因功能需求,需要用到联动,特此记录分享
<div class="main-form"> <?php $form = ActiveForm::begin(); ?> <?= $form->field($model, 'cid')->dropDownList( \common\models\service\common\Category::getCateOptions(), [ 'prompt' => '请选择单位', 'onchange'=>' $.post("/carousel/main/cate?id='.'"+$(this).val(),function(data){ $("select#main-aid").html(data); });', ] )->hint('父级,必选') ?> <?= $form->field($model, 'aid')->dropDownList( \common\models\service\common\Category::getCateOptions(), ['prompt' => '请选择子级']) ?> <div class="form-group"> <?= Html::submitButton('Save', ['class' => 'btn btn-success']) ?> </div> <?php ActiveForm::end(); ?> </div>
ublic function actionCate($id) { $departments = Category::find() ->where(['parent_id' => $id]) ->asArray() ->all(); if(!$departments){ echo "<option value='" . 0 . "'>" . "</option>"; } foreach ($departments as $department) { echo "<option value='" . $department['id'] . "'>" . $department['name'] . "</option>"; } }
