// Image View Handler

// Processes the information contained in the imageInfo.js script to display the proper image

//
// Both scripts should be included in the HTML file just after the "body" tag in the following
// manner and order:
//

//

//-------------------------------------------------------------------------------------------------
// --- Free Code not in a Function ---
//
//get the id number of the image from the URL
//should be passed in the URL such as:
// ImageView.html?idNum=P2483
//

// Call this function via the body tag in the HTML code:

// Function to retrieve parameter from URL
//
// The way that the function is used is fairly simple. Let's say you have the following URL:
//
// http://www.foo.com/index.html?bob=123&frank=321&tom=213#top
//
// You want to get the value from the frank parameter so you call the javascript function as follows:
//
// var frank_param = gup( 'frank' );
function gup( name )
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return unescape(results[1]);
}
