2 solutions for executing js in Python

The first option

SpiderMonkey is part of the Mozilla project and is a JavaScript script engine implemented in C language. The engine analyzes, compiles and executes scripts, and performs memory allocation and release operations according to the needs of JS data types and objects; use This engine gives your application the ability to interpret JavaScript scripts.

To use spidermonkey, you must install it first. The method is as follows:

cd /home/linuxany.com/

wget http://ftp.mozilla.org/pub/mozilla.org/js/js-1.7.0. tar.gz -O- | tar xvz

cd js/src

make -f Makefile.ref

mkdir -p /usr/include/smjs/ -v

cp *.{h,tbl} /usr/ include/smjs/ -v

cd Linux_All_DBG.OBJ

cp *.h /usr/include/smjs/ -v

mkdir -p /usr/local/{bin,lib}/ -v

cp js / usr/local/bin/ -v

cp libjs.so /usr/local/lib/ -v

After the above installation is completed, run /usr/local/bin/js and you should be able to start the js interpretation running engine.

Python usage example:

# coding:utf-8
import os
import tempfile
def call_js(js):
    f=tempfile.mktemp('sd', 'linuxany', '/tmp')
    f2=tempfile.mktemp('sd', 'linuxany', '/tmp')
                    
    fp=open(f,'w')
    fp.write(js)
    fp.close()
                    
    cmd="/usr/local/bin/js  %s > %s" % (f,f2)
                    
    os.system(cmd)
    result=open(f2).read()
    print result
if __name__ == "__main__":
    code='''
    function dF(s,n){
        n=parseInt(n);
        var s1=unescape(s.substr(0,n)+s.substr(n+1,s.length-n-1));
        var t='';
