In jQuery, you can increase the name of the form element by 1 in the following way:

  1. Get the name of the current form element:
var currentName = $('input').attr('name'); 
Copy after login

This Will return the name of the current form element input box. For example: If the current element name is "input1", the value of currentName will be "input1".

  1. Convert the current name to a number and increment it by 1:
var newName = parseInt(currentName.match(/d+/g)) + 1; 
Copy after login

This will extract the numeric part of the current name and convert it to a numeric type. Then, add 1 to that number to get the new name. For example: If the current name is "input1", the value of newName will be 2.

  1. Apply new name to element:
$('input').attr('name', 'input' + newName);
Copy after login

This will replace the name of the current element with the new name. For example: If the new name is 2, the element name will become "input2".

The complete code is as follows:

var currentName = $('input').attr('name');
var newName = parseInt(currentName.match(/d+/g)) + 1; 
$('input').attr('name', 'input' + newName);
Copy after login

This method can be used in scenarios such as creating form elements, dynamically adding form elements, or renaming form elements.
