selenium Select用法笔记

• select_by value:参数为option中的value属性，例如：HTML代码中 <ignore_js_op> ，应该是value="volvo"这个值，所以应该为小写;
• select_by_visible_text:参数为option的text值， <ignore_js_op> ，应该是红线标出部分的值，所以应该是大写;
• Select(driver.find_element_by_name("isImportant")).select_by_visible_text(u"是")

• deselect_all(self)

| Clear all selected entries. This is only valid when the SELECT supports multiple selections.
| throws NotImplementedError If the SELECT does not support multiple selections

• select_by_index(self, index)

| Select the option at the given index. This is done by examing the "index" attribute of an
| element, and not merely by counting.

•  select_by_value(self, value)
