是否可以将带有子元素的 html 元素保存为 JS 变量，您可以动态地将 append 保存到 DOM 中？

Question

I have this form snippet

<div id="form-container" class="row">
       <select style="width:250px;" name="drug_pack_size" id="drug_pack_size" class="form-control">
         <option value="">Selling Unit</option>
         <option value="Ampoule">Ampoule</option>
       </select>
       <span class="d-flex">
         <p class="mx-3">contains</p>
         <input type="text" class="form-control">
       </span>
       <span class="d-flex">
         <p class="mx-3">for</p>
         <input type="text" class="form-control">
         <p class="mx-3">GHC</p>
       </span>
     </div> 

Is it possible to do something like this

const form = document.querySelector('#form-element').content

Such that you can append it repeatedly and dynamically with JS code, without writing everything from the JS Backend

Answer 1

Yes, it is possible. Please try

 var x = document.getElementById("form-container").outerHTML;
 window.alert(x);

After this capture, if you want to repeatedly add same parent Element, then include variable(s) to increment the id and/or name of the parent and child elements to prevent duplication. For example, id="form-container1" , id="form-container2" , id="form-container3" , and so on.
