我想通过以下两种方式之一重置 ReportWidget 的属性：

1) 刷新包含报告小部件的页面时

或者

2) 当某些属性发生变化时

我的 ReportWidget 有 3 个属性：年、季度、月

默认情况下，我显示的是当年的信息。如果用户更改了年份，然后可能指定了该年的季度或月份，则报告会相应地显示。

现在，当他们返回页面时，这些设置将被保存。我想做的是在重新加载或刷新页面时将属性重置为默认值。

此外，如果用户每年都在变化，则其他属性应重置。

我试图用这段代码解决这个问题：

public function defineProperties() {
    return [
        'year' => [
            'title' => 'Year',
            'default' => $this->getDefaultYear(),
            'group' => 'Date',
            'type' => 'dropdown',
            'options' => $this->getYearOptions(),
        ],
        'quarter' => [
            'title' => 'Quarter',
            'type' => 'dropdown',
            'group' => 'Date',
            'options' => $this->getQuarterOptions(),
            'depends' => ['month']
        ],
        'month' => [
            'title' => 'Month',
            'type' => 'dropdown',
            'group' => 'Date',
            'options' => $this->getMonthOptions(),
            'depends' => ['year']
        ]
    ];
}

public function getYearOptions() {

    $query = User::all();

    $years = [];

    foreach($query as $user) {
        $year = date('Y', strtotime($user->created_at));

        $years[$year] = $year;
    }

    $years = array_unique($years);

    return $years;

}

public function getQuarterOptions() {

    $monthCode = Request::input('month'); // Load the year property value from POST

    $yearCode = Request::input('year');

    if ($yearCode && $monthCode) {
        return;
    }

    if ($yearCode) {

        return [
            1 => '1st',
            2 => '2nd',
            3 => '3rd',
            4 => '4th'
        ];
    }
}

public function getMonthOptions() {

    $yearCode = Request::input('year'); // Load the year property value from POST

    if ($yearCode) {
        return;
    }

    $months = [];

    for ($m=1; $m<=12; $m++) {

        $month = date('m', mktime(0,0,0,$m, 1, date('Y')));

        $months[$month] = date('M', mktime(0,0,0,$m, 1, date('Y')));

    }

    return $months;
}

所以这里发生的情况是，如果年份发生变化，它将调用 getMonthOptions() 函数来侦听响应，如果它捕捉到年份，它将不返回任何内容。现在这可行，但显然我的月份列表不包含任何月份。然后我必须关闭属性框并重新打开它以列出月份。

关于如何实现此功能有什么想法吗？谢谢你。

嗯，我已经重写了你的组件，在这里它似乎工作

在init()我们可以根据需要将所有值重置为默认值，之后pageload用户可以根据他的要求进行选择，并使用小部件post requests values来计算东西并根据它工作。但是现在再次refresh page将用户值设置为默认值init()并根据默认值进行计算时no post values，

试试这个，

<?php
namespace October\Demo\ReportWidgets;

use Backend\Classes\ReportWidgetBase;
use RainLab\User\Models\User;
use Request;

class TestWidget extends ReportWidgetBase
{

    public function defineProperties() {
        return [
            'year' => [
                'title' => 'Year',
                'default' => $this->getDefaultYear(),
                'group' => 'Date',
                'type' => 'dropdown',
                'options' => $this->getYearOptions(),
            ],
            'month' => [
