As I wrote in my recent post I simply use the PPK BrowserDetect object to find out the browser/OS of the client. Actually I’m pretty sure there’s a similar jQuery plugin based again on that code from Quirksmode.org, but however I decided to write a simple plugin for jQuery wrapping it into a closure and exporting it in the “$” object.
You can see full working example here.
You must add a link to jquery.client.js after the jquery.js file in your code:
<html> <body> <div id="os"></div> <div id="browser"></div> <script src="./jquery-1.3.2.js"></script> <script src="./jquery.client.js"></script> <script> $('#os').html("<b>" + $.client.os + "</b>"); $('#browser').html("<b>" + $.client.browser + "</b>"); </script> </body> </html>
Now there’s a $.client object containing two strings with OS and browser, they can be referenced with:
$.client.browser $.client.os
You can append this code after you jquery.js installation. And if you’re on Firefox you simply can test with the console object:
You can download the sample code from here.

It’s as simple as these lines of code:
$('#element_id').datepicker({
...
defaultDate : d,
...
});
The problem is when you attach this datepicker constructor to a div which is hidden, and than you make it visible like so: Read the rest of this entry »

The most simple way to describe the case is as if you have the ExternalInterface addCallback in the Flex application like that:
flex.mxml
ExternalInterface.addCallback("jsFunc", flexFunc);
public flexFunc() : void
{ ... }
and in the javascript code you’ve something like that: Read the rest of this entry »
