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};
        }
    }
});

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

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; ｝

更改select2.css文件

z-index: 9998;
...
z-index: 9999;
...
z-index: 10000;

z-index: 10000;
...
z-index: 10001;
...
z-index: 10002;

这对所有人都有效

body .select2-container {
    z-index: 9999 !important;
}

我只是通过包含select2。min。css来让它工作

试一试

我的模态html bootstrap 3是

<div id="changeTransportUserRequestPopup" class="modal fade" role="dialog">
    <div class="modal-dialog" style="width: 40%!important; ">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h3>Warning</h3>
            </div>
            <div class="modal-body" id="changeTransportUserRequestPopupBody">
                <select id="cbTransport" class="js-example-basic-single" name="cbTransport" style="width:100%!important;"></select>
            </div>
            <div class="modal-footer">
                <button id="noPost" class="btn btn-default" name="postConfirm" value="false" data-dismiss="modal">Cancel</button>
                <button type="submit" id="yesChangeTransportPost" class="btn btn-success" name="yesChangeTransportPost" value="true" data-dismiss="modal">Yes</button>
            </div>
        </div>
    </div>
</div>

如果你的iPad键盘在点击select2输入时隐藏了引导模式，你可以通过在select2输入初始化后添加以下规则来解决这个问题:

if (navigator.userAgent.match(/iPhone|iPad|iPod/i)) {
   var styleEl = document.createElement('style'), styleSheet;
   document.head.appendChild(styleEl);
   styleSheet = styleEl.sheet;
   styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);
   document.body.scrollTop = 0; // Only for Safari
}

摘自https://github.com/angular-ui/bootstrap/issues/1812#issuecomment-135119475

编辑:如果你的选项没有正确显示，你需要在初始化select2时使用dropdownParent属性:

$(".select2").select2({
    dropdownParent: $("#YOURMODALID")
});

祝你好运
