我知道之前已经问过这个问题,但我不知道hwo能让它发挥作用。
这是内容脚本:
console.log("online");
chrome.extension.sendRequest({foo: "yes"}, function(response) {
console.log(response.thefoo);
});
这是背景页面:
chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
if (request.foo == "yes")
sendResponse({thefoo:"this is the foo"});
else
sendResponse({"it didnt work"});
});
我在这里的代码,它来自这里的一个已回答的问题,我做了一些更改,但即使我完全按照它也没有用。 你可以在这里看到答案Chrome extension: accessing localStorage in content script
答案 0 :(得分:1)
--- === background.html === ---
/*
* Handles data sent via chrome.extension.sendRequest().
* @param request Object Data sent in the request.
* @param sender Object Origin of the request.
* @param callbackFunction Function The method to call when the request completes.
*/
function onRequest(request, sender, callbackFunction) {
//your actions here
};
/*
* Add request listener
*/
chrome.extension.onRequest.addListener(onRequest);
--- === contentScript.js === ---
function callbackFunction(response) {
//process the response
}
chrome.extension.sendRequest({'action': 'your action'}, callbackFunction);
您还需要在清单文件中定义内容脚本
