Javascript “Replace” not working on string returned via jQuery

Question

I'm trying to convert a currency string to a number. I'm using a replace function with a regexp that I've used successfully in a similar context before.

The currency string is captured here, in part of an "each" loop:

var unitGridPrice = jQuery(this).find(".clsPriceGridDtlPrice").html();

The result is that unitGridPrice is a currency string, something like "$2.75". I'm trying to convert it to a number here:

var priceToConvert = unitGridPrice;
var unitGridPriceNo = Number(priceToConvert.replace(/[^0-9\.]+/g, ''));

However with that last line in place, the script will not run.

If I use the value of priceToConvert it correctly displays the currency text string, so I believe the string feeding the replace function is correct.

if I change "var priceToConvert = unitGridPrice" to "var priceToConvert = "$2.75" the script properly returns 2.75. I can copy and past the value that unitGridPrice displays into the text string I'm testing with and it works, but with the variable there the script dies.

I've tried removing the regex, changing the replace to .replace('$', '') and again the script stops with the variable in place but works if I test with a fixed string.

I'm really stumped. Help??!! Thank you!!!

Answer 1

i had some problem while try to get number from string also, little time ago. the problem is the regex, so i changed the regex like code below.

var id = element.name.replace ( /[^\d.]/g, '' );

element.name above is like input_21,input_22, etc. and i wanna get only the number(21,22). hope it can help you. :)
