Question

我正在使用bootstrap模式显示登录或注册模式，我希望模式在一定时间后弹出，我希望模态只在他们注册或登录后关闭，基本上它需要在弹出后限制对网站的访问，所以他们被迫注册或者他们无法继续查看网站，我正在使用bootstrap.js，我可以从链接触发模态但我想要它在30秒后自动显示，请帮忙，不要用jquery，谢谢。

我的模态

您可以尝试以下方式：

$(document).ready(function() {
    setTimeout(function() {
      $('#myModal').fadeIn(200);
    }, 30000); // milliseconds
});

除此之外，我们还需要查看一些代码，以便更好地了解您的设置。

你真的不需要需要 jQuery（虽然jQuery可以轻松淡入/淡出）。纯JavaScript：

window.onload = function() {
  var modal = document.getElementById('myModal');

  setTimeout(function() {
    modal.style.display = 'block';
  }, 30000);
}

<强>更新

此外，您可以使用bootstrap的内置模态函数来显示/隐藏。只需创建一个新文件，例如 custom.js ，即可保存如下脚本：

$(document).ready(function() {
    setTimeout(function() {
      $('#myModal').modal('show');
    }, 30000); // milliseconds
});

超时后自动显示jquery模式
