我有几个超链接,每个超链接都附有一个ID.当我点击此链接时,我想打开一个模态(http://twitter.github.com/bootstrap/javascript.html#modals),并将此ID传递给模态.我搜索谷歌,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>

哪个应该打开:
<div class="modal hide" id="addBookDialog">
<div class="modal-body">
<input type="hidden" name="bookId" id="bookId" value=""/>
</div>
</div>

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

但是,当我单击超链接时,没有任何反应.当我给超链接一个href ="#addBookDialog"时,模态打开就好了,但它不包含任何数据.
我按照这个例子:如何将值参数传递给Bootstrap中的modal.show()函数
(我也试过这个:如何在模态对话框中设置输入值?)

我认为你可以使用jQuery的.on事件处理程序来完成这项工作.
这是你可以测试的小提琴; 只需确保尽可能扩展小提琴中的html框架,以便查看模态.

如果您使用的是Bootstrap 3.2.0,这是一种更简洁的方法.

//populate the textbox
$(e.currentTarget).find('input[name="bookId"]').val(bookId);

如果你在bootstrap 3+上,如果使用Jquery,这可以进一步缩短.

我使用的是 Bootstrap 5,由于不受我控制的限制,我自己无法使用脚本来 show() 模态,因此我依赖于弹出模态的按钮的属性 data-bs-toggle 和 data-bs-target 。
Bootstrap 公开了一些事件(https://getbootstrap.com/docs/5.0/components/modal/),我们可以像这样挂钩代码:
document.getElementById('idModal').addEventListener('show.bs.modal', (e) => {
console.log(e.relatedTarget);
});
Run Code Online (Sandbox Code Playgroud)
在 relatedTarget 中,我们将在数据集中找到指定的数据属性,例如,如果我们有一个如下所示的元素:
<button
class="btn btn-secondary"
data-id="fk_articles"
data-bs-toggle="modal"
data-bs-target="#documentationModal">
Documentation
</button>
Run Code Online (Sandbox Code Playgroud)
然后我们可以通过以下方式到达fk_articles:
console.log( e.relatedTarget.dataset.id )

您的代码将使用正确的模式html结构。
$(function(){
$(".open-AddBookDialog").click(function(){
$('#bookId').val($(this).data('id'));
$("#addBookDialog").modal("show");
});

使用 jquery 这很容易:
如果以下是您的锚链接:
<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>
Run Code Online (Sandbox Code Playgroud)
在模态的显示事件中,您可以访问锚标记,如下所示
//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')
// ...
// ...
})

我发现这种方法很有用:
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:
在 show.bs.modal 中编写逻辑来检查属性是否被解析,例如: id:( e.relatedTarget.hasOwnProperty( 'id' ) ? e.relatedTarget.id : null )
