如何在引導scrollspy和Affix中為href錨定偏移距離
[英]How to make an offset distance for href anchor in bootstrap scrollspy and Affix
問題描述
使用href錨點時，navmenu覆蓋的div內容。 開始的div也需要在錨點點擊時顯示。 單擊錨點時，是否可以選擇與菜單保持距離？

您需要使用：
scrollTop: target.offset().top - 125
坦率地說- 125是反復試驗。 應從navbar高度計算得出。
片段
$(document).ready(function() { $('a[href*=#]:not([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) { $('html,body').animate({ scrollTop: target.offset().top - 125 }, 1000); return false; } } }); });
body { position: relative; } .affix { width: 100%; } #section1 { background-color: #1E88E5; } #section2 { background-color: #673ab7; } #section3 { background-color: #ff9800; } #section41 { background-color: #00bcd4; } #section42 { background-color: #009688; } .customdiv { height: 500px; color: #fff; } .navbar-default { margin-bottom: 0; background-color: transparent; border: none; } .navbar-default.affix { margin: auto; right: 0; left: 0; transition: all .6s ease-in-out; } .navbar-default.affix + .container-fluid { /* padding-top: 70px */ }

嘗試scrollTop: target.offset().top - 50並設置margin-top: 50px; 到body 。 參見示例。
$(document).ready(function() { $('a[href*=#]:not([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) { $('html,body').animate({ scrollTop: target.offset().top - 50 }, 1000); return false; } } }); });
body, html { position: relative; margin-top: 50px; } #section1 { background-color: #1E88E5; } #section2 { background-color: #673ab7; } #section3 { background-color: #ff9800; } #section41 { background-color: #00bcd4; } #section42 { background-color: #009688; } .customdiv { height: 500px; color: #fff; } .navbar-default { background-color: transparent; border: none; } .navbar-default.affix { margin: auto; right: 0; left: 0; transition: all .6s ease-in-out; }
