javascript - return evaluated javascript function to terminal

问题描述

I'm trying to return a function that has been evaluated to the terminal. I tried using window.onload(), console.log(); alert(); but the URL isn't evaluated and sent to the terminal.

I run the code below using the command phantomjs test.js

var webPage = require('webpage');
var page = webPage.create();

function testlink() {
  return(["h","t","t","p","s",":","\/","\/","i","b","m",".","c","o","m"]);
}

window.onload = testlink;
console.log(testlink);
alert(testlink);

Instead of getting (this is what I want)

https://ibm.com

I get 

function testlink() {
  return(["h","t","t","p","s",":","\/","\/","i","b","m",".","c","o","m"]);
}

Ps: I'm using Ubuntu 18.04 and phantomjs 2.1.1

解决方案

尝试做console.log(testlink())而不是console.log(testlink)

如果我们想加入该数组中的所有字符，只需返回：

["h","t","t","p","s",":","\/","\/","i","b","m",".","c","o","m"].join("")

或者，如果您不想更改功能，请执行console.log(testlink().join(""))
