import time

# open web-site
dr = webdriver.Firefox()
dr.get("http://61.163.88.227:8006/hwsq.aspx")
time.sleep(0.5)

# change calendar attribute
#  make it editable
js='document.getElementById("ContentLeft_menuDate1_TextBox11").removeAttribute("readonly")'
dr.execute_script(js)
#  change it with dynamic value
year = 2010
month = 1
date = 1
num1 = year*10000+month*100+date
print(str(num1))
js='document.getElementById("ContentLeft_menuDate1_TextBox11").setAttribute("value", num1 )'
dr.execute_script(js)

# update desired value
dr.find_element_by_id('ContentLeft_Button1').click()

dr.quit()

字符串拼接呗

'document.getElementById("ContentLeft_menuDate1_TextBox11").setAttribute("value", '+num1+')'
