我有两个超链接,每个都有一个ID附加。当我点击这个链接时,我想打开一个模态(http://twitter.github.com/bootstrap/javascript.html#modals),并将这个ID传递给模态。我在谷歌上搜索,但我找不到任何可以帮助我的东西。

这是代码:

<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>

应该打开:

<div class="modal hide" id="addBookDialog">
    <div class="modal-body">
        <input type="hidden" name="bookId" id="bookId" value=""/>
    </div>
</div>

下面这段代码:

$(document).ready(function () {
    $(".open-AddBookDialog").click(function () {
        $('#bookId').val($(this).data('id'));
        $('#addBookDialog').modal('show');
    });
});

然而,当我点击超链接时,什么都没有发生。当我给超链接<a href="#addBookDialog"…>,模态打开得很好,但它不包含任何数据。

我遵循了这个例子:如何在Bootstrap中将值参数传递给modal.show()函数

(我也试过这个:如何在模态对话中设置输入值?)

您的代码将与正确的modal html结构一起工作。

$(function(){ $(".open-AddBookDialog").click(function(){ $('#bookId').val($(this).data('id')); $("#addBookDialog").modal("show"); }); }); <html> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> <a data-id="@book.Id" title="Add this item" class="open-AddBookDialog">Open Modal</a> <div id="addBookDialog" class="modal fade" tabindex="-1" role="dialog"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-body"> <input type="hidden" name="bookId" id="bookId" value=""/> </div> </div><!-- /.modal-content --> </div><!-- /.modal-dialog --> </div><!-- /.modal --> </html>

引导4.3 -使用下面代码片段中的代码-更多信息请点击这里

$('#exampleModal').on('show.bs.modal', function (event) { let bookId = $(event.relatedTarget).data('bookid') $(this).find('.modal-body input').val(bookId) }) a.btn.btn-primary.open-AddBookDialog {color: white } <!-- Initialize Bootstrap 4 --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script> <!-- BUTTON --> <a class="btn btn-primary open-AddBookDialog" data-toggle="modal" data-target="#exampleModal" data-bookid="@book.Id" title="Add this item" >Open</a> <!-- MODAL --> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-body"> <input type="hidden" name="bookId" id="bookId" value=""/> <input type="text" class="form-control" id="recipient-name"> </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> </div> </div> </div> </div>

我发现这对我有用:

在链接中:

<button type="button" class="btn btn-success" data-toggle="modal" data-target="#message<?php echo $row['id'];?>">Message</button>

在情态动词中:

<div id="message<?php echo $row['id'];?>" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <?php echo $row['id'];?>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

我认为您可以使用jQuery的.on事件处理程序来实现这一点。

这是一个你可以测试的小提琴;只要确保在小提琴中尽可能地展开HTML框架,这样你就可以查看模式。

HTML

<p>Link 1</p>
<a data-toggle="modal" data-id="ISBN564541" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a>

<p>&nbsp;</p>


<p>Link 2</p>
<a data-toggle="modal" data-id="ISBN-001122" title="Add this item" class="open-AddBookDialog btn btn-primary" href="#addBookDialog">test</a>
    
<div class="modal hide" id="addBookDialog">
 <div class="modal-header">
    <button class="close" data-dismiss="modal">×</button>
    <h3>Modal header</h3>
  </div>
    <div class="modal-body">
        <p>some content</p>
        <input type="text" name="bookId" id="bookId" value=""/>
    </div>
</div>

JAVASCRIPT

$(document).on("click", ".open-AddBookDialog", function () {
     var myBookId = $(this).data('id');
     $(".modal-body #bookId").val( myBookId );
     // As pointed out in comments, 
     // it is unnecessary to have to manually call the modal.
     // $('#addBookDialog').modal('show');
});

这是如此简单的jquery:

如果下面是你的锚链接:

<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>

在你的模态的显示事件中,你可以像下面这样访问锚标记

//triggered when modal is shown
$('#modal_id').on('shown.bs.modal', function(event) {

    // The reference tag is your anchor tag here
    var reference_tag = $(event.relatedTarget); 
    var id = reference_tag.data('id')
    // ...
    // ...
})


我是bootstrap 5,由于我控制之外的约束,我不能显示()脚本的模态,所以我依赖于弹出模态的按钮的属性data-b -toggle和data-b -target。

Bootstrap暴露了一些事件(https://getbootstrap.com/docs/5.0/components/modal/),我们可以像这样钩住代码:

document.getElementById('idModal').addEventListener('show.bs.modal', (e) => {
    console.log(e.relatedTarget);
});

在relatedTarget中,我们将在dataset中找到指定的数据属性,例如,如果我们有一个看起来像这样的元素:

<button
    class="btn btn-secondary"
    data-id="fk_articles"
    data-bs-toggle="modal"
    data-bs-target="#documentationModal">
        Documentation
</button>

然后我们可以通过以下方式到达fk_articles:

console.log( e.relatedTarget.dataset.id )
