python3 用execjs执行JS代码----调用JS方法和变量

​
import execjs
#读取js文件
with open('t.js',encoding='utf-8') as f:
    js = f.read()

#通过compile命令转成一个js对象
docjs = execjs.compile(js)

#调用function
res = docjs.call('createGuid')
print(res)

#调用变量
res = docjs.eval('guid')
print(res)

​

输出结果:

2e45
1efdfa41-4450-0302c2a6-fb959feef6a4

 

t.js 文件:

var createGuid = function() {
        return (((1 + Math.random()) * 65536) | 0).toString(16).substring(1)
    };

var guid = createGuid() + createGuid() + "-" + createGuid() + "-" + createGuid() + createGuid() + "-" + createGuid() + createGuid() + createGuid();

python2执行执行js文件使用pyv8
