通信
箱内和向外相互通信。
Sandboxed code:
onmessage = function(message){
if (message === 'hello from outside') {
postMessage('hello from inside');
}
};
Sandbox:
var sandbox = new Sandbox();
sandbox.run(sandboxed_code);
sandbox.on('message', function(message){
// Handle message sent from the inside
// In this example message will be 'hello from inside'
});
sandbox.postMessage('hello from outside');
// Example 11 - IPC Messaging s.run( "onmessage = function(message){ if (message === 'hello from outside') { postMessage('hello from inside'); };", function(output){ }) s.on('message', function(message){ console.log("Example 11: received message sent from inside the sandbox '" + message + "'\n") }); var test_message = "hello from outside"; console.log("Example 11: sending message into the sandbox '" + test_message + "'"); s.postMessage(test_message);
