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

从模式中删除tabindex="-1"。我检查了这个解决方案，它是有效的。

其他回答

只需删除tabindex="-1"并添加样式overflow:hidden

这里有一个例子:

<div id="myModal" class="modal fade" role="dialog" style="overflow:hidden;">
    <!---content modal here -->
</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
}

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

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

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.

在我的情况下，我这样做，它工作。我使用bundle来加载它，在这种情况下，它为我工作

 $(document).on('select2:select', '#Id_Producto', function (evt) {
   // Here your code...
  });
