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

根据官方的select2文档，这个问题的发生是因为Bootstrap模态倾向于从模态之外的其他元素窃取焦点。

默认情况下，Select2将下拉菜单附加到元素上，它被认为是“在模式之外”。

相反，使用dropdownParent设置将下拉菜单附加到模式本身:

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

其他回答

$("#IlceId").select2({
    allowClear: true,
    multiple: false,
    dropdownParent: $("#IlceId").parent(),
    escapeMarkup: function (m) {
        return m;
    },
});

这段代码正在工作。谢谢你！

.select2-close-mask{
    z-index: 2099;
}
.select2-dropdown{
    z-index: 3051;
}

这是我使用select2 4.0.0的解决方案。只需要覆盖select2.css导入下面的css。请确保z指数大于对话框或模态。我只是在默认值上加了2000。因为我的对话框的z-index是1000。

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

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.

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>
