How to execute a Javascript function in python with selenium
提问by Jose_Sunstrider
I have a function called 'checkdata(code)' in javascript, which, as you can see, takes an argument called 'code' to run and returns a 15-char string.
我在 javascript 中有一个名为“checkdata(code)”的函数，正如您所看到的，它接受一个名为“code”的参数来运行并返回一个 15 个字符的字符串。
So, I found out (and tested) how to call no-argument functions in javascript, but my problem is that when I call checkdata(code), I always get a 'none' return value. This is what I'm doing so far:
所以，我发现（并测试了）如何在 javascript 中调用无参数函数，但我的问题是当我调用 checkdata(code) 时，我总是得到一个“none”返回值。这是我目前正在做的事情：
wd = webdriver.Firefox()
wd.get('My Webpage')
a = wd.execute_script("return checkdata()", code) //Code is a local variable
//from my python script
print a
I'm making this, since I read it on an unofficial selenium documentation and here: link
我正在做这个，因为我在非官方 selenium 文档和这里阅读了它：链接
But, as I said before, I just keep getting none printed.
但是，正如我之前所说，我一直没有打印。
How can I call my function passing that parameter?
如何调用传递该参数的函数？

Build the string
构建字符串
a = wd.execute_script("return checkdata('" + code + "');")

Rather than building a string (which means you'd have to escape your quotes properly), try this:
而不是构建一个字符串（这意味着你必须正确地转义你的引号），试试这个：
a = wd.execute_script("return checkdata(arguments[0])", code)
