Salesforce: A better way to work with jQuery selectors and Visualforce Component Ids

by

I get very sad when discussing this particular topic. There are a variety of ways of get Visualforce component Ids and using them in JavaScript but all of them keep me awake at night. Srsly. A commenter on one of my posts got me thinking about how we can do this better and I’ve come up with a way that I think is great. Hopefully you’ll agree. This post means that my older posts here and here are now retired in favour of this method. If the world was on the brink of nuclear war with no clear path to peace what could you count on to save the day? Regular Expressions of course.

Now we’re going to jazz it all up with our spiffy jQuery gallery carousel. Let’s have another look at where we want to be at the end of this all,

There can(and probably will) be some frustration while you bend a library and make it fit within the Salesforce framework, although Ron Hess has some pretty sweet examples for you to pore over.

One simple frustration I’ve come across is that of retrieving elements by Id. Salesforce has an intelligent scheme in place which ensures that HTML elements don’t have duplicate Ids and therefore conform to W3C standards.
