如何使用jQuery上下滚动页面至锚点? [英] How to scroll up or down the page to an anchor using jQuery?

问题描述

我正在寻找一种方法，当您单击指向页面上方或下方的本地锚点的链接时，添加一种幻灯片效果.

I'm looking for a way to include a slide effect for when you click a link to a local anchor either up or down the page.

我想在您的链接中添加以下内容:

I'd like something where you have a link like so:

<a href="#nameofdivetc">link text, img etc.</a>

也许添加了一个类，所以您知道希望此链接成为滑动链接:

perhaps with a class added so you know you want this link to be a sliding link:

<a href="#nameofdivetc" class="sliding-link">link text, img etc.</a>

然后，如果单击此链接，页面将向上或向下滑动到所需位置(可以是div，标题，页面顶部等).

Then if this link is clicked, the page slides up or down to the required place (could be a div, heading, top of page etc).

这是我以前的经历:

    $(document).ready(function(){
    $(".scroll").click(function(event){
        //prevent the default action for the click event
        event.preventDefault();

        //get the full url - like mysitecom/index.htm#home
        var full_url = this.href;

        //split the url by # and get the anchor target name - home in mysitecom/index.htm#home
        var parts = full_url.split("#");
        var trgt = parts[1];

        //get the top offset of the target anchor
        var target_offset = $("#"+trgt).offset();
        var target_top = target_offset.top;

        //goto that anchor by setting the body scroll top to anchor top
        $('html, body').animate({scrollTop:target_top}, 1500, 'easeInSine');
    });
});

推荐答案

说明

您可以使用jQuery.offset()和jQuery.animate()进行此操作.

Description

You can do this using jQuery.offset() and jQuery.animate().

查看 jsFiddle演示.

function scrollToAnchor(aid){
    var aTag = $("a[name='"+ aid +"']");
    $('html,body').animate({scrollTop: aTag.offset().top},'slow');
}

scrollToAnchor('id3');
