PhantomJS - ownsPages 属性
ownsPages 属性检查网页打开的页面是否是其子页面。因此,它返回 true 或 false。
语法
其语法如下 −
var wpage = require('webpage').create(); wpage.ownsPages
示例
让我们举一个例子来了解 ownsPages 属性的用法。
var wpage = require('webpage').create(); wpage.open('http://localhost/tasks/page1.html', function (status) { console.log(wpage.ownsPages); phantom.exit(); });
page1.html
<html> <head> <title>Testing PhantomJs</title> </head> <body> <script type = "text/javascript"> console.log('welcome to cookie example'); document.cookie = "username = Roy; expires = Thu, 22 Dec 2017 12:00:00 UTC"; window.onload = function() { console.log("page is loaded"); window.open("http://localhost/tasks/a.html","page1"); } </script> <h1>This is a test page</h1> </body> </html>
