It will copy the native functionality, and disable itself in browsers that already support the attribute.

This file will require a reasonably new version of jQuery to run correctly (and yes, it works in no-conflict mode).

jQuery.placeholder.1.0.1.min

And while I love PHP, it just doesn’t come with some of the free things I take for granted in .Net

Today, while working on a pretty simple plugin, I wanted to add this functionality, and I didn’t want to waste a bunch of time. I was given a link to this great script: http://www.warkensoft.com/2009/12/paginated-navigation-bar/

It took me about a minute to implement the functionality. I then spent another 5 minutes doing CSS and that was it. Done. I’m not usually one for link sharing, but this made my life much easier. Hopefully it can make yours easier too.

The solution is pure PHP, no javascript required. Some day, I may try to expand upon this to include javascripty goodness, because that’s pretty much the only thing that could make it better

//tell javascript to run a function in 1 second
setTimeout ("myFunction()", 1000 );

function myFunction(){
//do stuff

//once the function is finished, queue this function up to run again in 1 second
setTimeout ( "myFunction()", 1000 );
}

  1. go to google maps, type the address, and click search
  2. once you’ve found it, go to your address bar and clear what’s in it
  3. paste: javascript:void(prompt('',gApplication.getMap().getCenter())); into the address bar
  4. use the coordinates for whatever you wish!

Why, yes it would. Try:


Event.observe(window, 'load', function(){
     try {
          $('eventName').focus();
     } 

     catch (e) {}
});

after your </form> tag. This requires the prototype javascript library
