将标题高度应用于正文作为窗口大小调整时的填充顶部

Question

我能够获取并应用header的height，padding topbodywindow.resize。 问题是当我尝试将window调整为全宽时，我认为resize功能不起作用。

var headerHeight = $('header').innerHeight();
console.log(headerHeight);
function carouselHeight(){
	$('body').removeAttr('style');
	$('body').css("padding-top", headerHeight);
};
$(document).ready(function(e) {
	carouselHeight();    
});
$(window).resize(function(){
	carouselHeight();
});

body {
min-height: 2000px;
padding-top: 70px;
}

Answer 1

抱歉，我在script中发现了错误。函数中未提及标头高度。所以它在调整大小时没有得到正确的高度

function carouselHeight(){
var headerHeight = $('header').innerHeight();
$('body').removeAttr('style');
$('body').css("padding-top", headerHeight);
console.log(headerHeight);
console.log('hi');
};
$(document).ready(carouselHeight);
$(window).resize(carouselHeight);

Answer 2

你必须像这样执行它们：

var headerHeight = $('header').innerHeight();
console.log(headerHeight);
function carouselHeight(){
$('body').removeAttr('style');
$('body').css("padding-top", headerHeight);
};
$(document).ready(carouselHeight);
$(window).resize(carouselHeight);
