如何知道当vm.runInContext完成它的执行时

Question

这是我的代码

var offer = {title:'fdsfds',price:323,value:140};
    var initSandbox = {
            http: http,
            offer: offer
        };
var context = vm.createContext(initSandbox);
vm.runInContext(code, context);

当runIncontext在提供的上下文成功地执行代码,它更新报价对象在上下文中,所以我需要知道它完成它的执行,所以我可以从上下文retrive报价对象时.

将回调传递给您的上下文并从您的代码中触发它

var vm = require('vm');
var offer = {title:'fdsfds',price:323,value:140};
var initSandbox = {
    http: 123,
    offer: offer,
    done : function(offer) {
        console.log('done!');
    },
    setTimeout: setTimeout
};
var context = vm.createContext(initSandbox);
vm.runInContext("setTimeout(done,100)", context);
