[英]Send message with ID of checked checkbox from popup.js to background.js
I want to send an ID of the checked checkbox from popup.js to background.js.我想将选中复选框的 ID 从 popup.js 发送到 background.js。 I tried it on the following way, but failed:我按以下方式尝试过,但失败了:
popup.html弹出窗口.html
<form id="cbx">
<label for="cb1">G</label>
<input name="cb1" type="checkbox">
<input type="submit" value="Submit">
popup.js弹出窗口.js
document.getElementById('cbx').addEventListener(
'submit', function checkForm(event) {
event.preventDefault();
//Define the form element
var form = document.getElementById("cbx");
if (form.cb1.checked) {
chrome.runtime.sendMessage({greeting: "cb1"});
}
return true;
});
background.js背景.js
chrome.extension.onMessage.addListener(function (request, sender, sendResponseParam) {
if( request.greeting === "cb1" ){
console.log("cb1");
}
})
After checking of the checkbox console remains empty.检查复选框后控制台仍然为空。 How can i handle this correctly?我该如何正确处理?
finally got in on this way:终于走上了这条路:
popup.js: popup.js:
if (form.cb1.checked) {
chrome.runtime.sendMessage({greeting: "cb1"}, function(response) {
return true;
});
}
background.js背景.js
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
if (request.greeting == "cb1"){
sendResponse();
console.log(request.greeting);
var action_url = "http://www.google.com/";
chrome.tabs.create({ url: action_url });
}
});
