"Setting an index to a button's ID using Jquery: A step-by-step guide

My goal is to assign incrementing index values to button IDs in a loop. For example, if the first button has an ID of 'unique', the second button should have an ID of 'unique0', and the third button should have an ID of 'unique1', and so on. I want to ensure that each button has a unique ID within the loop. Can anyone provide guidance on how to achieve this?

Note: I need button IDs in the format 'unique0', 'unique1', 'unique2', etc.

Answer №1

Iterate through each button element to update their IDs.

$(".btn").each(function(index) {
    this.id = 'newID' + index;
    this.innerText += index;
});
