How do you add options to a select box in JavaScript?


Recommended Posts

Add options to a select box in JavaScript:

1) Using the Option constructor and add() method:

First, use the Option constructor to create a new option with the specified option text and value:

let newOption = new Option('Option Text','Option Value'); 
Then, call the add() method of the HTMLSelectElement element:

const select = document.querySelector('select');  
2) Using the DOM methods

First, construct a new option using DOM methods:

// create option using DOM 
const newOption = document.createElement('option'); 
const optionText = document.createTextNode('Option Text'); 
// set option text 
// and option value 
newOption.setAttribute('value','Option Value'); 
Second, add the new option to the select element using the appendChild() method:

const select = document.querySelector('select');
