jquery support
$.fn.extend(
center: function ()
return this.each(function()
var top = ($(window).height() - $(this).outerHeight()) / 2;
var left = ($(window).width() - $(this).outerWidth()) / 2;
$(this).css(position:'absolute', margin:0, top: (top > 0 ? top : 0)+'px', left: (left > 0 ? left : 0)+'px');
);
);
// modal stuff
$("#modal-confirm").toggle(false);
// wire up cancel and x button.
$("#modal-confirm #modal-cancel, #modal-confirm a.close").click(function (e)
d.toggle(false);
console.log("clicked cancel");
return false;
);
// wire up OK button.
$("#modal-confirm #modal-accept").click(function (e)
d.toggle(false);
console.log("clicked accept");
return true;
);
// wire up our own custom confirm dialog.
$.rails.confirm = function(message) console.log("start intercept"); return bootStrapConfirmDialog(message); ;
);
最后在我看来:
<%= link_to 'delete customer', customer_path(@customer), :class => 'btn danger', :method => :delete, :confirm => "Are you sure you would like to delete '#@customer.name'?" %>

好吧,我想出了一个办法……但它并不漂亮。我基本上以将实际元素传递给 $.rails.confirm 方法的方式扩展了 jquery-rjs。这样我至少知道如果在模态中按下 OK 按钮会发生什么。所以这是新的时髦代码。
我的新 application.js。奇迹般有效。但是我对我必须覆盖多少东西感到有点不安。我可能弄坏了一些东西,我什至不知道它(rails.formSubmitSelector 和/或 rails.formInputClickSelector)。因此,如果您有更好的解决方案... give :D thx!

【问题讨论】:
【参考方案1】:这是在 Rails 中更改确认框的工作演示:http://rors.org/demos/custom-confirm-in-rails
提供了 Boostrap、jQueryUI 和 Noty 的示例。
【讨论】:
查看链接原文:web.archive.org/web/20121230034912/http://rors.org/demos/…【参考方案2】:我为 Rails 3.1 编写了一个示例,以使用此解决方案更改警报,但不是用引导程序替换本机警报,而是执行以下操作:
将链接/按钮文本更改为“确定?” 2 秒 如果在 2 秒内点击了链接/按钮,则执行该操作 否则链接/按钮会翻转回旧文本并且什么都不会发生。这里有一个要点:https://gist.github.com/2594409

【参考方案3】:有这个功能的拉取请求似乎工作正常 https://github.com/rails/jquery-ujs/pull/196
【讨论】:
【参考方案4】:我发布我的工作解决方案以防它对任何人有帮助。当单击通过以下选择器匹配的链接或按钮时,此解决方案会呈现引导模式:
$('a.ajaxLink, button.ajaxButton')

TypeError: $.blockUI 不是函数 @JosephK 很抱歉听到这个消息。blockUI
和 unblockUI
这些函数在内部使用 jQuery BlockUI 插件。它可在malsup.com/jquery/block 获得。不需要包含该插件,但如果包含它,代码应该开始工作。基本上,这些函数用于显示和隐藏 Ajax 请求进行中指示器。希望有帮助。谢谢。
好的 - 将在未来的项目中尝试。我最终只是手动完成了所有操作:当他们单击自定义框上的“提交”时,我发现了,手动隐藏该框,删除链接的“确认”属性,然后 vanilla-javascript “单击”链接(由于 jQuery 在链接上的点击功能存在一些奇怪的问题)。
$.rails 未定义。以上是关于自定义 rails 确认框(带有 $.rails.confirm 覆盖)的主要内容,如果未能解决你的问题,请参考以下文章
