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?)

Bootstrap 4.0提供了一个修改选项 模态数据使用jquery: https://getbootstrap.com/docs/4.0/components/modal/#varying-modal-content

下面是文档中的script标签:

$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})

它在大多数情况下是有效的。只有对modal的调用不工作。 以下是对脚本的修改,为我工作:

$(document).on('show.bs.modal', '#exampleModal',function(event){
... // same as in above script
})

其他回答

试试这个

$(function(){
 //when click a button
  $("#miButton").click(function(){
    $(".dynamic-field").remove();
    //pass the data in the modal body adding html elements
    $('#myModal .modal-body').html('<input type="hidden" name="name" value="your value" class="dynamic-field">') ;
    //open the modal
    $('#myModal').modal('show') 
  })
})

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');
});

我发现这个方法很有用:

创建点击事件:

$( button ).on('click', function(e) {
    let id = e.node.data.id;

    $('#myModal').modal('show', {id: id});
});

创建show.bs.modal事件:

$('#myModal').on('show.bs.modal', function (e) {

     // access parsed information through relatedTarget
     console.log(e.relatedTarget.id);

});

额外的:

让你的逻辑在show.bs.modal中检查属性是否被解析,就像这样: id:(e.r relatedtarget。hasOwnProperty('id') ?e.relatedTarget.id: null)

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>
