我正在尝试从此页面获取插件。如果该项目是可定制的。
收集完所有内容后divs，我尝试转到页面顶部（不起作用）。我检查是否存在可定制 div的。如果是这样，将其滚动到视图中，单击“添加”按钮并获取“添加详细信息”。我试过了，actionChains没用。execute_script也什么也没做。单击之前有效，但是在页面上上下滚动有点把它弄乱了。一直在努力解决这个问题。任何帮助是极大的赞赏。
for i in range(6):
item_dvs = driver.find_elements_by_class_name('_2wg_t')
driver.execute_script("window.scrollBy(0, 3100)")
driver.execute_script("window.scrollBy(0,-18500);")
for div in item_dvs:
try:
name = div.find_element_by_class_name('styles_itemNameText__3bcKX')
price = div.find_element_by_class_name('rupee')
if div.find_elements_by_class_name('styles_itemDesc__MTsVd'):
desc = div.find_element_by_class_name('styles_itemDesc__MTsVd').text
else:
desc = None
is_cust = div.find_element_by_class_name('_1C1Fl _23qjy')
if is_cust:
driver.execute_script("arguments[0].scrollIntoView();", is_cust)
首先，我建议您使用，WebDriverWait因为这些行if div.find_elements_by_class_name('styles_itemDesc__MTsVd')和is_cust = div.find_element_by_class_name('_1C1Fl _23qjy')当元素不存在时会抛出异常。使用的另一个原因WebDriverWait是等待“添加”按钮可单击。这是两个问题的解决方案，您可以使用try / catch来处理描述和“ customisable”元素的存在，并且可以等待“添加”按钮被单击：
