我需要传递变量,但不能工作
php
exec('phantomjs screenshot.js http://www.google.com google.png');
js
var args = require('system').args;
var page = require('webpage').create();
var address = system.args[1];
var image = system.args[2];
page.open(address , function () {
page.render(image);
phantom.exit();
});
如果我在没有php的情况下运行脚本,我就有
phantomjs screenshot.js http://google.com google.com
0: screenshot.js
1: http://google.com
2: google.com
ReferenceError: Can't find variable: system
Phantomjs找不到system
变量,因为它未定义。
你需要写任一
var args = require('system').args;
var address = args[1];
var image = args[2];
或者你可以写
var system = require('system');
var address = system.args[1];
var image = system.args[2];
