Is referencing a selector faster in jquery than actually calling the selector? if so, how much does it make a difference?

Question

$(preview-button).click(...)
$(preview-button).slide(...)
$(preview-button).whatever(...)

Is it a better practice to do this:

var p         


        

Answer 1

Yes. You could also chain it:

$(preview-button)
    .click(...)
    .slide(...)
    .whatever(...);
