SoftScroll.



Description

~~~~~~~~~~~

 Provides progressive scrolling to anchor/element positions, including those in iframes or

 adjacent frames.



 Provides a direct replacement for the window.scrollTo function.



 Info: http://scripterlative.com?softscroll



 These instructions may be removed but not the above text.



 Please notify any suspected errors in this text or code, however minor.



THIS IS A SUPPORTED SCRIPT

~~~~~~~~~~~~~~~~~~~~~~~~~~

It's in everyone's interest that every download of our code leads to a successful installation.

To this end we undertake to provide a reasonable level of email-based support, to anyone 

experiencing difficulties directly associated with the installation and configuration of the

application.



Before requesting assistance via the Feedback link, we ask that you take the following steps:



1) Ensure that the instructions have been followed accurately.



2) Ensure that either:

   a) The browser's error console ( Ideally in FireFox ) does not show any related error messages.

   b) You notify us of any error messages that you cannot interpret.



3) Validate your document's markup at: http://validator.w3.org or any equivalent site.   

   

4) Provide a URL to a test document that demonstrates the problem.

 

Installation

~~~~~~~~~~~~

 Save this text/file as 'softscroll.js', and place it in a folder associated with your web pages.



 Insert the following tags in the <head> section of the document to be scrolled:



 <script type='text/javascript' src='softscroll.js'></script>



 (If softscroll.js resides in a different folder, include the relative path)



Configuration

~~~~~~~~~~~~~

 For normal operation no further configuration is required.



 To scroll the page to an initial anchor when it loads, insert the following code anywhere below

 the installation <script> tags, where "anchorName" is the name/ID of the target anchor:



 <script type='text/javascript'>



  SoftScroll.go("anchorName");



 </script>

  

 If you wish the target anchor to be displayed in the address bar once the scroll is completed,

 add this code below the script configuration:



  <script type='text/javascript'>



  SoftScroll.showHash();



  </script>



 Please note that in some circumstances this may cause a slight jump at the end of the scroll.



 Cross-Frame Scrolling

 ---------------------

 The script can scroll to anchors within an iframe in the same document, or another frame from the same <frameset>.

 The target document does not need to load a copy of the script.

 To configure a link to scroll within an iframe or adjacent frame, just set its 'target' attribute to

 the name of the target frame.  Do not include a 'URL' in the 'href' parameter. 

 The standard values: _top, _self, _parent & _blank are ignored.



 Examples:



 <a href='#iframeAnchor' target='if1'>Somewhere in the iframe 'if1' in this page</a>



 <a href='#otherFrameAnchor' target='main'>Somewhere in the adjacent frame called 'main'</a>



 ALL INVOLVED FRAMES MUST BE ON THE SAME DOMAIN.



 To load a new document in another frame and scroll to an anchor within it, use a conventional

 link with href=URL#anchor and appropriate 'target' attribute. The new document must load a copy

 of the script.



 Scrolling on Load

 -----------------

 If the script reads a # anchor in the URL of the document that loaded it, it will scroll to that

 anchor.



 Notes for correct operation

 ---------------------------

 If any involved links have an onclick handler, the handler must return false, i.e:



  <a href="#someAnchor" onclick="someFunc();return false">



 The ID of an element may be specified as an anchor, and NAME attributes may be specified for

 scrolling to form elements.



 If the document uses any other scripts that use the onload event, they should be loaded prior to

 SoftScroll and not initialised inside the <body> tag.



 Excluding Specific Links

 ------------------------

 To use conventional 'jump' scrolling for a specific link, add the word 'noSoftScroll' to its class attribute,

 I.E.



  <a class='noSoftScroll' ... >



  <a class='myLinkClass noSoftScroll' ... >





 Triggering with other element types

 -----------------------------------

 Example:



  <input type='button' value='Some target in this page' onclick='SoftScroll.go("myAnchor")'>



Replacement for scrollTo

~~~~~~~~~~~~~~~~~~~~~~~~

With the script installed, a progressive-scrolling alternative to the window.scrollTo function is available.



Call: SoftScroll.scrollTo(x, y);



GratuityWare

~~~~~~~~~~~~

This code is supplied on condition that all website owners/developers using it anywhere,

recognise the effort that went into producing it, by making a PayPal donation OF THEIR CHOICE

to the authors. This will ensure the incentive to provide support and the continued authoring

of new scripts.



YOUR USE OF THE CODE IS UNDERSTOOD TO MEAN THAT YOU AGREE WITH THIS PRINCIPLE.



You may donate via www.scripterlative.com, stating the URL to which the donation applies.
