Question

我正在使用以下javascript代码：

document.getElementsByName("commit")[0].click();

要单击按钮，问题是当我发送命令时，有时页面未加载，因此无法单击。那么，我如何才能执行点击，直到实际发生？我已经尝试过这样的事情：

if (document.readyState === 'complete') { //don't work
document.getElementsByName("commit")[0].click();

}

但是它不起作用。（我无法使用jquery，因为我使用的是chrome扩展程序）

Answer 1

在DOMContentLoaded事件中触发它应该可以解决问题

document.addEventListener('DOMContentLoaded', function() {
    document.getElementsByName("commit")[0].click();
})

我还要确保您将javascript文件放在页面底部而不是顶部。

尝试以下代码：

document.querySelector('#myBtn').addEventListener('click', function () {
 // do some stuff here
});

单击直到实际单击该元素
