我正在尝试获取用户在数据库中创建的所有主板并将其弹出Chrome扩展程序 当我点击扩展名时,我看到空弹出窗口,但是当我在浏览器中运行extension.php时,它会显示预期的输出。 我是google扩展程序的新用户可以帮我这个吗?
答案 0 :(得分:1)
您没有将checkusername()
函数绑定到任何事件,因此它永远不会被执行
要解决此问题,请将以下行添加到popup.js
:
document.addEventListener('DOMContentLoaded', function() {
checkusername();
});
BTW,调试此类问题:
Network
标签。<子> (虽然“开发人员工具”面板保持打开状态,但弹出窗口也是如此,因此您可以在调试时与其他窗口/面板进行交互。) 子>
顺便说一下,你的}
还有一个额外的popup.js
(也没有任何帮助)。
