How to interpret JavaScript with Python

It is possible to run JavaScript with开发者_C百科 Python? There are any library that makes this possible?

I need to execute some JavaScript, I know that this is possible with some Java libraries, but I prefer Python.

Can someone give me a clue on this?

Best Regards,

You can check spidermonkey

If you already use PyQt and QWebView in it, displaying custom html, the function evaluateJavaScript of QWebFrame may be useful for you:

# Python
def runJavaScriptText(self, jsText):
   jsText = 'hello()'  # just to fit javascript example
   self.webView.page().currentFrame().evaluateJavaScript(jsText)


// Javascript
function hello() {
    alert('hello');
};

Using spidermonkey would give you a tightier integration of your code, but as a workaround, you could make the javascript get run in a browser using Selenium remote-control:

http://seleniumhq.org/projects/remote-control/ (there are ways of doing that without needing a "physical" display for the browser, using VNC servers, for example)

Does it need to be CPython ?

And does the Javascript need a browser client environment ?

If not, you can probably call Rhino from Jython.

( Note also that Jython release is only at 2.5.2 )

Yes you can execute JavaScript from Python. I find the easiest way is through Python's bindings to the webkit library - here is an example. In my experience selenium and spidermonkey are harder to get working.
