Obtaining the date a web page was last modified

If you wish to know the date a web page was last modified, when you are visiting the page, you can replace the URL of the page in the address bar with javascript:alert(document.lastModified) to see the date the page was last modified. Note: you can access the address bar by the keyboard shortcut Ctrl-L. If you are pasting javascript:alert(document.lastModified) into Internet Explorer's address bar, you may find that javascript: gets stripped off, so you will need to put it back in front of alert(document.lastModified) before hitting Enter.

One caveat is that this will only work for telling you when the content of the page was last modified for static web pages. Ones that include content dynamically, e.g., ads, etc. will show the time that the page was last modified as when that content for the page was last updated. I.e., the time may not be the time the author of the page wrote the information you've found on the page.

On a Microsoft Windows system, you will see a window similar to the following one open when you enter the javascript command in the address bar.

Last modified essage from webpage

Another technique to attempt to learn when a webpage was created or modified is to check the Wayback Machine to see when it archived the site.

IE 9 to 10 Upgrade Failure with Code 9C59 Error

Yesterday, while in the process of bringing all of the software on a laptop running Windows 7 Professional up-to-date, I tried upgrading Internet Explorer from version 9 to 10 as Windows Update listed it as one of the important updates pending installation on the system. But every time I tried updating Internet Explorer 9 to version 10 through Windows Update, I received a "Code 9C59" error message. I worked on the issue for all day yesterday before being finally being able to successfully complete the upgrade from IE 9 to 10 today after uninstalling packages from the C:\Widnows\servicing\packages directory via the pkgmgr /up command.

Google +1 button markup validation

At Google's +1 Button page, Google suggests adding start and end tags similar to the following at a point in a webpage where you want the plus 1 button to appear:


But if you use those tags on a page and check the page with the W3C Markup Validation Service, which checks the validity of HTML code, you will see errors reported such as the following:

White x in red circle Line 731, Column 11: element "G:PLUSONE" undefined


An alternative is to use another mechanism provided by Google to have the button appear. The alternative is to insert the following div start and end tags where you wish the button to appear.

<div class="g-plusone"></div>
