javascript - Using Jquery to move a div based on .scroll depending on window.scrollY -


what trying accomplish have div appear left side after user has scroll past number of pixels. when passes point moves right , disappears again. if user scrolls have div reverse movement.

the issue running when div moves right side extends view unlike when on left side. have tried changing left value right value nothing have tried works.

here code have far jquery: 

window.addeventlistener('scroll', function() {   if (window.scrolly <= 50) {     $('#leftinfo').animate({left: '-150%'});   }   else if (window.scrolly >= 50 && window.scrolly <= 200){     $('#leftinfo').animate({left: '25%'}, 'swing');   }    else if (window.scrolly >= 200) {     $('#leftinfo').animate({left: '100%'}, 'swing');   } });

i have link js bin. http://jsbin.com/hadabe/7/edit?css,js,output

first of all, jquery animations on same object queued , executed in first come first serve order. need stop them first calling .stop() clear animation queue new animation execute right away.

secondly, prevent window extending scrollable area, need instruct html body hide elements overflow boundries, on x-axis.

window.addeventlistener('scroll', function() {    if (window.scrolly <= 50) {      console.log("phase i");      $('#leftinfo').stop().animate({        left: '-150%'      });    } else if (window.scrolly >= 50 && window.scrolly <= 200) {      console.log("phase ii");      $('#leftinfo').stop().animate({        left: '25%'      }, 'swing');    } else if (window.scrolly >= 200) {      console.log("phase iii");      $('#leftinfo').stop().animate({        left: '100%'      }, 'swing');    }  });
body {    margin: 0;    height: 75rem;    width: auto;    float: right;    display: inline-block;    overflow-x: hidden;  }  .frontintro {    border: 1px solid black;    background-color: #ffffff;    padding: 1rem;    display: inline-block;    color: #000000;    border-radius: 15px;  }  #leftinfo {    position: absolute;    top: 15rem;    width: 65%;    z-index: 100;    left: -150%;  }  #leftinfo p {    font-size: 2rem;    text-align: center;  }  #rightinfo {    float: right;    position: relative;    margin: 5rem;    width: 35%;  }  #rightinfo p {    font-size: 1.5rem;    text-align: center;  }  #first {    background: #c6bea6;    background-size: cover;    color: white;    height: 52rem;    margin: 0 auto;    padding: 0;    position: relative;    z-index: 300;  }  #second {    background: #9e9e9e;    background-size: cover;    color: white;    height: 800px;    margin: 0 auto;    overflow: hidden;    padding: 0;    position: relative;    z-index: 200;  }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
