Chrome 扩展程序不会从弹出文件中加载我的 JavaScript

2022-01-20 00:00:00 google-chrome popup jquery javascript html

我正在为论坛构建 Chrome 扩展程序，但问题是我的 popup.html 的 JavaScript 无法执行任何操作.我在顶部添加了 alert("popup.js running...") 并且它确实出现了，但是我的弹出窗口根本不显示.这是一个问题，因为弹出页面需要 JavaScript.我有点迷路了，所以我假设我只是错过了一些阻止我的 JavaScript 运行的东西.我听说 AdBlock 扩展程序会阻止它运行，但我删除了它，它仍然没有工作.有人看到问题了吗?

I'm working on building a Chrome extension for a forum, but the problem is the JavaScript for my popup.html won't do anything. I added alert("popup.js running...") at the top and it does come up but then my popup doesn't display at all. This is a problem because JavaScript is going to be required for the popup page. I'm kind of lost, so I'm assuming I'm just missing something that is preventing my JavaScript from running. I heard the AdBlock extension would prevent it from running but I removed that and it still didn't work. Anyone see a problem?

        <span id="output">[output]</span>
        <script type="text/javascript" src="popup.js"></script>
    </body>
</html>

popup.js

alert("popup.js running");
$(document).on("ready", function() {
    var siggy = $("#siggy");
    var output = $("#output");

    function message(text) {
        output.html(text);
    }

    siggy.change(function() {
        chrome.storage.sync.set({"siggy": siggy.val()}, function() {
            message("Saved signature.");
        });
    });

    message("Riggy is ready!");
});

我的扩展也遇到了同样的问题，我相信在我将它添加到清单文件后它已经解决了.

I had the same exact problem with an extension of mine, I believe it was fixed after I added this to the manifest file.

manifest.json

manifest.json

"content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'"
