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(&#39;sd&#39;, &#39;linuxany&#39;, &#39;/tmp&#39;)
    f2=tempfile.mktemp(&#39;sd&#39;, &#39;linuxany&#39;, &#39;/tmp&#39;)
                    
    fp=open(f,&#39;w&#39;)
    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=&#39;&#39;&#39;
    function dF(s,n){
        n=parseInt(n);
        var s1=unescape(s.substr(0,n)+s.substr(n+1,s.length-n-1));
        var t=&#39;&#39;;
        for(var i=0;i第2种方案Python-Spidermonkey 这个Python模块允许执行Javascript相关功能，是python与javascript之间进行操作的桥梁，javascript的类，对象和函数都可以在Python中调用。它大量借鉴了克拉斯Jacobssen的JavaScript Perl模块，而这又是Mozilla的PerlConnect Perl的结合为基础。安装：svn checkout http://python-spidermonkey.googlecode.com/svn/trunk/ python-spidermonkey-read-only下载完后，先运行python setup.py build然后运行python setup.py install官方网站：http://code.google.com/p/python-spidermonkey/同时需要安装Pyrex模块，一个支持python和C语言混编的模块。装完后就用python其他模块一样使用即可。
