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?)


当前回答

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') 
  })
})

其他回答

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">&times;</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>

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') 
  })
})

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
})

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


如果你使用Bootstrap 3.2.0,这里有一个更干净的方法。

链接的HTML

<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>

JavaScript资本

//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);
});
