在URL上使用锚点平滑滚动

Question

I'm trying to use Smooth Scroll on my site, but I need the anchor id on URL, to give the funcion of browser Back Button. The problem is: I need the #anchor to show up before 400 ms, but I don't know how can I call that variable in my script.

$(document).ready(function(){
  $('a[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) {
        var targetOffset = $target.offset().left;
        $('html,body')
        .animate({scrollLeft: targetOffset}, 400);
 var timer = setTimeout(function() {  
        window.location.href = '#[anchor]';
   }, 400);
       return false;
      }
    }
  });
});

The window.location.href = '#[anchor]'; change the url but not with the anchor name. How can I change that?

Answer 1

The anchor is stored in the hash variable, see the example and check the comments:

if (target.length) {

    var _this = this; // first save the reference to 'this'

    var targetOffset = $target.offset().left;
    $('html,body').animate({scrollLeft: targetOffset}, 400);
    var timer = setTimeout(function() {  
        window.location.href = _this.hash; // '_this.hash' contains the anchor
    }, 400);
    return false;

You can also use window.location.hash like this:

window.location.hash = _this.hash;
