copied!<p>This might be a little cleaner version, also note that you should always use a radix when using parseInt.</p> <pre><code>window.addEvent('domready', function() { // Create a Date object set to midnight on today's date var today = new Date((new Date()).setHours(0, 0, 0, 0)), input = $('datum').getValue(), dateArray = input.split('/'), // Always specify a radix with parseInt(), setting the radix to 10 ensures that // the number is interpreted as a decimal. It is particularly important with // dates, if the user had entered '09' for the month and you don't use a // radix '09' is interpreted as an octal number and parseInt would return 0, not 9! userMonth = parseInt(dateArray[1], 10) - 1, // Create a Date object set to midnight on the day the user specified userDate = new Date(dateArray[2], userMonth, dateArray[0], 0, 0, 0, 0); // Convert date objects to milliseconds and compare if(userDate.getTime() > today.getTime()) { alert(today+'\n'+userDate); } }); </code></pre> <p>Checkout the MDC <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/parseInt" rel="nofollow noreferrer">parseInt</a> page for more information about the radix.</p> <p><a href="http://www.jslint.com/" rel="nofollow noreferrer">JSLint</a> is a great tool for catching things like a missing radix and many other things that can cause obscure and hard to debug errors. It forces you to use better coding standards so you avoid future headaches. I use it on every JavaScript project I code.</p>
