How to use webpage - 10 common examples

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

var url = 'http://www.17qingsong.com/news/8JTND98F00964JJM';

page.viewportSize = {width: 1170, height: 7824};

page.open(url, function (status) {
    // var height = page.evaluate(function() { return document.body.clientHeight; });
    // var width = page.evaluate(function() { return document.body.clientWidth; });
    // console.log(height);
    // page.viewportSize = {width: 1170, height: height};
    page.render('17.jpg');
    // page.render('17.pdf');
    phantom.exit();
});

var page = require('webpage').create(), system = require('system'), address, output;
//viewportSize being the actual size of the headless browser
page.viewportSize = { width: 1024, height: 768 };
//the clipRect is the portion of the page you are taking a screenshot of
page.clipRect = { top: 192, left: 256, width: 512, height: 384 };
//the rest of the code is the same as the previous example
address = system.args[1];
output = system.args[2];
page.settings.resourceTimeout = 10000; // Avoid freeze!!!
page.open(address, function() {
window.setTimeout(function () {
                page.render(output);
                phantom.exit();
            }, 2000);
});

  }
  // Uncomment this to see console.log calls from within pages.

  //   console.log(info);
  // };
