視差效果是一個跳躍laggy

-1

好的。我試圖製作一個適用於所有瀏覽器的視差網站。我已經在所有的瀏覽器上取得了效果，但在某些瀏覽器中卻很慢並且很jump jump。有什麼辦法可以讓它流暢嗎？視差效果是一個跳躍laggy

這裏是我的代碼

function Draw(){ 
 
    requestAnimationFrame(Draw); 
 
    scrollEvent(); 
 
} 
 

 
Draw(); 
 

 
function scrollEvent(){ 
 
    var height = $(window).height(); 
 

 
    if($(document).scrollTop() <= height){ 
 
     $('#home').css('transform', 'translate3d(0, ' + ($(document).scrollTop() + 'px, 0)')); 
 
     $('#about').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - height + 'px, 0)')); 
 
    }else if($(document).scrollTop() <= 2*height){ 
 
     $('#about').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -height + 'px, 0)')); 
 
     $('#gallery').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 2*height + 'px, 0)')); 
 
    }else if($(document).scrollTop() <= 3*height){ 
 
     $('#gallery').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -2*height + 'px, 0)')); 
 
     $('#blog').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 3*height + 'px, 0)')); 
 
    }else if($(document).scrollTop() <= 4*height){ 
 
     $('#blog').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -3*height+ 'px, 0)')); 
 
     $('#contact').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 4*height + 'px, 0)')); 
 
    } 
 
}

嘗試transition: transform 200ms ease;到正在轉化的元素。這應該會增加您在js中應用的轉換。

沒有。這使得它甚至更糟...... – Kinggeov

好的。你是否以另一種方式解決了問題？ – Davey

我仍在嘗試... – Kinggeov
