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>
上述程序生成以下输出。
