jQuery move to anchor location on page load

问题:

I have a simple page setup such as:

<div id="aboutUs">
  About us content...
</div>
<div id="header">
  Header content...
</div>

When the page loads, I need the page to automatically scroll down (no animation needed) to #header, so the user cannot see the About Us div unless they scroll up.

#aboutUs has a fixed height, so there isn't any need for any variables to determine the height or anything... if that's even needed.

I came across this other question and tried to modify some of the answers for my situation, but nothing seemed to work.

Any help would be appreciated.

回答1:

Description

You can do this using jQuery's .scrollTop() and .offset() method

Check out my sample and this jsFiddle Demonstration

Sample

$(function() {
    $(document).scrollTop( $("#header").offset().top );  
});

• jQuery.offset()

Did you tried JQuery's scrollTo method? http://demos.flesler.com/jquery/scrollTo/

Or you can extend JQuery and add your custom mentod:

jQuery.fn.extend({
 scrollToMe: function () {
   var x = jQuery(this).offset().top - 100;
   jQuery('html,body').animate({scrollTop: x}, 400);
}});

Then you can call this method like:

$("#header").scrollToMe();

回答3:

Put this right before the closing Body tag at the bottom of the page.

<script>
    if (location.hash) {
        location.href = location.hash;
    }
</script>

jQuery is actually not required.
