JavaScript

Question

I'm a novice to JavaScript but wanted to know how I could get a "Expire Date" box to automatically give me a date 1 year from the "Date Form Completed" box in a form I'm working on. I have no starting code, just the two boxes.

thanks

Anthony

Hi Anthony JavaScript contains a native Date object you can add months to it as follows... var endDate = document.getElementById('enddate').value; var date = new Date(endDate); date.setMonth(date.getMonth() + 2); // Yes it will calculate going over a year etc prevExpiryDate = date.getFullYear() + / + (date.getMonth() + 1) + / + // Months are 0 for January etc. date.getDate(); Note The format you are inputting the value to the Date object is important you will want to validate this first. When we are creating the expiry date the value will not be prepended with zeros 2012/12/09 it will be 2012/12/9 Or you can use a library as suggested Read more here http://stackoverflow.com/questions/12798535/javascript-display-expiry-date-upon-user-input-of-start-end-date Please accept and up vote if it helped you Kindest Regards Sibeesh http://sibeeshpassion.com/
