Question

我一直在寻找解决这个问题的方法，但没有运气。

我正在使用selenium和BeautifulSoup4。

我将container_number变量传递给这个函数：

container_number="120001"

当我这样做时，找不到存储在container_number中的值（这对我没有意义）。变量container_number等于120001。但是，如果我通过编写browser = webdriver.Firefox() def change_location(number): #print number soup=bs(browser.page_source, 'html.parser') found = len(soup.find_all(text=re.compile("Indefinite"))) if found>1: indef=soup.find_all(text=re.compile("Indefinite")) indef.pop(0) for items in indef: temp = items.findPrevious('a') #print temp container_number=temp.find(text=True) print container_number print type(container_number) container_number=str(container_number) print type(container_number) print container_number #container_number="120001" if i uncomment this line it works find_container_number=wait.until(EC.presence_of_element_located((By.LINK_TEXT,container_number)))将container_number设置为120001 它运作得很好。

以下是我的相关代码：

120001
<class 'bs4.element.NavigableString'>
<type 'str'>
120001
Traceback (most recent call last):
  File ".\complete.py", line 86, in <module>

运行我的脚本时，这是我的输出。

<aside>
  <div>
     <p>I WANT TO BE DIV</p>
  </div>
    <div>
     <p>I WANT TO BE DIV</p>
  </div>
</aside>

aside{
  width: 100px;
  height: 300px;
  border: 1px solid blue;
  color:black;
}
div{
  width: 100px;
  height: 100px
}

这是猜测，但您可能需要在使用之前修剪值：

container_number = temp.find(text=True).strip()
find_container_number = wait.until(EC.presence_of_element_located((By.LINK_TEXT,container_number)))

或者，只需使用.get_text()：

temp = items.findPrevious('a')
container_number = temp.get_text(strip=True)

Selenium Python Binding不能将变量传递给函数
