Select2在嵌入自举模式时不起作用

当我在引导模式中使用select2 (input)时，我不能输入任何东西。就像残疾?在modal之外select2工作正常。

工作示例:http://jsfiddle.net/byJy8/1/ 代码:

<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Panel</h3>
    </div>
    <div class="modal-body" style="max-height: 800px">          
      <form class="form-horizontal">
        <!-- Text input-->
        <div class="control-group">
            <label class="control-label" for="vdn_number">Numer</label>
            <div class="controls">
                <!-- seleect2 -->
                <input name="vdn_number" type="hidden" id="vdn_number"  class="input-large" required=""  />
            </div>
        </div>
      </form>    
    </div>
    <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
    </div>
</div>

$("#vdn_number").select2({
    placeholder: "00000",
    minimumInputLength: 2,
    ajax: {
        url: "getAjaxData/",
        dataType: 'json',
        type: "POST",
        data: function (term, page) {
            return {
                q: term, // search term
                col: 'vdn'
            };
        },
        results: function (data) { // parse the results into the format expected by Select2.
            // since we are using custom formatting functions we do not need to alter remote JSON data
            return {results: data};
        }
    }
});

当前回答

如果你使用jquery移动弹出窗口，你必须重写_handleDocumentFocusIn函数:

.mobile.popup.prototype美元。_handleDocumentFocusIn =函数(e) { If ($(e.c target).close ('.select2-dropdown').length)返回true; ｝

好的，我把它弄好了。

改变

<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Panel</h3>
    </div>
    <div class="modal-body" style="max-height: 800px">

<div id="myModal" class="modal hide fade" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Panel</h3>
    </div>
    <div class="modal-body" style="max-height: 800px">

（从模态中删除 tabindex=“-1”）

我也遇到过类似的问题，我用

    $('#CompId').select2({
              dropdownParent: $('#AssetsModal')
    });

还有modal with select

    <div class="modal fade" id="AssetsModal" role="dialog" 
    aria-labelledby="exampleModalCenterTitle" 
    aria-hidden="true"  style="overflow:hidden;" >
<div class="modal-dialog modal-dialog-centered" role="document">
  <div class="modal-content">
      <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLongTitle" >Добави активи</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
      </div>
      <div class="modal-body">
          <form role="form" action="?action=dma_act_documents_assets_insert&Id=<?=$ID?>" 
                  method="post" name="dma_act_documents_assets_insert" 
                  id="dma_act_documents_assets_insert">
            <div class="form-group col-sm-12">
                  <label for="recipient-name" class="col-form-label">Актив:</label>
                  <span style="color: red">*</span>
                          <select class="form-control js-example-basic-single col-sm-12" 
                                 name="CompId" id="CompId">
                                  <option></option>
                          </select>
              </div>
          </form>
      </div>
  </div>
</div>

但我不知道为什么选择菜单比其他字段小

当开始使用select2时，它是这样开始的。当我取出它时，一切都好了。

有谁能分享一下这方面的经验吗?

谢谢。

对于Select2 v4:

使用dropdownParent将下拉框附加到模态对话框，而不是HTML主体。

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" 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>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <select id="select2insidemodal" multiple="multiple">
          <option value="AL">Alabama</option>
            ...
          <option value="WY">Wyoming</option>
        </select>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>


<script>

$(document).ready(function() {
  $("#select2insidemodal").select2({
    dropdownParent: $("#myModal")
  });
});

</script>

这将附加Select2下拉框，因此它位于模态的DOM中，而不是HTML主体(默认)。看到https://select2.org/dropdown dropdown-placement

在我的情况下，我有两个情态动词同样的问题，所有都解决了使用:

$('.select2').each(function() { 
    $(this).select2({ dropdownParent: $(this).parent()});
})

正如在项目问题#41中，一个用户说。

要使用bootstrap 4.0与服务器端(ajax或json数据内联)，你需要添加所有这些:

$.fn.modal.Constructor.prototype._enforceFocus = function() {};

然后当modal打开时，创建select2:

  // when modal is open
  $('.modal').on('shown.bs.modal', function () {
            $('select').select2({
                  // ....
            });
  });
