jquery - window resize function only one time for specific window size -

hi need if window less 768px alert , if window more 768px alert some, have script , else if(){} not work when window size more 768px p.s. need heppend when window less 768px or more 768px

var = 0; $(window).resize(function(){     if(width < 768 && == 0){         alert('less 768px');         i++;         alert(i);     }else if(width > 768){         alert('more 768px');         i==0;     } }); 

instead of i==0; should i=0; inside else if() because assigning value 0 i.

although don't know why using i complete code should :-

var = 0; $(window).resize(function(){     if(width < 768 && == 0){         alert('less 768px');         = 1;     }else if(width > 768 && == 1){         alert('more 768px');         = 0;     } });
