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?)

例如,对于更新href值,我会做如下操作:

<a href="#myModal" data-toggle="modal" data-url="http://example.com">Show modal</a>

$('#myModal').on('show.bs.modal', function (e) {
    var url = $(e.relatedTarget).data('url');
    $(e.currentTarget).find('.any-class').attr("href", "url");
})

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>

我认为你不需要jQuery。你可以使用onclick事件并将bookId传递给javascript函数,在那里你可以查询元素并设置输入值。

<a data-toggle="modal" data-id="@book. "Id" onclick="passBookId('@book.Id')" title="添加此条目" class="open-AddBookDialog"></a> .

and

<script>
    function passBookId(bookId) {
        let inputElement= document.document.querySelector("div.modal-dialog input[name='bookId'");
        if (inputElement) {
            inputElement.value = bookId;
        }
        return true;
    }
</script>

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') 
  })
})

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')
    // ...
    // ...
})
