我正在为客户端制作一个侧面滚动博客帖子页面。经过多次试验和错误后，我最终使用JQuery使网站向右滚动（如果它是大的）或者如果它是移动的则向上和向下滚动。唯一的问题是当文档最初在非移动浏览器中加载时，它的宽度为40,000px。这是代码。

<script>
(function($){
var windowH = $(window).height();
var windowW = $(window).width();
$(window).on('load', function(){
if(windowW >= windowH) {//this is horizontal
var allImgWidth = 0;
$('article img').each(function(){
allImgWidth += $(this).width() + 10 ;//10 is padding
});
$('html, body').width(allImgWidth); //makes page width of all images and padding that I have set elsewhere
$('article img').height(windowH - 150);//this accounts for header height and margin height from top
// $('article img').css('margin-left', '10px');
} else {
$('article img').width(windowW);//if window width is not greater than window height, the images are the width of the original window
}
if(windowW >= windowH) {
(function() {
function scrollHorizontally(e) {
e = window.event || e;
var delta = Math.max(-1, Math.min(1, (e.wheelDelta || -e.detail)));
document.documentElement.scrollLeft -= (delta*80); // Multiplied by 80 (increases speed of scroll)
document.body.scrollLeft -= (delta*80); // Multiplied by 80
e.preventDefault();
}
if (window.addEventListener) {

然后页面的主体......

调整页面大小时，它可以正常工作。对于小屏幕，onload很好。只有在大屏幕上，当页面最初加载时它才是这么大。想法？
答案 0 :(得分：0)
您将所有图片宽度与此代码一起添加：
$('article img').each(function(){
allImgWidth += $(this).width() + 11 ;
});
然后将html / body宽度设置为该数字。
因此，如果页面的宽度是40,000px，那么allImgWidth等于。检查以确保页面上没有$('article img')选择器附带的其他图像。
