selenium not setting input field value
提问by CracLock
Let's say we have this website https://www.coinichiwa.com/which has a BET AMOUNT input box. It's html is:
假设我们有这个网站https://www.coinichiwa.com/，它有一个 BET AMOUNT 输入框。它的 html 是：
<input autocomplete="off" id="betFa" name="a" maxlength="20" value="0.00000000" class="betinput" style="">
I need to add some value into it. Here is my code:
我需要为它添加一些价值。这是我的代码：
browser = webdriver.Firefox()
browser.get('https://www.coinichiwa.com')
browser.find_element_by_id("betFa").send_keys("0.00000005")
print browser.find_element_by_xpath("//input[contains(@id,'betFa')]").text
But it's neither setting it's value to "0.00000005" nor it printing the valueof input.
但它既没有将它的值设置为“0.00000005”，也没有打印value输入。
I'm not sure what's going wrong. Can you suggest? Why it's not working?
我不确定出了什么问题。你能建议吗？为什么它不起作用？

You need to clear()the text input first:
您需要先clear()输入文本：
bet_fa = browser.find_element_by_id("betFa")
bet_fa.clear()
bet_fa.send_keys("0.00000005")
As for the your second problem - this is an inputand the value you enter into it is kept inside the valueattribute, not the text. Use get_attribute()method:
至于你的第二个问题 - 这是一个input，你输入的值保存在value属性中，而不是文本中。使用get_attribute()方法：
browser.find_element_by_xpath("//input[contains(@id,'betFa')]").get_attribute('value')
