[Xerte] Trying to create a function with arguments

[Julian Tenney]

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];

Subject: [Xerte] Trying to create a function with arguments

 

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["¥"]    = "\u00A5"; // yen sign 
    aryEntities["€"]   = "\u20AC"; // Euro sign

    aryEntities["♦"]  = "\u2666"; // Diamond suit 
    
    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.
