在滚动时禁用滚动

Question

我正在写一个代码，它激活了100％body.height的滚动。一切工作正常，但我试图禁用滚动，而动画最后，以防止进一步不需要的行为。 我使用这个代码

function animate(x) { 
    var start = new Date(); 
    var id = setInterval(function (e) { 

     var timepassed = new Date() - start; 
     var progress = timepassed/x.duration; 
     if (progress > 1) { 
      progress = 1; 
     } 
     var delta = x.delta(progress); 
     x.step(delta); 
     if (progress == 1) { 
      clearInterval(id); 

     } 

    }, x.delay); 


} 

function fak(e) { 
    e.preventDefault(); 
    return false; 
} 

function move(e) { 
    e.preventDefault(); 
    var wheel = e.wheelDelta; 
    wheel = (wheel == 120) ? "-1" : "1"; 
    var body_height = document.body.offsetHeight; 
    var scrollIt = body_height * wheel; 
    var page = window.pageYOffset; 
    animate({ 
     delay: 10, 
     duration: 700, 
     delta: function (p) { 
      return p; 
     }, 
     step: function (delta) { 
      window.scrollTo(0, page + (delta * scrollIt)); 
     } 
    }); 
    return false; 
} 
document.body.addEventListener("mousewheel", move, false); 
document.body.addEventListener("DOMMouseScroll", move, false); 

我试图分配功能FAK，在鼠标滚轮，mousescroll区间，然后原来的分配新建分配FY在年底使用

function animate(x) { 
    var start = new Date(); 
    var id = setInterval(function (e) { 
    document.body.addEventListener("mousewheel", fak, false); 
    document.body.addEventListener("DOMMouseScroll", fak, false); 
     var timepassed = new Date() - start; 
     var progress = timepassed/x.duration; 
     if (progress > 1) { 
      progress = 1; 
     } 
     var delta = x.delta(progress); 
     x.step(delta); 
     if (progress == 1) { 
      clearInterval(id); 
    document.body.addEventListener("mousewheel", move, false); 
    document.body.addEventListener("DOMMouseScroll", move, false); 

     } 

    }, x.delay); 


} 

但没有工作或者恢复到它们。现场演示：http://jsfiddle.net/Trolstover/o2pvo2t8/我忽略了什么？

我改变了一下你的代码。

只是设置一个标志，“运行”，而滚动（在动画的开始（）），并在年底将其清除。 并仅在没有滚动出现时执行mov。

希望它帮助。

var running; 

function animate(x) { 
    running = 1; 
    var start = new Date(); 
    var id = setInterval(function (e) { 

     var timepassed = new Date() - start; 
     var progress = timepassed/x.duration; 
     if (progress > 1) { 
      progress = 1; 
     } 
     var delta = x.delta(progress); 
     x.step(delta); 
     if (progress == 1) { 
      clearInterval(id); 
      running = 0; 
     } 

    }, x.delay); 


} 

function fak(e) { 
    e.preventDefault(); 
    return false; 
} 

function move(e) { 
    e.preventDefault(); 
    if (running==1) return; 
    var wheel = e.wheelDelta; 
    console.log(wheel); 
    wheel = (wheel == 120) ? "-1" : "1"; 
    var body_height = document.body.offsetHeight; 
    var scrollIt = body_height * wheel; 
    var page = window.pageYOffset; 
    animate({ 
     delay: 10, 
     duration: 700, 
     delta: function (p) { 
      return p; 
     }, 
     step: function (delta) { 
      window.scrollTo(0, page + (delta * scrollIt)); 
     } 
    }); 
    return false; 
} 
document.body.addEventListener("mousewheel", move, false); 
document.body.addEventListener("DOMMouseScroll", move, false);
