Answer 1

You can use

var csqft_price = $('#testspan').html();
var number = Number(csqft_price.replace(/[^0-9\.]+/g, ""));

This was already posted on SO here.

Answer 2

The following tests whether the first character is a dollar-sign and if so takes the rest of the string:

var csqft_price = $('#testspan').html();
var price = +(csqft_price.charAt(0)==="$" ? csqft_price.substr(1) : csqft_price);

Of course, if you know that there will always be a dollar-sign you can just do this:

var price = +csqft_price.substr(1);

Note: I generally prefer the unary plus operator to convert a string to a number, so I've used that in my answer above - you can change +(...) to parseFloat(...) if you prefer.

Answer 3

I would replace all non digets and dots with nothing and make than a parseFloat:

var textValue = '$101.82';
var floatedValue = parseFloat(textValue.replace(/[^\d\.]/, ''));
alert(floatedValue);

Answer 4

Use this

var csqft_price = $('#testspan').html();
var price=parseFloat(csqft_price.replace('$',''));
alert(price);

And use price for calculation.
