VARIABLE1,VARIABLE1,PROPERTY1,PROPERTY2...PROPERTY6|/
You have a number of lines - in the above format.
They are in a single variable.
You want to take it
and create a multi-dimensional Array.
MORE than that - you want it more in an hash ( list, dictionary ) format.
I thought it couldn't be done in JS.
I finally hit a problem which i couldn't overcome without
working out how to handle this.
For anyone that doesn't know how these look:
Code:
[VARIABLE 1a] | - [VARIABLE 2a] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 3a] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 4a] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 5a] = [ PROPERTY 1, PROPERTY 2 ...][VARIABLE 1b] | - [VARIABLE 2b] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 3b] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 4b] = [ PROPERTY 1, PROPERTY 2 ...] | - [VARIABLE 5b] = [ PROPERTY 1, PROPERTY 2 ...]
Now you want to be able to access these by name but not
have multiples, and not overwrite the previous value.
The method I've ended up with looks like this:
Code:
MAKES = new Array();TYPES = new Array();var str='/ECMN,AVIS,FORD,MONDEO,GREEN,1.5|/ECMN,HERTZ,FORD,MONDEO,GREEN,1.5|/ECAR,HERTZ,FORD,MONDEO,GREEN,1.5|/';var all = str.split(//|/);for (i=0;i<all.length;i++){ var set = all[i].split(/,/); if (!TYPES[set[0]]){ TYPES.push(set[0]); TYPES[set[0]] = 1; } if (!MAKES[set[1]]){ MAKES.push(set[1]); MAKES[set[1]] = 1; } l=set[0]+"['"+set[1]+"']=new Array('"+set[2]+"','"+set[3]+"','"+set[4]+"','"+set[5]+"')"; try { eval(l); } catch(e) { eval(set[0]+' = new Array();'); eval(l); } }alert(eval(TYPES[1]+'["'+MAKES[1]+'"]'));alert(MAKES);Effectively this gives you the ablility to say:
alert ( ECMN['AVIS'] ) and you'll get an array returned
containing Ford Mondeo Green 1.5!
Now i don't know if i'm being stupid - but to me that
seems like a very slight breakthrough.
Am i rediscovering the wheel, and is there a common way of doing this?
Can anyone think of how to improve this?
