I use this script to check if an anchor is within the URL. If found the showscroll function get called.
Only thing isn’t working is the jump to the called anchor.
I’m new to JS – what is wrong with the function?

In the HTML page:

   <script type="text/javascript">
    <!--
    function checkurl(){
    if (window.location.href.match(/\#more/))
    {
    showscroll('more');
    }
    if (window.location.href.match(/\#tab2/))
    {
    showscroll('tab2');
    }

    }
    //-->
    </script>

    </head>                   

    <body onload="checkurl()">

.JS 

function showscroll(id){
    if (document.getElementById) {
    var divid = document.getElementById(id);
    divid.style.display = divid.style.display='block';
    // NOT WORKING:
 window.location.href = "#"+id;
//
    return false;
} }

Edit: I can’t use “scroll into view”.

    Instead of

    window.location.href.match(/\#more/)

    you can just do

    window.location.hash == '#more'

    and instead of assigning to the fragment, you can use the scrollIntoView method as described at https://developer.mozilla.org/en/DOM/element.scrollIntoView

    Summary

    The scrollIntoView() method scrolls the element into view.

    Syntax

    element.scrollIntoView(alignWithTop);

    alignWithTop Optional

    If true, the scrolled element is aligned with the top of the scroll area. If false, it is aligned with the bottom.
    Note: By default, the element is scrolled to align with the top of the scroll area.
