Convert to currency format

Question

Is there a built in function of JavaScript to convert a string into a currency format?

For example

var a = \'1234\';
a.convertToCurrency();   // retu

Although this is an old post. Nonetheless, this worked in for me in my own case:

var a = parseInt("1234");
console.log("$"+number_format(a));

var number_format = function(total) {
   return total.toFixed(2).replace(/\d(?=(\d{3})+\.)/g, '$&,');
};
