Launch demo modal

</button>

<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>

<span aria-hidden="true">&times;</span>

</button>

</div>

...

</div>

<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>

</div>

Giải thích: Khi click vào button Launch demo modal thì popup xuất hiện. Bạn để ý cho mình đoạn code sau data-toggle="modal" data-target="#exampleModal"
Trong đó:
- data-target=”#exampleModal” là dùng để xác định popup nào được gọi (nếu có nhiều popup trên cùng trang), trong ví dụ trên là popup có id là #exampleModal
- data-toggle=”modal” là lệnh mở một Modal Popup trong Bootstrap
Phần popup các bạn muốn show ra là đoạn code này : Trong popup đó các bạn muốn thêm gì thì thêm hiện ứng ra sao tuỳ các bạn.

Giải thích Khi bạn muốn modal thứ 2 xuất hiện bạn chỉ cần. cho data-target=”id pop up bạn muốn show”. ví dụ trên data-target=”#exampleModal2″
Nhưng như thế chưa đủ. Khi hiện lên bạn sẽ thấy màu background overlay hiện ra đậm hơn. popup sau sẽ nằm tại popup đầu và nhìn như hình ảnh sau
Để sửa những lỗi vậy, mình pải làm sao. Đơn giản thôi bạn chỉ cần sửa như sau:

tại html ở popup2: thêm class : modal-second

</button>

</div>

...

</div>

<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>

</div>

tại css bạn thêm đoạn code sau:

<span class="token selector">.modal-second </span><span class="token punctuation">{</span>
  <span class="token property">z-index</span><span class="token punctuation">:</span> 1052<span class="token punctuation">;</span>
<span class="token punctuation">}</span>

<span class="token selector">.modal-backdrop.fade </span><span class="token punctuation">{</span>
  <span class="token selector"><span class="token parent important">&amp;</span> + .modal-backdrop.fade </span><span class="token punctuation">{</span>
    <span class="token property">z-index</span><span class="token punctuation">:</span> 1051<span class="token punctuation">;</span>
  <span class="token punctuation">}</span>
<span class="token punctuation">}</span>

.modal-second {

z-index: 1052;

}

.modal-backdrop.fade {

& + .modal-backdrop.fade {

z-index: 1051;

}

tại js bạn thêm đoạn code sau:

<span class="token function">$</span><span class="token punctuation">(</span>document<span class="token punctuation">)</span><span class="token punctuation">.</span><span class="token function">on</span><span class="token punctuation">(</span><span class="token string">'hidden.bs.modal'</span><span class="token punctuation">,</span> <span class="token keyword">function</span> <span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token punctuation">{</span>
      <span class="token keyword">if</span> <span class="token punctuation">(</span><span class="token function">$</span><span class="token punctuation">(</span><span class="token string">'.modal:visible'</span><span class="token punctuation">)</span><span class="token punctuation">.</span>length<span class="token punctuation">)</span> <span class="token punctuation">{</span>
        <span class="token function">$</span><span class="token punctuation">(</span><span class="token string">'body'</span><span class="token punctuation">)</span><span class="token punctuation">.</span><span class="token function">addClass</span><span class="token punctuation">(</span><span class="token string">'modal-open'</span><span class="token punctuation">)</span><span class="token punctuation">;</span>
      <span class="token punctuation">}</span>
    <span class="token punctuation">}</span><span class="token punctuation">)</span><span class="token punctuation">;</span>

$(document).on('hidden.bs.modal', function () {

if ($('.modal:visible').length) {

$('body').addClass('modal-open');

}

});

Thế là bạn đã hoàn thành modal multiple rồi.

Hướng dẫn làm Step modal

Step modal là sao: là cùng 1 popup khi bạn click vào button này sẽ chuyển đến modal sau với nội dụng khác với nội dung ban đầu.
Đầu tiên bạn cứ tạo 1 popup modal như bình thường

<span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>button</span> <span class="token attr-name">type</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>button<span class="token punctuation">"</span></span> <span class="token attr-name">class</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>btn btn-primary<span class="token punctuation">"</span></span> <span class="token attr-name">data-toggle</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>modal<span class="token punctuation">"</span></span> <span class="token attr-name">data-target</span><span class="token attr-value"><span class="token punctuation">=</span><span class="token punctuation">"</span>#exampleModal<span class="token punctuation">"</span></span><span class="token punctuation">&gt;</span></span>
