通过在 Yii2 中使用 kartik select2 插件,我尝试为国家和州创建依赖关系下拉列表。
国家和州的表单字段:
$url = yii\helpers\Url::toRoute('op-client/lists');
$this->registerJs($this->render('script.js'), \yii\web\VIEW::POS_READY);
$form->field($model, 'country_id')->widget(Select2::classname(), [
'data' => $countryData,
'language' => 'en',
'options' => ['placeholder' => 'Select'],
'pluginOptions' => [
'allowClear' => true,
],
'pluginEvents' =>
[
'change' => 'function()
{
getstate
(
$("#select2-opclient-country_id-container").val(),
"'.$url.'"
)
}',
],
]).'
$form->field($model, 'states_id')->widget(Select2::classname(), [
'data' => $statesData,
'language' => 'en',
'options' => ['placeholder' => 'Select'],
'pluginOptions' => [
'allowClear' => true,
],
]).'
脚本.js
function getstate($countryid,url)
{
//console.log(startdate + enddate);
var csrfToken = $('meta[name="csrf-token"]').attr("content");
$.ajax({
type:"POST",
cache:false,
url:url,
data:{countryid:countryid, _crsf:csrfToken},
success:function(data){
$("#select2-opclient-states_id-container").val(data);
},
})
}
Controller :
public function actionLists()
{
$request = Yii::$app->request;
$country = $request->post('countryid');
$countStates = OpStates::find()
->where(['country_id' => $country])
->count();
$states = OpStates::find()
->where(['country_id' =>$country])
->all();
if($countStates > 0)
{
foreach($states as $state){
echo "<option value='".$state->id."'>".$state->state_name."</option>";
}
}
else
{
echo "<option></option>";
}
}
当我运行该程序时,它显示错误“Uncaught ReferenceError:未定义countryid”。 但我想我已经将 Countryid 传递给了它?我哪里做错了?
任何帮助/建议将不胜感激。谢谢
最佳答案
请检查下面的代码,我认为您在country_id变量名称中犯了一些小错误。
public function actionLists()
{
$request = Yii::$app->request;
$country = $request->post('country_id');
$countStates = OpStates::find()
->where(['country_id' => $country])
->count();
$states = OpStates::find()
->where(['country_id' =>$country])
->all();
if($countStates > 0)
{
foreach($states as $state){
echo "<option value='".$state->id."'>".$state->state_name."</option>";
}
}
else
{
echo "<option></option>";
}
}
这里
function getstate(countryid,url)
{
//console.log(startdate + enddate);
var csrfToken = $('meta[name="csrf-token"]').attr("content");
$.ajax({
type:"POST",
cache:false,
url:url,
data:{countryid:countryid, _crsf:csrfToken},
success:function(data){
$("#select2-opclient-states_id-container").val(data);
},
})
}
它将解决您的问题。
