I'm building a web scraper using spookyjs: https://github.com/WaterfallEngineering/SpookyJS
I created a new spooky object and I'm trying to evaluate a function that returns the contents of a certain html tag. For the sake of readability I'm trying to use a function (returnDataFromSelector()) to do this each time. However when I pass the function through evaluate it returns null.
When I use an anonymous function it works correctly. How can I get the returnDataFromSelector function work correctly?
spooky.then(function() { function returnDataFromSelector(selector) { return function () { return document.querySelectorAll(selector)[0].innerHTML; } } var pageData = {}; pageData.projectName = this.evaluate(returnDataFromSelector('a.green-dark')); // returns null pageData.projectName = this.evaluate(function () { return document.querySelectorAll('a.green-dark')[0].innerHTML;}); // returns correct string this.emit('pageData', pageData); });
