如何根据按钮单击更改 Bootstrap 模式内容

Question

我需要能够根据单击的按钮更改模式内的内容。

例如，如果单击按钮 1，它只会显示class “one”的div ，而其他的将保持隐藏。

 $('#exampleModalCenter').modal('toggle')

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <button type="button" class="btn" data-toggle="modal" data-target="#exampleModalCenter">one</button> <button type="button" class="btn" data-toggle="modal" data-target="#exampleModalCenter">two</button> <!-- Latest compiled and minified CSS --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> <!-- jQuery library --> <!-- Latest compiled JavaScript --> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script> <button type="button" class="btn" data-toggle="modal" data-target="#exampleModalCenter">three</button> <!-- Modal --> <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true"> <div class="modal-dialog modal-dialog-centered" role="document"> <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> </div> <div class="modal-body"> <div class="one">Button one content</div> <div class="two">Button two content</div> <div class="one">Button three content</div> </div> </div> </div> </div>

Answer 1

你可以看看这个教程： https : //getbootstrap.com/docs/3.4/javascript/#modals-related-target

只需将数据属性添加到您的按钮：

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="one">Open modal for One</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="two">Open modal for Two</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="three">Open modal for Three</button>

当事件发生时，你可以恢复按钮的属性并根据它调整行为：

$('#yourModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget); // Button that triggered the modal
  var recipient = button.data('name'); // Extract info from data-* attributes

  // Here, you can change the behavior according to the button clicked :
  switch(recipient) {
    case 'one':
      $('.one').show();
      break;
    case 'two':
      $('.two').show();
       break;
    // etc...
  }
});

Answer 2

你可以订阅模式的show.bs.modal事件，检查的价值relatedTarget事件的属性，然后显示/隐藏内部的div基于该目标值

Answer 3

下面举例。 逻辑：每当您单击按钮时，先隐藏所有内容，然后根据您单击的按钮显示特定内容。

参考： https : //getbootstrap.com/docs/3.3/javascript/#modals-related-target

 $(".btn").click(function () { $(".parent").children().each(function () { $(this).hide(); }); $(`div.${$(this).attr("id")}`).show(); });

Answer 4

 $(document).on("click",".modal-open",function(){ var button_val = $(this).attr("data-val"); $('#exampleModalCenter').modal('show'); $(".conditional-div").hide(); $("#exampleModalCenter ."+button_val).show(); })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <button type="button" class="btn modal-open" data-val="one" >one</button> <button type="button" class="btn modal-open" data-val="two" >two</button> <button type="button" class="btn modal-open" data-val="three" >three</button> <!-- Latest compiled and minified CSS --> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> <!-- jQuery library --> <!-- Latest compiled JavaScript --> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script> <!-- Modal --> <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true"> <div class="modal-dialog modal-dialog-centered" role="document"> <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> </div> <div class="modal-body"> <div class="one conditional-div">Button one content</div> <div class="two conditional-div">Button two content</div> <div class="three conditional-div">Button three content</div> </div> </div> </div> </div>

Answer 5

你可以这样做 ：

 $('button.btn-open-modal').on('click', function(){ let targetClass = $(this).attr("target-class"); $("#exampleModalCenter div.modal-body > div").each(function(){ if($(this).hasClass(targetClass)){ $(this).show(); }else { $(this).hide(); } }); $('#exampleModalCenter').modal('toggle'); });
