""" This module allows you to translate and execute Javascript in pure python.
|
||
|
|
Basically its implementation of ECMAScript 5.1 in pure python.
|
||
|
|
|
||
|
|
Use eval_js method to execute javascript code and get resulting python object (builtin if possible).
|
||
|
|
|
||
|
|
EXAMPLE:
|
||
|
|
>>> import js2py
|
||
|
|
>>> add = js2py.eval_js('function add(a, b) {return a + b}')
|
||
|
|
>>> add(1, 2) + 3
|
||
|
|
6
|
||
|
|
>>> add('1', 2, 3)
|
||
|
|
u'12'
|
||
|
|
>>> add.constructor
|
||
|
|
function Function() { [python code] }
|
||
|
|
|
||
|
|
|
||
|
|
Or use EvalJs to execute many javascript code fragments under same context - you would be able to get any
|
||
|
|
variable from the context!
|
||
|
|
|
||
|
|
>>> js = js2py.EvalJs()
|
||
|
|
>>> js.execute('var a = 10; function f(x) {return x*x};')
|
||
|
|
>>> js.f(9)
|
||
|
|
81
|
||
|
|
>>> js.a
|
||
|
|
10
|
||
|
|
|
||
|
|
Also you can use its console method to play with interactive javascript console.
|
||
|
|
|
||
|
|
|
||
|
|
Use parse_js to parse (syntax tree is just like in esprima.js) and translate_js to trasnlate JavaScript.
|
||
|
|
|
||
|
|
Finally, you can use pyimport statement from inside JS code to import and use python libraries.
|
||
|
|
|
||
|
|
>>> js2py.eval_js('pyimport urllib; urllib.urlopen("https://www.google.com")')
|
||
|
|
|
||
|
|
NOTE: This module is still not fully finished:
|
||
|
|
|
||
|
|
Date and JSON builtin objects are not implemented
|
||
|
|
Array prototype is not fully finished (will be soon)
|
||
|
|
|
||
|
|
Other than that everything should work fine.
