jQuery statement chaining

- [Joe] I want to point out one of jQuery's…more interesting features and that is its ability…to chain multiple functions together.…This is called statement chaining.…It basically allows you to perform several operations…on a result set in just one line of code.…Up until now, you've seen a lot of code…that looks like this.…A jQuery selector statement followed by a function…call that operates on the result set that comes back.…However, I can chain multiple function calls together,…one after another to operate on the result set…as you see here.…

This is called a statement chain.…These functions will get executed in order,…starting on the left and going across to the right.…So the selector will execute,…then the results that will come back…and I can do multiple operations on those objects.…I can assign CSS, I can manipulate the content,…I can turn events on and off.…And the reason why this makes jQuery so powerful…is that it allows you to perform…multiple operations on one result set…without having to get that result set…
