我有一个非常基本的简单模式,它是由Bootstrap提供的。我试图得到这项工作,但由于某种原因,它不返回存储在data-id中的值,一切看起来都与bootstrap教程完全相同。我不认为它甚至使用JavaScript。我试着把JavaScript放在另一个文件中,也放在同一个html文件中。
为什么不管用?
Bootstrap版本(根据触发按钮改变模态内容):http://getbootstrap.com/javascript/#modals

将脚本 Package 在文档就绪函数中,如下所示:

$(function(){
    $('#exampleModal').on('show.bs.modal', function (event) {
        var button = $(event.relatedTarget);
        var recipient = button.data('id');
        var modal = $(this);
        modal.find('.modal-title').text('New message to ' + recipient);
        modal.find('.modal-body input').val(recipient);
    });
});

我也在这个问题上挣扎。我直接从Bootstrap页面(www.example.com)复制并粘贴了该示例http://getbootstrap.com/javascript/#modals-related-target,但它不起作用。经过大量的实验,我终于发现JavaScript/jQuery代码:

$('#exampleModal').on('show.bs.modal', function (event) {
 ...
});

必须在加载jQuery库之后放置在源代码中。标准引导模板将

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>


就在代码的末尾,这意味着函数在代码中出现在它之前,它不会运行。一旦我将模态函数移到JavaScript includes之后的.html末尾,它就完美地工作了。

当我试图用Bootstrap 5.2实现可变模态内容示例时,也遇到了同样的问题。我是通过确保

<script>
...
</script>

字符串
在我的弹出模式代码之后出现。
