JavaScript
var child1 = document.getElementById('child1');
var child2 = document.getElementById('child2');
var child3 = document.getElementById('child3');
var child4 = document.getElementById('child4');
// 点击首页和考试动态的跳转方式是通过window.scrollTo()
child1.onclick = function(){
window.scrollTo({
top: 0,
behavior: "smooth"
});
}
child4.onclick = function(){
window.scrollTo({
top: 1655,
behavior: "smooth"
});
}
// 点击学习中心和考试中心是通过element.scrollIntoView()
child2.onclick = function(){
document.querySelector('.studyCenter').scrollIntoView({ behavior: 'smooth', block: 'start' });
}
child3.onclick = function(){
document.querySelector('.examinationCentre').scrollIntoView({ behavior: 'smooth', block: 'start' });
}

两种跳转方式的详情参考MDN文档：window.scrollTo()和element.scrollIntoView()
element.scrollIntoView()是相对于视口跳转，而window.scrollTo()是根据自定义的位置跳转，从而更加灵活。
