我正在为客户制作一个侧滚动博客文章页面。经过多次尝试和错误后，我最终使用 JQuery 使网站在较大时向右滚动，或者在移动时向上或向下滚动。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 40,000 像素。这是代码。
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-alpha1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-mousewheel/3.1.13/jquery.mousewheel.js"></script>
<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) {
// IE9, Chrome, Safari, Opera
window.addEventListener("mousewheel", scrollHorizontally, false);
// Firefox
window.addEventListener("DOMMouseScroll", scrollHorizontally, false);
} else {
// IE 6/7/8
window.attachEvent("onmousewheel", scrollHorizontally);
}
})();//function scrollHorizontally ends
} else {
}//else ends
});//onload ends
$(window).resize(function(){
var windowH = $(window).height();
var windowW = $(window).width();
if(windowW >= windowH) { //horizontal
var allImgWidth = 0;
$('article img').each(function(){
allImgWidth += $(this).width() + 11 ;
});
$('html, body').width(allImgWidth);
$('article img').height(windowH - 150);
$('article img').css('width','auto');//dynamically resizes pics
$('article img').css('margin-left', '9px');
} else { //vertical
$('html, body').width(windowW);
$('article img').width(windowW);
$('article img').css('height','auto');
$('article img').css('margin-top', '10px');
}
if(windowH >= windowW) {
$(window).on('mousewheel DOMMouseScroll', function(event){
if (event.originalEvent.wheelDelta > 0 || event.originalEvent.detail < 0) {
// scroll up
} else {
// scroll down
}
});
} else {
$(window).off('mousewheel DOMMouseScroll');
(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) {
// IE9, Chrome, Safari, Opera
window.addEventListener("mousewheel", scrollHorizontally, false);
// Firefox
window.addEventListener("DOMMouseScroll", scrollHorizontally, false);
} else {
// IE 6/7/8
window.attachEvent("onmousewheel", scrollHorizontally);
}
})();//function scrollHorizontally ends
}
});//window resize ends
})(jQuery);//full function ends
</script>
然后是页面本身的正文...

调整页面大小后，效果很好。 onload 对于小屏幕来说很好。只有在页面最初加载时的大屏幕中才会有这么大。想法？
最佳答案
您将使用以下代码将所有图像宽度添加在一起:
$('article img').each(function(){
allImgWidth += $(this).width() + 11 ;
});
然后将 html/body 宽度设置为该数字。
因此，如果页面宽度为 40,000px，则 allImgWidth 就等于该宽度。检查以确保页面上没有其他图像包含在 $('article img') 选择器中。
