Google chrome extension issue: popup.html interferes with script execution in background.html
I am learning how to extend Google chrome and I have run into the following problem:
I have the following manifest file:
{
"name": "My First Extension",
"version": "1.0",
"description": "The first extension that I made.",
"background_page": "background.html",
"browser_action": {
"default_icon": "icon.png",
开发者_如何学运维 "popup": "popup.html"
},
"permissions": [
"tabs",
"http://*/*",
"https://*/*"
]
}
My background.html file just injects some simple JavaScript into the page:
<script>
// Called when the user clicks on the browser action.
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.executeScript(null, {code:"alert(\"hi from background CODE\");"});
});
</script>
My popup.html file is just simple HTML:
<body>
Sup Playa
</body>
The dialog box from background.html never gets displayed. popup.html functions as expected.
However when I comment out popup.html from the manifest file, the script in background.html works.
What am I doing wrong? Why aren't both the dialog box and the popup showing up?
As it says in the docs:
onClickedevent will not fire if the browser action has a popup.
So if you assign any html file to your popup "popup": "popup.html" (rather than just a button without body), onClicked event isn't fired.
You can just put your code right into popup.html (it has same privileges as a background page) if you want something to be executed each time it is opened:
chrome.tabs.executeScript(null, {code:"alert(\"hi from background CODE\");"});
加载中,请稍侯......
