限制日期不得超过60天

Question

我正在使用Drupal 8自定义表单。我想限制或阻止用户购买日期不超过60天 我尝试了三种方法。它不会工作。请帮帮我 我尝试使用jquery，但样式受影响，格式也已更改。

$form['product_info']['install_date'] = [
      '#type' => 'date',
      '#title' => $this->t('Date of Install *'),
      '#default_value' => $this->store->get('install_date') ? $this->store->get(
            'install_date') : "",
      '#date_format' => "m/d/Y",
      '#size' => 10,
//First method
     '#minDate'=> '-60',
 //second Method
     '#datepicker_options' => array('minDate' => 0,),
//Third Method    
'     #attributes' => ('min' =>  \Drupal::service('date.formatter')->format(REQUEST_TIME, '-60', 'Y-m-d'),
    ),
            // '#required' => TRUE,.
      '#prefix' => '<div class="field-wrapper">',
      '#suffix' => '</div>',
      '#error_no_message' => TRUE,
    ];
