我沒有測試下面的實施例。
但我相信它舉了一個你想要的例子。
#include <v8.h>
using namespace v8;
int main(int argc, char* argv[]) {
// Create a handle scope
HandleScope handle_scope;
// Create a new context.
Handle<Context> context = Context::New();
// Enter the created context for compiling and
// running the script.
Context::Scope context_scope(context);
// Create a new script
const char* script = "function MyObj() { this.myArray = []; this.myDouble = 0; this.myFunction = function(arg1,arg2) { return (myDouble + arg1 + arg2); } } var globalObject = new myObj();"
// Create a string containing the JavaScript source code.
Handle<String> source = String::New("script);
// Compile the source code.
Handle<Script> script = Script::Compile(source);
// Running the script
// Run the script to get the result.
Handle<Value> scriptresult = script->Run();
// Convert the result to an ASCII string and print it.
String::AsciiValue ascii(scriptresult);
printf("%s\n", *ascii);
// Get the object
Handle<Object> object = Local::Cast(context->Global()->Get(String::New("globalObject")));
// Get the Properties
Handle<Value> arrayproperty = Handle::Cast(object->Get(String::New("myArray")));
Handle<Value> doubleproperty = Handle::Cast(object->Get(String::New("myDouble")));
String::AsciiValue ascii2(arrayproperty);
String::AsciiValue ascii3(doubleproperty);
printf("%s\n", *ascii2);
printf("%s\n", *ascii3);
// Call the function
Handle fun_to_call = Handle::Cast(object->Get(String::New("myFunction")));
int argcount = 0;
Handle argarray[] = NULL;
Handle functionresult = fun_to_call->Call(object, argcount, argarray);
// argcount and argarray are your standard arguments to a function
return 0;
}
至於如何修改數組,我相信它會使用
// Get the object
Handle<Object> object = Local::Cast(context->Global()->Get(String::New("globalObject")))1;
//Initialise array
int num[4] = {1,2,3,4};
v8::Local<v8::Array> arguments = v8::Array::New(num);
for (int i = 0; i < args; i++) {
arguments.Set(v8::Number::New(i), v8::String::New(args[i]));
}
// Set Array
object->Set(v8::String::New("myArray"), arguments);
