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>

JS

$("#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};
        }
    }
});

这里是“正确的方法”:Select2在嵌入引导模式时不起作用

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>

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

我也有同样的问题,更新.select2-container的z-index应该可以解决这个问题。确保模态的z指数低于select2的z指数。

.select2-container {
    z-index: 99999;
}

更新: 如果上面的代码不能正常工作,也可以像@breq建议的那样从你的模式中删除表索引

在Bootstrap模态中使用Select2 Bootstrap 5主题,如下所示:

修复了select2 & bootstrap模态搜索输入错误。 修复选择选项后的select2 & bootstrap模式滚动错误。

jQuery(function() { $('.my-select2').each(function() { $(this).select2({ theme: "bootstrap-5", dropdownParent: $(this).parent(), // fix select2 search input focus bug }) }) // fix select2 bootstrap modal scroll bug $(document).on('select2:close', '.my-select2', function(e) { var evt = "scroll.select2" $(e.target).parents().off(evt) $(window).off(evt) }) }) <!DOCTYPE html> <html> <head> <!-- Styles --> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" /> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css" /> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/select2-bootstrap-5-theme@1.2.0/dist/select2-bootstrap-5-theme.min.css" /> <!-- Scripts --> <script src="https://cdn.jsdelivr.net/npm/jquery@3.5.0/dist/jquery.slim.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/js/select2.min.js"></script> </head> <body> <!-- Button trigger modal --> <button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal"> Launch demo modal </button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button> </div> <div class="modal-body"> Select2 v4.1 <select class="my-select2"> <option>Test 1</option> <option>Test 2</option> <option>Test 3</option> <option>Test 4</option> <option>Test 5</option> <option>Test 6</option> <option>Test 7</option> <option>Test 8</option> <option>Test 9</option> <option>Test 10</option> </select> </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> </body> </html>

好吧,我知道我迟到了。但让我和你们分享对我有效的方法。 tabindex和z-index解决方案不适合我。

设置select元素的父元素按照select2站点上列出的常见问题工作。
