JQuery Scroll to Offset from top of browser?
提问by Jezthomp
I have the following scroll script, which scrolls round the page fine, works exactly how i want it too.
我有以下滚动脚本，它可以很好地滚动页面，也完全符合我的要求。
$(function(){
$('a[href*=#]').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
&& location.hostname == this.hostname) {
var $target = $(this.hash);
$target = $target.length && $target || $('[name=' + this.hash.slice(1) +']');
if ($target.length) {
var targetOffset = $target.offset().top;
$('html,body').animate({scrollTop: targetOffset}, 1000);
return false;
}
}
});
});
However, i need it to ignore the top say 200px as i have a fixed header at the top of the page that the content scrolls behind.
但是，我需要它忽略顶部说 200px，因为我在页面顶部有一个固定的标题，内容滚动到后面。
Meaning that when i scroll to top it scrolls the content to behind the fixed header so i cannot see it, so i need it to scroll to just below the header.. so to treat the bottom of the header as the top of the browser i suppose....
这意味着当我滚动到顶部时，它会将内容滚动到固定标题的后面，所以我看不到它，所以我需要它滚动到标题的正下方..所以将标题的底部视为浏览器的顶部我认为....
Can this be done as it would be very handy?
可以这样做吗，因为它会非常方便吗？
Many thanks for any help

Would something like this work?
这样的东西会起作用吗？
var targetOffset = $target.offset().top - 200;
Or grab the height of the header element for the extra offset.
或者获取标题元素的高度以获得额外的偏移量。
var targetOffset = $target.offset().top - $("element").outerHeight(true);

You could use something like this if condition on ur code to do that
如果你的代码有条件，你可以使用这样的东西来做到这一点
//check if the absolute position is below header
if ($('#IdOfTheScrollElement').position().top >= 200 ){
//scroll
}
else {
//do nothing
}

The Code is fine, you just need to remove the height of your fixed header here, for example if it's 200px. it will work perfectly.
代码很好，您只需要在此处删除固定标题的高度，例如如果它是 200px。它会完美地工作。
$('html,body').animate({scrollTop: (targetOffset().top)-200}, 1000);
You can also check this when a button is clicked
您也可以在单击按钮时进行检查
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
// Check height of the header and padding
var header_height = $('.header').outerHeight();
Remove it from your offset
从您的偏移量中删除它
$('html,body').animate({scrollTop: (targetOffset().top) - header_height }, 1000);
