Unobtrusive JavaScript password strength checker

I’ve added a couple of new functions to Performer – my easy to use JavaScript library. The two new functions allow you to check the strength of a password as it’s typed into a text box, and also check if a password and its confirmation match. Both update a notification element with a suitable message.

But that’s not all. Some of the older functions, such as the AJAX loader and tabbing functions, have got a little love as well. They now add extra classes to the elements they affect so you can style them easily. This stuff isn’t documented yet, but in a nutshell:

  • When loading some data from a remote page using the Loader function the element which is being updated will have the class ‘loaderloading’ while the loading is happening. Phew, a few too many ‘loader’s there.
  • When using the Tabber function to switch the visibility between different elements in a tag group, the link to the selected tab will have an additional class of ‘tabbercurrent’.
  • UPDATE: the Toggler function adds the class ‘toggleropen’ when the toggled element is being shown. That means you can easily do ‘open’ and ‘close’ CSS styles.

I’ve got lots more ideas for Performer, but time is short at the moment. However this little library – and the fantastic prototype library it’s built on – continue to make my life better.
