That whole if section is executed only on IE. That whole if section is executed only on IE. I found out that IE10 and IE Edge do things a bit differently.. go figure. The type attribute must return the value it was initialized to. id.substr(id.length - 1); //get the last character id.substr(2); //get the characters from the 3rd character on id.substr(2, 1); //get the 3rd character id.substr(2, 2); //get the 3rd and 4th The resulting value includes the year, month, and day, but not the time.

An additional optimization technique to lazify or delay the calculation of a property value and cache it for later access are smart (or memoized) getters. To get current date/time in javascript: var date = new Date(); If you need milliseconds for easy server-side interpretation use. That whole if section is executed only on IE.

Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more. The reason that this doesn't work is because the variable doesn't change with the textbox.
