如何根據按鈕單擊更改 Bootstrap 模式內容

Question

我需要能夠根據單擊的按鈕更改模式內的內容。

例如，如果單擊按鈕 1，它只會顯示class “one”的div ，而其他的將保持隱藏。

 $('#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

你可以看看這個教程： https : //getbootstrap.com/docs/3.4/javascript/#modals-related-target

只需將數據屬性添加到您的按鈕：

<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>

當事件發生時，你可以恢復按鈕的屬性並根據它調整行為：

$('#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

你可以訂閱模式的show.bs.modal事件，檢查的價值relatedTarget事件的屬性，然后顯示/隱藏內部的div基於該目標值

Answer 3

下面舉例。 邏輯：每當您單擊按鈕時，先隱藏所有內容，然后根據您單擊的按鈕顯示特定內容。

參考： 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

你可以這樣做 ：

 $('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'); });
