Pyv8 learn python and JavaScript variables for interaction _python

Python Gets the value in JavaScript

Copy Code code as follows:

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 gets the value inside python

Copy Code code as follows:

Import PyV8

With Pyv8.jscontext () as ENV1:
Env1.securitytoken = "Foo"
Env1.locals.prop = 3
print int (env1.eval ("prop"))

function interaction in Python and JavaScript

Python calls the functions in JavaScript Python calls Func can use the function functions in JS

Copy Code code as follows:

Import PyV8

with Pyv8.jscontext () as Ctxt:
    func = Ctxt.eval (""
                 (function ()
                 {
                     function A ()
                     {
                          return "ABC";
                    }

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

That's OK.

Copy Code code as follows:

Import PyV8

with Pyv8.jscontext () as Ctxt:
    func = Ctxt.eval (""
                     function A ()
                     {
                         return "ABC";
                    }

Function C ()
{
Return "ABC";
}
""")
A = CTXT.LOCALS.A
Print a ()
