    21 THIS IS A SUPPORTED SCRIPT 
    22 ~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    23 It's in everyone's interest that every download of our code leads to a successful installation. 
    24 To this end we undertake to provide a reasonable level of email-based support, to anyone  
    25 experiencing difficulties directly associated with the installation and configuration of the 
    26 application. 
    27  
    28 Before requesting assistance via the Feedback link, we ask that you take the following steps: 
    29  
    30 1) Ensure that the instructions have been followed accurately. 
    31  
    32 2) Ensure that either: 
    33    a) The browser's error console ( Ideally in FireFox ) does not show any related error messages. 
    34    b) You notify us of any error messages that you cannot interpret. 
    35  
    36 3) Validate your document's markup at: http://validator.w3.org or any equivalent site.    
    37     
    38 4) Provide a URL to a test document that demonstrates the problem. 
    39   
    40 Installation 
    41 ~~~~~~~~~~~~ 
    42  Save this text/file as 'recoverscroll.js', and place it in a folder associated with your web pages. 
    43  
    44  Insert the following tags in the <head> section of the document to be scrolled: 
    45  
    46  <script type='text/javascript' src='recoverscroll.js'></script> 
    47  
    48  (If recoverscroll.js resides in a different folder, include the relative path) 
    49  
    50 Configuration 
    51 ~~~~~~~~~~~~~ 
    52  The script is initialised by calling the function RecoverScroll.init(), using the onload event. 
    53  Provided that you have no other script that uses the onload event, either of the following two 
    54  methods can be used: 
    55  
    56   <body onload='RecoverScroll.init()'> 
    57  
    58   <script type='text/javascript'> 
    59    window.onload=function(){RecoverScroll.init()} 
    60   </script> 
    61  
    62  IMPORTANT - If you have (or suspect you have) other scripts that use the onload event, you must 
    63  prevent a conflict by using the following alternative initialisation. This code should be located 
    64  at any point below the installation of the other scripts. 
    65  
    66   <script type='text/javascript'> 
    67    RecoverScroll.addToHandler(window,'onload',function(){RecoverScroll.init()}); 
    68   </script> 
    69  
    70  When installing on multiple pages, on each page you must provide a /unique/ name as a quoted 
    71  parameter to the init function. This applies to whichever initialisation method is used, i.e.: 
    72  
    73  <body onload="RecoverScroll.init('homePage')" > 
    74  
    75  -OR- 
    76  
    77  <script type='text/javascript'> 
    78    window.onload=function(){RecoverScroll.init('homePage')} 
    79  </script> 
    80  
    81  -OR- 
    82  
    83  <script type='text/javascript'> 
    84    RecoverScroll.addToHandler(window,'onload',function(){RecoverScroll.init('homePage')}); 
    85  </script> 
    86  
    87  
    88  NOTE. This script also uses the onscroll event. If any other installed scripts are known use this 
    89        event, they should be initialised ealier. 
    90  
    91 Combining with SoftScroll 
    92 ~~~~~~~~~~~~~~~~~~~~~~~~~ 
    93 To combine RecoverScroll with SoftScroll, simply install 'softscroll.js' by placing these tags 
    94 /prior/ to the RecoverScroll <script> tags: 
    95  
    96 <script type='text/javascript' src='softscroll.js'></script> 
    97
