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
在Bootstrap模态中使用Select2 Bootstrap 5主题，如下所示:
修复了select2 & bootstrap模态搜索输入错误。
修复选择选项后的select2 & bootstrap模式滚动错误。
jQuery(function() {
$('.my-select2').each(function() {
$(this).select2({
theme: "bootstrap-5",
dropdownParent: $(this).parent(), // fix select2 search input focus bug
})
})
// fix select2 bootstrap modal scroll bug
$(document).on('select2:close', '.my-select2', function(e) {
var evt = "scroll.select2"
$(e.target).parents().off(evt)
$(window).off(evt)
})
})

我在github上找到了select2的解决方案
https://github.com/ivaynberg/select2/issues/1436
对于bootstrap 3，解决方案是:
$.fn.modal.Constructor.prototype.enforceFocus = function() {};
Bootstrap 4重命名了enforceFocus方法为_enforceFocus，所以你需要修补它:
$.fn.modal.Constructor.prototype._enforceFocus = function() {};
从以上链接复制的解释:
Bootstrap向focusin事件注册了一个监听器，它检查被聚焦的元素是覆盖本身还是它的后代——如果不是，它只是重新聚焦在覆盖上。随着select2下拉框被附加到正文，这有效地防止你在文本框中输入任何东西。
您可以通过覆盖在模态上注册事件的enforceFocus函数来快速修复这个问题
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
