Implementing Polymorphism in Javascript - how would this look? -


i'm trying make jump more oop style javascript approach, have not gotten right in javascript.

take following function example.

function positionalcss(array, cs, lcs){ /* define css circle based on number of circles */ //count array var arrcount = array.length; var t = []; var l = []; if(arrcount == 3){     t[0] ='15px';     l[0] = '240px';     t[1] = '345px';     l[1] = '440px';     t[2] = '345px';     l[2] = '40px'; } if(arrcount == 4){     t[0] ='-135px';     l[0] = '90px';     t[1] = '-10px';     l[1] = '290px';     t[2] = '220px';     l[2] = '270px';     t[3] = '315px';     l[3] = '90px'; } if(arrcount == 6){     t[0] ='-135px';     l[0] = '90px';     t[1] = '-10px';     l[1] = '290px';     t[2] = '220px';     l[2] = '270px';     t[3] = '315px';     l[3] = '90px';     t[4] = '210px';     l[4] = '-100px';     t[5] = '-10px';     l[5] = '-110px'; } $.each(array, function(i) {     var num = parseint(i);     //  console.log('$("' + lcs + ' ' + cs + '.handle-' + num + '").first().children("div");');          $(lcs + ' ' + cs + '.handle-' + num).first().children('div').css({         'position': 'absolute',         'top': t[num],         'left': l[num]     }); });

}

it's pretty horrendous, want pass in array, , depending on how many there are, organise positions of items based on this. guess based on size give properties? each tl represents top , left position of object?

i'd create object can lookup premade arrays of objects holding t/l values.

var counts = {   3: [     {t:'15px', l:'240px'},     {t:'345px', l:'440px'},     {t:'345px', l:'40px'}   ],   4: {     // above   },   5: {     // above   } };

and use in function:

function positionalcss(array, cs, lcs){     $.each(counts[array.length], function(i, obj) {         //  console.log('$("' + lcs + ' ' + cs + '.handle-' + + '").first().children("div");');          $(lcs + ' ' + cs + '.handle-' + i).first().children('div').css({             'position': 'absolute',             'top': obj.t,             'left': obj.l         });     }); }
