当我尝试在模态中使用kartik select2插件时,不会出现下拉列表。当我在没有模态的情况下使用它时它就像魅力一样。 这是从插件网站获取的相同代码,但它仍然无法正常工作。我在浏览器生成的源代码中发现select2插件css和js没有从assets文件夹加载
Modal::begin([
'header' => '<h1>Assign Applicant</h1>',
'options' => [
'id' => 'assignApplicantModal',
'tabindex' => false
],
]);
?>
<div class="job-positions-form">
<?php
$form = ActiveForm::begin();
?>
<div class="row">
<div class="col-sm-12">
<div class="col-sm-6">
<?php
$data = ArrayHelper::map(Applicant::find()->where('status = :status', [':status' => 'Active'])->all(), 'id', function($model) {
return $model->first_name . ' ' . $model->last_name;
});
echo $form->field($assign_model, 'applicant_id')->widget(Select2::classname(), [
'data' => $data,
'attribute' => 'applicant_id',
'options' => ['placeholder' => 'Select an applicant'],
'pluginEvents' => [
"select2:selecting" => "function() { "
. "no_position = $('body').data('no_position');"
. "if(no_position>= " . $model->no_of_persons . "){alert('You can select only " . $model->no_of_persons . " applicant(s)');return false;} }",
"select2:select" => "function() { "
. "no_position = $('body').data('no_position');"
. "$('body').data('no_position',++no_position);}",
"select2:unselect" => "function() { "
. "no_position = $('body').data('no_position');"
. "$('body').data('no_position',--no_position);}",
]
]);
?>
</div>
<div class="col-sm-6">
<?php echo $form->field($assign_model, 'applicant_pay')->textInput(['maxlength' => true]); ?>
</div>
<div class="form-group" style="text-align: center;">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
</div>
</div>
<?php ActiveForm::end(); ?>
</div>
<?php
$inlineScript = "$('body').data('no_position'," . count($applicant_id) . ")";
$this->registerJs($inlineScript, \yii\web\View::POS_END, 'my-inline-js');
Modal::end();

当模态的内容是动态的时,不会加载Select2资源,因为最初DOM中没有与Select2相关的代码。
1)您可以通过致电:
预先注册Select2资产\kartik\select2\Select2Asset::register($this);
然后你需要通过调用类似的东西来初始化每个模态内容更改的Select2:
$('#field-id').select2();
2)不是替换模态中的所有HTML,而是提前渲染它,包括空选择(或使用一些初始数据),并且在单击不同的模态触发器后仅更改其内部的数据。 / p>
请参阅此相关的SO问题:
我上次使用的方式:
$dependentDropdown.find('option:not([value=""])').remove();
$dependentDropdown.select2('val', '');
// This can come from AJAX request
var data = [
{'id': 1, 'text': 'Some text 1'},
{'id': 2, 'text': 'Some text 2'}
],
var html = '';
$.each(data, function(key, value) {
html += '<option value="' + value.id + '">' + value.text + '</option>';
});
$dependentDropdown.append(html);

在 yii \ bootstrap \ Modal 中,$('#id_of_the_modal').removeAttr('tabindex');
选项会阻止 Select2 搜索输入工作。
一个简单的修复方法可能是删除tabindex选项。
使用JQuery: HAVING

我的问题是我在呈现我的fancybox模态窗口内容的控制器操作中使用了$this->render()
,而我本应该使用$this->renderAjax()
。现在,它会正确显示选择。
