jQuery in Custom Input Components

I'm trying to write my own custom input component that updates values based on button clicks. The component idea is similar to the enhanced jQuery input components created by Joel Dietz, although far less universal in application. An example of Joel's components can be found below.

"enhancedText.component"

"EnhancedTextController.cls"

One trick to making the component inputs work is to factor in the quirky DOM ID's generated by Salesforce. This is addressed in the following blog post from Wes Nolte.

"VisualForce Element Ids in jQuery selectors"
The Silver Lining

To clarify Wes's post, the function is defined as follows:

function esc(myid) {
    return '#' + myid.replace(/(:|\.)/g,'\\\\$1');
}

Also, the esc function cannot be called with a literal! The String must be stored in a var first, and the var should then be passed to the esc function.

Whew! I'm not done with my custom input component yet, but I definitely see bright rays of hope.
