我创建了一个小js脚本,当其中将打印一些内容时,它允许我从控制台消息中弹出:
<!doctype html>
<html lang="en" xmlns="http://www.w3.org/1999/html">
<head>
<meta charset="utf-8">
<title>Frontend</title>
<base href="/">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
(function() {
var exLog = console.log;
console.log = function(msg) {
exLog.apply(this, arguments);
alert(msg);
}
})()
</script>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
</head>
<body>
<app-root></app-root>
</body>
</html>
但是功能只能执行一次,每次在控制台中发生某种情况时如何执行该功能?
