jquery, add variable to element?

Question

I have a question regarding jQuery. I have a li that slides out, now I want to remember if it has slided out so I want to set a boolean variable slidedOut.

Is it possible to simply add it to the element? Or should I add a hidden div or something to to element?

Answer 1

You can use .data() for this.

Something like

$("#yourli").data("slidedOut", false);
