单击popup.html上的按钮时运行background.js文件的简单方法

Question

I have been trying to run a function in my background.js file when I click a button on my popup.html file, I have tried a bunch of examples online and so far none of them have worked for me.

Here is what Ive tried:

$(".start-btn").click(function() {

    var task = loadTaskFromStorage($("#select-task").val());

    var checkbox = $('input[type="checkbox"]');
    var autobuy = $(checkbox).prop('checked');
    var delay = $("#checkout-ms").val();
    var count = localStorage.getItem('count');


    chrome.storage.sync.set({'task': task.cells, 'count': count}, function() {

    });

    chrome.storage.sync.set({'autobuy': autobuy, 'delay': delay}, function() {
    });

    chrome.runtime.sendMessage({'run': true);

then in the background.js file tried to do this:

chrome.runtime.onMessage.addListener(function(message, sender) {
  if(!message.run) return;

  finder();
});

function finder() {
    //pulling json info and opening url loop
});

I want to chrome.storage.sync.get all my things that I saved in my popup.js file then run the function.. I have tried a bunch of solutions and so far none of them have worked for me...

Thank you for helping me in advance <3!

popup.js :

Accumulate the data then send it over to the background:

$(".start-btn").click(function() {

    var task = loadTaskFromStorage($("#select-task").val());

    var checkbox = $('input[type="checkbox"]');
    var autobuy = $(checkbox).prop('checked');
    var delay = $("#checkout-ms").val();
    var count = localStorage.getItem('count');

    chrome.runtime.sendMessage({ run: true, data: {
        task: task.cells,
        count,
        autobuy,
        delay
    } });
}

background.js :

Retrieve the data sent over from the popup, store it and use it:

chrome.runtime.onMessage.addListener(function(message, sender) {
    if(!message.run) return;

    var data = message.data;
    chrome.storage.sync.set(data, function() { /* ... */ });
    console.log(data);
});
