pyv8学习python和javascript变量进行交互

yipeiwu_com5年前 (2020-03-06)Python基础

python取得javascript里面的值

import PyV8

with PyV8.JSContext() as env1:
    env1.eval("""
                var_i = 1;
                var_f = 1.0;
                var_s = "test";
                var_b = true;
            """)
    vars = env1.locals
    var_i = vars.var_i
    print var_i

javascript取得python里面的值

复制代码代码如下:

import PyV8

with PyV8.JSContext() as env1:
    env1.securityToken = "foo"
    env1.locals.prop = 3
    print int(env1.eval("prop"))

python和javascript里面的函数交互

python调用javascript里面的函数 python调用func就可以使用js里面的function函数了

复制代码代码如下:

import PyV8

with PyV8.JSContext() as ctxt:
    func = ctxt.eval("""
                (function ()
                {
                    function a()
                    {
                        return "abc";
                    }

                    return a();
                })
                """)
    print func()

这样也可以

复制代码代码如下:

import PyV8

with PyV8.JSContext() as ctxt:
    func = ctxt.eval("""
                    function a()
                    {
                        return "abc";
                    }

                    function c()
                    {
                        return "abc";
                    }
                """)
    a = ctxt.locals.a
    print a()
