我在一个工作示例应用程序(pageAction)中添加了click事件监听器,但我不知道哪里出了问题。看看这个文件中的2个:
我的清单json
{
"name" : "Page action by content",
"version" : "1.1",
"description" : "Shows a page action for HTML pages containing a video",
"background" : {
"scripts": ["background.js"],
"persistent": false
},
"page_action" :
{
"default_icon" : "video-19.png",
"default_title" : "There's a <video> in this page!"
},
"permissions": [ "declarativeContent" ],
"icons" : {
"48" : "video-48.png",
"128" : "video-128.png"
},
"manifest_version": 2
}
background js
chrome.runtime.onInstalled.addListener(function() {
chrome.declarativeContent.onPageChanged.removeRules(undefined, function() {
chrome.declarativeContent.onPageChanged.addRules([{
conditions: [
// When a page contains a <video> tag...
new chrome.declarativeContent.PageStateMatcher({
css: ["video"]
})
],
// ... show the page action.
actions: [new chrome.declarativeContent.ShowPageAction() ]
}]);
});
});
chrome.pageAction.onClicked.addListener(function(tab) {
console.log('Turning ' + tab.url + ' red!');
chrome.tabs.executeScript({
code: 'document.body.style.backgroundColor="red"'
});
});
我甚至将click函数放在chrome.runtime中,没有任何反应。我不认为我忘记重新加载扩展包。
