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>

更改select2.css文件

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

to

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

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

$('.modal').on('shown.bs.modal', function (e) {
    $(this).find('.select2me').select2({
        dropdownParent: $(this).find('.modal-content')
    });
})

对于bootstrap3版本,只需在document ready上使用以下代码:

$(document).ready(function(){
    $.fn.modal.Constructor.prototype.enforceFocus = function () {};
});

为了更好地理解tabindex元素是如何工作的,完成公认的回答:

The tabindex global attribute is an integer indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can take several values:   -a negative value means that the element should be focusable, but should not be reachable via sequential keyboard navigation;   -0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the platform convention;   -a positive value means should be focusable and reachable via sequential keyboard navigation; its relative order is defined by the value of the attribute: the sequential follow the increasing number of the tabindex. If several elements share the same tabindex, their relative order follows their relative position in the document.
