如何在不提交yii2的情况下将输入值发送给控制器

Question

如何将输入值(数据报警器)发送给控制器，而不是操作。我有一些动作，需要更改日期的值，我必须从datepicker的输入中得到日期的值。我是yii2的新手，我无法意识到这一点。我发现了用ajax发送数据的方法，但是ajax只发送了一个操作(Imho)。提前谢谢。(对不起，我的英语很差)。目前，行动按日期()生效。

这是我行动的例子。

public function actionPara_foiz($fac, $cour, $smena, $lesson_id)
{
    if($cour == "")
    {
        if(Attend::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'lesson_id' => $lesson_id, 'shift_id' => $smena, 'attend' => 0, 'date' => date('Y-m-d')])->count() != 0 && Student::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'shift_id' => $smena])->count() != 0)
        {
            $course1['percent'] = (Attend::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'lesson_id' => $lesson_id, 'shift_id' => $smena, 'attend' => 0, 'date' => date('Y-m-d')])->count() / Student::find()->where(['faculty_id' => $fac, 'course_id' => 1, 'shift_id' => $smena])->count()) * 100;
        }
        else
        {
            echo "";
        }
        if(Attend::find()->where(['faculty_id' => $fac, 'course_id' => 2, 'lesson_id' => $lesson_id, 'shift_id' => $smena, 'attend' => 0, 'date' => date('Y-m-d')])->count() != 0 && Student::find()->where(['faculty_id' => $fac, 'course_id' => 2, 'shift_id' => $smena])->count() != 0)
        {

        }
        else

        $courses = [$course1, $course2, $course3, $course4];

        $childPers = array_column($courses, 'percent');

        if(count($childPers) != 0)
        {
            $parentItem['percent'] = array_sum($childPers)/(count($childPers));

            $sum_para1 = $parentItem['percent'];

Answer 1

我用queryParams解决了这个问题；

$params = Yii::$app->request->queryParams;
$params[date] // this given value when user request date

我不知道，这是不是正确的决定，但我利用了它。

Answer 2

为什么不尝试使用jquery/ajax来获取日期时间选择器，然后通过post或get请求将日期数据传递给控制器。
