问题
I want to fire an event when a new tab is created in Chrome. I thought the following would do it, but it seems not. (beginner)
manifest.json
{
"name": "My First Extension",
"version": "1.0",
"description": "The first extension that I made.",
"background_page": "background.html",
"permissions": [
"tabs"
]
}
background.html
<html>
<head>
<script type="text/javascript">
chrome.tabs.onCreated.addListener(function() {alert('hello new tab'});
</script>
</head>
<body>
</body>
</html>
回答1:
Are you just missing a closing ) bracket?
...{alert('hello new tab'});
^
Because other than that your code works for me.
