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};
        }
    }
});

好的，我把它弄好了。

改变

<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">

<div id="myModal" class="modal hide fade" 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">

（从模态中删除 tabindex=“-1”）

在页面上使用此代码

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

    $("#myModal").on('change', '#vdn_number', function () {
        var term = $(this).val();
        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 };
            }
        });
    });
});

我想这对你有帮助

更改select2.css文件

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

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

要使用bootstrap 4.0与服务器端(ajax或json数据内联)，你需要添加所有这些:

$.fn.modal.Constructor.prototype._enforceFocus = function() {};

然后当modal打开时，创建select2:

  // when modal is open
  $('.modal').on('shown.bs.modal', function () {
            $('select').select2({
                  // ....
            });
  });

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>

你可以在$(文档)中再次调用select2 trigger

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