[swathi jakkam]

Hi,

how to call the javascript methods from v8?

i wrote one function in javascript.I want call that function from
v8.could you please give the solution.

for example:I wrote the code in js file below:

function JS_fun(num) {
var JS_Dial = {};

JS_Dial.fun_name = "sum";
JS_Dial.phonenum = num;

var JSON_Str = JSON.stringify(JS_Dial);
print(JSON_Str);
}

here JS_fun() is implemented in javascript.i need how call this
JS_fun() from v8.


Regards,
swathi.

Depends on how do you get a function, you can get it from an argument then it would be:
v8::Local<v8::Value> func = args[x];

I think there is a way to get it from Global context too.

and if you have a function object you call it like that:
v8::Persistent<v8::Function> func = v8::Persistent<v8::Function>::Cast(obj);

v8::Handle<v8::Value> returnObj = func->Call(v8::Context::GetCurrent()->Global(),
                        <argcount>, <args>);
