framePlainText 属性framePlainText 属性返回当前活动帧的内容，但只返回没有任何 HTML 标签的内容。
其语法如下：
var wpage = require('webpage').create();
wpage.framePlainText;
让我们举一个示例来理解 framePlainText 属性的用法。
var wpage = require('webpage').create();
wpage.open('http://localhost/tasks/content.html', function (status) {
console.log(status);
console.log(wpage.framePlainText);
phantom.exit();
});
content.html<html>
<head>
<title>welcome to phantomjs</title>
</head>
<body name = "content">
<script type = "text/javascript">
window.name = "page2";
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");
}
</script>
<iframe src = "http://localhost/tasks/a.html" width = "800" height = "800"
name = "myframe" id = "myframe"></iframe>
<h1>dddddddddd</h1>
</body>
</html>
它将产生以下输出。
success
dddddddddd
