			<p style="text-align: justify;">Toast cũng là một thành phần thú vị, giống như thông báo trên web, ứng dụng. Dưới đây là&nbsp;<strong>cách tạo toast trong Bootstrap 5</strong>.</p>

<h2 style="text-align: justify;">Toast trên web là gì?</h2>

<p style="text-align: justify;">Toast là thành phần giống như một box cảnh báo nhưng chỉ hiện một vài giây khi điều gì đó xảy ra. Ví dụ: Khi người dùng click vào một nút bấm, gửi một biểu mẫu…</p>

<h2 style="text-align: justify;">Cách tạo toast trong Bootstrap 5</h2>

<p style="text-align: justify;">Để tạo toast, dùng class&nbsp;<code>.toast</code>&nbsp;cộng thêm&nbsp;<code>.toast-header</code>&nbsp;và&nbsp;<code>.toast-body</code>&nbsp;vào bên trong nó.</p>

<p style="text-align: justify;">Lưu ý: Toast mặc định bị ẩn. Dùng class&nbsp;<code>.show</code>&nbsp;nếu bạn muốn hiển thị nó. Để đóng nó, dùng phần tử&nbsp;<strong>&lt;button&gt;</strong>&nbsp;và thêm&nbsp;<code>data-bs-dismiss=&quot;toast&quot;</code>:</p>

<pre id="pre0" style="text-align: justify;">
&lt;div class=&quot;toast show&quot;&gt;
&lt;div class=&quot;toast-header&quot;&gt;
Toast Header
&lt;button type=&quot;button&quot; class=&quot;btn-close&quot; data-bs-dismiss=&quot;toast&quot;&gt;&lt;/button&gt;
&lt;/div&gt;
&lt;div class=&quot;toast-body&quot;&gt;
Some text inside the toast body
&lt;/div&gt;
&lt;/div&gt;</pre>

<p style="text-align: justify;">Ví dụ:</p>

<pre id="pre1" style="text-align: justify;">
&lt;!DOCTYPE html&gt;
&lt;html lang=&quot;en&quot;&gt;
&lt;head&gt;
  &lt;title&gt;Bootstrap Example&lt;/title&gt;
  &lt;meta charset=&quot;utf-8&quot;&gt;
  &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1&quot;&gt;
  &lt;link href=&quot;https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/css/bootstrap.min.css&quot; rel=&quot;stylesheet&quot;&gt;
  &lt;script src=&quot;https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js&quot;&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class=&quot;container mt-3&quot;&gt;
  &lt;h3&gt;Ví dụ về toast trên Quantrimang.com&lt;/h3&gt;
  &lt;p&gt;Toast giống như một box thông báo nhanh, chỉ hiện trong vài giây khi tác vụ nào đó xảy ra.&lt;/p&gt;
  &lt;p&gt;Ví dụ này dùng .show để mặc định luôn hiện toast. Đóng nó bằng cách click vào dấu x trong header toast.&lt;/p&gt;
  &lt;div class=&quot;toast show&quot;&gt;
    &lt;div class=&quot;toast-header&quot;&gt;
      &lt;strong class=&quot;me-auto&quot;&gt;QuanTriMang.com&lt;/strong&gt;
      &lt;button type=&quot;button&quot; class=&quot;btn-close&quot; data-bs-dismiss=&quot;toast&quot;&gt;&lt;/button&gt;
    &lt;/div&gt;
    &lt;div class=&quot;toast-body&quot;&gt;
      &lt;p&gt;Kênh thông tin công nghệ hàng đầu tại Việt Nam&lt;/p&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;/body&gt;
&lt;/html&gt;

<p style="text-align: justify;"><img alt="Toast trong Bootstrap" data-i="0" data-src="https://st.quantrimang.com/photos/image/2022/12/06/bootstrap-toast-3.gif" data-was-processed="true" height="284" src="https://st.quantrimang.com/photos/image/2022/12/06/bootstrap-toast-3.gif" width="555" /></p>

<h2 style="text-align: justify;">Mở một toast</h2>

<p style="text-align: justify;">Để hiện cảnh báo nhanh dạng toast bằng một click vào nút bấm, bạn phải khởi chạy nó với JavaScript: chọn phần tử đã chỉ định và gọi phương pháp&nbsp;<strong>toast()</strong>.</p>

<p style="text-align: justify;">Code sau sẽ hiện tất cả toast trong tài liệu khi bạn click vào một nút bấm:</p>

<pre id="pre2" style="text-align: justify;">
&lt;script&gt;
document.getElementById(&quot;toastbtn&quot;).onclick = function() {
var toastElList = &#91;&#93;.slice.call(document.querySelectorAll(&#039;.toast&#039;))
var toastList = toastElList.map(function(toastEl) {
return new bootstrap.Toast(toastEl)
})
toastList.forEach(toast =&gt; toast.show())
}
&lt;/script&gt;</pre>

<p style="text-align: justify;">Ví dụ:</p>

<pre id="pre3" style="text-align: justify;">
&lt;!DOCTYPE html&gt;
&lt;html lang=&quot;en&quot;&gt;
&lt;head&gt;
  &lt;title&gt;Bootstrap Example&lt;/title&gt;
  &lt;meta charset=&quot;utf-8&quot;&gt;
  &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1&quot;&gt;
  &lt;link href=&quot;https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/css/bootstrap.min.css&quot; rel=&quot;stylesheet&quot;&gt;
  &lt;script src=&quot;https://cdn.jsdelivr.net/npm/bootstrap@5.2.3/dist/js/bootstrap.bundle.min.js&quot;&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;

&lt;div class=&quot;container mt-3&quot;&gt;
  &lt;h3&gt;Ví dụ về toast&lt;/h3&gt;
  &lt;p&gt;Ví dụ này dùng nút bấm để hiện toast.&lt;/p&gt;

  &lt;button type=&quot;button&quot; class=&quot;btn btn-primary&quot; id=&quot;toastbtn&quot;&gt;Hiện Toast&lt;/button&gt;
  &lt;div class=&quot;toast&quot;&gt;
    &lt;div class=&quot;toast-header&quot;&gt;
      &lt;strong class=&quot;me-auto&quot;&gt;Quantrimang.com&lt;/strong&gt;
      &lt;button type=&quot;button&quot; class=&quot;btn-close&quot; data-bs-dismiss=&quot;toast&quot;&gt;&lt;/button&gt;
    &lt;/div&gt;
    &lt;div class=&quot;toast-body&quot;&gt;
      &lt;p&gt;Chào mừng bạn tới QuanTriMang.com&lt;/p&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;script&gt;
document.getElementById(&quot;toastbtn&quot;).onclick = function() {
  var toastElList = &#91;&#93;.slice.call(document.querySelectorAll(&#039;.toast&#039;))
  var toastList = toastElList.map(function(toastEl) {
    return new bootstrap.Toast(toastEl)
  })
  toastList.forEach(toast =&gt; toast.show()) 
}
&lt;/script&gt;

&lt;/body&gt;
&lt;/html&gt;
</pre>
