jquery regex replace from select text

Question

I have some text I fetch inside here but only want the currency... How can I get rid of the other values?

I tried this, but didn't have any luck.

var symbol = $("div.price > h5 > div.num").text().replace(/[\d.]*/, "");

Here's the example html, the selector I'm using works fine, just not the replace.

<div class="price">
        <h5 class="biguns">
            <div class="num">
                €12.28
            </div>
            Lowest Price Per Night
        </h5>
    </div>

Answer 1

The dot must be escaped othwerwise it will match every character and you must set the global modifier:

var symbol = $("div.price > h5 > div.num").text().replace(/[\d\.]+/g, "");

Answer 2

Test your regular expression before using it, I'm definitely not a regex expert which is why I always test it first :)

[\d|\.]+

Answer 3

var symbol = $("div.price > h5 > div.num").text().replace(/\d+\.?\d+/, "");

Answer 4

If the currency is always the first character and it's one character long, you could easily get it with

var symbol = $(".num").text().substr(0,1);
