问题描述
我找到了一个Chrome扩展程序WebNavigation API,但我不知道如何使用它.有人可以给我一个简单的例子吗?
I found a chrome extension WebNavigation API, but I don't know how to use it. Could someone give me a simple example?
API:
chrome.webNavigation.getFrame(object details, function callback)
如果我想在页面中获取iframe id和iframe的scr,我可以使用此API吗?
If I want to get iframe id and iframe's scr in a page, can I use this API ??
推荐答案
作为文档状态,需要传递tabId,processId,frameId ...
As the docs state, one needs to pass tabId, processId, frameId...
为了获得这些值,需要监听.onCompleted():
in order to get these values, one needs to listen for .onCompleted():
chrome.webNavigation.onCompleted.addListener(function(e){
chrome.webNavigation.getFrame(
{tabId: e.tabId, processId: e.processId, frameId: e.frameId},
function(details){
console.dir(details);
}
);
});
.getFrame()之前的事件属性已经为人所知
The event's properties are already known before the .getFrame()
