| 方法/属性 | 方法/属性描述 |
|---|---|
| select_by_value() | 根据值选择 |
| select_by_index() | 根据索引选择 |
| select_by_visible_text | 根据文本选择 |
| deselect_by_value | 根据值反选 |
| deselect_by_index | 根据索引反选 |
| deselect_by_visible_text | 根据文本反选 |
| deselect_all | 反选所有 |
| all_selected_options | 所有选中选项 |
| first_selected_option | 第一个选择选项 |
