Yii2：contentOptions(GridView)中的动态样式

在Yii2中有更优雅的动态样式方法：

<?= GridView::widget([
    'dataProvider' => $dataProvider,'filterModel' => $searchModel,'columns' => [
        ['class' => 'yii\grid\SerialColumn'],[
           'attribute' => 'fecha','contentOptions' => ['style' => 'color: '.$dataProvider->models[0]->fechaVerif->color],],['class' => 'yii\grid\ActionColumn'],]); ?>

一边使用匿名功能？我尝试过类似的东西：

'contentOptions' => ['style' => 'color: '. fechaVerif.color]

但它显然没有用.

解决方法

查看Yii2中的Column :: renderDataCell实现：

public function renderDataCell($model,$key,$index)
{
    if ($this->contentOptions instanceof Closure) {
        $options = call_user_func($this->contentOptions,$model,$index,$this);
    } else {
        $options = $this->contentOptions;
    }
    return Html::tag('td',$this->renderDataCellContent($model,$index),$options);
}

因此,做你想做的事的唯一方法是：

[
                'attribute' => 'fecha','contentOptions' => function($model)
                    {
                        return ['style' => 'color:' . $model->fechaVerif->color];
                    }
            ],
