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
})

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");
})

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);
});

您可以尝试simpleBootstrapDialog。在这里你可以传递标题，消息，回调选项取消和提交等…

使用此插件包括simpleBootstrapDialog.js文件如下所示

<script type="text/javascript" src="/simpleDialog.js"></script>

基本用法

<script type="text/javascript>
$.simpleDialog();
</script>

自定义标题和描述

$.simpleDialog({
  title:"Alert Dialog",
  message:"Alert Message"
});

与回调

<script type="text/javascript>
$.simpleDialog({
    onSuccess:function(){
        alert("You confirmed");
    },
    onCancel:function(){
        alert("You cancelled");
    }
});
</script>

我发现这个方法很有用:

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:

让你的逻辑在show.bs.modal中检查属性是否被解析，就像这样: id:(e.r relatedtarget。hasOwnProperty('id') ?e.relatedTarget.id: null)

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') 
  })
})
