jQuery scroll to ID from different page

I was trying to use jQuery's page scroll inside some pages and could successfully make a smooth page scroll. The only problem I have now is when attempting to do that from different page. What I mean by that is if I click on a link in a page, it should load the new page and then scroll to the specific div element.

Here is the code I used to scrolling inside the page:

var jump=function(e)
{
       //prevent the "normal" behaviour which would be a "hard" jump
       e.preventDefault();
   //Get the target
   var target = $(this).attr("href");
   //perform animated scrolling
   $('html,body').animate(
   {
           //get top-position of target-element and set it as scroll target
           scrollTop: $(target).offset().top
   //scrolldelay: 2 seconds
   },2000,function()
   {
           //attach the hash (#jumptarget) to the pageurl
           location.hash = target;
   });

}

$(document).ready(function()
{
       $('a[href*=#]').bind("click", jump);
       return false;
});

I hope the idea is clear.

Thanks

Very important Note: This code I posted above works great inside the same page, but what I'm after is to click a link from one page and go to another one and then scroll to the target. I hope it is clear now. Thanks

You basically need to do this:

  • include the target hash into the link pointing to the other page (href="other_page.html#section")
  • in your ready handler clear the hard jump scroll normally dictated by the hash and as soon as possible scroll the page back to the top and call jump() - you'll need to do this asynchronously
  • in jump() if no event is given, make location.hash the target
  • also this technique might not catch the jump in time, so you'll better hide the html,body right away and show it back once you scrolled it back to zero

This is your code with the above added:

var jump=function(e)
{
   if (e){
       e.preventDefault();
       var target = $(this).attr("href");
   }else{
       var target = location.hash;
   }

   $('html,body').animate(
   {
       scrollTop: $(target).offset().top
   },2000,function()
   {
       location.hash = target;
   });

}

$('html, body').hide();

$(document).ready(function()
{
    $('a[href^=#]').bind("click", jump);

    if (location.hash){
        setTimeout(function(){
            $('html, body').scrollTop(0).show();
            jump();
        }, 0);
    }else{
        $('html, body').show();
    }
});

Verified working in Chrome/Safari, Firefox and Opera. I don't know about IE though.
