您需要输入有效的选项。我:e
show, hide or a callback function
。请参阅 - https://getbootstrap.com/docs/4.2/components/toasts/。
$('.toast').toast('show');

data-autohide="false"
。
$('.toast').toast('show')

文档准备好后,您需要启动“ $(".toast").toast('show'); 。
<script>
$(document).ready(function() {
$(".toast").toast('show');
});
</script>
首先,你需要将吐司固定在顶部或底部,具体取决于你想要的位置。
<div role="alert" aria-live="assertive" aria-atomic="true" class="toast fixed-bottom m-5 ms-auto"
data-bs-autohide="false">
<div class="toast-header">
<img src="..." class="rounded me-2" alt="...">
<strong class="me-auto">Bootstrap</strong>
<small>11 mins ago</small>
<button type="button" class="btn-close" data-bs-dismiss="toast" aria-label="Close"></button>
</div>
<div class="toast-body">
Hello, world! This is a toast message.
</div>
</div>
<script>
window.onload = (event) => {
let myAlert = document.querySelector('.toast');
let bsAlert = new bootstrap.Toast(myAlert);
setTimeout(function () {
bsAlert.show();
}, 5000);
};
</script>
我尝试了这个解决方案,但我收到一个 JS 错误“Uncaught ReferenceError: bootstrap is not Defined”,这似乎阻止了烤面包机的显示。
我看到的唯一区别是我正在使用 bootstrap5,并且 bootstrap 似乎不再需要 JQuery,因此它不包含在基本模板中。
渲染后我在基本模板中看到的是:
<head>
...

</body
我不知道为什么 bootstrap 是未定义的,因为 JS 是明确链接的,但我是 bootstrap 的新手,所以可能做了其他错误。我正在使用 django-bootstrap5 应用程序,其他一切似乎都工作正常。
可能想考虑使用这个库,它通过引导程序简化了 toast 的使用:
