What is the best way to duplicate input fields without causing any issues with unique IDs?

My challenge involves an input form connected to an element that dynamically changes the properties of its children. I am seeking a solution to duplicate or clone this element along with its input form. Currently, I am utilizing element.cloneNode(true) to achieve this duplication.

However, the method I'm using is not producing the desired outcome as the inputs are radio buttons, each with unique IDs. I am looking for a way to maintain the functionality of labels and input fields while still being able to clone them. While I prefer a solution using vanilla JavaScript, I am open to any suggestions that will help overcome this issue. Thank you for your assistance.

Answer №1

If you need to ensure unique IDs and labels for each element, one approach is to add an incrementing number to each one:

Consider this example:

const container = document.querySelector('.clone-container')
container.querySelectorAll('.clone-me').forEach((item, index) => {
  // Clone the element
  let cloned = item.cloneNode(true)
  
  // Add an incrementing number to label and input to ensure uniqueness
  cloned.querySelector('label').setAttribute('for', `anything${index}`)
  cloned.querySelector('input').setAttribute('id', `anything${index}`)
  
  // Append the cloned element
  container.append(cloned)
})
<div class="clone-container">
  <div class="clone-me">
    <label for="option1">Option 1</label>
    <input type="radio" id="option1" name="options">
  </div>
  <div class="clone-me">
    <label for="option2">Option 2</label>
    <input type="radio" id="option2" name="options">
  </div>
</div>

You can eliminate the need for inputs by using the attribute contentedible="true" on the element. Additionally, for radio buttons, you can forgo the use of inputs by implementing "onClick" event listeners that apply a selected class.
