出于某种原因,firefox 似乎忽略了我的 scrollTo 功能,即使它适用于 chrome 和 safari。
这是一个示例链接:http ://blog.rainbird.me/post/2358248459/blowholes-are-awesome
Chrome 和 Safari 会自动滚动到图片顶部(偏移 20 像素)
它在Firefox中不起作用。我很困惑!
代码:
$(document).ready(function() {
$(".photoShell img").lazyload({
placeholder: "http://william.rainbird.me/boston-polaroid/white.gif",
threshold: 200
});
window.viewport =
{
height: function() {
return $(window).height();
},
width: function() {
return $(window).width();
},
scrollTop: function() {
return $(window).scrollTop();
},
scrollLeft: function() {
return $(window).scrollLeft();
}
};
$(".photoShell img").hide();
$(".photoShell .caption").hide();
$(".photoShell img").load(function() {
var maxWidth = viewport.width() - 40; // Max width for the image
if(maxWidth > 960){
maxWidth = 960;
}
var maxHeight = viewport.height() - 50; // Max height for the image
var ratio = 0; // Used for aspect ratio
var width = $(this).width(); // Current image width
var height = $(this).height(); // Current image height
// Check if the current width is larger than the max
if(width > maxWidth){
ratio = maxWidth / width; // get ratio for scaling image
$(this).css("width", maxWidth); // Set new width
$(this).css("height", height * ratio); // Scale height based on ratio
height = height * ratio; // Reset height to match scaled image
width = width * ratio; // Reset width to match scaled image
}
// Check if current height is larger than max
if(height > maxHeight){
ratio = maxHeight / height; // get ratio for scaling image
$(this).css("height", maxHeight); // Set new height
$(this).css("width", width * ratio); // Scale width based on ratio
width = width * ratio; // Reset width to match scaled image
}
$(this).parents('div.photoShell').css("width", $(this).width() + 22);
$(this).parents('div.photoShell').addClass('loaded');
$(this).next(".caption").show();
var scrollNum = $(this).parents('div.photoShell').offset().top;
$.scrollTo(scrollNum - 20, {duration: 700, axis:"y"});
$(this).fadeIn("slow");
}).each(function() {
// trigger the load event in case the image has been cached by the browser
if(this.complete) $(this).trigger('load');
});
