Question

I am using JavaScript with jQuery. I have the following

var $ticket = $nxt.parent().prev().children('.ticket');

and $ticket.text() is integer 1.

I want to increment it by 1 when when I click as;

$('.next').click(function()

How can I do this??

Answer 1

A fancy solution would be

$.fn.extend({
  increment: function () {
    return this.text( function (i, currentText) {
      return parseInt(currentText, 10) + 1;
    });
  }
});

In your case use as:

$nxt.parent().prev().children('.ticket').increment();
