How to convert a currency string to a double with jQuery or Javascript?

Question

I have a text box that will have a currency string in it that I then need to convert that string to a double to perform some operations on it.

\"$1,1

Answer 1

    $ 150.00
    Fr. 150.00
    € 689.00

I have tested for above three currency symbols .You can do it for others also.

    var price = Fr. 150.00;
    var priceFloat = price.replace(/[^\d\.]/g, '');

Above regular expression will remove everything that is not a digit or a period.So You can get the string without currency symbol but in case of " Fr. 150.00 " if you console for output then you will get price as

    console.log('priceFloat : '+priceFloat);

    output will be like  priceFloat : .150.00

which is wrong so you check the index of "." then split that and get the proper result.

    if (priceFloat.indexOf('.') == 0) {
            priceFloat = parseFloat(priceFloat.split('.')[1]);
    }else{
            priceFloat = parseFloat(priceFloat);
    }
