在滾動時禁用滾動

Question

我正在寫一個代碼，它激活了100％body.height的滾動。一切工作正常，但我試圖禁用滾動，而動畫最後，以防止進一步不需要的行爲。 我使用這個代碼

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); 

我試圖分配功能FAK，在鼠標滾輪，mousescroll區間，然後原來的分配新建分配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); 


} 

但沒有工作或者恢復到它們。現場演示：http://jsfiddle.net/Trolstover/o2pvo2t8/我忽略了什麼？

我改變了一下你的代碼。

只是設置一個標誌，「運行」，而滾動（在動畫的開始（）），並在年底將其清除。 並僅在沒有滾動出現時執行mov。

希望它幫助。

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);
