[Xerte] Trying to create a function with arguments

[Paul Swanson]

Why didn't I think of that? ;o)
 
Works perfectly, Julian.  Thanks!

	I wouldn't include all the aryEntities definitions in the
function, otherwise you are going through that code, rebuilding your
array, every time you call the function. There's no need to do that.
Instead, define the array somewhere near the top of the piece (in a
setup script is ideal, as that code will only run once, or somewhere in
the entry frame of the main framework):

	 

	myLookup = new Array();

	myLookup["&nbsp"] = "\u00A0"; 

	--etc--

	 

	Then there is no need to call a function - just lookup the value
you want:

	 

	myValue = myLookup[entity];

	 

	J

	I'm trying to create a function in Xerte that will display HTML
entities. The function takes the normal HTML entity name, and should
return the unicode equivalent, so I need to pass it an argument.

	From the Help, I see that Xerte does not recognize the keyword
'function' so I'm confused on how to pass it an argument. Here is the
function (found it through Google, then added some missing entities that
I think I might use someday):

	// create the entity mapping array     
	// which allows decoding html entities into their unicode
equivalents     

	function GetEntityArray(entity) { 
	    aryEntities = Array(); 
	    aryEntities[" "]   = "\u00A0"; // non-breaking space 
	    aryEntities["¡"]  = "\u00A1"; // inverted exclamation
mark 
	    aryEntities["¢"]   = "\u00A2"; // cent sign 
	    aryEntities["£"]  = "\u00A3"; // pound sign 
	    aryEntities["¤"] = "\u00A4"; // currency sign 
	    aryEntities["¥"]    = "\u00A5"; // yen sign 
	    aryEntities["€"]   = "\u20AC"; // Euro sign 
	    aryEntities["¦"] = "\u00A6"; // broken vertical bar
(|) 
	    aryEntities["§"]   = "\u00A7"; // section sign 
	    aryEntities["¨"]    = "\u00A8"; // diaeresis 
	    aryEntities["©"]   = "\u00A9"; // copyright sign 
	    aryEntities["®"]    = "\u00AE"; // registered sign 
	    aryEntities["™"]  = "\u2122"; // trademark sign 
	    aryEntities["°"]    = "\u00B0"; // degree sign 
	    aryEntities["±"] = "\u00B1"; // plus-minus sign 
	    aryEntities["¹"]   = "\u00B9"; // superscript one 
	    aryEntities["²"]   = "\u00B2"; // superscript two 
	    aryEntities["³"]   = "\u00B3"; // superscript three

valentine

	    return aryEntities[entity];     
	} 

	When I try to use the function to set a variable, I get
'undefined.' Any pointers? Incidentally, I think this would be a really
useful addition to the core Xerte.
