Python+Selenium 之页面元素查总结

各种元素定位练习:

1、下拉框(不是select)

因为当前想要选择的下拉框内容,可能需滚动才能显示,进而才能点击,这里利用js,将想要定位到的下拉框元素,滚动到页面可见的范围

tar = self.driver.find_element_by_xpath(path)
self.driver.execute_script("arguments[0].scrollIntoView();", tar)
time.sleep(1)
tar.click()
JS 滚动至页面元素可见

 

2、封装页面元素查询功能,判断元素是否存在,且是可见的

 1     def check_element(self, path, name, tar, time_out=5):
 2         try:
 3             if path == "xpath":
 4                 if tar:
 5                     element1 = WebDriverWait(self.driver, time_out, 1).until(
 6                         lambda x: x.find_element_by_xpath("//*[contains(text(),'" + name + "')]"))
 7                     if not element1.is_displayed():
 8                         return 0
 9                     else:
10                         return element1
11                 else:
12                     element1 = WebDriverWait(self.driver, time_out, 1).until(lambda x: x.find_element_by_xpath(name))
13                     if not element1.is_displayed():
14                         return 0
15                     else:
16                         return element1
17             if path == "css":
18                 if tar:
19                     ele = '[type="text"][placeholder="{name}"]'.format(name=name)
20                     element1 = WebDriverWait(self.driver, time_out, 1).until(
21                         lambda x: x.find_element_by_css_selector(ele))
22                     if not element1.is_displayed():
23                         return 0
24                     else:
25                         return element1
26 
27                 if not tar:
28                     element1 = WebDriverWait(self.driver, time_out, 1).until(
29                         lambda x: x.find_element_by_css_selector(name))
30                     if not element1.is_displayed():
31                         return 0
32                     else:
33                         return element1
34 
35         except Exception as e:
36             # 定位失败时,将图片保存,重命名为调用方法名_时间戳.png
37             self.driver.get_screenshot_as_file(
38                 error_picture_path +'\\' + sys._getframe(1).f_code.co_name + '_' + time.strftime('%Y%m%d%H%M%S', time.localtime(
39                     time.time())) + ".png")
40             return 0
查找元素

 

3、有时在查找元素的时候,又多个属性一致的元素,有时在用find_element_ 查找元素时,返回的元素并不是想要定位的元素,这个时候除了优化定位路径,还有一种方法就是

利用find_elements去查找元素。不过这种方式,对于同一页面,同时展示属性一致的元素而言是不是很适用的,还是要通过优化定位路径去进行精准定位,才能达到你想要的效果

    def check_elements(self, path, element_name, tar=True):
        if path == "xpath":
            if tar:
                element_ = "//*[contains(text(),'" + element_name + "')]"
                Element = self.driver.find_elements_by_xpath(element_)
            else:
                Element = self.driver.find_elements_by_xpath(element_name)
            for el in Element:
                if el.is_displayed():
                    return el
                    break

        if path == "css":
            if tar:
                ele = '[type="text"][placeholder="{name}"]'.format(name=element_name)
                Element = self.driver.find_elements_by_css_selector(ele)
            else:
                Element = self.driver.find_element_by_css_selector(element_name)
            for el in Element:
                if el.is_displayed():
                    return el
                    break
