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
})
如果你是在引导3+，这可以缩短一点，如果使用Jquery。
HTML
<a href="#" data-target="#my_modal" data-toggle="modal" class="identifyingClass" data-id="my_id_value">Open Modal</a>
<div class="modal fade" id="my_modal" tabindex="-1" role="dialog" aria-labelledby="my_modalLabel">
<div class="modal-dialog" role="dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Modal Title</h4>
</div>
<div class="modal-body">
Modal Body
<input type="hidden" name="hiddenValue" id="hiddenValue" value="" />
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">No</button>
<button type="button" class="btn btn-primary">Yes</button>
</div>
</div>
</div>
JQUERY
<script type="text/javascript">
$(function () {
$(".identifyingClass").click(function () {
var my_id_value = $(this).data('id');
$(".modal-body #hiddenValue").val(my_id_value);
})
});
</script>

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。
