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


当前回答

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...
  });

其他回答

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>

我以前遇到过这个问题,我用yii2解决了它

$.fn.modal.Constructor.prototype.enforceFocus = $.noop;

在这里找到了对我有用的答案:https://github.com/select2/select2-bootstrap-theme/issues/41

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

也不需要删除tabindex。

在我的项目中,我通过重载select2函数来解决这个问题。现在它将检查是否没有dropdownParent,以及函数是否在父元素类型为div.modal的元素上调用。如果是,它将添加该模态作为下拉列表的父类。

这样,就不必在每次创建select2-input框时都指定它。

(function(){
    var oldSelect2 = jQuery.fn.select2;
    jQuery.fn.select2 = function() {
        const modalParent = jQuery(this).parents('div.modal').first();
        if (arguments.length === 0 && modalParent.length > 0) {
            arguments = [{dropdownParent: modalParent}];
        } else if (arguments.length === 1
                    && typeof arguments[0] === 'object'
                    && typeof arguments[0].dropdownParent === 'undefined'
                    && modalParent.length > 0) {
            arguments[0].dropdownParent = modalParent;
        }
        return oldSelect2.apply(this,arguments);
    };
    // Copy all properties of the old function to the new
    for (var key in oldSelect2) {
        jQuery.fn.select2[key] = oldSelect2[key];
    }
})();

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;
