Question

I’ve got a problem with replace not working.

alert($('input#membership_edc').next("label").html().replace(/£/g, ""));

The value of the label after the input would be £24.00, but I want to do a math on that value then put it back with the new value. It’s not removing the pound sign.

What’s wrong? Thanks.

To read/modify/write use the function parameter version of .html():

$('input#membership_edc').next("label").html(function(index, old) {
    var n = parseFloat(old.replace('£', '');
    return n + 10;
});

would replace ‘£24.00′ with ’34’.
