jQuery: match currency with a regular expression

In the following:

<span>This cost $15.99 per item</span>

how do I return "$15.99" using jquery? The value can also be for example "$7".

$("span").filter(function() {
    return this.text().match('\$\d+(\.\d+)?');
});

You can use just the match of match('\$\d+(\.\d+)?'), but the above function will filter spans that contain the match.

The expression would be something similar to \$\d+(\.\d+)? or \$\d+(?:\.\d+)? to get rid of the sub group.

demo

alert($('span').text().match(/\$\d+.\d+/));

but there is a code here for the regex to be more precise...

Will the text always be "This cost [your price] per item", or is the text also arbitrary?

If the text is fixed, you can just $.replace() everything except the price (in two steps) with an empty string.
