Upgrading your version

If you are already using simpleCart(js), the only thing you need to change to use the new script is how you add it to your page:

<script src="simpleCart.js" type="text/javascript"></script> <script type="text/javascript">
simpleCart.email = "you@yours.com";
</script>

Check out the website, simplecartjs.com to learn about the new features, and let us know what you think!

var myNumber = 8.3;

alert( myNumber.toCurrency() );   //alerts "$8.30"

myNumber = 119427.23529;

alert( myNumber.toCurrency() );    //alerts "$119,427.24"

myNumber = 1231;

alert( myNumber.toCurrency( "€" ) );   //alerts "€1,231.00"

The dollar sign is default, but you can replace it with any symbol in the function call.

Just copy this code to your js file and enjoy! (This code also implements a reverse() method for strings that you might find useful.)

String.prototype.reverse=function(){
return this.split("").reverse().join("");
}
Number.prototype.withCommas=function(){
var x=6,y=parseFloat(this).toFixed(2).toString().reverse();
while(x<y.length){y=y.substring(0,x)+","+y.substring(x);x+=4;}
return y.reverse();
}
Number.prototype.toCurrency=function(){
return(arguments[0]?arguments[0]:"$")+this.withCommas();
}
