fastadmin 跳转后限定搜索条件

记录：从一个页面跳转进入此列表页并传入参数进行限定搜索条件。
php代码示例：

	public function _initialize()
    {
        parent::_initialize();
        $this->model = new \app\admin\model\user\LoanBill;
        $this->view->assign("statusList", $this->model->getStatusList());
        // 接收传来的参数
        $user_loan_id = input('ids/d',0);
        $this->assignconfig('user_loan_id',$user_loan_id);
        $this->view->assign("user_loan_id", $user_loan_id);
    }
    /**
     * 查看
     */
    public function index()
    {
        //当前是否为关联查询
        $this->relationSearch = true;
        //设置过滤方法
        $this->request->filter(['strip_tags', 'trim']);
        if ($this->request->isAjax()) {
            //如果发送的来源是Selectpage，则转发到Selectpage
            if ($this->request->request('keyField')) {
                return $this->selectpage();
            }
            list($where, $sort, $order, $offset, $limit) = $this->buildparams();
            
            // 接收传来的参数进行限定条件
            $params = [];
            if(input('user_loan_id')){
                $params = ['user_loan_id'=>input('user_loan_id')];
            }
            
            $list = $this->model
                    ->with(['user','loan'])
                    ->where($where)
                    ->where($params)
                    ->order($sort, $order)
                    ->paginate($limit);

            
            foreach ($list as $row) {
                $row->visible(['id','repayment_date','money','interest','violate','status','repayment_time','createtime','updatetime']);
                $row->visible(['user']);
				$row->getRelation('user')->visible(['nickname','mobile','invite_code','avatar']);
				$row->visible(['loan']);
				$row->getRelation('loan')->visible(['money','service','status']);
            }

            $result = array("total" => $list->total(), "rows" => $list->items());

            return json($result);
        }
        return $this->view->fetch();
    }

js部分代码：

define(['jquery', 'bootstrap', 'backend', 'table', 'form'], function ($, undefined, Backend, Table, Form) {
    var user_loan_id = Config.user_loan_id;
    var Controller = {
        index: function () {
            // 初始化表格参数配置
            Table.api.init({
                extend: {
                    index_url: 'user/loan_bill/index/user_loan_id/'+user_loan_id + location.search,
                    add_url: 'user/loan_bill/add/ids/'+ user_loan_id,
                    edit_url: 'user/loan_bill/edit/ids/'+ user_loan_id,

                    table: 'user_loan_bill',
                }
            });
            
            ......

        add: function () {
