从python调用Javascript

Question

I am looking for a way to call a js function from a python function. I am coming to you because I also need my js function to use DOM, so pyv8 for example is not a solution.. Do you guys have any idea? Is it even possible?

Thanks in advance.

Answer 1

PyExecJS seems to be a good option.

>>> import execjs
>>> execjs.eval("'red yellow blue'.split(' ')")
['red', 'yellow', 'blue']
>>> ctx = execjs.compile("""
...     function add(x, y) {
...         return x + y;
...     }
... """)
>>> ctx.call("add", 1, 2)

to install:

$ pip install PyExecJS

According to https://stackoverflow.com/a/30537286/6353933 ,

import js2py

js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
}
escramble_758()
""".replace("document.write", "return ")

result = js2py.eval_js(js)  # executing JavaScript and converting the result to python string 

Advantages of Js2Py include portability and extremely easy integration with python (since basically JavaScript is being translated to python).

To install:

pip install js2py
