使用Selenium和Python定位，在文本框中输入值

Question

<div class="MY_HEADING_A">
    <div class="TitleA">My title</div>
    <div class="Foobar"></div>
        <div class="PageFrame" area="W">                
             <span class="PageText">PAGE <input id="a1" type="txt" NUM="" />  of <span id="MAX"></span> </span>
</div>

我有上面的代码，我正在尝试使用selenium输入上面的NUM值这里是我写的代码：

head = driver.find_element_by_class_name("MY_HEADING_A")
frame_elem = head.find_element_by_class_name("PageText")

# Following is a pseudo code. 
# Basically I need to enter a value of 1, 2, 3 etc in the textbox field (NUM) 
# and then hit RETURN key.
## txt  = frame_elem.find_element_by_name("NUM")
## txt.send_keys(Key.4"

如何获取此元素并输入值？

Answer 1

假设您的页面在“http://example.com”下可用

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

按ID选择元素：

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

现在你可以模拟命中ENTER：

inputElement.send_keys(Keys.ENTER)

或者如果是您可以提交的表格：

inputElement.submit()
