本文翻譯自：Passing data to a bootstrap modal
I've got a couple of hyperlinks that each have an ID attached. 我有幾個超鏈接，每個超鏈接都附有一個ID。 When I click on this link, I want to open a modal ( http://twitter.github.com/bootstrap/javascript.html#modals ), and pass this ID to the modal. 當我點擊此鏈接時，我想打開一個模態（ http://twitter.github.com/bootstrap/javascript.html#modals ），並將此ID傳遞給模態。 I searched on google, but I couldn't find anything that could help me. 我搜索谷歌，但我找不到任何可以幫助我的東西。
This is the code: 這是代碼：
<a data-toggle="modal" data-id="@book.Id" title="Add this item" class="open-AddBookDialog"></a>
Which should open: 哪個應該打開：
<div class="modal hide" id="addBookDialog">
<div class="modal-body">
<input type="hidden" name="bookId" id="bookId" value=""/>
</div>
</div>
With this piece of code: 有了這段代碼：
$(document).ready(function () {
$(".open-AddBookDialog").click(function () {
$('#bookId').val($(this).data('id'));
$('#addBookDialog').modal('show');
});
});
However, when I click the hyperlink, nothing happens. 但是，當我單擊超鏈接時，沒有任何反應。 When I give the hyperlink <a href="#addBookDialog" ...> , the modal opens just fine, but it does't contain any data. 當我給超鏈接<a href="#addBookDialog" ...> ，模態打開就好了，但它不包含任何數據。
I followed this example: How to pass values arguments to modal.show() function in Bootstrap 我按照這個例子： 如何將值參數傳遞給Bootstrap中的modal.show（）函數
(and I also tried this: How to set the input value in a modal dialogue? ) （我也試過這個： 如何在模態對話框中設置輸入值？ ）

I think you can make this work using jQuery's .on event handler. 我認爲你可以使用jQuery的.on事件處理程序來完成這項工作。
Here's a fiddle you can test; 這是你可以測試的小提琴; just make sure to expand the HTML frame in the fiddle as much as possible so you can view the modal. 只需確保儘可能擴展小提琴中的HTML框架，以便查看模態。

// As pointed out in comments,
// it is unnecessary to have to manually call the modal.

Here's how I implemented it working from @mg1075's code. 以下是我使用@ mg1075代碼實現它的方法。 I wanted a bit more generic code so as not to have to assign classes to the modal trigger links/buttons: 我想要一些更通用的代碼，以便不必爲模態觸發鏈接/按鈕分配類：

}
$('#my_element_id').val(data_id);

Here is a cleaner way to do it if you are using Bootstrap 3.2.0 . 如果您使用的是Bootstrap 3.2.0，這是一種更簡潔的方法 。
Link HTML 鏈接HTML
<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>
Modal JavaScript 模態JavaScript
//triggered when modal is about to be shown
$('#my_modal').on('show.bs.modal', function(e) {
//get data-id attribute of the clicked element
var bookId = $(e.relatedTarget).data('book-id');
//populate the textbox
$(e.currentTarget).find('input[name="bookId"]').val(bookId);
});

If you are on bootstrap 3+, this can be shortened a bit further if using Jquery. 如果你在bootstrap 3+上，如果使用Jquery，這可以進一步縮短。

Your code would have worked with correct modal html structure. 您的代碼可以使用正確的模態html結構。
$(function(){ $(".open-AddBookDialog").click(function(){ $('#bookId').val($(this).data('id')); $("#addBookDialog").modal("show"); }); });
