示例
实现在Yahoo上搜索:
var Nightmare = require('nightmare'); new Nightmare() .goto('http://yahoo.com') .type('input[title="Search"]', 'github nightmare') .click('.searchsubmit') .run(function (err, nightmare) { if (err) return console.log(err); console.log('Done!'); }); Or, let's extract the entirety of Kayak's home page after everything has rendered:
var Nightmare = require('nightmare'); new Nightmare() .goto('http://kayak.com') .evaluate(function (page) { return document.documentElement.innerHTML; }, function (res) { console.log(res); }) .run(); Or, here's how you might automate a nicely abstracted login + task on Swiftly:
var Nightmare = require('nightmare'); var Swiftly = require('nightmare-swiftly'); new Nightmare() .use(Swiftly.login(email, password)) .use(Swiftly.task(instructions, uploads, path)) .run(function(err, nightmare){ if (err) return fn(err); fn(); });
