<div class="panel combo-p" style="position: absolute; z-index: 110008; display: block; left: 183.641px; top: 452px; width: 200px;">

<div class="combo-panel panel-body panel-body-noheader" title="" style="width: 200px;">

<div id="_easyui_combobox_i40_0" class="combobox-item">是</div>

<div id="_easyui_combobox_i40_1" class="combobox-item">否</div>

</div>

</div>

sele1= driver.find_element_by_id().click() ----不行

sele2= driver.find_element_by_xpath('div[contains(text(),"否")]').click() ----不行

sele3= driver.find_element_by_xpath('//div[text()="否"]').click() ----不行

sele4= driver.find_element_by_xpath('html/body/div[74]/div/div[1]').click() ----不行

sele5= driver.find_element_by_xpath('//div[contains(@style,"block")]/div[@class="combo-panel panel-body panel-body-noheader"]/div[1]').click

注：前4种时而可以，时而不可以，第5种没有问题
