应用头部高度，体作为填充顶部的窗口大小调整

Question

我能够获取和window.resize应用header为padding top的height至body。问题是当我试图调整window全宽的resize功能不工作，我认为。

var headerHeight = $('header').innerHeight(); 
 
console.log(headerHeight); 
 
function carouselHeight(){ 
 
\t $('body').removeAttr('style'); 
 
\t $('body').css("padding-top", headerHeight); 
 
}; 
 
$(document).ready(function(e) { 
 
\t carouselHeight();  
 
}); 
 
$(window).resize(function(){ 
 
\t carouselHeight(); 
 
});

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

Answer 1

你必须这样执行它们：

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

$(document).ready(carouselHeight); 
$(window).resize(carouselHeight); 

Answer 2

对不起，我发现这个错误在我script。功能中没有提到标题高度。所以它没有得到正确的高度在调整大小

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);
