How can I change values inside an array of elements with jQuery?

Question

[<input id="unit_quantity_0" name="lines[0][quantity]" placeholder="Quantité" type="text" value="23,60">
,<input id="unit_quantity_2" name="lines[2][quantity]" placeholder="Quantité" type="text" value="5,60">]

How do I change the ',' in values to '.'

$("[id^=unit_quantity_]") returns the array.

Thanks.

How about:

$("[id^='unit_quantity_']").val(function (i, old) {
    return old.replace(/,/g, ".");
});

Example: http://jsfiddle.net/andrewwhitaker/325We/

Using the overload of .val that takes a function that lets you describe how to replace the old values.

$("[id^=unit_quantity_]").each(function(){
    var $this=$(this);
    $this.val( $this.val().replace(/,/g,'.'));
});
