问题描述
我知道这个问题以前曾被问过,但我不知道hwo是否能够正常工作。
这是内容脚本:
console.log(online);
chrome.extension.sendRequest({foo:yes},function(response){
console.log(response.thefoo);
});
这是后台页面:
chrome.extension.onRequest.addListener(function(request,sender,sendResponse){
if(request.foo ==yes)
sendResponse({thefoo :this is the foo});
else
sendResponse({it does not work});
});
我在这里得到的代码,它来自这里的一个回答问题,我做了,但即使当我把它完全没有工作。
您可以在这里看到
--- === background.html === ---
/ *
*处理通过chrome.extension.sendRequest()发送的数据。
* @param请求在请求中发送的对象数据。
* @param sender对象请求的来源。
* @param callbackFunction功能请求完成时调用的方法。
* /
函数onRequest(request,sender,callbackFunction){
//您在此处的动作
};
$ b $ *
*添加请求侦听器
* /
chrome.extension.onRequest.addListener(onRequest);
== === contentScript.js === ---
函数callbackFunction(response){
//处理响应
}
chrome.extension。 sendRequest({'action':'your action'},callbackFunction);
您还需要在清单文件中定义内容脚本
i know this question has been asked before but i dont know hwo to make it work.
this is the content script:
console.log("online");
chrome.extension.sendRequest({foo: "yes"}, function(response) {
console.log(response.thefoo);
});
and this is the background page:
chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
if (request.foo == "yes")
sendResponse({thefoo:"this is the foo"});
else
sendResponse({"it didnt work"});
});
the code that i have here, its from one of the answered questions around here with a few changes that i made, but it didnt work even when i put it exactly.you can see that answer here Chrome extension: accessing localStorage in content script
---=== 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);
you also need to have the content script defined in the manifest file
