Utilizing CSS or JavaScript to define the input type

Question

Utilizing CSS or JavaScript to define the input type

I currently have a group of checkboxes displayed on a webpage within a DIV labeled OPTIONS, shown below:

<div id="options">     
<input type="checkbox"..... > 
<input type="checkbox"..... >
<input type="checkbox"..... >
<input type="checkbox"..... >
<input type="checkbox"..... >
...
...
</div>

Considering that every input inside this specific DIV will always function as a checkbox, I am interested in finding out if there is a way to automatically assign them the checkbox functionality without having to manually specify type="checkbox" for each one using CSS or JavaScript.

Answer 1

Answer №1

It is recommended to set the input type in the HTML for better performance. By default, the input type is 'text', and changing it through JavaScript can be slower than setting it directly in the HTML.

If you still choose to do so, you can target the element, get its children, and then loop over them to change the type using the setAttribute method.

document.getElementById('options').children

will return a collection which can be converted into an array using the spread operator ... for easier manipulation.

[...document.getElementById('options').children].forEach(item => {
  item.setAttribute('type', 'checkbox')
})

<div id="options">
  <input>
  <input>
  <input>
  <input>
  <input>

</div>

A simple solution in JavaScript would be:

const allInputs = Array.from(document.querySelectorAll("input"));
allInputs.forEach(input => {
    input.setAttribute("type", "checkbox");
});

This code snippet takes the NodeList of <input> elements and converts it into an array, then changes the type attribute to "checkbox".

If you prefer using jQuery or ES6 syntax:

$("input").each(input => input.attr("type", "checkbox"));
