我的Twig循环正在生成Bootstrap卡。每张卡中都有一个按钮（＃modal1）打开模式。我的问题是，当我在屏幕上有2张或更多张卡时，由于模式＃1总是会给我第一张卡的ID，所以我无法获得这些卡的社区ID。
是否可以使用JS / Jquery更改id =“ modal1”和data-target =“＃modal1”以使其与每个卡相对应？
谢谢。

更新：在提问者发表评论后...创建/生成新卡片时，请确保
模态是通过
生成的modal1作为div的ID modalToggle作为按钮的ID <div id="modal1">
<button id='modalToggle' >'Add member' </button>
</div> 我们仅在生成卡后立即调用函数afterCreatingNewCard，这将确保将默认ID（“ modal1”和“ moddleToggle”）替换为运行编号
我已针对您的具体情况更新了代码-如果有任何疑问，请告诉我
jquery attr可以帮助完成此任务...在下面进行检查
$(document).ready(function() {
var currentRunningNumber = 1;
yourLogicForCreatingACard(){
//your normal logic will go here
afterCreatingNewCard();
}
afterCreatingNewCard(){
var newRunningNumber = currentRunningNumber + 1;
var newModalName = "modal"+newRunningNumber;
var newModalToggleName = "#modal"+newRunningNumber;
$("#modal1").attr("id", newModalName);
$("#modalToggle").attr("data-target", newModalToggleName);
currentRunningNumber = newRunningNumber;
}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="modal hide fade" id="modal1" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<button id='modalToggle' class="btn btn-primary btn-card" data-toggle="modal" data-target="#modal1">'Add member' </button>
</div>

您可以使用jquery更改ID。但是我不知道如何获取新的id值。你必须这样做。
$('.btn-card').click(function() {
$('.modal').attr('id', newId);
var Id = $('.modal').attr('id');
$('#modal' + Id).modal('toggle');
});

是的，可以动态更改ID。 我今天做了类似的事情。 我在代码中使用了一个动态谷值{{image_item.id}”，它为每个图像创建一个唯一的ID，并为这些图像创建一个唯一的模式弹出窗口。
浏览图像。
'{% for image_item in images %}
<div class="grid-item">
<img src="{{image_item.image_file.url}}" height="500px" width="100%" data-toggle="modal" data-target="#img{{image_item.id}}"/>
</div>
{% endfor %}`
模态代码。
`<!-- Modal starts here -->
{% for image_item in images %}
<div class="modal fade" id="img{{image_item.id}}" tabindex="-1" role="dialog" aria-labelledby="exampleModal3Label" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModal3Label">{{ image_item.image_name }}</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="">
<p> Bunch of codes here </p>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<!-- <button type="button" class="btn btn-primary">Save changes</button> -->
</div>
</div>
</div>
</div>
{% endfor %}`
