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
