Chrome 扩展消息传递 - 包含代码

发布于 2024-11-04 13:59:13 字数 692 浏览 0 评论 0原文

我有一个名为 file.js 的内容脚本，它创建变量“found”。我想将变量“found”的值发送到

file.js 中 popup.html 中的文本框（我知道变量找到正在工作，使用警报进行了测试）。

chrome.extension.sendRequest({foundlinks: found}, function(response) {
 console.log(response);
});

在 Popup.html 中：

function pulllinks(){

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {

    document.getElementById("box").value = request.foundlinks;

  sendResponse({});
});

以及在 popup.html 中的表单上：

<input type = "button" onclick="pulllinks();" name = "box" id="box" value = "Grab Links From Page"  />

但是，它没有执行任何操作。有什么想法吗？

谢谢！

I have a contentscript called file.js that creates variable "found". I want to send the values of varibale "found" to a textbox in popup.html

In file.js (I know varible found is working, tested using an alert).

chrome.extension.sendRequest({foundlinks: found}, function(response) {
 console.log(response);
});

In Popup.html:

function pulllinks(){

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {

    document.getElementById("box").value = request.foundlinks;

  sendResponse({});
});

And on the form in popup.html:

<input type = "button" onclick="pulllinks();" name = "box" id="box" value = "Grab Links From Page"  />

However, its not doing anything. Any ideas?

Thanks!

您需要以相反的方向发送请求 - 从弹出窗口到内容脚本：

popup.html:

function pulllinks(){
    chrome.tabs.getSelected(null, function(tab) {
        chrome.tabs.sendRequest(tab.id, {cmd: "findLinks"}, function(response) {
            document.getElementById("box").value = response.foundlinks;
        });
    });

}

file.js:

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
    if(request.cmd == "findLinks") {
        //calculate "found" value and send it back
        sendResponse({foundlinks: found});

    }
});

You need to be sending requests in the opposite direction - from popup to content script:

popup.html:

function pulllinks(){
    chrome.tabs.getSelected(null, function(tab) {
        chrome.tabs.sendRequest(tab.id, {cmd: "findLinks"}, function(response) {
            document.getElementById("box").value = response.foundlinks;
        });
    });

}

file.js:

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
    if(request.cmd == "findLinks") {
        //calculate "found" value and send it back
        sendResponse({foundlinks: found});

    }
});
