Custom WP LayerSlider Fix: hide first slide for the first seven day of a month

hi, i have a wp layerslider in home (#layersliders_1) and i wuold like to hide the first slide if we are in the first seven day of month. From LayerSliders WP backend for each slider we have an "event callback" section. I have to insert the code into "sliderWillLoad" event ("Fires before parsing user data and rendering the UI.") to get my goal. So i wuold like to use this js code: var d = new Date();var d = new Date(); var n = [login to view URL](); if (n <= 7) { [login to view URL]('yessa, siamo nei primi sette giorni: '); } else { [login to view URL]('nooo, non siamo nei primi sette giorni: '); } But i dont't understand how chenge/edit the layerSlider (jQUery) Object. This the link to documentation: [login to view URL] It's a simple task i think but i'm blocked. i try to edit [login to view URL] but it's not works. Documentation suggest me to bind the event to the target elment but i don't understand the reasons becouse if i write [login to view URL](event) i get the current slider object. p.s i can write the rest of code myself but i need some info on how manipulate correctly the layerslider object. I would also be willing to pay for this naturally:)
