PhantomJS - onPrompt()
当网页调用提示时,将调用此回调。它需要两个参数,message和answer。返回值是一个字符串。
语法
其语法如下 −
wpage.onPrompt = function(msg, defaultVal) {}
示例
以下代码显示了onPrompt()方法的使用。
var wpage = require('webpage').create(); wpage.onPrompt = function(msg, answer) { console.log("Entering in onPrompt callback"); console.log(msg); return answer; } wpage.open('http://localhost/tasks/prompt.html', function(status) { console.log(status); });
prompt.html
<html> <head> <title>Welcome to phantomjs</title> </head> <body> <script type = "text/javascript"> window.onload = function() { prompt("Is the page loaded", ""); } </script> <h1>This is a test page</h1> </body> </html>
上述程序生成以下输出。
Entering in onPrompt callback Is the page loaded Success
