html源代码如下
<select id="ca_vdcs" class="pulldown small" name="vdc" style="display: none;">
<option>-- Select a vDC --</option>
<option>Platform-VDC-org</option>
</select>
我想选择'Platform-VDC-org',但下面的代码不起作用.
select = browser.find_element_by_id('ca_vdcs')
select.find_element_by_xpath("//option[@value='Platform-VDC-org']").click()
