jquery - $(window).scroll() Loop, due to no variable -


i have bit of problem; have code:

  $(window).scroll(function(){     if ($(document).scrolltop() >= $('.services-container').offset().top-80) {       alert("test");     }   });

now works ok, except need run if statement once, tried variables cannot them not re-set previous state due window scroll loop... help?

you can try flag:

var flag = true;  $(window).scroll(function() {     if ($(document).scrolltop() >= $('.services-container').offset().top-80 && flag) {        alert("test");        flag = false;     } });
