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

你可以在$(文档)中再次调用select2 trigger

$(".select2").select2({ 
                width: '120' 
            });

其他回答

我有同样的问题与select2在bootstrap模式，解决方案是删除溢出y: auto;而溢出:隐藏;来自。modal-open和。modal类

下面是使用jQuery删除溢出的示例:

$('.modal').css('overflow-y','visible');
$('.modal').css('overflow','visible');

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>

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.

设置dropdownParent。我必须在modal中设置。modal-content，否则文本会居中。

$("#product_id").select2({
    dropdownParent: $('#myModal .modal-content')
});

基于@pymarco的答案，我写了这个解决方案，它不是完美的，但解决了select2焦点问题，并保持制表符序列在模态内工作

    $.fn.modal.Constructor.prototype.enforceFocus = function () {
        $(document)
        .off('focusin.bs.modal') // guard against infinite focus loop
        .on('focusin.bs.modal', $.proxy(function (e) {
            if (this.$element[0] !== e.target && !this.$element.has(e.target).length && !$(e.target).closest('.select2-dropdown').length) {
                this.$element.trigger('focus')
            }
        }, this))
    }
