在回调函数中为Chrome扩展图标设置动画,可以通过以下步骤实现:
- 首先,在Chrome扩展的manifest.json文件中,添加一个浏览器操作(browser_action),并设置一个默认图标和一个动画图标。例如:{
"name": "My Extension",
"version": "1.0",
"manifest_version": 3,
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "My Extension",
"action": {
"default_icon": {
"16": "icon16.png",
"32": "icon32.png"
},
"default_title": "My Extension",
"actions": [
{
"title": "Action 1",
"default_icon": {
"16": "action1_icon16.png",
"32": "action1_icon32.png"
},
"default_title": "Action 1"
},
{
"title": "Action 2",
"default_icon": {
"16": "action2_icon16.png",
"32": "action2_icon32.png"
},
"default_title": "Action 2"
}
]
}
},
"icons": {
"16": "icon16.png",
"32": "icon32.png"
},
"background": {
"service_worker": "background.js"
},
"permissions": [
"tabs"
]
}chrome.browserAction.onClicked.addListener((tab) => {
// 设置动画图标
chrome.browserAction.setIcon({
tabId: tab.id,
path: {
"16": "action1_icon16.png",
"32": "action1_icon32.png"
}
});
});<!DOCTYPE html>
<html>
<head>
<title>My Extension</title>
</head>
<body>
<button id="setIconButton">Set Icon</button>
<script src="popup.js"></script>
</body>
</html>// popup.js
document.getElementById("setIconButton").addEventListener("click", () => {
// 设置动画图标
chrome.browserAction.setIcon({
tabId: chrome.tabs.TAB_ID_NONE,
path: {
"16": "action1_icon16.png",
"32": "action1_icon32.png"
}
});
});通过以上步骤,可以在回调函数中为Chrome扩展图标设置动画。
- 在background.js文件中,监听浏览器操作的点击事件,并在回调函数中设置动画图标。例如:
- 在popup.html文件中,添加一个按钮,并在点击事件中调用浏览器操作的setIcon方法,设置动画图标。例如:
