Question

我正在尝试使用简单的模态/弹出式指南，以便有一个很好的删除确认对话框，但我似乎永远无法让它们中的任何一个工作。

我目前正在处理的那个只是淡出屏幕但没有对话框出现。这个来自：http://www.tutorialrepublic.com/twitter-bootstrap-tutorial/bootstrap-modals.php

<!-- Button HTML (to Trigger Modal) -->
<a href="#myModal" role="button" class="btn btn-large btn-primary" data-toggle="modal">Launch Demo Modal</a>

<!-- Modal HTML -->
<div id="myModal" class="modal hide fade">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h3>Confirmation</h3>
    </div>
    <div class="modal-body">
        <p>Do you want to save changes you made to document before closing?</p>
        <p class="text-warning"><small>If you don't save, your changes will be lost.</small></p>
    </div>
    <div class="modal-footer">
        <a href="#" class="btn">Close</a>
        <a href="#" class="btn btn-primary">Save changes</a>
    </div>
</div>

我当前的deleteFunction是这样的：

按钮

<span class="item-delete-button">
      <button type="button" onclick="deleteFunction(this)" class="btn btn-danger col-lg-3 col-lg-offset-3"><span style="margin-right: 5px" class="glyphicon glyphicon-trash"></span>Delete</button>
</span>

JQuery的

function deleteFunction(element) {
        var newID = $(element).closest("td").find("span.ID").text();

        $(element).closest("table").removeClass("table-hover");
        $(element).closest("tr").css('background-color', 'red');     

        $(document).ready(function () {
            var answer = confirm("Are you sure you want to delete this movie?");
            if (answer) {
                $.post(
            '@Url.Action("customDelete", "Movie")',
            {
                'id': newID
            },
            function (data) { },
            "json"
            );
                $(element).closest("tr").remove();
                return true;
            } else {
                $(element).closest("tr").css('background-color', 'initial');
                return false;
            }
        });
    }

我想要的只是一个简单的删除确认。

我现在已经查看了20多个指南，但仍然无法正确实现任何内容。（也在Chrome中运行Debug）

这是我的整个视图，也许是冲突的......？（对所有这些都是新的）

感谢您的帮助！

不确定为什么这么难，但最终我还是开始工作了。

按钮

 <span class="item-delete-button"> <button class="btn btn-danger col-lg-3 col-lg-offset-3" data-toggle="modal" data-target="#@item.ID" onclick="deleteStart(this)"> Delete </button> </span>

<强>模态

<div class="modal fade" id="@item.ID" 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">Delete</h4> </div> <div class="modal-body"> <span style="font-size: 20px">Are you sure you want to delete Employee: @Html.DisplayFor(modelItem => item.YOUR_ITEM)?</span> </div> <div class="modal-footer"> <button type="button" onclick="deleteStopped(this)" class="btn btn-default" data-dismiss="modal">Cancel</button> <button type="button" onclick="deleteFunction(this)" class="btn btn-danger">Confirm Delete</button> </div> </div> </div> </div>

注意：#@item.ID是我的@model我的视图ID，因为我的视图在我的数据库中构建了List个项目。
