<body style="width: 200px;" id="body">

        Enter New Word: <input type="text" name="newWord" id="new">
        <button type="submit" value="Change Word">CHange</button>
    </form>

</html>

popup.js

function replaceWord(){
chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
    chrome.tabs.sendMessage(tabs[0].id, {greeting: "hello"}, function(response) {
        console.log(response.value);
    });
});
}



document.addEventListener('DOMContentLoaded', function(){
    var form = document.getElementById('replaceWord');
    form.addEventListener('submit', function(){
        replaceWord();
    })
})

content_script.js

chrome.runtime.onMessage.addListener(function(response, sender, sendResponse){
    sendResponse({value : "hello"});
});

尝试从content_Script接收响应以弹出但不会这样做。在弹出窗口我有标签ID正确但我没有得到任何回应。为什么会这样？请帮助。

没有得到内容脚本的响应
