Answer 1

If you json_decode your string s, you will get a plain object with 3 owned properties. Then you can loop on those properties with the for..in construct:

var myOpts, s='{5: "White", 6: "Yellow", 7: "Pink"}';
eval('myOpts='+s); // or better, a json parser
for(var a in myOpts) {
    if(myOpts.hasOwnProperty(a)) {
       // your dom code here
    }
}
