How to remove comma from number which comes dynamically in .tpl file

Question

i want to remove comma from a number (e.g change 1,125 to 1125 ) in a .tpl file. The value comes dynamically like ${variableMap[key]}

Answer 1

var a='1,125';
a=a.replace(/\,/g,''); // 1125, but a string, so convert it to number
a=parseInt(a,10);

Hope it helps.
